多个请求，相同的响应

Question

I'm facing this strange issue with the $http service: every request made to the API provided on the company that I work, wrapped in a $q.all(), return the same response.

var promises = [
    $httpPromiseA(),
    $httpPromiseB(),
    $httpPromiseC()
];

$q.all(promises)
    .then(function (response) {
        $log.log(response);
    });

// $log.log returns [expectedObjectFromA, expectedObjectFromA, expectedObjectFromA]

This occurs randomly: the expectedObjectFromA can be expectedObjectFromB or expectedObjectFromC. The fact is that all of the three objects return the same, or two of one and one of other, etc.

If I chain one after other, in a linear manner, they all work perfectly, but takes more time to acomplish the task, of course.

var def = $q.deferred();
var resolvedData = [];

$httpPromiseA()
    .then(function (response) {
        $log.log(response);

        resolvedData.push(reponse);

        return $httpPromiseB();
    })
    .then(function (response) {
        $log.log(response);

        resolvedData.push(reponse);

        return $httpPromiseC();
    })
    .then(function (response) {
        $log.log(response);

        resolvedData.push(reponse);

        return def.resolve(resolvedData);
    });

return def.promise();

// $log.log returns [expectedObjectFromA],
// [expectedObjectFromB] and [expectedObjectFromC]
// as expected. ResolvedData brings [expectedObjectFromA,
// expectedObjectFromB, expectedObjectFromC].

Can you give me some directions on what may be happening here?

I'm using the core implementations of $http and $q. I've tried one $q.allSettled, applied as $decorator, based on the API resource of Kris Kowalk's Q, but didn't succeed too.

Thanks.

EDIT 1:

I cannot pass the arguments to the functions separately because it's a wrapper function thats call the $http service, here in my app. The wrapper function expects a String as the first argument, and an Object as the second. The wrapper function returns the $http calls.

EDIT 2:

This Plunker calls 2 concurrent requests, one to the Instagram API and the other to the Flickr API. The problem don't occur is this Plunker. I really don't know how to deal with this trouble. This is REALLY annoying.

Answer 1

In $q.all you'll want to pass in an array of promises, instead executing the function. $httpPromiseA.$promise instead of $httpPromiseA() and so on.

Answer 2

The problem was on the server side, which was having problems with simultaneous requests, answering all made together with the same response.

Thanks for all support and attention.
