使用API​​与Mongoose的Javascript问题

Question

我正在创建一个简单的AngularJS SPA并使用API​​连接到Mongoose。但是当我只是尝试添加一个新成员时，我一直收到以下错误，该成员确实添加到了猫鼬但在我刷新之前不会在我的网页上看到。当我按添加成员按钮时，我在Google Chrome开发工具中收到以下错误：

TypeError：无法读取属性＆＃39;成功＆＃39;未定义的     在Scope。$ scope.addMember（app.js：195）

我不知道如何绕过它。这是我的app.js

app.controller('MembersController', ['$scope','SimpleFactory',
    function ($scope,SimpleFactory) {

        SimpleFactory.getMembers()
        .success(function(members) {
        $scope.members = members;
        });

    $scope.addMember = function()
    {
        var member = {
            name: $scope.newMember.name,
            address: $scope.newMember.address,
            age : $scope.newMember.age,
            level : $scope.newMember.level,
            swimmer : $scope.newMember.swimmer,
            email : $scope.newMember.email,
            regdate : $scope.newMember.regdate,
                    }

          SimpleFactory.addMember(member)
          .success(function(added_member) 
          { 
             $scope.members.push(added_member);
             $scope.newMember = { }
          }       );
    }

    $scope.membNoInRange = function () 
    {
        return  $scope.memberNo && $scope.memberNo >=0 
                        && $scope.memberNo < $scope.members.length
    }
}])

添加我的工厂服务：

app.factory('SimpleFactory', ['$http', function($http){

var members =  $http.get('/api/members') 

factory.getMembers = function () 
    {
        return members = $http.get('/api/members');
    }

   factory.getMember = function (index) {
        if (index >=0 && index < members.length ) {
           return  members = $http.get('/api/members/' + member_id )
       }
       return undefined
    }

    factory.addMember = function(member) {
         $http.post('/api/members',member)
    }
    factory.updateMember = function(index,member) {
         $http.put('/api/members/' + member_id, member)
    }

     return factory;
}])

任何人都可以提供帮助，我是否需要提供更多信息？

服务的功能不会返回承诺。

尝试在$ http ...

之前添加return

factory.addMember = function(member) {
     return $http.post('/api/members', member)
}
factory.updateMember = function(index,member) {
     return $http.put('/api/members/' + member_id, member)
}
