$资源回调（错误和成功） [英] $resource callback (error and success)

问题描述

I'm使用AngularJS 1.1.3使用与承诺的新的$资源...

I´m using AngularJS 1.1.3 to use the new $resource with promises...

我怎样才能得到回调？
我试图以同样的方式我$ HTTP所做的：

How can I get the callback from that? I tried the same way I did with $http :

$resource.get('...').
  success(function(data, status) {
      alert(data);
   }).
   error(function(data, status) {
      alert((status);
   });

但没有'成功'既不是'错误'的功能...

But there is no 'success' neither 'error' functions...

我也试过了：

$resource.get({ id: 10 },function (data) {
   console.log('success, got data: ', data);
 }, function (err) {
   alert('request failed');
 });

这总是打印的成功，得到了数据即使返回的是一个 404 ...

That always print "success, got data" even if the return is a 404 ...

任何想法？

感谢

推荐答案

作为 PR上angulars的资源 和1.2角，角将切换到执行成功/错误检查的一个简单的方法。而不是附加回调或$则方法，无论是Resource.get（..）和instance.get（）将支持$诺方法，这自然会返回为一个承诺。

As of a PR on angulars resource and angular 1.2, angular will be switching to a simpler way of performing success / error checking. Instead of attaching callbacks or a $then method, both the Resource.get(..) and instance.get() will support the $promise method, which naturally returns a promise for both.

由于角1.2的$承诺的功能还会去住：<一href=\"https://github.com/angular/angular.js/commit/05772e15fbecfdc63d4977e2e8839d8b95d6a92d\">$promise更改

As of angular 1.2 the $promise feature will go live: $promise changes

改变你的得到的要求是东西沿着这些路线（原来的例子是angularjs.org头版）：

Change your "get" request to be something along these lines (original example is on angularjs.org front page):

factory('Project', function($resource) {
  var Project = $resource('https://api.mongolab.com/api/1/databases' +
      '/youraccount/collections/projects/:id',
      { apiKey: 'yourAPIKey' }, {
        update: { method: 'PUT' }
      }
  );

  Project.prototype.update = function(cb) {
    return Project.update({id: this._id.$oid})
      .$promise.then(
        //success
        function( value ){/*Do something with value*/},
        //error
        function( error ){/*Do something with error*/}
      )
  };

  Project.prototype.destroy = function(cb) {
    return Project.remove({id: this._id.$oid})
      .$promise.then(
        //success
        function( value ){/*Do something with value*/},
        //error
        function( error ){/*Do something with error*/}
      )
  };

  return Project;
});

在其他地方，在一个控制器可能实例化一个资源项目例如，你可以使用的成功和错误相同的接口：

Somewhere else in the a controller you may instantiate a resource "Project" instance where you can use the same interface for successes and errors:

var myProject = new Project();

myProject.$get({id: 123}).
   .$promise.then(
      //success
      function( value ){/*Do something with value*/},
      //error
      function( error ){/*Do something with error*/}
   )
