角$ HTTP / jQuery的完全等同 [英] angular $http / jquery complete equivalent

问题描述

有没有办法模仿jQuery的'完整'具有角$ HTTP模块的回调？我有一些code，我想执行不管请求是成功还是失败，这时候我发现自己不得不写这篇文章：

Is there a way to emulate jquery 'complete' callback with angular $http module? I have some code I would like to execute no matter whether the request succeeded or failed and at the moment I find myself having to write this:

$http.get(someUrl).success(function(){
        successCode();
        completeCode();
    }).error(function(){
        errorCode();
        completeCode();
    })

但我宁愿写的是这样的：

but I would rather write something like:

$http.get(someUrl).success(function(){
        successCode();
    }).error(function(){
        errorCode();
    }).complete(function(){
        completeCode();
    })

我试着用同样的承诺API，但我最终有同样的问题。任何建议？

I've tried also using the promise API but I end up having the same problem. Any suggestion?

推荐答案

更新2014年8月： 。总是已更名为。最后在最新版本的角。 preFER 。最后到。总是。

Update Aug 2014: .always has been renamed .finally in recent versions of Angular. Prefer .finally to .always.

请注意，为了支持IE8你有括号来称呼它为 [终于] 。

Note that in order to support IE8 you have to call it with bracket notation as ["finally"].

您可以在AngularJS使用。总是

You can use .always in AngularJS

这变化的而新的（你可以做，在jQuery的一段时间），你可以看到提交的 这里 。这需要你有AngularJS 1.1.5或更高版本。

This change is rather new (you could do that in jQuery for a while), you can see the commit here. This requires you to have AngularJS 1.1.5 or higher.

总是（回调） - 允许你观察一个承诺的任何履行或拒绝，
     但这样做不修改的最终值。这是有用的，以释放资源或者做一些
     做清理，需要承诺是否已经被拒绝或解决。请参见全
     为规范
     更多信息。

always(callback) – allows you to observe either the fulfillment or rejection of a promise, but to do so without modifying the final value. This is useful to release resources or do some clean-up that needs to be done whether the promise was rejected or resolved. See the full specification for more information.
