how to view http pending requests ($http.pendingRequests)

[zilabify]

Hi Guys,

$provide.factory('myHttpInterceptor', function($q, $http) {

  return {

    // optional method

    'request': function(config) {

      // do something on success

      console.log(config);

      console.log($http.pendingRequests);

      return config || $q.when(config);

    }

  }

});

$httpProvider.interceptors.push('myHttpInterceptor');

I'm getting Uncaught Error: [$injector:cdep] http://errors.angularjs.org/1.2.3/$injector/cdep?p0=myHttpInterceptor%20%3C-%20%24http

just wondering what should I inject to the property to view the http object?

Hi Zilabify,

your building an interceptor, so you want to know what other requests are going on during a in process $http request?

Your current solution is to try to inject $http, to the inside of $http. That's a circular reference, and is not going to work.

What is it you are trying to accomplish? I have looked, and didn't find an easy way to get hold of the http object inside a interceptor. 

I think you better use an decorator for what you need. (my guess, canceling pending request upon a new one?)

something like:

        $provide.decorator('$http', function($delegate) {

            // $delegate is the original $http!

            console.log($delegate.pendingRequests)

            return $delegate

        });

Hi Sander, 

Yes, here's a working plunk.

I manage to inject the http by injecting the $injector object, now problem is, how do I simulate pending requests? I always see a blank array.

What I want for the end product is, if there's a request that's looks like a duplicate http request, then cancel it.

Hi Zilabify,

launch a couple of requests, and make your backend pause a bit on each of them.

Or whip up some tests, and use that to test it!

I tried adding sleep in php before returning a request - doesn't work. 

Any help with an actual code is welcome.

Hi Zilabify,

an sleep(int $seconds) in your PHP should do the trick.
