使用带有socket.io的passport.js时出现错误请求

Question

我正在使用node.js express socket.io和mongodb制作聊天应用程序。我已使用passport.js为注册路由添加了身份验证功能，如下面的代码所示。我正在尝试注册时收到错误请求。它发生在第133行。我已经打印出了请求，对于任何能解决这个问题的人都会有很大的帮助。我搜索谷歌很多，找不到解决方案。 （检查下面的验证功能。我的其他文件如下：

以下是app.js代码

var express = require("express"),

	
	mongoose = require("mongoose"),

	app     = express(),

	server  = require("http").createServer(app),

	bodyParser = require("body-parser"),

	//Authentication tools
	passport 		= require("passport"),
	LocalStrategy 	= require("passport-local"),


	//require all models

	User = require("./models/user");


//Connect a database
var url = process.env.DATABASEURL || "mongodb://localhost/chatApplication";
mongoose.connect(url);


app.set("view engine","ejs");

app.use(bodyParser.urlencoded({extended:true}));
app.use(bodyParser.json());


//Passport Authentication(Keep at end)

	//creating a session.

user.js的（模型）

var mongoose = require("mongoose");
var passportLocalMongoose = require("passport-local-mongoose");

var userSchema = new mongoose.Schema({
    username: String,
    password: String
});



userSchema.plugin(passportLocalMongoose);
module.exports = mongoose.model("User",userSchema);
