Access successCallback in AngularJs $http Method - angularjs

Question

I want to access to response successCallback(response)
var list_of_user = $http({
method: 'GET',
url: '/users/'
}).then(function successCallback(response) {
$scope.all_users = response.data;
}, function errorCallback(response) {
console.log(response);
});
console.log("$scope.all_users ", $scope.all_users)
is undefiend
I can access $scope.all_users from html, but how can I access to $scope.all_users in controller?

Answer 1

$http is async and console.log is executed before actually request is completed.
As you defined in comment that you want to compare two responses you can do that by simply putting a flag that will wait for both requests to finish.
var done = 0;
var onRequestFinishes = function() {
done += 1;
if (done < 2) {
return; // one of both request is not completed yet
}
// compare $scope.response1 with $scope.response2 here
}
and send first request and save response to $scope.response1 and invoke onRequestFinishes after that.
$http({
method: 'GET',
url: '/users/'
}).then(function successCallback(response) {
$scope.response1 = response.data;
onRequestFinishes();
}, function errorCallback(response) {
console.log(response);
});
Similarly send second request
$http({
method: 'GET',
url: '/users/'
}).then(function successCallback(response) {
$scope.response2 = response.data;
onRequestFinishes();
}, function errorCallback(response) {
console.log(response);
});

For request handling you can create individual promise chains and use $q.all() to execute code when all promises are resolved.
var request1 = $http.get('/users/').then(function(response)
{
console.log('Users: ', response.data);
return response.data;
}
var request2 = $http.get('/others/').then(function(response)
{
console.log('Others: ', response.data);
return response.data;
}
$q.all([request1, request2]).then(function(users, others)
{
console.log('Both promises are resolved.');
//Handle data as needed
console.log(users);
console.log(others);
}
