Good afternoon,
I'm following the example on Windows Http Server Api, found here:
http://msdn.microsoft.com/en-us/library/windows/desktop/aa364640(v=vs.85).aspx
I get my project to compile and work when I enter http://localhost:8080/test as the URl into HttpAddUrl function, and point my browser to http://localhost:8080/test on the same machine as I run the http server in the above example.
The webpage shows the response and everything works well.
here is my call to HttpAddUrl
retCode = HttpAddUrl(
hReqQueue, // Req Queue
L"http://localhost:8080/test/", // Fully qualified URL
NULL // Reserved
);
My problem, however is sending the request from another machine on the same LAN.
I tried pointing the browser to http://192.168.1.2:8080/test/ but I got a 404 error,
Then I tried changing the HttpAddUrl function to
retCode = HttpAddUrl(
hReqQueue, // Req Queue
L"http://192.168.1.2:8080/test/", // Fully qualified URL
NULL // Reserved
)
This only returned retCode = 5 (which I also cannot determine the meaning of, if somebody can help me determine the enumeration for this error variable)
Does anybody know what I am supposed to enter into the HttpAddUrl function if I want to sen an HTTP request from another machine to the local server.
Thanks,
-D
Resolved, it turns out I was not running Visual Studio with Admin privileges, error 5 was system error "Access Denied"
http://msdn.microsoft.com/en-us/library/windows/desktop/ms681382(v=vs.85).aspx
The URL of L"http://192.168.1.2:8080/test/" was corrent

I have to do load testing for a web based application. I am getting status as warning the results table. My request contains the URL and the path as /. I have passed username and password in the parameters section. Even after tried many times still it shows status as warning.
I have also tried using Proxyserver address, port, user name and password ...still no luck..
Please help me on this.
If you get a Warning status, this means that JMeter detected a response code > 399.
There can be a lot of reasons for this, examples:
Wrong URL : 404
Error : 500
To have more details on it, add a View Results Tree and inspect all tabs to see:
Request : What you are sending (headers / Cookies / body)
Response : What you are getting (headers / Cookies / body)
Then fix your HTTP request by comparing request in browser with what you have build.
Alternatively, use JMeter recording feature.
To see all ways to debug a script, have a look at this book where sample chapter explains lot of ways.
If you get warning status that means your entered URL contains https:// part which means your given URL working with HTTP protocol.
Remove https:// part from
- HTTP Request Defaults
- HTTP Request
So replace https:// part by WWW and try again
I'm working on an app using Visual Studio 2015 Cordova tools on Windows 8.1. Target is also Windows 8.1.
The app is caching HTTP GET request. So the second GET request to the same resource returns a cached response. I have tested after disabling the network adapter and I still get a response with the cached results.
I am using jsforce libray to connect to salesforce.com. I know I can add a timestamp on the url but I would like to find fix not a work around.
Any ideas?
[UPDATE]
Issue is not related to jsforce as it works well on Android. The error is specific to Windows 8.1 and cordova.
As suggested in the question, timestamping the url helps: I used:
var url = "https://api.myurl.com/" + param1 + "?" + new Date().getTime()
I wrote a simple library to add caching to REST requests for Cordova: https://github.com/glauber-md/mobile-simple-web-call#using-this-library .
The library will use a local database (sqlite) to fetch server data and cache it locally where applicable (e.g. HTTP GET requests with cache-related headers).
Once it receives a 304 Response, it will use the cached data.
To send a GET request, you'd use:
wscall.get(
'http://myserver.org/users/1234',
// (Optional) query strings
null,
function(responseData) {
// Do something when the response is successful
},
function(error) {
// Do something when an error happens
}
);
Then the data would come from remote server or local cache depending of the HTTP server response.
Maybe it will help you.
So I have been getting the infamous 404.3 error when trying to use AXAJ to access a .json file launching the site (or more of a test app hehe) through WebMatrix on localhost.
Yes, I am aware of the IIS configuration. I am on Windows 8.1(x64), so I had to even turn on MIME types functionality separately. I configured a MIME type for .json with application/javascript. Then I went and added a handler to *.json, pointed it to C:\WINDOWS\system32\inetsrv\asp.dll. I set the verbs to GET and POST (those are what I use in my ajax function). I also tried unchecking the "Invoke the handler only if request is mapped to..." to no avail.
I am using one function to send data to PHP file which writes it to the JSON file and then another to fetch data from the JSON file directly. Writing through PHP works. Fetching doesn't. I am completely at a loss, does anyone have any ideas? The code I am using to fetch the data is your bog-standard ajax:
function getDate(path, callback) {
var httpRequest = new XMLHttpRequest();
httpRequest.onreadystatechange = function() {
if (httpRequest.readyState === 4) {
if (httpRequest.status === 200) {
var data = JSON.parse(httpRequest.responseText);
if (callback) callback(data);
}
}
};
httpRequest.open('GET', path);
httpRequest.send();
}
When I host this on my server space, it works totally fine. But I want to get it to work locally for testing purposes as well.
If writing to the file works but fetching doesn't work. Then you should check for the link of the file.
The error 404 as the name refers to, is an error for the file name. There isn't any other sort of error, even the Ajax request is working fine and giving the error 404 (file not found). So the only thing that you can do is, to make sure that while fetching the data, you use the correct link.
Here can be a help, when you send the Request through Ajax, there is a Network tab in your Browser's console. Open it, and look for the request. It would in red color denoting an error and click it. You'll see that the link you're providing isn't valid.
Look for the errors in the File Link then and update it.
The lengths I go to, to clean up my profile...
When you require a JSON format, or any file for that matter you have to specify in your request what data type you need, IIS will not make any assumptions. So
xhr.setRequestProperty('Content-Type', 'application/json');
is something one must not forget. I set also the X-Requested-With header. Note that to reproduce this issue I used IIS that is installed on Windows 10 Pro, so not exactly the same system (3 years later - holy crap!).
I have an RP for which I've built a login page using the Json feed from ACS. The IP images are linked to the .LoginUrl attribute of the feed and when I click on one of the images it correctly jumps to that IP's page.
Entering my credentials, however, I'm redirected to a page on the appfabriclabs.com site with the following error:
HTTP Error Code: 400
Message: ACS50000: There was an error issuing a token.
ACS50011: The RP ReplyTo address is missing. Either the RP ReplyToAddresses
are not configured or an invalid wreply 'https://www.skillscore.it/' was received
in the sign-in request.
the RP is configured in the App Labs site with a returnUrl of:
https://www.skillscore.it/Home/FederationResult
and in looking at the wreply parameter in the feed, I see:
https%3a%2f%2fskillscore.accesscontrol.appfabriclabs.com%3a443%2fv2%2fwsfederation
According to some SO articles like [this one] the return url of the app should be a prefix of the wreply parameter - which is clearly not the case here.
so... what have I done wrong now?
e
p.s. one interesting bit of info: in the Application Integration page of ACS there is a link to the ACS-hosted login page. the link used there seems to differ from the one I'm given in the feed; in particular, the ACS-hosted page uses a wctx of:
pr%3dwsfederation%26rm%3dhttps%253a%252f%252fwww.skillscore.it%252f
whereas the feed gives me:
pr%3dwsfederation%26rm%3dhttps%253a%252f%252fwww.skillscore.it%252f%26ry%3dhttps%253a%252f%252fwww.skillscore.it%252f
so I don't know what that's worth but maybe it's a clue to what's wrong.
* update *
decoded, that last string is:
pr=wsfederation
&rm=https%3a%2f%2fwww.skillscore.it%2f
&ry=https%3a%2f%2fwww.skillscore.it%2f
which clearly shows the Json feed is providing an ry that is not present in the ACS-hosted page... meaning anything to anyone?
ok. my bad. apparently, when I was fetching the Json feed, the URL I used did not have the reply_to set correctly.
I am getting this Error
NETWORK_ERROR: XMLHttpRequest Exception 101
when trying to get XML content from one site.
Here is my code:
var xmlhttp;
if(window.XMLHttpRequest) {
xmlhttp = new XMLHttpRequest();
}
if (xmlhttp==null) {
alert ("Your browser does not support XMLHTTP!");
return;
}
xmlhttp.onReadyStateChange=function() {
if(xmlhttp.readyState==4) {
var value =xmlhttp.responseXML;
alert(value);
}
}
xmlhttp.open("GET",url,false);
xmlhttp.send();
//alert(xmlhttp.responseXML);
}
xmlhttp.open("GET",url,false);
xmlhttp.send(null);
Does any one have a solution?
If the url you provide is located externally to your server, and the server has not allowed you to send requests, you have permission problems. You cannot access data from another server with a XMLHttpRequest, without the server explicitly allowing you to do so.
Update: Realizing this is now visible as an answer on Google, I tried to find some documentation on this error. That was surprisingly hard.
This article though, has some background info and steps to resolve. Specifically, it mentions this error here:
As long as the server is configured to allow requests from your web application's origin, XMLHttpRequest will work. Otherwise, an INVALID_ACCESS_ERR exception is thrown
An interpretation of INVALID_ACCESS_ERR seems to be what we're looking at here.
To solve this, the server that receives the request, must be configured to allow the origin. This is described in more details at Mozilla.
The restriction that you cannot access data from another server with a XMLHttpRequest can apply even if the url just implies a remote server.
So:
url = "http://www.myserver.com/webpage.html"
may fail,
but:
url = "/webpage.html"
succeed - even if the request is being made from www.myserver.com
Request aborted because it was cached or previously requested? It seems the XMLHttpRequest Exception 101 error can be thrown for several reasons. I've found that it occurs when I send an XMLHttpRequest with the same URL more than one time. (Changing the URL by appending a cache defeating nonsense string to the end of the URL allows the request to be repeated. -- I wasn't intending to repeat the request, but events in the program caused it to happen and resulted in this exception).
Not returning the correct responseText or responseXML in the event of a repeated request is a bug (probably webKit).
When this exception occurred, I did get an onload event with readyState==4 and the request object state=0 and responseText=="" and responseXML==null. This was a cross domain request, which the server permits.
This was on an Android 2.3.5 system which uses webKit/533.1
Anyone have documentation on what the exception is supposed to mean?
Something like this happened with me when I returned incorrect XML (I put an attribute in the root node). In case this helps anyone.
xmlhttp.open("GET",url, true);
set the async part to true
I found a very nice article with 2 diferent solutions.
The first one implementing jQuery and JSONP, explaining how simple it is.
The second approach, it's redirecting trough a PHP call. Very simple and very nice.
http://mayten.com.ar/blog/42-ajax-cross-domain
Another modern method of solving this problem is Cross Origin Ressource Sharing.
HTML5 offers this feature. You can "wrap" your XMLhttp request in this CORS_request and
if the target browser supports this feature, you can use it and wont have no problems.
EDIT:
Additionaly i have to add that there are many reasons which can cause this Issue.
Not only a Cross Domain Restriction but also simply wrong Settings in your WEB.CONFIG of your Webservice.
Example IIS(.NET):
To enable HTTP access from external sources ( in my case a compiled Phonegap app with CORS request ) you have to add this to your WEB.CONFIG
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost"/>
</protocols>
</webServices>
Another scenario:
I got two webservices running... One on Port 80 and one on Port 90. This also gave me an XML HTTP Request Error. I even dont know why :). Nevertheless i think this can help many not well experienced readers.
