AngularJs ReferenceError: $http is not defined

Question

I have the following Angular function:

$scope.updateStatus = function(user) {    
    $http({
        url: user.update_path, 
        method: \"POST\",
              


        

Answer 1

Just to complete Amit Garg answer, there are several ways to inject dependencies in AngularJS.

You can also use $inject to add a dependency:

var MyController = function($scope, $http) {
  // ...
}
MyController.$inject = ['$scope', '$http'];

Answer 2

Probably you haven't injected $http service to your controller. There are several ways of doing that.

Please read this reference about DI. Then it gets very simple:

function MyController($scope, $http) {
   // ... your code
}

Answer 3

I have gone through the same problem when I was using

    myApp.controller('mainController', ['$scope', function($scope,) {
        //$http was not working in this
    }]);

I have changed the above code to given below. Remember to include $http(2 times) as given below.

 myApp.controller('mainController', ['$scope','$http', function($scope,$http) {
      //$http is working in this
 }]);

and It has worked well.
