Building a javascript client for the TFS SOAP webservice

Question

I am trying to build a javascript client that gets information about active projects on a TFS.

Since TFS has SOAP endpoints I was thinking of using wsdl2js ( http://cxf.apache.org/docs/tools.html ) to generate a local proxy and then call the functions that i need on that proxy (like list projects, etc).

Here's my js code:

    function showresponse(response)
    {
        alert("rasp");
    }

    function showerror(error)
    {
        alert('error');
    }


    var test=new ClassificationSoap();
    test.url="http://192.168.48.130:8080/Services/v1.0/CommonStructureService.asmx";
    test.ListAllProjects(showresponse,showerror);

However, neither of the response functions are called.

According to CommonStructureService.asmx here's how the request should look:

POST /Services/v1.0/CommonStructureService.asmx HTTP/1.1
Host: 192.168.48.130
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://schemas.microsoft.com/TeamFoundation/2005/06/Services/Classification/03/ListAllProjects"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <ListAllProjects xmlns="http://schemas.microsoft.com/TeamFoundation/2005/06/Services/Classification/03" />
  </soap:Body>
</soap:Envelope>

I fired fiddler, and here's how my raw request looks:

OPTIONS http://192.168.48.130:8080/Services/v1.0/CommonStructureService.asmx HTTP/1.1
Host: 192.168.48.130:8080
Connection: keep-alive
Cache-Control: max-age=0
Access-Control-Request-Method: POST
Origin: null
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.122 Safari/534.30
Access-Control-Request-Headers: MessageType, SOAPAction, Content-Type
Accept: */*
Accept-Encoding: gzip,deflate,sdch
Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

As you can see, there is no xml sent.

Here's the raw response:

HTTP/1.1 401 Unauthorized
Content-Length: 1656
Content-Type: text/html
Server: Microsoft-IIS/6.0
WWW-Authenticate: NTLM

<ul>
<li>Contact the Web site administrator if you believe you should be able to view this directory or page.</li>
<li>Click the <a href="javascript:location.reload()">Refresh</a> button to try again with different credentials.</li>
</ul>

<li>Go to <a href="http://go.microsoft.com/fwlink/?linkid=8180">Microsoft Product Support Services</a> and perform a title search for the words <b>HTTP</b> and <b>401</b>.</li>
<li>Open <b>IIS Help</b>, which is accessible in IIS Manager (inetmgr),
 and search for topics titled <b>About Security</b>, <b>Authentication</b>, and <b>About Custom Error Messages</b>.</li>
</ul>

</TD></TR></TABLE></BODY></HTML>

So basically it says it needs authentication.

Why isn't the showerror function called? How can my client know how to ask user for credentials?

Also, how does authentication work?

I know I need to send an authorization header that contains "user:pass" encoded with base64, but I can't find any reference to this in the generated Classification.js

Thanks

You'll note that your first request was an OPTIONS request, not a POST. Are you sending your request to a cross-origin server using XMLHTTPRequest? If so, the server needs to be configured, via CORS, to return an Access-Control-Allow-Origin directive in response to that pre-flight OPTIONS request.
