How to Call Rest WCF service using HTTPWebRequest or Webclient?

Question

Hi i Have created WCF service , Service contract and Data contract is pasted below

[ServiceContract]
public interface IRestWithXML
{
    [OperationContract]
    [WebInvoke(Method = "Post", UriTemplate = "DoWork", RequestFormat=                WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
    string DoWork(Test objtest);

    [OperationContract]
    [WebInvoke(Method = "Post", UriTemplate = "Method?test={strtest}", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
    string Method(Test objtest,string strtest);

}          

[DataContract]
public class Test
{
    [DataMember]
    public string id { get; set; }
}

How should i test these services in .NET . I can able to test the methods by changing method "Post" to "GET" .

But I have to test these services using "Post" . Please guide me

thanks in advance !!!!

The fact that you're using WCF and the WebInvoke attribute doesn't mean you can search for the more generic terms.

You're just looking for a way to "test POST to REST service", and if you type that into your favourite web search engine, the following hits may turn up:

Just set the Method to "POST". http://msdn.microsoft.com/en-US/library/system.net.httpwebrequest.method.aspx

var myWebRequest = new HTTPWebRequest();
myWebRequest.Method = "POST"

To test a POST request, you have to change some things in your code :

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "DoWork", RequestFormat=WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
string DoWork(Stream objtest);

You set the parameter to Stream.

In the implementation of DoWork(Stream objtest) :

public string DoWork(Stream objtest)
{
     StreamReader sr = new StreamReader(stream);
     string s = sr.ReadToEnd();
     sr.Dispose();
     NameValueCollection collection = System.Web.HttpUtility.ParseQueryString(s);
     return collection.ToString();
}

To test you request, you have to use a REST Client (Fiddler ?) and the content of you body will be in the collection.

If you want to create the request in C#:

string body ="&key1=value1&key2=value2";
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";

using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
    writer.Write(body);
}

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Thanks for the reply ..I have tried but I'm getting Remote Server returned error .Method Not Allowed Error — Parthi, Mar 08 '13 at 12:14
