Jquery .ajax fails when basic auth username has @ symbol (ios / cordova)

Question

I have a phonegap app w/ jQuery 1.9.1 Worked great as long as the username doesn't have '@' symbol in it (like in email addresses). It only fails on iOS.

I suspect it's probably not urlencoding the @ sign or something.

• iPhone, it never hits any callbacks (done, fail or always), Wireshark shows request doesn't get to the server.
• Chrome Desktop: works fine.

• Android, works fine.

   $.ajax({
          url: "https://" + this.hostname + "/alertusmw/services/rest/" + endPoint,
          type: method,
          dataType: 'json',
          contentType: 'application/com.alertus-v1.0+json',
          cache:false,
          username: this.username,
          password: this.password,
          beforeSend: function (xhr) {
              xhr.setRequestHeader("Authorization",
                  "Basic " + $.base64.encode(this.username + ":" + this.password));
          },
          data: options.data
      }).done(function(response) {
          console.log("DONE: " + method + ' completed: ');
          console.log(response);
          options.success( response );
      })
      .fail(function(jqXHR, textStatus, errorThrown) {
          console.log("FAIL: " + method + " FAILED: " + textStatus + "\n" + "ERROR THROWN: " + errorThrown);
          console.log("jqXHR thing: ", jqXHR);
          options.error(jqXHR,textStatus,errorThrown);
      })
      .always(function(jqXHR, textStatus, errorThrown) {
          console.log("In the always", jqXHR, textStatus, errorThrown);
      });
  

  • Verified the base64 header is identical on iphone and chrome desktop.
  • It's not an ssl cert issue.
  • It's not a cors issue
  • It's not an invalid user/pass

Again works perfectly if username doesn't have an '@'

The reason I suspect it's something with url encoding is if it was posting it as: https://user@domain:[email protected], the browser wouldn't probably include the domain:password part as the host (since the first @ is what separates user:pass from the domain...

Here's what clued me in to this:

^-- I thought the entire point of base64 encoding was exactly to avoid special characters causing issues... so I thought that maybe this was chrome being helpful...

I would bet the problem is not using a contentType : "application/x-www-form-urlencoded".

Anyway, you should definitely debug your Webview against a real device, to look for xhr errors on the Safari console. If you are not familiar with Safari remote debugging, it's easy:

• in your iPhone/iPad, go to Settings -> Safari -> Advanced => Enable Web Inspector.
• connect to MacOSX via cable, and select your app from the "Develop" menu of Safari in your desktop
• Now check any errors regarding your request, or better yet, debug the code and callbacks step by step.
