测试JSONP $资源AngularJS [英] testing JSONP $resource AngularJS

问题描述

我如何判断一个请求被发送并接收数据与JSONP服务？

How do I test a request being sent and data is being received with a JSONP service?

angular.module('search', [])
  .factory('SearchService', function($q,$rootScope,$resource) {
    var _search = {};
    _search.user = function(opts){
        return $resource('https://api.github.com/users/:user', {user: opts.user}, {
            search: {method:'JSONP',params:{callback: 'JSON_CALLBACK'}}
        });
    }
    return _search;
});

继GET请求的例子：

Following the GET request examples:

describe('search tests', function () {
    var svc, httpBackend;

    beforeEach(function (){  
      module('ngResource');
      module('search');
      inject(function($httpBackend, SearchService) {
        svc = SearchService;      
        httpBackend = $httpBackend;
      });
    });

    afterEach(function() {
      httpBackend.verifyNoOutstandingExpectation();
      httpBackend.verifyNoOutstandingRequest();
    });

    it('should send the message and return the response', function (){
        var returnData = { testing: 'anything'};
        httpBackend.expectJSONP('https://api.github.com/users/gigablox?callback=JSON_CALLBACK').respond(returnData);
        svc.user({user:'gigablox'}, function(user) {
            expect(user.testing).toEqual('anything');
        });
        httpBackend.flush();
    });
});

我似乎不能被一些错误得到：

I can't seem to get by some errors:

• 错误：没有挂起请求刷新


• 错误：预约等待人数：JSONP

• Error: No pending request to flush !
• Error: Unsatisfied requests: JSONP

的使用AngularJS 1.2和噶0.10.2 的

推荐答案

试着打电话给你的搜索这样的：

Try to call your search like the following:

svc.user({user:'gigablox'}).search(function(user) {
    expect(user.testing).toEqual('anything');
});

原因是调用 svc.user（）返回与搜索资源类对象（）方法。在搜索（）方法使用JSONP做出请求。如果没有调用搜索（）方法，$ httpBackend不会看到任何要求，所以你看在你的问题中提到的错误。

The reason is the call to svc.user() returns a resource class object with a search() method. The search() method uses jsonp to make request. Without calling the search() method, $httpBackend will not see any request, so you see the errors mentioned in your question.
