Angularjs 无法发布/api节点

我无法将AngularJs表单的响应发布到我的Mongo DB数据库。下面是的代码片段

控制器：

   angular.module('myapp')
      .controller('AddCtrl', function($scope, $alert, Event) {
        $scope.addEvent = function() {
          Event.save({ eventName: $scope.eventName }).$promise
            .then(function() {
              $scope.eventName = '';
              $scope.addForm.$setPristine();
              $alert({
                content: 'Event has been added.'
              });
            })
            .catch(function(response) {
              $scope.eventName = '';
              $scope.addForm.$setPristine();
              $alert({
                content: response.data.message
              });
            });
        };
      });

app.post('/api/events', function (req, res, next) {
   var event = new Event();    // create a new instance of the Event model
    event.name = req.body.eventName;  // set the event name (comes from the request)

    event.save(function(err) {
      if (err)
        res.send(err);

      res.json({ message: 'Event Added!' });
    });

});

var eventSchema   = new Schema({
  name: String
});
var Event = mongoose.model('Event', eventSchema);

表单模板（html）：

<div class="container">
  <div class="panel panel-default">
    <div class="panel-heading">Add Events</div>
    <div class="panel-body">
      <form class="form" method="post" ng-submit="addEvent()" name="addForm">
        <div class="form-group" ng-class="{ 'has-error' : addForm.eventName.$invalid && addForm.eventName.$dirty }">
          <label class="control-label">Name</label>
          <input class="form-control" type="text" name="eventName" ng-model="eventName" placeholder="Select Event Name Here" required autofocus>
          <div class="help-block text-danger" ng-if="addForm.eventName.$dirty" ng-messages="addForm.eventName.$error">
            <div ng-message="required">Event name is required.</div>
          </div>
        </div>
        <button class="btn btn-primary" type="submit" ng-disabled="addForm.$invalid">Add</button>
      </form>
    </div>
  </div>
</div>

事件模式：

   angular.module('myapp')
      .controller('AddCtrl', function($scope, $alert, Event) {
        $scope.addEvent = function() {
          Event.save({ eventName: $scope.eventName }).$promise
            .then(function() {
              $scope.eventName = '';
              $scope.addForm.$setPristine();
              $alert({
                content: 'Event has been added.'
              });
            })
            .catch(function(response) {
              $scope.eventName = '';
              $scope.addForm.$setPristine();
              $alert({
                content: response.data.message
              });
            });
        };
      });

app.post('/api/events', function (req, res, next) {
   var event = new Event();    // create a new instance of the Event model
    event.name = req.body.eventName;  // set the event name (comes from the request)

    event.save(function(err) {
      if (err)
        res.send(err);

      res.json({ message: 'Event Added!' });
    });

});

var eventSchema   = new Schema({
  name: String
});
var Event = mongoose.model('Event', eventSchema);

我似乎不明白为什么会出现POST/api/events 404错误

编辑：还添加了GET/api/事件路由

app.get('/api/events', function(req, res, next) {
  Event.find(function(err, events) {
      if (err)
        res.send(err);

      res.json(events);
    });

});

app.get('/api/events/:id', function(req, res, next) {
  Event.findById(req.params.id, function(err, event) {
    if (err) return next(err);
    res.send(event);
  });
});

浏览器日志：

错误：[$injector:unpr]未知提供程序：EventProvider似乎您正试图与角度前端控制器共享mongoose模型。它们相互独立

我修改了
角度控制器
，使用
$http提供程序
向
/api/events
端点发送
POST
请求

angular.module('myapp')
    .controller('AddCtrl', function($scope, $alert, $http) {
        $scope.addEvent = function() {
            $http.post('/api/events', {
                eventName: $scope.eventName
            }).success(function(response) {
                $scope.eventName = '';
                $scope.addForm.$setPristine();
                $alert({
                    content: 'Event has been added.'
                });
            }).error(function(response) {
                $scope.eventName = '';
                $scope.addForm.$setPristine();
                $alert({
                    content: response.data.message
                });
            });
        };
    });

回答我自己的问题:

我创建了一个工厂服务

angular.module('myapp')
  .factory('Event', function($resource) {
    return $resource('/api/events/:_id');
  });

它现在工作正常。
发布您的事件服务您是否可以共享您的任何浏览器日志？是
res.send（err）这是发送erorr的原因？除了
事件
服务之外，如果能看到其他相关的快速路由，那就太好了。在请求发送到您的
/api/events
处理程序之前抛出404的东西。它只是发送POST/api/events 404 389msI在问题@MattG中添加了它们
