用于查询错误转换的角资源返回列表

Question

尝试使用角资源从API中提取项目列表。如果我从浏览器点击并使用swagger，我会得到一个json项目列表。

但无法通过角度上的错误输出页面上的结果列表。

.factory('ProjectsDS', ['$resource','$timeout',
                        function($resource, $timeout){console.log(0);

                        var proj = $resource('/projects');
                            $timeout(2000);
                        console.log( 0 + ' ' + proj.query().length);


                          return $resource('/projects')}])

浏览器控制台中的错误：

"Error: [$resource:badcfg] http://errors.angularjs.org/1.5.5/$resource/badcfg?p0=Error%20in%20resource%20configuration%20for%20action%20%60%7B0%7D%60.%20Expected%20response%20to%20contain%20an%20%7B1%7D%20but%20got%20an%20%7B2%7D%20(Request%3A%20%7B3%7D%20%7B4%7D)&p1=query&p2=array&p3=object&p4=GET&p5=%2Fprojects

"

我认为，使用超时来处理初始的空返回对象。长度输出为0。

API如果浏览到：

{"_links":{"self":{"href":"http:\/\/localhost:8000\/projects?page=1"},"first":{"href":"http:\/\/localhost:8000\/projects"},"last":{"href":"http:\/\/localhost:8000\/projects?page=1"}},"_embedded":{"projects":[{"id":"1","message":null,"timestamp":null,"user":null,"name":"First 1","site":"https:\/\/www.nathanhaley.com","description":"This is one description.","_links":{"self":{"href":"http:\/\/localhost:8000\/projects\/1"}}},{"id":"2","message":null,"timestamp":null,"user":null,"name":"First 1","site":"https:\/\/www.nathanhaley.com","description":"This is one description.","_links":{"self":{"href":"http:\/\/localhost:8000\/projects\/2"}}},{"id":"3","message":null,"timestamp":null,"user":null,"name":"First 2","site":"https:\/\/www.nathanhaley.com","description":"This is one description.","_links":{"self":{"href":"http:\/\/localhost:8000\/projects\/3"}}},{"id":"4","message":null,"timestamp":null,"user":null,"name":"First 12","site":"https:\/\/www.nathanhaley.com","description":"This is one description.","_links":{"self":{"href":"http:\/\/localhost:8000\/projects\/4"}}}]},"page_count":1,"page_size":25,"total_items":4,"page":1}

谢谢你的帮助。

根据记录的错误：

当$resource服务期望将响应反序列化为数组，但接收对象时，则会发生此错误，反之亦然。

在这一行上：console.log( 0 + ' ' + proj.query().length);尝试使用.get()而不是.query()
