Why does not my OData jQuery Dynamic CRM On-Line query work?

advertisements

I have a web page that needs to obtain information from Dynamics CRM2011 on-line using jQuery. As a test, I've just tried to retrieve all of the accounts from a test system. I've used some code that I've tested within the CRM product, and it works.

When I try to run the same jQuery code in a separate web page that is not on the CRM domain it doesn't work (no transport) so I added the $.support.cors = true line to allow cross-site scripting. Now when it runs it pops up a dialog box asking for credentials. However, when I enter my credentials for CRM on-line, it doesn't accept them. After three attempts I get the error, "unauthorized".

Can anyone help?

Here's the code:

$(document).ready(function()
{

var request = "https://myorganisation.crm4.dynamics.com/XRMServices/2011/OrganizationData.svc/AccountSet";
$.support.cors = true;

$.ajax({
    type: "GET",
    contentType: "application/json; charset=utf-8",
    datatype: "json",
    url: request,
    async: false,
    beforeSend:
        function (XMLHttpRequest)
        {
            XMLHttpRequest.setRequestHeader("Accept", "application/json");
        },
    success:
        function (data, textStatus, XmlHttpRequest)
        {
            var result = data.d.results[0];
            alert('Success');
            alert(result);
            alert(result.Name);
        },
    error:
        function (XmlHttpRequest, textStatus, errorThrown)
        {
            alert(textStatus);
            alert(errorThrown);
        }
    });
});

The oData endpoint doesn't support cross site requests. It is designed to only support authentication from within the CRM application using either Silverlight or JavaScript Web Resources.

Take a look at this MSDN article for more info.
