Get Response from HttpWebRequest on Windows Phone 8

Question

I'm trying to do a WebRequest to a site from a Windows Phone Application. But is vry important for me to also get the response from the server. Here is my code:

 Uri requestUri = new Uri(string.Format("http://localhost:8099/hello/{0}", metodo)); HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(requestUri); httpWebRequest.ContentType = "application/xml; charset=utf-8"; httpWebRequest.Method = "POST"; using (var stream = await Task.Factory.FromAsync<Stream>(httpWebRequest.BeginGetRequestStream, httpWebRequest.EndGetRequestStream, null)) { string xml = "<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">Ahri</string>"; byte[] xmlAsBytes = Encoding.UTF8.GetBytes(xml); await stream.WriteAsync(xmlAsBytes, 0, xmlAsBytes.Length); }

Unfortunatelly, I have no idea of how I could get the response from the server. Does anyone have an idea?

Thanks in advance.

Thanks to @max I found the solution and wanted to share it above. Here is how my code looks like:

 string xml = "<string xmlns=\"http://schemas.microsoft.com/2003/10/Serialization/\">Claor</string>"; Uri requestUri = new Uri(string.Format("http://localhost:8099/hello/{0}", metodo)); string responseFromServer = "no response"; HttpWebRequest httpWebRequest = HttpWebRequest.Create(requestUri) as HttpWebRequest; httpWebRequest.ContentType = "application/xml; charset=utf-8"; httpWebRequest.Method = "POST"; using (Stream requestStream = await httpWebRequest.GetRequestStreamAsync()) { byte[] xmlAsBytes = Encoding.UTF8.GetBytes(xml); await requestStream.WriteAsync(xmlAsBytes, 0, xmlAsBytes.Length); } WebResponse webResponse = await httpWebRequest.GetResponseAsync(); using (var reader = new StreamReader(webResponse.GetResponseStream())) { responseFromServer = reader.ReadToEnd(); }

I hope it will help someone in the future.

We have no idea what your service does, how it looks like. How do you expect us to answer it? — EZI

I suggest you should use HttpClient instead HttpWebRequest. for that you might need to add an extra Nu-Get Package by Microsoft. It will make your web call easy. For further help, brief your question little more.. — Keval Langalia

This is very common question for people new in windows phone app development. There are several sites which gives tutorials for the same but I would want to give small answer here.

In windows phone 8 xaml/runtime you can do it by using HttpWebRequest or a WebClient.

Basically WebClient is a wraper around HttpWebRequest.

If you have a small request to make then user HttpWebRequest. It goes like this

HttpWebRequest request = HttpWebRequest.Create(requestURI) as HttpWebRequest; WebResponse response = await request.GetResponseAsync(); using (var reader = new StreamReader(response.GetResponseStream())) { string responseContent = reader.ReadToEnd(); // Do anything with you content. Convert it to xml, json or anything. }

Although this is a get request and i see that you want to do a post request, you have to modify a few steps to achieve that.

Visit this place for post request.

Thanks @max. Your answer is perfect and solved my problem. You are a life savior!
