Can anyone suggest me the coding of state changes in react-redux, basically thing will be like this ,We will have STATES=[UNINITIATED,INITIATED,INPROGRESS,FAILED],with initial status as uninitiated, so I will have a button, which I will click and the initial state will be changed to Initiated and button will be disabled, also it will fetch some kind of response from bff API, so for now, lets consider it(hardcoded) as success: 200 request, so after this the state will be showing in progress and also a toast will be displayed, also it will show failed if it request a fail message from the bff API and the state will again be uninitiated, also the button will be disabled after the first click and will only been enabled if the status becomes failed.

The problem is the library is configured such that no one can send many requests to google. I want to send 1000 requests per day and to achieve that I have to add fake_useragent to module. I tried a lot but when I try to add fake user agent to header it gives error. I am not a pro so I must have done wrong myself. Can anyone help me add fake_useragent to module(people_also_ask). here is working code to get question/answer.
from encodings import utf_8
import people_also_ask as paa
from fake_useragent import UserAgent
ua = UserAgent()
while True:
input("Please make sure the queries are in \\query.txt file.\npress Enter to continue...")
try:
query_file = open("query.txt","r")
queries = query_file.readlines()
query_file.close()
break
except:
print("Error with the query.txt file...")
for query in queries:
res_file = open("result.csv","a",encoding="utf_8")
try:
query = query.replace("\n","")
except:
pass
print(f'Searching for "{query}"')
questions = paa.get_related_questions(query, 14)
questions.insert(0,query)
print("\n________________________\n")
main_q = True
for i in questions:
i = i.split('?')[0]
try:
answer = str(paa.get_answer(i)['response'])
if answer[-1].isdigit():
answer = answer[:-11]
print(f"Question:{i}?")
except Exception as e:
print(e)
print(f"Answer:{answer}")
if main_q:
a = ""
b = ""
main_q = False
else:
a = "<h2>"
b = "</h2>"
res_file.writelines(str(f'{a}{i}?{b},"<p>{answer}</p>",'))
print("______________________")
print("______________________")
res_file.writelines("\n")
res_file.close()
print("\nSearch Complete.")
input("Press any key to Exit!")

Graph API - BadRequest on sending channel messages with #mention

We had some code that has been working for the past 10 months (since it was developed) and just stopped working this afternoon. It's a WebAPI code to send a channel message mentioning the bot and a user, which now is returning "Bad Request. Invalid request body was sent."
If the "Mentions" property is not provided, the call works, and the message is sent without the #mentions. So, I wonder if there was a breaking change in this API that's now expecting a different format for the "Mentions" property.
It's quite simple to reproduce by following the example code found in the Microsoft Graph documentation.
I'm posting here in the hope some fellow dev spots something obvious or is aware of an alternative way of using the API that it might stop complaining, as Microsoft takes forever to reply.
Here's the code we have that can lead me to discover the issue:
private async Task SendMentionToTheBotAsync(GraphServiceClient onBehalfOfClient, string userName, string teamId, string channelId)
{
var supportAgentUser = await onBehalfOfClient.Me.Request().GetAsync();
var chatMessage = new ChatMessage
{
Body = new ItemBody
{
ContentType = BodyType.Html,
Content = $"<at id=\"0\">{Configuration["BotName"]}</at>: This is the start of the conversation between {userName} and <at id=\"1\">{supportAgentUser.DisplayName}</at>."
},
Mentions = new List<ChatMessageMention>
{
new ChatMessageMention
{
Id = 0,
MentionText = Configuration["BotName"],
Mentioned = new IdentitySet
{
Application = new Identity
{
DisplayName = Configuration["BotName"],
Id = Configuration["BotAppId"],
AdditionalData = new Dictionary<string,object>
{
{
"applicationIdentityType", "bot"
}
}
}
}
},
new ChatMessageMention
{
Id = 1,
MentionText = supportAgentUser.DisplayName,
Mentioned = new IdentitySet
{
User = new Identity
{
DisplayName = supportAgentUser.DisplayName,
Id = supportAgentUser.Id,
AdditionalData = new Dictionary<string,object>
{
{
"userIdentityType", "aadUser"
}
}
}
}
}
}
};
await onBehalfOfClient.Teams[teamId].Channels[channelId].Messages
.Request()
.AddAsync(chatMessage);
}
Microsoft Support responded with :
"Thank you for contacting Microsoft Support.
I understand the issue is related to the post messages to Teams. Based on the screenshot, it seems you are using mention to a channel. It's possible that you are using key "conversationIdentityType#odata.type" in your request.
Could you please try to remove "conversationIdentityType#odata.type" key from the request body and try again. It should work. It is because deployment is on the way in the Asia region. Once it's 100% rolled out, this key WILL NOT be entertained in the request."
Removed the key and it worked for me.
Paulo,
Unfortunately i am not a programmer. I am using Graph calls in a Microsoft 365 Power Automate workflow. I have an app that i use to get the Authorisation Bearer token and then post to Teams messages using a graph HTTP action.
Here is the syntax of the HTTP ( purple items are variables if u r not familiar with Flow )

Paypal Payflow Transparent Redirect, SecureToken with AJAX?

I'm working on a C# VS2012 Framework 4.5 MVC application that is trying to become PCI compliant using Payflow Pro (https://pilot-payflowpro.paypal.com). We've been using PayflowPro for years, and this is what I have to use. From my reading it seems that I should use the Transparent Redirect so I'm not posting anything private to my webserver, though I don't know if I need that with how I'm hoping to handle this. I also have a few questions...
How I think this all works:
My understanding is that you need a securetoken (communication to Paypal, trip 1). Then you post the secure data (CC, exp, security code) including the securetoken (communication to Paypal, trip 2) and receive the authorization and transactionID of the sale.
How I'm hoping to do it:
I'm intending on having a form that will have all the info (user details, shipping details, and CC info), and when the user presses the purchase button, I'll use AJAX to process trip 1 to my server (no secure user info sent). Here I'll create the URL + params and send paypal my un/pw info to retrieve the token (all from my server). The response will be returned to the client and, if successful, I'll then directly communicate via AJAX to Paypal's Gateway server, this time sending the secure CC info + token (trip #2). Based on the response to trip #2, I'll let the user know what's up with their purchase. Trip 2 shouldn't need my Paypal UN/PW info as it could easily be see on the client, and I'm including the SecureToken which SHOULD identify the original transaction. From what I've explained I don't see a need for Transparent Redirect. Or am I missing something here?
Also, what Transaction Type do I want to use? Create an 'Authorization' for trip #1, then a 'Sale' for trip #2?
So here's the nitty gritty coding type stuff:
For my R&D testing I'm building my own name/value pair parameter string (see below) and communicating to the gateway server via WebRequest through their sandbox/test url (pilot-payflowpro.paypal.com). I do get a successful response and SECURETOKEN back. Initial request (shown below) for secure token is TRXTYPE = A (Authorization), no card info is sent. Do I want to authorize first?
Here are my parameters (might include shipto info as well, but it's not listed below):
USER=myAuthUserName
&VENDOR=myAuthUserName
&PARTNER=myPartner
&PWD=myPassword
&AMT=21.43
&BILLTOFIRSTNAME=FName
&BILLTOLASTNAME=LName
&BILLTOSTREET=123 Main Street
&BILLTOSTREET2=Apt 203B
&BILLTOCITY=MyCity
&BILLTOSTATE=CA
&BILLTOZIP=77777
&BILLTOPHONENUM=4444444444
&EMAIL=myemail#somedomain.com
&CURRENCY=USD
**&TRXTYPE=A**
&SILENTTRAN=TRUE
&CREATESECURETOKEN=Y
&SECURETOKENID=a99998afe2474b1b82c8214c0824df99
As I said, I get a successful response and move to the next step of sending the secure data (CC#, EXPDATE, security code). When I remove my UN/PW/VENDOR/Partner info from the params I get an error due to invalid user authentication. But, seeing I'm dynamically building this 2nd call I can't have my paypal un/pw there. What am I missing? Anyone offer assistance with this or the other questions from above?
Please let me know if I need any clarification to be added. Thanks in advance for your time!
After spending a bunch of time with a Paypal engineer I've successfully figured out a solution for the Paypal's Payflow Transparent Redirect without hosted pages (have own payment page). Again, here's the documentation which, per the engineer, is pretty confusing: Payflow API Documentation. Also, the code isn't optimized as it was just a R&D app, but as a whole, it is working for me. Just an example and explanation, and I'm sure there are better ways of doing individual steps. Hope this helps and allows you to bypass some of the roadblocks that have been slowing down your Paypal Payflow integration.
YES, it is PCI compliant in that no secure customer data will hit your own servers. Remember that PCI compliance is pretty complicated and involved but this is big part of it. Ok, so I'll explain what I did to make this work in a MVC C# environment. I'll explain the steps here, then include code below.
CLIENT: Client finishes adding items to the cart and presses BUY button. Javascript handles the button click, doesn't submit, and takes you to the next step.
CLIENT --> SERVER: AJAX function POSTS to server method to contact Paypal for the single-use secure token. This communication identifies YOU (the merchant) to paypal with your authentication, a unique transaction id (a guid), and non secure details about the transaction (total, billing info, shipping info, return URL details). This way, all your merchant personal acct info is secure (web server to Paypal).
SERVER --> CLIENT: From the transaction above you'll receive a parameter string that contains the secure token (among other stuff, see method with example). Using this piece of info, I dynamically create my url that I'll eventually need on the client for the transparent redirect part, and send the url string back to the client.
CLIENT: Using the url that was returned in step #3, I complete the URL by adding the needed credit card parameters using jQuery.
CLIENT --> PAYPAL: This is where I didn't understand what to do. While step #2 was a post, this step will be a REDIRECT. Sure, that seems appropriate seeing it's called 'transparent redirect', but that part just didn't make sense to me. So, once your entire URL is complete, you'll literally redirect the window to Paypal for processing your transaction.
PAYPAL --> SERVER: PayPal posts back to one of the URLs you included in step 2 (to a public method on one of my controllers), and I read the response object and parse the parameters.
Easy, right? Perhaps, but for me step 5 caused me big problems. I was using a POST and didn't understand why I kept getting errors on the response. It was an html page with something about an invalid merchant or authentication. Remember to redirect, not post for step #5.
CODE:
STEP 1: onclick attribute on button to call GetToken function.
STEP 2 and STEP 3:
client-side:
function GetToken() {
$.ajax({
url: '#Url.Action("GetToken", "MyController")',
type: 'POST',
cache: 'false',
contentType: 'application/json; charset=utf-8',
dataType: 'text',
success: function (data) {
// data is already formatted in parameter string
SendCCDetailsToPaypal(data);
},
//error:
//TODO Handle the BAD stuff
});}
Server Side:
I have separate methods used to build all the parameter values needed for the token request. First three build: authentication, transaction details, transparent redirect. I keep urls and payflow acct info in a web.config file. Last method, ProcessTokenTransaction, does all the heavy lifting to contact Paypal via WebRequest, and then parse it into the URL that will be sent back to the client. This method should be refactored for a cleaner delivery, but I'll leave that up to you. ParseResponse is a method that populates a simple model that I created, and returns that model.
URL for token (sandbox): https://pilot-payflowpro.paypal.com
THIS IS DIFFERENT THAN THE TOKEN URL!! Used in the PaypalTranactionAPI config value.
URL for transaction: (sandbox) https://pilot-payflowlink.paypal.com

}

{
var nameValues = HttpUtility.ParseQueryString(response);
int result = -999; // invalid result to guarantee failure
int.TryParse(nameValues.Get(TokenResponse.ResponseParameters.RESULT.ToString()), out result);
// retrieving response message
var responseMessage = nameValues.Get(TokenResponse.ResponseParameters.RESPMSG.ToString());
// retrieving token value, if any
var secureToken = nameValues.Get(TokenResponse.ResponseParameters.SECURETOKEN.ToString());
var reference = nameValues.Get(TokenResponse.ResponseParameters.PNREF.ToString());
var authCode = nameValues.Get(TokenResponse.ResponseParameters.AUTHCODE.ToString());
var cscMatch = nameValues.Get(TokenResponse.ResponseParameters.CSCMATCH.ToString());
// populating model with values
var tokenResponse = new TokenResponse
{
Result = result,
ResponseMessage = responseMessage,
SecureToken = secureToken,
TransactionIdentifierToken = requestId,
TransactionType = transactionType,
ReferenceCode = reference,
AuthorizationCode = authCode,
CSCMatch = cscMatch
};
return tokenResponse;
}
STEP 4 and STEP 5:
Back to Client Side:
Here I use the URL built from the previous steps and add the final needed params (secure credit card info) using jQuery and then REDIRECT to Paypal.
function SendCCDetailsToPaypal(secureParm) {
//alert('in SendCCDetailsToPaypal:' + secureParm);
var secureInfo = '&ACCT=' + $('#ccNumber').val() + '&EXPDATE=' + $("#expMonth").val() + $("#expYear").val() + "&CSC=" + $('#ccSecurityCode').val();
secureInfo = secureParm + secureInfo;
window.location.replace(secureInfo);
}
STEP 6:
Paypal will post back to one of the following methods: Cancel, Error, or Return (name the methods anything you want in the token request). Parse the Response and look at the variables returned from Paypal, particularly the RESULT and RESPMSG. Read the documentation for specifics as you can incorporate address validation and a bunch of other features. Based on the response, display what's appropriate.
server side:
public ActionResult Cancel()
{
var result = ParseRequest(HttpUtility.UrlDecode(Request.Params.ToString()));
//return View("Return", result);
}
public ActionResult Error()
{
var result = ParseRequest(HttpUtility.UrlDecode(Request.Params.ToString()));
return View("Return", result);
}
public ActionResult Return()
{
var result = ParseRequest(HttpUtility.UrlDecode(Request.Params.ToString()));
return View("Return", result);
}
Hope this helps, and good luck! I'll answer clarification questions as I'm able. Thanks for checking this out, and remember to pay it forward.
I was able to use RichieMN's answer to get a working Transparent Redirect happening. However, the problem with doing a redirect with window.location.replace in the SendCCDetailsToPaypal function is that you're passing the data on a GET string.
This works on the PayFlow Gateway side, but when they send the customer's browser back to your ResponseURL, your Apache logs will show the whole payflowlink.paypal.com URL, including the GET string as the referrer in your Apache access logs! That GET string includes the Credit Card number and now you have just lost your PCI compliance!
To alleviate this problem, you can either put the SecureToken and SecureTokenID into your Credit Card entry form, and POST it directly to payflowlink.paypal.com, or you can rewrite the SendCCDetailsToPaypal function to build a form and submit it, like this:
function SendCCDetailsToPaypal() {
var parameters = {
"SECURETOKEN": secureToken,
"SECURETOKENID": secureTokenID,
"ACCT": $("#ccNumber").val(),
"EXPDATE": $("#expMonth").val() + $("#expYear").val(),
"CSC": $("#ccSecurityCode").val()
};
var form = $('<form></form>');
form.attr("method", "post");
form.attr("action", "https://pilot-payflowlink.paypal.com");
$.each(parameters, function(key, value) {
var field = $('<input></input>');
field.attr("type", "hidden");
field.attr("name", key);
field.attr("value", value);
form.append(field);
});
$(document.body).append(form);
form.submit();
}
Since that form transfers the data via POST, when your server gets the result POST back, the referrer does not contain any sensitive data, and your PCI compliance is maintained.

Paypal IPN status is always invalid?

Am getting Invalid response from IPN, some people mentioned like return url and notification url shouldn't be same but i changed in that way also even am getting same result.
Here is my code for making payment,payment is working fine.
Paypal paypal = new Paypal();
paypal.cmd = "_xclick";
paypal.business = ConfigurationManager.AppSettings["BusinessAccountKey"];
bool useSandbox = Convert.ToBoolean(ConfigurationManager.AppSettings["UseSandbox"]);
paypal.cancel_return = "http://www.patronalerts.com/";
//paypal.#return = ConfigurationManager.AppSettings["ReturnURL"];
paypal.#return = "http://www.patronalerts.com/";
paypal.notify_url = ConfigurationManager.AppSettings["NotifyURL"];
paypal.currency_code = ConfigurationManager.AppSettings["CurrencyCode"];
paypal.item_name = "Test Product";
paypal.amount = "10";
url = "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd="+paypal.cmd +"&business="+ paypal.business+"&no_shipping=&return="+paypal.#return+"&cancel_return="+paypal.cancel_return+"&currency_code="+paypal.currency_code+"&item_name="+ paypal.item_name+"&amount="+ paypal.amount;
But the problem with below code or configuration in paypal account i can't guess. most probably with paypal configuration because every one using this code.
string strSandbox = "https://www.sandbox.paypal.com/cgi-bin/webscr";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(strSandbox);
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
byte[] param = Request.BinaryRead(System.Web.HttpContext.Current.Request.ContentLength);
string strRequest = Encoding.ASCII.GetString(param);
string strResponse_copy = strRequest; //Save a copy of the initial info sent by PayPal
strRequest += "&cmd=_notify-validate";
req.ContentLength = strRequest.Length;
StreamWriter streamOut = new StreamWriter(req.GetRequestStream(), System.Text.Encoding.ASCII);
streamOut.Write(strRequest);
streamOut.Close();
StreamReader streamIn = new StreamReader(req.GetResponse().GetResponseStream());
string strResponse = streamIn.ReadToEnd();
streamIn.Close();
if (strResponse == "VERIFIED")
{
NameValueCollection these_argies = HttpUtility.ParseQueryString(strResponse_copy);
string user_email = these_argies["payer_email"];
string pay_stat = these_argies["payment_status"];
if (pay_stat.Equals("Completed"))
{
ViewBag.Result = "Kishore Suceess";
}
}
else if (strResponse == "INVALID")
{
ViewBag.Result = "invalids";
}
else
{
ViewBag.Result = "Ipn data for manual investigation";
}
If any body help me out would be appriciated.
An “INVALID” message is due to the following reasons:
- Check that your are posting your response to the correct URL, which is https://www.sandbox.paypal.com/cgi-bin/webscr or https://www.paypal.com/cgi-bin/webscr, depending on whether you are testing in the Sandbox or you are live, respectively.
- Verify that your response to the test IPN message contains exactly the same variables and values as the test message and that they are in the same order as in the test message. Finally, verify that the original variables are preceded by a cmd=_notify-validate variable.
- Ensure that you are encoding your response string and are using the same character encoding as used by the test IPN message. (for example, I can see that he is using letters with umlaut and other symbols like “/”, etc).
With regard to the last point, the merchant can try to change the encoding language in use in his PayPal account, following the steps below:
Login on you PayPal account
Click on Profile
Click on “My Selling Preferences” tab
Click on “PayPal Button Language Encoding” (at the end of the page)
Click on "Other Options"
Select from the drop down menu: UTF-8
Choose the same charset also for the second option, which is related to IPN
Click “Save”
If the issue persists, we recommend to review the script in use, PayPal has some IPN code samples available at: https://github.com/paypal/ipn-code-samples
For additional information I include the link: https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNTesting/#id091GFE00WY4

Google+ insert moment using google-api-dotnet-client

I am trying to write an activity in Google+ using the dotnet-client. The issue is that I can't seem to get the configuration of my client app correctly. According to the Google+ Sign-In configuration and this SO question we need to add the requestvisibleactions parameter. I did that but it did not work. I am using the scope https://www.googleapis.com/auth/plus.login and I even added the scope https://www.googleapis.com/auth/plus.moments.write but the insert still did not work.
This is what my request url looks like:
https://accounts.google.com/ServiceLogin?service=lso&passive=1209600&continue=https://accounts.google.com/o/oauth2/auth?scope%3Dhttps://www.googleapis.com/auth/plus.login%2Bhttps://www.googleapis.com/auth/plus.moments.write%26response_type%3Dcode%26redirect_uri%3Dhttp://localhost/%26state%3D%26requestvisibleactions%3Dhttp://schemas.google.com/AddActivity%26client_id%3D000.apps.googleusercontent.com%26request_visible_actions%3Dhttp://schemas.google.com/AddActivity%26hl%3Den%26from_login%3D1%26as%3D-1fbe06f1c6120f4d&ltmpl=popup&shdf=Cm4LEhF0aGlyZFBhcnR5TG9nb1VybBoADAsSFXRoaXJkUGFydHlEaXNwbGF5TmFtZRoHQ2hpa3V0bwwLEgZkb21haW4aB0NoaWt1dG8MCxIVdGhpcmRQYXJ0eURpc3BsYXlUeXBlGgdERUZBVUxUDBIDbHNvIhTeWybcoJ9pXSeN2t-k8A4SUbfhsygBMhQivAmfNSs_LkjXXZ7bPxilXgjMsQ&scc=1
As you can see from there that there is a request_visible_actions and I even added one that has no underscore in case I got the parameter wrong (requestvisibleactions).
Let me say that my app is being authenticated successfully by the API. I can get the user's profile after being authenticated and it is on the "insert moment" part that my app fails. My insert code:
var body = new Moment();
var target = new ItemScope();
target.Id = referenceId;
target.Image = image;
target.Type = "http://schemas.google.com/AddActivity";
target.Description = description;
target.Name = caption;
body.Target = target;
body.Type = "http://schemas.google.com/AddActivity";
var insert =
new MomentsResource.InsertRequest(
// this is a valid service instance as I am using this to query the user's profile
_plusService,
body,
id,
MomentsResource.Collection.Vault);
Moment result = null;
try
{
result = insert.Fetch();
}
catch (ThreadAbortException)
{
// User was not yet authenticated and is being forwarded to the authorization page.
throw;
}
catch (Google.GoogleApiRequestException requestEx)
{
// here I get a 401 Unauthorized error
}
catch (Exception ex)
{
} `
For the OAuth flow, there are two issues with your request:
request_visible_actions is what is passed to the OAuth v2 server (don't pass requestvisibleactions)
plus.moments.write is a deprecated scope, you only need to pass in plus.login
Make sure your project references the latest version of the Google+ .NET client library from here:
https://developers.google.com/resources/api-libraries/download/stable/plus/v1/csharp
I have created a project on GitHub showing a full server-side flow here:
https://github.com/gguuss/gplus_csharp_ssflow
As Brettj said, you should be using the Google+ Sign-in Button as demonstrated in the latest Google+ samples from here:
https://github.com/googleplus/gplus-quickstart-csharp
First, ensure you are requesting all of the activity types you're writing. You will know this is working because the authorization dialog will show "Make your app activity available via Google, visible to you and: [...]" below the text that starts with "This app would like to". I know you checked this but I'm 90% sure this is why you are getting the 401 error code. The following markup shows how to render the Google+ Sign-In button requesting access to Add activities.
<div id="gConnect">

Assuming you have a PlusService object with the correct activity type set in data-requestvisibleactions, the following code, which you should be able to copy/paste to see it work, concisely demonstrates writing moments using the .NET client and has been tested to work:
Moment body = new Moment();
ItemScope target = new ItemScope();
target.Id = "replacewithuniqueforaddtarget";
target.Image = "http://www.google.com/s2/static/images/GoogleyEyes.png";
target.Type = "";
target.Description = "The description for the activity";
target.Name = "An example of add activity";
body.Target = target;
body.Type = "http://schemas.google.com/AddActivity";
MomentsResource.InsertRequest insert =
new MomentsResource.InsertRequest(
_plusService,
body,
"me",
MomentsResource.Collection.Vault);
Moment wrote = insert.Fetch();
Note, I'm including Google.Apis.Plus.v1.Data for convenience.
Ah it's that simple! Maybe not? I am answering my own question and consequently accept it as the answer (after a few days of course) so others having the same issue may be guided. But I will definitely up-vote Gus' answer for it led me to the fix for my code.
So according to #class answer written above and as explained on his blog the key to successfully creating a moment is adding the request_visible_actions parameter. I did that but my request still failed and it is because I was missing an important thing. You need to add one more parameter and that is the access_type and it should be set to offline. The OAuth request, at a minimum, should look like: https://accounts.google.com/o/oauth2/auth?scope=https://www.googleapis.com/auth/plus.login&response_type=code&redirect_uri=http://localhost/&request_visible_actions=http://schemas.google.com/AddActivity&access_type=offline.
For the complete and correct client code you can get Gus' example here or download the entire dotnet client library including the source and sample and add what I added below. The most important thing that you should remember is modifying your AuthorizationServerDescription for the Google API. Here's my version of the authenticator:
public static OAuth2Authenticator<WebServerClient> CreateAuthenticator(
string clientId, string clientSecret)
{
if (string.IsNullOrWhiteSpace(clientId))
throw new ArgumentException("clientId cannot be empty");
if (string.IsNullOrWhiteSpace(clientSecret))
throw new ArgumentException("clientSecret cannot be empty");
var description = GoogleAuthenticationServer.Description;
var uri = description.AuthorizationEndpoint.AbsoluteUri;
// This is the one that has been documented on Gus' blog site
// and over at Google's (https://developers.google.com/+/web/signin/)
// This is not in the dotnetclient sample by the way
// and you need to understand how OAuth and DNOA works.
// I had this already, see my original post,
// I thought it will make my day.
if (uri.IndexOf("request_visible_actions") < 1)
{
var param = (uri.IndexOf('?') > 0) ? "&" : "?";
description.AuthorizationEndpoint = new Uri(
uri + param +
"request_visible_actions=http://schemas.google.com/AddActivity");
}
// This is what I have been missing!
// They forgot to tell us about this or did I just miss this somewhere?
uri = description.AuthorizationEndpoint.AbsoluteUri;
if (uri.IndexOf("offline") < 1)
{
var param = (uri.IndexOf('?') > 0) ? "&" : "?";
description.AuthorizationEndpoint =
new Uri(uri + param + "access_type=offline");
}
// Register the authenticator.
var provider = new WebServerClient(description)
{
ClientIdentifier = clientId,
ClientSecret = clientSecret,
};
var authenticator =
new OAuth2Authenticator<WebServerClient>(provider, GetAuthorization)
{ NoCaching = true };
return authenticator;
}
Without the access_type=offline my code never worked and it will never work. Now I wonder why? It would be good to have some explanation.

WebClient NotFound error but working with HttpWebRequest/Response

In my WinPhone app I'm accessing a REST service.
At the beginnings I was using this code:
WebClient wc = new WebClient();
wc.Credentials = credentials;
wc.Headers["App-Key"] = appKey;
wc.DownloadStringCompleted +=
(o, args) => MessageBox.Show(args.Error == null ? "OK" : "Error");
wc.DownloadStringAsync(uri);
but it suddenly stopped working returning me a "The remote server returned an error: NotFound" error. After a google session and some clicks in the control panel, I didn't get it to work.
I decided to try this other way:
HttpWebRequest request = HttpWebRequest.CreateHttp(uri);
request.Credentials = credentials;
request.Headers["App-Key"] = appKey;
request.BeginGetResponse(asResult =>
{
var response = request.EndGetResponse(asResult) as HttpWebResponse;
StreamReader reader = new StreamReader(response.GetResponseStream());
string responseString = reader.ReadToEnd();
Dispatcher.BeginInvoke(
() => MessageBox.Show(response.StatusCode.ToString()));
}, null);
and it works.
I also tried to run the first snipped pointing the URI to google's home page and it works (I had to remove the credentials, of course).
Can anyone explain what's going on?
UPDATE
I managed to get it working by replacing the
wc.Credentials = new NetworkCredentials(username, password);
with
wc.Headers["Authorization"] = "Basic someBase64encodedString";
but i still wonder what happened and which are the differences between the first and the second line.
PS: the test URI is: https://api.pingdom.com/api/2.0/checks but you will need an app-key from them.
When using the Credentials property, the HttpWebRequest implementation will wait the challenge response from server before to send the 'Authorization' header value.
But this can be an issue in some cases, so you have to force Basic authentication by providing directly the Authorization header.
Example when using a REST Client library like Spring.Rest :
RestTemplate template = new RestTemplate("http://example.com");
template.RequestInterceptors.Add(new BasicSigningRequestInterceptor("login", "password"));
string result = template.GetForObject<string>(uri);
