Cross Domain Support broken in jquery 1.5

[shreddd]

Following up on the following posting in the forum: ​http://forum.jquery.com/topic/is-cross-domain-support-broken-in-jquery-1-5

When I try to make a cross domain request (using CORS), I cannot make requests that need the "withCredentials" flag

The following code seems to ignore the xhr.withCredentials flag.

    $.ajax({
      url:  cross_domain_url,
      beforeSend: function(xhr) {
        xhr.withCredentials=true;
      },
      success: function(res, textStatus, xhr) {
        alert(res);
      }
    });

This works with jquery-1.4, but the success handler is never triggered in jquery 1.5. I am using firefox 3.6. Thanks -S

Thanks for taking the time to contribute to the jQuery project! Please provide a reduced jsFiddle test case to help us assess your ticket!

Additionally, test against the jQuery 0 GIT version to ensure the issue still exists.

I can confirm this bug. The withCredentials property is put on the jXHR object and, as such, is not propagated to the native xhr (because the native xhr is completely hidden now).

I think the best course of action (seeing as there may be other fields settable on xhr in the future) is to provide a new option (something like xhrProperties) that would contain a map of properties to set on the xhr after creation.

This would look like this:

$.ajax({
   xhrProperties: {
      withCredential: true
   }
});

Only workaround as of now is to redefine the xhr method in the settings like this:

$.ajax({
   xhr: function() {
      var xhr = $.ajaxSettings.xhr();
      xhr.withCredential = true;
      return xhr;
   }
});

If there is no objection, I'll work on adding this feature into core since it's obviously a regression.

Fixes #8146 by introducing the xhrFields option with is a map of fieldName/fieldValue to set on the native xhr. Can be used to set withCredentials to true for cross-domain requests if needed.

shreddd, can you confirm your issue is solved if you set the xhrFields option, using git0?

Sample code:

$.ajax({
   xhrFields: {
      withCredentials: true
   }
});

git0: ​http://code.jquery.com/jquery-git.js

Fix confirmed to be working in Firefox.

Fix does not work in Chrome: Line 7211 throws an exception:

xhr[ i ] = s.xhrFields[ i ];

Error: INVALID_STATE_ERR: DOM Exception 11

Got it: ​http://code.google.com/p/v8/issues/detail?id=789

Should be set after the xhr has been opened. On it.

Fixes #8146. Custom fields in xhrFields are now set after the XMLHttpRequest object has been opened.

shreddd: should be all good now :)

Tested on Firefox and Chrome. Appears to be working. Thanks for the excellent response time on the bug fix.

Docs were updated during the 1.5.1 sprint, but I've added an example and further notes about 1.5 compatibility with the flag here: ​http://api.jquery.com/jQuery.ajax/

It seems that this issue is still not solved. The success function will not get executed.

Here is my code:

jQuery.ajax({

type: 'POST', url: $this.attr('action'), data: $this.serialize(), success: function(data) {

console.log("Success"); alert(data); if(data.redirect){

window.location.href=response.redirect;

}

}, xhrFields: {

withCredentials: true

}

});

Hm, that’s strange, the fail handler does something. But why fail?

jQuery.ajax({

type: 'POST', url: $this.attr('action'), data: $this.serialize(), xhrFields: {

withCredentials: true },

success: function(data) {

console.log("Success"); alert(data); if(data.redirect){

window.location.href=response.redirect;

}

}

}).fail(function() {

alert('SAdf'); });
