Question

I already have an existing application implemented using java in app engine….now i want to connect this servlet from c# forms program ?,…this is the tried out code for request

HttpWebRequest authRequest = (HttpWebRequest)HttpWebRequest.Create(googleLoginUrl);
byte[] buffer = Encoding.ASCII.GetBytes(postData);
authRequest.ContentLength = buffer.Length;
 Stream postDataStr=authRequest.GetRequestStream();
postDataStr.Write(buffer, 0, buffer.Length);
postDataStr.Close();

now it is connected to the GSE(Google Servlet Engine)…i want a response for this….how to implement that?

Answer 1

You just need to read the response:

HttpWebResponse response = (HttpWebResponse)authRequest.GetResponse ();
Console.WriteLine ("Content length is {0}", response.ContentLength);
Console.WriteLine ("Content type is {0}", response.ContentType);
string raw_html = (new StreamReader(response.GetResponseStream()).ReadToEnd();

You can see further examples from: http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.getresponse.aspx

Note: I believe since you’re posting data you’ll also have to set your authRequest as a POST via:

authRequest.Method = "POST";
