I\'ve been dying for about 6 hours trying to figure out how to make a regular POST request in WP7 , I tried the answers of similar questions posted here and on many other places
I use the following class for making POST requests with WP7:
public class PostMultiPartFormData
{
private Dictionary Parameters;
private Encoding ENCODING = Encoding.UTF8;
private string BOUNDARY = "-----------------------------wp7postrequest";
public event EventHandler PostComplete;
public void Post(string postbackURL,
Dictionary parameters)
{
Parameters = parameters;
Uri url = null;
url = new Uri(postbackURL);
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";
request.ContentType = "multipart/form-data; boundary=" + BOUNDARY;
request.BeginGetRequestStream(new AsyncCallback(SendStatusUpdate), request);
}
private void SendStatusUpdate(IAsyncResult ar)
{
HttpWebRequest request = (HttpWebRequest)ar.AsyncState;
Stream stream = request.EndGetRequestStream(ar);
byte[] byteArray = GetMultipartFormData(Parameters, BOUNDARY);
stream.Write(byteArray, 0, byteArray.Length);
stream.Close();
stream.Dispose();
request.BeginGetResponse(new AsyncCallback(StatusUpdateCompleted), request);
}
private byte[] GetMultipartFormData(Dictionary postParameters, string boundary)
{
Stream formDataStream = new System.IO.MemoryStream();
foreach (var param in postParameters)
{
if (param.Value is byte[])
{
byte[] fileData = param.Value as byte[];
string header = string.Format("--{0}\r\nContent-Disposition: form-data; name=\"{1}\"; filename=\"{2}.jpg\";\r\nContent-Type: application/octet-stream\r\n\r\n", boundary, param.Key, param.Key);
formDataStream.Write(ENCODING.GetBytes(header), 0, header.Length);
formDataStream.Write(fileData, 0, fileData.Length);
}
else
{
string postData = string.Format("--{0}\r\nContent-Disposition: form-data; name=\"{1}\"\r\n\r\n{2}\r\n", boundary, param.Key, param.Value);
byte[] b = ENCODING.GetBytes(postData);
foreach (var item in b)
{
formDataStream.WriteByte(item);
}
}
}
string footer = "\r\n--" + boundary + "--\r\n";
byte[] footerbytes = ENCODING.GetBytes(footer);
formDataStream.Write(footerbytes, 0, footerbytes.Length);
formDataStream.Position = 0;
byte[] formData = new byte[formDataStream.Length];
formDataStream.Read(formData, 0, formData.Length);
formDataStream.Flush();
formDataStream.Close();
return formData;
}
private void StatusUpdateCompleted(IAsyncResult ar)
{
if (PostComplete != null)
{
PostComplete(ar, null);
}
}
}
Example:
PostMultiPartFormData postRequest = new PostMultiPartFormData();
postRequest.PostComplete += new EventHandler( (sender, e) =>
{
IAsyncResult ar = ((IAsyncResult)sender);
using (WebResponse resp = ((HttpWebRequest)ar.AsyncState).EndGetResponse(ar))
{
using (StreamReader sr = new StreamReader(resp.GetResponseStream()))
{
string responseString = sr.ReadToEnd();
this.Dispatcher.BeginInvoke(() =>
{
textBlock.Text = responseString;
});
}
}
});
postRequest.Post("http://localhost:50624/SSLProxy.ashx",
new Dictionary() { { "param1", "value1" } });
This should work... If it doesn't let me know! :-)
