Question

Ok, so I can’t seem to find decent Windows Azure examples. I have a simple hello world application that’s based on this tutorial. I want to have custom output instead of JSON or XML. So I created my interface like:

[ServiceContract]
public interface IService
{
    [OperationContract]
    [WebInvoke(UriTemplate = "session/create", Method = "POST")]
    string createSession();
}

public class MyService : IService
{
    public string createSession()
    {
        // get access to POST data here: user, pass
        string sessionid = Session.Create(user, pass);
        return "sessionid=" + sessionid;
    }
}

For the life of me, I can’t seem to figure out how to access the POST data. Please help. Thanks!

Answer 1

If you have an HttpContext there may be a Request object that would have the form data. I’m basing part of this off the ASP.Net tag on this question, so if that is incorrect then there may be the need to handle this another way but it looks a lot like a web service to my mind.

EDIT: HttpRequest is the class that has the Form property that should be where the POST data is stored if this is an HTTP request. This is part of System.Web so it should be ready to be used pretty easily, as I recall.

Sample code showing the Request.Form property:

int loop1;
NameValueCollection coll;

//Load Form variables into NameValueCollection variable.
coll=Request.Form;
// Get names of all forms into a string array.
String[] arr1 = coll.AllKeys;
for (loop1 = 0; loop1 < arr1.Length; loop1++) 
{
    Response.Write("Form: " + arr1[loop1] + "<br>");
}

This presumed there was an HttpRequest instance around.

WCF Simplified Part 4: Comparing the Request/Reply and One-Way Patterns passes in a parameter so that your “createSession” method would have to take in those strings it would appear. I’m used to the ASP.Net world where there are some built-in objects like Request, Response, Server, Application and Session.

Yes, if you did try changing the method signature as there are ways to pass in parameters in that last example I linked though I don’t know if that would work in your case or not.
