I am trying to load web browser with the html code from the httpwebresponse by storing it in a string variable.
I created a httpwebrequest for a URL by setting cookies in it and getting a html page in a httpwebResponse.
I am trying to display it in a web browser control by saving the code in a string variable. And navigating the browser("browse.NavigateToString(string)").
But here page is not loaded properly.It is not displaying any css or images and displaying a message"You need to turn on java script in order to display the contents".
I made the web browser property (IsScriptEnabled ) true before navigation. But it is still showing the message and contents are not loaded properly.
Cookies are also not injected in to the web browser controls(session is not maintained through out the app).
Is there any solution or work around for this ??
Please refer to the below code :
To log cookies from login service :
private void PostLoginRequest()
{
string AuthServiceUri = "Service URL";
HttpWebRequest AuthReq = HttpWebRequest.Create(AuthServiceUri) as HttpWebRequest;
AuthReq.CookieContainer = new CookieContainer();
AuthReq.ContentType = "application/x-www-form-urlencoded";
AuthReq.Method = "POST";
AuthReq.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), AuthReq);
}
void GetRequestStreamCallback(IAsyncResult callbackResult)
{
HttpWebRequest Request = (HttpWebRequest)callbackResult.AsyncState;
Stream postStream = Request.EndGetRequestStream(callbackResult);
string postData = "Postdata parameters";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
postStream.Write(byteArray, 0, byteArray.Length);
postStream.Close();
myRequest.BeginGetResponse(new AsyncCallback(GetResponsetStreamCallback), Request);
}
void GetResponsetStreamCallback(IAsyncResult callbackResult)
{
try
{
HttpWebRequest callBackRequest = (HttpWebRequest)callbackResult.AsyncState;
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(callbackResult);
CookieCollection cookiecollec = new CookieCollection();
cookiecollec = response.Cookies;
App.cookieCollection = cookiecollec; //global varaiable
}
catch (Exception e)
{
MessageBox.Show(e.Message);
}
}
Another httpwebrequest with logged cookies :
private void ResponsivePostURL(string PageName, string PostURL, string PostDatas)
{
Uri ServiceUri = new Uri(PostURL); //Service URL
HttpWebRequest requestURL = HttpWebRequest.CreateServiceUri as HttpWebRequest;
requestURL.ContentType = "application/x-www-form-urlencoded";
requestURL.Method = "POST";
requestURL.CookieContainer = new CookieContainer();
requestURL.CookieContainer.Add(ServiceUri, App.cookieCollection);
requestURL.BeginGetResponse(new AsyncCallback(GetResponsetStreamCallback), requestURL);
}
void GetResponsetStreamCallback(IAsyncResult callbackResult)
{
try
{
HttpWebRequest request = (HttpWebRequest)callbackResult.AsyncState;
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(callbackResult);
// MessageBox.Show(response.Cookies.ToString());
string responseString = "<html><head></head><body>";
Stream streamResponse = response.GetResponseStream();
StreamReader reader = new StreamReader(streamResponse);
responseString = responseString + reader.ReadToEnd() + "</body></html>";
streamResponse.Close();
reader.Close();
response.Close();
this.Dispatcher.BeginInvoke(() =>
{
webBrowser.IsScriptEnabled = true;
webBrowser.NavigateToString(responseString);
});
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
When you navigate to the site and save the document, you are not getting the script, css nor image files (and any other resource for that matter) but only the static/generated HTML document as-is, which probably refer to those files using relative paths. If paths are not absolute, scripts/css/images/other resources are not found.
If you want to make it work, you need to replace relative paths with absolute paths within the HTML file.
So if you have
<script src="/scripts/cool.js"></script>
You'd replace it with
<script src="http://www.thesite.com/scripts/cool.js"></script>
(Note that this is just my best guess, not something I have actually tried out :)
void GetResponseCallback(IAsyncResult asynchronousResult)

try
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
string responseString = streamRead.ReadToEnd();
XmlReader xmlDoc = XmlReader.Create(new MemoryStream(System.Text.UTF8Encoding.UTF8.GetBytes(responseString)));
while (xmlDoc.Read())
{
if (xmlDoc.NodeType == XmlNodeType.Element)
{
if (xmlDoc.Name.Equals("ResponseCode"))
{
responseCode = xmlDoc.ReadInnerXml();
}
}
}
if (Convert.ToInt32(responseCode) == 200)
{
MessageBox.Show("Success");
}
// Close the stream object
streamResponse.Close();
streamRead.Close();
// Release the HttpWebResponse
response.Close();
}
catch (WebException e)
{
// Error treatment
// ...
}
}
in above code Messagebox.show dispalying "Invalid cross thread access".please tell me how to resolve this...
Dispatcher.BeginInvoke(() =>
MessageBox.Show("Your message")
);
Any interaction with the UI from code needs to be on the dispatcher thread, your callback from the HTTP request will not be running on this thread hence the error.
You should be able to use something like
Deployment.Current.Dispatcher.BeginInvoke(() => MessageBox.SHow("Success") );
to display the message box

I got mail. But the body messages not show in my mail. Where did I make a mistake? In my PHP code I use postData variable to get my message.
For simpler HTTP usage the classes at http://mytoolkit.codeplex.com/wikipage?title=Http might help you...
These classes help to HTTP POST files (access via $_FILES["..."]). Also there is a RawData property (byte[]) to set the data directly.
(also GZIP, own timeout, and more is supported)
I need to use POST to post a string to server and get xml response, the status code is OK but the string reponse is always ="" (0 byte). Is there any thing wrong with my code? I check the server from blackberry, works fine so the problem must come from my code:
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e)
{
s = NavigationContext.QueryString["parameter1"];
//string strConnectUrl = "http://www.contoso.com/example.aspx";
base.OnNavigatedTo(e);
// DoWebClient(s);
try
{
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(strConnectUrl);
httpWebRequest.Method = "POST";
httpWebRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
// start the asynchronous operation
httpWebRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), httpWebRequest);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
private static void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
// string XML_REQUEST = "<?xml version=\"1.0\"?><mybroker"><getConnections></mybroker>";
string post = "?&track=love";
try
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
// End the operation
Stream postStream = request.EndGetRequestStream(asynchronousResult);
// Convert the string into a byte array.
byte[] postBytes = Encoding.UTF8.GetBytes(post);
// Write to the request stream.
postStream.Write(postBytes, 0, postBytes.Length);
postStream.Close();
// Start the asynchronous operation to get the response
request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}

// End the operation

HttpStatusCode rcode = response.StatusCode;
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
//****THIS ALWAYS RETURN "" VALUE, EXPECT TO RETURN XML STRING****
string responseString = streamRead.ReadToEnd();
//Console.WriteLine(responseString);

}
*EDIT**
The code work, however the server return parameter require the Ampersand(&) which is not allow in silverlight framework I think, remove the & char server response but the result wasn't correct. I will ask a new question refer this Ampersand
Have checked your call using Fiddler. The server is returning an empty body. Your code is working correctly. The problem is server side.
The post value should be "track=love".
I tried and it worked but the response is gzip encoded.
Fiddler says that the request is good, and that the response really is blank. If it's working from Blackberry and not from WP7, could the server be doing some user agent checking and not returning anything because it doesn't recognize the WP7 user agent?
Also, it looks like you're POSTing a query string ("?&track=love") which is sort of unusual. Are you sure that's the right data to be sending in your request?
I use post to post parameter to server and get the result in string, how do I parse that result and bind it to listbox? It seems that (for some reason) I can't output the string to textblock or messagebox. For parse xml I use XDocument (which take stream in parameter)
My code following:
private static void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
string post = "track=love";
// post = HttpUtility.UrlEncode(post);
Console.WriteLine(post);
try
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
// End the operation
Stream postStream = request.EndGetRequestStream(asynchronousResult);
// Convert the string into a byte array.
byte[] postBytes = Encoding.UTF8.GetBytes(post);
// Write to the request stream.
postStream.Write(postBytes, 0, postBytes.Length);
postStream.Close();
// Start the asynchronous operation to get the response
request.BeginGetResponse(new AsyncCallback(GetResponseCallback), request);
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
private static void GetResponseCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest request = (HttpWebRequest)asynchronousResult.AsyncState;
// End the operation
HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(asynchronousResult);
HttpStatusCode rcode = response.StatusCode;
Stream streamResponse = response.GetResponseStream();
StreamReader streamRead = new StreamReader(streamResponse);
//THIS ALWAYS RETURN "" VALUE, EXPECT TO RETURN XML STRING
string str = streamRead.ReadToEnd();
//Console.WriteLine(responseString);
// Close the stream object
streamResponse.Close();
streamRead.Close();
// Release the HttpWebResponse
response.Close();
}
and I want to use XDocument to parse the data like this:
XDocument xdoc = XDocument.Load(str);
var data = from query in xdoc.Descendants("tracks").Elements("item")
select new searchResult
{
artist = (string)query.Element("artist"),
album = (string)query.Element("album"),
track = (string)query.Element("track"),
// artistA = (string)query.Element("artists").Element("artist"),
};
listBox1.ItemsSource = data;
var data1 = from query in xdoc.Descendants("artists").Elements("item")
select new searchResult
{
artistA = (string)query.Element("artist"),
};
listBox2.ItemsSource = data1;
