c# - Http Post for Windows Phone 8

Question

I am new to C# so I was wondering if someone can help me out on this. I am trying to send HttpPost from Windows Phone 8 to the server. I found two examples that I would like to combine.

The first one is an example of sending Http Post (http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.begingetrequeststream.aspx). The problem with this one is that it is not support by Windows Phone 8.

The second example is using the BeginGetResponse (http://msdn.microsoft.com/en-us/library/windowsphone/develop/system.net.httpwebrequest(v=vs.105).aspx). This supports windows phone 8.

I need to convert the second example into a BeginGetRequestStream() like the first example. I will try to figure out this myself, but I am posting online if someone already knows how to do this. I am sure this will be helpful for other WP8 developers.

Update I am now trying to get response from the server. I have started a new question. Please follow this link (Http Post Get Response Error for Windows Phone 8)

Answer 1

I am also currently working on a Windows Phone 8 project and here is how I am posting to a server. Windows Phone 8 sort of has limited access to the full .NET capabilities and most guide I read say you need to be using the async versions of all the functions.

// server to POST to
string url = "myserver.com/path/to/my/post";

// HTTP web request
var httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.ContentType = "text/plain; charset=utf-8";
httpWebRequest.Method = "POST";

// Write the request Asynchronously 
using (var stream = await Task.Factory.FromAsync<Stream>(httpWebRequest.BeginGetRequestStream,          
                                                         httpWebRequest.EndGetRequestStream, null))
{
   //create some json string
   string json = "{ "my" : "json" }";

   // convert json to byte array
   byte[] jsonAsBytes = Encoding.UTF8.GetBytes(json);

   // Write the bytes to the stream
   await stream.WriteAsync(jsonAsBytes, 0, jsonAsBytes.Length);
}
