$ resource回调(错误和成功)

Question

我使用AngularJS 1.1.3来使用带有promise的新$资源...

我如何从中获得回调？我尝试的方式与$ http相同:

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

但是没有"成功"和"错误"功能......

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"成功,得到数据",即使回报是404 ...

任何的想法？

谢谢

对于角度资源和角度1.2 的PR,角度将切换到执行成功/错误检查的更简单方式.Resource.get(..)和instance.get()都不支持附加回调或$ then方法,而是支持$ promise方法,后者自然会为两者返回一个promise.

从角度1.2开始,$ promise功能将上线:$ promise更改

将"获取"请求更改为这些行(原始示例在angularjs.org首页上):

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;
});

在控制器中的其他位置,您可以实例化资源"Project"实例,您可以在其中使用相同的接口来获取成功和错误:

var myProject = new Project();

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

var MyResource = $resource("/my-end-point/:action", {}, {
    getSomeStuff: { method:"GET", params: { action:"get-some-stuff" }, isArray: true },
    getSingleThing: { method:"GET", params: { action:"get-single-thing" }, isArray: false }
});

function MyController(MyResource) {
    var itemList = MyResource.getSomeStuff({}, function success() {}, function err() {});
    // will call: /my-end-point/get-some-stuff
    // will be array. each object is resource's instance
    var item = MyResource.getSingleThing({id:123}, function success() {}, function err() {});
    // will call: /my-end-point/get-single-thing?id=123
    // will be object. an instance of resource
}
