1.GET / signup--ms--(GET和POST均不起作用,有一段时间我不知道怎么了) 2.请检查以下代码 3.server.js。这是您所请求的应用代码。请仔细检查。链接的值也被单词link代替,因为它是私有的。 4.其中有两个文件。 Server.js和user.js请检查一下。

var router = require("express").Router();
var User = require("../models/user.js");
router.get("/signup", function(req, res){
    res.send("hello");
});

router.post('/signup', function(req, res, next){
    var user = new User();
    user.profile.name = req.body.name;
    user.email = req.body.email;
    user.password = req.body.password;
    User.findOne( { email : req.body.email }, function(err, existingUser) {
        if(existingUser){
            console.log(req.body.email + "already exists");
            return res.redirect("/signup");
        }
        else{
            user.save(function(err, user){
                if(err) return next(err);
                res.send("New user has been added");
            });
        }
    });
});

module.exports = router;




//server.js code
var express    = require("express");
var morgan     = require("morgan");
var mongoose   = require("mongoose");
var bodyParser = require("body-parser");
var User       = require("./models/user.js");
var ejs        = require("ejs");
var engine     = require("ejs-mate");


var app = express();
mongoose.connect('link', function(err){
    if(err){
        console.log(err);
    }
    else{
        console.log("connected to database");
    }
});

//middle ware
app.use(express.static(__dirname + '/public'));
app.use(morgan('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:true}));
app.engine("ejs", engine);
app.set("view engine", "ejs");

var mainRoutes = require("./routes/main.js");
var userRoutes = require("./routes/user.js");
app.use(mainRoutes,function(err){
    if(err){
        console.log("error is here")
    }
});
app.use(userRoutes, function(err){
    if(err){
        console.log("error is here in 2" );
    }
});

//listen to port 3000 
app.listen(3000, function(err){
    if(err) throw err;
    console.log("Server has started");
});

从app.use()中删除了回调函数,并且可以正常工作。
