Http Post for Windows Phone 8

Http Post for Windows Phone 8

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);
}

Http Get Request in windows phone 8.1

hope the below helps

try{

 var client = new HttpClient();

    var uri = new Uri("your URI"); 

    //Call. Get response by Async
    var Response = await client.GetAsync(uri);

    //Result & Code
    var statusCode = Response.StatusCode;

    //If Response is not Http 200 
    //then EnsureSuccessStatusCode will throw an exception
    Response.EnsureSuccessStatusCode();

    //Read the content of the response.
    //In here expected response is a string.
    //Accroding to Response you can change the Reading method.
    //like ReadAsStreamAsync etc..
    var ResponseText = await Response.Content.ReadAsStringAsync();
}

catch(Exception ex)
{
    //...
}

Http post call in windows phone 8

This is a sample code I used in my project. Modify according to your needs

HttpWebRequest req = (HttpWebRequest)WebRequest.Create("url to submit to");
req.Method = "POST";

//Add a Header something like this
//req.Headers["SOAPAction"] = "http://asp.net/ApplicationServices/v200/AuthenticationService/Login";

req.ContentType = "text/xml; charset=utf-8";

//req.UserAgent = "PHP-SOAP/5.2.6";

string xmlData = @"<?xml version=""1.0"" encoding=""UTF-8""?>Your xml data";

// Convert the string into a byte array.
byte[] byteArray = Encoding.UTF8.GetBytes(xmlData);
req.Headers[HttpRequestHeader.ContentLength] = byteArray.Length.ToString();

req.BeginGetRequestStream(ar =>
{
    using (var requestStream = req.EndGetRequestStream(ar))
    {
        // Write the body of your request here
        requestStream.Write(byteArray, 0, xmlData.Length);
    }

    req.BeginGetResponse(a =>
    {
        try
        {
            var response = req.EndGetResponse(a);
            var responseStream = response.GetResponseStream();

            using (var streamRead = new StreamReader(responseStream))
            {
                // Parse the response message here
                string responseString = streamRead.ReadToEnd();
                //If response is also XML document, parse it like this
                XDocument xdoc = XDocument.Parse(responseString);
                string result = xdoc.Root.Value;

                if (result == "true")
                {
                    //Do something here
                }
                else
                    Dispatcher.BeginInvoke(() =>
                    {
                        //result failed
                        MessageBox.Show("Some error msg");
                    });
            }
        }
        catch (Exception ex)
        {
            Dispatcher.BeginInvoke(() =>
            {
                //if any unexpected exception occurs, show the exception message
                MessageBox.Show(ex.Message);
            });
        }

    }, null);

}, null);
