angularjs - Angular HTTP: Status -1 and CORS

Question

In our angular application sometimes we get http status -1 returned to us. The status -1 happens on a popup that is closed, so the user isn't affected by it, just our logs.

I attempted to handle it by doing

      switch (response.status) {
        case 0:
          break;
        case -1:
          break;
        case 401:
          localStorageService.clearAll();
          redirectToUrlAfterLogin.url = $location.path();
          $location.path('/login');

Which was suggested in AngularJS Issue #12920

We are definitely getting less logs in, but there are still some HTTP -1 status codes. Is there a different way I should be handling the -1?

Answer 1

When the request is aborted or timed-out, the request lands as an error with status -1.

Taken from the official docs:

Also, status codes less than -1 are normalized to zero. -1 usually means the request was aborted, e.g. using a config.timeout.

timeout – {number|Promise} – timeout in milliseconds, or promise that should abort the request when resolved.
