Angularjs - $http success vs then

问题

I want to ask about the difference about this method My concern is difference between .then and .success, function and also .error thanks.

// 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.
});

and

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

Both .then() and .sucess() are refer to promise it run asynchronously and wait for the response if it fullfied your request then resolve it otherwise reject it.

.success and .error are deprecated you can find more details on documentation
