Internal Server Error when trying to GET windows Live Contacts

Hi all,

I am trying to use the RPS method of authentication to request information about my Windows Live contacts.

I *think* the code is okay, but I'm getting a System.Net.WebException at run time.

My (C#) code is:

(where oID is an Identity - I'm hacking about with the 'WLID Client Sample')

bool bSuccess = true;

UriBuilder uriBuilder = new UriBuilder();

uriBuilder.Scheme = "HTTPS";

uriBuilder.Path = "/" + "username@hotmail.com" + "/LiveContacts/Contacts";

uriBuilder.Host = "cumulus.services.live.com";

string uriPath = uriBuilder.Uri.AbsoluteUri;

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uriPath);

request.Method = "GET";

request.Headers.Add("Authorization", "WLID1.0 t=\"t=" + oID.ExportAuthString() + "=\"");

HttpWebResponse resp = null;

try {

resp = (HttpWebResponse)request.GetResponse();

catch(WebException e)

//Console.WriteLine(e);

textBox1.Text = e.ToString();

if(e.Status == WebExceptionStatus.ProtocolError)

resp = (HttpWebResponse)e.Response;

Thanks!!

Dear 'little miss confused":

However, by looking at your code, I suspect the problem might be on how the Authorization header is constructed. It should be of the form:

Authorization: WLID1.0 t="<RPS Token>"

But the code you have to add the authorization header:

request.Headers.Add("Authorization", "WLID1.0 t=\"t=" + oID.ExportAuthString() + "=\"");

will produce somthing like this:

Authorization: WLID1.0 t="t=<RPS Token>="

In the text above, I marked in red the stuff I think is redundant (the additional 't=' before the token and the '=' at the end) but I might be wrong because I'm not familiar with the token that the WL ID client returns. I'll investigate a little more about the WLID client to see if I'm right or not.

In the meantime, try this code to generate the authorization header and let me know if it works:

request.Headers.Add("Authorization", "WLID1.0 t=\"" + oID.ExportAuthString() + "\"" );

Also, the problem might be with how you generate the token with WL ID client. You need to get a ticket using the MBI policy. How are you getting the ticket Are you using Ws-Trust If you are, check your PolicyReference on the XML for the call to Ws-Trust is defined as ˇ°MBIˇ± as shown below.

<wspolicyReference URI = ""MBI""></wspolicyReference>

Let me know if these suggestions work!

P.S: A 500: Internal Server error typically indicates a problem with our server, not with your code so I'll check why we are returning that error.

Wow, thanks so much Federico!

That really helped, I'm now using the correct TicketAcquirer (which I should really have tried first...)

TicketAcquirer t = new TicketAcquirer();

string str = t.GetTicket();

...

request.Headers.Add("Authorization", "WLID1.0 t=\"" + str + "\"");

Using the TicketAcquirer requires managing username/password.

You can get the appropriate token from the Identity object by doing something like

string ticket = identity.GetTicket("http://live.com", "MBI", false);

request.Headers.Add("Authorization", "WLID1.0 t=\"" + ticket + "=\"");

Hi,

You can get information about this from the method from the API reference at http://msdn2.microsoft.com/en-us/library/bb404831.aspx, including a code sample.

Not sure what you mean by implementing this method.
