Angular 相当于 jQuery deferred.always() 回调

Question

无论响应是否成功，我们都可以在jQuery中用.always()回调函数处理响应。

在 AngularJS 中是否有类似的用法？

//jQuery
$.get( "test.php" ).always(function() {
  alert( "$.get completed with success or error callback arguments" );
});

//AngularJS
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    //success
  }, function errorCallback(response) {
    //error
  });

//how can i handle always?

Answer 1

您可以使用 Angular promises 的 finally method。

Answer 2

用于此的 finally() method from $q 服务：

$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    //success
}).catch(function errorCallback(response) {
    //error
}).finally(function() {
    //Callback method
    //Executed always, no matter of success or fail
});

从 finally() 回调返回承诺时的重要通知：

finally returns a promise, which will become resolved with the same fulfillment value or rejection reason as promise. However, if callback returns a promise, the resolution of the returned promise will be delayed until the promise returned from callback is finished.
