Question

I would like to login to the webpage Android Market using C#. I spent the whole day reading about HTTP requests and POST data, but nothing seems to work. What I can do is read the webpage that holds the google login form. But reading the page AFTER the login seems impossible…

Can anyone give me a hint on how to do this?

BTW: The code I’ve tried is shown below:

string mail = "[e-mail]";
string pw = "XXXXXXXXXX";

// Create a request using a URL that can receive a post. 
WebRequest request = WebRequest.Create (@"https://market.android.com/publish");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = String.Format ("Email={0}&Passwd={1}&signIn=Sign+in", mail, pw);
byte[] byteArray = Encoding.UTF8.GetBytes (postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams.
reader.Close ();
dataStream.Close ();
response.Close ();

What I usually do: get live http headers for firefox and you can record the request your browser sends. Then simply repeat that in code.

for example, the android marketplace does it pretty different from your code.

it actually posts to: https://accounts.google.com/ServiceLoginAuth

And posts the data continue=https%3A%2F%2Fmarket.android.com%2Fpublish%2FHome&followup=https%3A%2F%2Fmarket.android.com%2Fpublish%2FHome&service=androiddeveloper&nui=1&dsh=&GALX=&pstMsg=1&dnConn=&timeStmp=&secTok=&Email=Passwd=&signIn=
