javascript - $http.get(...).success is not a function

Question

i have this code:

app.controller('MainCtrl', function ($scope, $http){
  $http.get('api/url-api')
    .success(function (data, status, headers, config){
     }
}

In my local enviroment, works ok, but in a server, return this error:

TypeError: $http.get(...).success is not a function

Any ideas? Thanks

Answer 1

The .success syntax was correct up to Angular v1.4.3.

For versions up to Angular v.1.6, you have to use then method. The then() method takes two arguments: a success and an error callback which will be called with a response object.

Using the then() method, attach a callback function to the returned promise.

Something like this:

app.controller('MainCtrl', function ($scope, $http){
   $http({
      method: 'GET',
      url: 'api/url-api'
   }).then(function (response){

   },function (error){

   });
}

See reference here.

Shortcut methods are also available.

$http.get('api/url-api').then(successCallback, errorCallback);

function successCallback(response){
    //success code
}
function errorCallback(error){
    //error code
}

The data you get from the response is expected to be in JSON format. JSON is a great way of transporting data, and it is easy to use within AngularJS

The major difference between the 2 is that .then() call returns a promise (resolved with a value returned from a callback) while .success() is more traditional way of registering callbacks and doesn't return a promise.
