Question

我在ubuntu上使用node.js：sailsjs

node version: 0.10.37
sails version: 0.11.0
npm version: 1.4.28
ubuntu version: 14.04.2

我正在尝试将GCM推送通知服务返回的值记录到mysql表中。我正在登录db表的推送通知服务（PushNotifications.js文件）的部分如下所示：

var req = https.request(options, function(res) {
    res.setEncoding('utf8');
    res.on('data', function (chunk) {
        console.log('Response from GCM: ' + chunk);
                    GcmLog.add(recipients, chunk, function(err, response){
                        if(err){
                            res.serverError(err);
                        }else{
                            res.json({msg: 'yes'});
                        }
                    });
    });
});

GcmLog.js模型具有以下函数将数据推送到db表中：

  add: function(device_id, chunk, callback){
        GcmLog.create({user: device_id, log: chunk}).exec(function(err, response){
            if(err){
                return callback(err, null);
            }else{
        callback(null, response);
      }
    });
  }

当我发送推送通知时，消息传递成功并显示在Android设备上，但没有任何内容记录到数据库表中。我在应用程序的日志文件中收到以下错误：

然后服务器在多次尝试后崩溃并重新启动。我无法找出原因。任何帮助解释正在发生的事情以及如何克服这一点，将不胜感激。

对象＃<incomingmessage>没有方法＆＃39; serverError＆＃39;
