【问题标题】：angularjs error on server callback服务器回调上的angularjs错误

【问题描述】：

我正在使用资源调用服务器，当我转到的基本 URL 时

/viewEvent

它工作正常。我收到所有数据库条目。但是，当我去

/viewEvent/1234

其中 1234 是 eventID

我得到一个 undefined is not a function，这是 Angular 内部的崩溃。堆栈跟踪是

TypeError: undefined is not a function
at copy (http://localhost:8000/js/lib/angular/angular.js:593:21)
at http://localhost:8000/js/lib/angular/angular-resource.js:410:19

at done (http://localhost:8000/js/lib/angular/angular.js:9170:20)

at XMLHttpRequest.xhr.onreadystatechange   (http://localhost:8000/js/lib/angular/angular.js:9303:11) angular.js:575

当我检查服务器时，请求是正确的。我可以看到它得到了 1234，它从 mongo 数据库中提取了正确的条目。

这是控制器逻辑

.controller("viewEventsController", ["$scope", 'EventService', '$location', function($scope, EventService, $location){

    var path = $location.path().split('/');
    var pathSize = path.length;
    $scope.events = [];

    if(pathSize === 2){
        console.log("No event ID");

        $scope.events = EventService.query();

    }
    else{
        console.log("Event ID specified");
        EventService.get({"eventID": path[pathSize - 1]}, function(data){
            //$scope.events.push(data);
            console.log(data);
        }, function(error){
            console.log(error);
        });
    }
}]);

和服务逻辑

service.factory('EventService', function($resource){
    return $resource('api/viewEvent/:eventID');
});

它永远不会回到控制器，所以我“有信心”不是那样的。（看着它）

【问题讨论】：

查看此答案以正确使用将参数传递到 $resource (eventID)。 stackoverflow.com/questions/19365714/…

【解决方案1】：

不确定是否是最好的方法，但我通过这样做得到了它

在役：

service.factory('EventService', function($resource){
    return $resource('api/viewEvent/:eventID',
        {eventID:"@eventID"},
        {
            'getSingleEvent': {
            url: "api/viewEvent/:eventID",
            method: "GET",
            isArray: true
           }
        }
    );

控制器

var path = $location.path().split('/');
var pathSize = path.length;

EventService.getSingleEvent({"eventID":path[pathSize - 1]}, function(result){
        $scope.updateEvent();
    });

服务器

routes = require('./routes')
var router = express.Router();
router.get('/api/viewEvent/:eventID', routes.viewEvent);

在路由目录中我有一个 js 文件

var mongoose = require('mongoose');
var db = mongoose.createConnection('localhost', 'eventApp');
var eventSchema = require('../models/createEvent.js').eventSchema;
var event = db.model('events', eventSchema);

exports.viewEvent = function(req, res){

console.log(req.params.eventID);

if(req.params.eventID) {
    event.find({"_id": req.params.eventID}, function (error, events) {
        console.log(events);
        res.send(events);
    });
}
else{
    event.find({}, function (error, events) {
        console.log(events);
        res.send(events);
    })
}
};
