I have been struggling to get my jquery call to a webmethod to work.

  • 0

I have been struggling to get my jquery call to a webmethod to work. I am being bounced by the server with a “401 Unauthorized” response. I must have an incorrect setting in the web.config or somewhere else that would be preventing a successful call.

Your insight is appreciated!

Call to js function the invokes the jquery call

button.OnClickAction = "PageMethod('TestWithParams', ['a', 'value', 'b', 2], 'AjaxSucceeded', 'AjaxFailed'); return false;";

JavaScript function that makes the jquery call

function PageMethod(fn, paramArray, successFn, errorFn) {
var pagePath = window.location.pathname;
var urlPath = pagePath + "/" + fn;

//Create list of parameters in the form:  
//{"paramName1":"paramValue1","paramName2":"paramValue2"}  
var paramList = '';
if (paramArray.length > 0) {
    for (var i = 0; i < paramArray.length; i += 2) {
        if (paramList.length > 0) paramList += ',';
        paramList += '"' + paramArray[i] + '":"' + paramArray[i + 1] + '"';
    }
}
paramList = '{' + paramList + '}';

//Call the page method
$.ajax({
    type: "POST",
    url: pagePath + "/" + fn,
    contentType: "application/json; charset=utf-8",
    data: paramList,
    timeout: 10000,
    dataType: "json",
    success: function(result) { alert('Overjoyed'); },
    error: function(result) { alert('No joy'); }
});
}

Web method in page

    public partial class WebLayout : System.Web.UI.Page
{

    [WebMethod()]
    public static int TestNoParams()
    {
        return 1;
    }

    [WebMethod()]
    public static string TestWithParams(string a, int b)
    {
        return a + b.ToString();
    }
...

Response as seen in Firebug console

json: {"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"}

and 

"NetworkError: 401 Unauthorized - http://localhost/Care-Provider-Home/Profile/Personal-Profile.aspx/TestWithParams" TestWithParams

I have looked at and read the usual sites on the subject (Encosia, et al), but to avail. Either I am missing a critical piece, or there are some subtleties in the security parameters of my environment that preventing a call.

Here are some other potentially useful tidbits that may impact your diagnosis:

  • Webmethods in codebehind
  • Using Sitecore CMS (Does not seem to intefere, never know)
  • IIS7
  • .NET 3.5
  • jQuery 1.3.2

I look forward to your insights and direction–thank you!

    Yes, it did get working! Since Sitecore CMS does perform URL rewriting to generate friendly URLs (it assembles the pages in layers, dynamically, similar to Master Page concept), it occurred to me that it may be causing some problem the initially caused the 401 error. I verified this by creating a separate project with a single ASPX–and with some work I was able call the web methods and get values using the jquery. I then created nearly identical ASPX in my web root, but told Sitecore to ignore it when a request is made to it (IgnoreUrlPrefixes in the web.config), after some work I was able also get it to work successfully! Thanks for your help.
