Question

我正在node.js中构建一个简单的回合制游戏，并且我使用本地托管的mongoDB 100％运行，套接字事件工作正常，但是当我从本地数据库（使用mongo）更改为mLab时mongoDB托管它停止工作，我仍然可以登录并正确注册帐户，数据库仍然返回完全相同的结果，所以它显然没有连接和查询数据库的麻烦。但我完全迷失了问题所在。当我更改数据库URL时，它永远不会触发socket.emit（'key'）事件;

然而，它确实触发了客户端套接字上的（'find match'）事件，但服务器从不处理它。（它不会在服务器上记录“findMatch”。

服务器正在记录“连接”但从未接收任何其他套接字事件。

即使我没有得到解决方案，我只是完全陷入困境，试图调试问题发生的地方，所以任何类型的输入都会非常感激

这是我在控制台中的套接字调试日志。

var express = require('express');
app = express();
http = require('http').Server(app);
io = require('socket.io').listen(http);
mongoose = require('mongoose');
passport = require('passport');
flash = require('connect-flash');
morgan = require('morgan');
bodyParser = require('body-parser');
cookieParser = require('cookie-parser');
session = require('express-session');
methodOverride = require('method-override');
User = require('./models/user');


var configDB = require('./config/database.js');
mongoose.connect(configDB.url);

mongoose.connection.on('error', console.error);

app.use(express.static('public', {redirect: false}));
app.use(express.static('private/tests', {redirect: false}));


app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
//app.use(methodOverride());
app.use(cookieParser());
app.set('view engine', 'ejs');

require('./config/passport')(passport);

app.use(session({secret: 'password'}));
app.use(passport.initialize());
app.use(passport.session());
app.use(flash());

passport.serializeUser(function(user, done) {
    done(null, user.id);
});

// used to deserialize the user
passport.deserializeUser(function(id, done) {
    User.findById(id, function(err, user) {
        done(err, user);
    });
});


require('./routes')(app,passport);

var rooms = [];


io.sockets.on('connection', function(socket){
    console.log("connection");

    socket.on('key', function(data){
        console.log("key");
        socket._id = data.user_id;
        socket.nickname = data.username;
        socket.rank = data.rank;

        socket.on('findMatch', function() {
            console.log('findMatch');
            //do some other stuff
        });

然后在客户端我有这个设置

scotchApp.controller('lobbyController', function ($scope, $http) {
    $http.get('/play').then(function successCallback(results){
        socket.on('connect',function(){
            console.log("emit key")
            socket.emit('key',{
                user_id: results.data._id,
                username: results.data.local.email,
                rank: results.data.local.rank,
            });
        });

        $scope.findMatch = function(){
            console.log('looking for match');
            socket.emit('findMatch')
        };

NodeJS socket.io事件从客户端触发但未在服务器上接收
