(Firefox OS Graveyard :: General, defect)

Description

[Jose Manuel Cantera]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.4 Safari/537.1

Steps to reproduce:

var imgSrc = 'https://graph.facebook.com/picture/100001127136581?type=square';
      
      var xhr = new XMLHttpRequest({mozSystem: true});
      xhr.open('GET', imgSrc, true);
      xhr.responseType = 'blob';
      xhr.timeout = 6000;
      xhr.onload = function(e) {
        window.console.log('Success CB invoked for img uid',uid);
        if (xhr.status === 200 || xhr.status === 0) {
          window.console.log('200 ok for uid',uid);
          var mblob = e.target.response;
          var reader = new FileReader();
          reader.onload = function(e) {
            cb(e.target.result);
          }

          reader.readAsDataURL(mblob);
        }
      }

      xhr.ontimeout = function(e) {
        window.console.log('Timeout!!! while retrieving img for uid',uid);
      }

      xhr.onerror = function(e) {
        window.console.error(e);
        cb('');
      }

      xhr.send();
    }


Actual results:

Error callback is invoked


Expected results:

onload callback with success

The URL referenced is a HTTPS URL which actually performs a redirection ... just in case it helps to solve the bug

Are you sure HTTPS is the reason for the bug (as suggested in the bug summary) rather than the redirection?

Jose, is this running in an app with the "systemXHR" permission?

Yes, it was but this bug was open neary two years ago, I believe we can close it
