Using $http inside a controller


The $http service is a function which generates an HTTP request and returns a promise.

General Usage


// Simple GET request example:
$http({
 method: 'GET',
 url: '/someUrl'
}).then(function successCallback(response) {
 // this callback will be called asynchronously
 // when the response is available
 }, function errorCallback(response) {
 // called asynchronously if an error occurs
 // or server returns response with an error status.
 });

Usage inside controller


appName.controller('controllerName',
 ['$http', function($http){
 // Simple GET request example:
 $http({
 method: 'GET',
 url: '/someUrl'
 }).then(function successCallback(response) {
 // this callback will be called asynchronously
 // when the response is available
 }, function errorCallback(response) {
 // called asynchronously if an error occurs
 // or server returns response with an error status.
 });
}])
