Question

这是我的app.js

var express               = require("express")
var User                  = require("./models/user");
var bodyParser            = require("body-parser");
var mongoose              = require("mongoose");
var passport              = require("passport");
var passportStrategy      = require("passport-local");
var passportLocalMongoose = require("passport-local-mongoose");



//mongo db
mongoose.connect("mongodb://localhost/auth_demo_app");



var app = express();
app.set('view engine', 'ejs');
app.use(bodyParser.urlencoded({extended: true }));
app.use(require("express-session")({
  secret: "Rusty",
  resave: false,
  saveUninitialized: false
}));

app.use(passport.initialize());
app.use(passport.session());
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());


//ROUTS
app.get("/", function(req,res) {
  res.render("home");
});

app.get("/secret", function(req,res) {
  res.render("secret");
});

//Auth Routhes
//show the form
app.get("/register", function(req,res) {
  res.render("register");
});


app.post("/register", function(req,res) {
  req.body.username
  req.body.password
  User.register(new User({username: req.body.username}), req.body.password, function(err, user) {
    if(err) {
      console.log(err);
      return res.render('register');
    }
    passport.authenticate("local")(req, res, function(){
        res.redirect("/secret");
    });
  });
});



//this is the locall host
app.listen(3002, function(){
  console.log("Server on port 3002")
});

这是用户模型user.js

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);

有人可以帮助我发现为什么我的页面一直处于等待状态的问题吗？因为我在 User.register 所在的行中没有发现代码的任何问题解决问题。看起来它无法进入此方法，但我仍然不确定为什么如果发现错误，那就太好了。

因为每次我查看stackoverflow时，我都会看到人们忘记像以前那样放置用户模型。但事实并非如此

你需要添加这一行：

passport.use(User.createStrategy());

在上面添加：

passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

这样做，您的代码将是：

var express               = require("express")
var User                  = require("./models/user");
var bodyParser            = require("body-parser");
var mongoose              `enter code here`= require("mongoose");
var passport              = require("passport");
var passportStrategy      = require("passport-local");
var passportLocalMongoose = require("passport-local-mongoose");



//mongo db
mongoose.connect("mongodb://localhost/auth_demo_app");



var app = express();
app.set('view engine', 'ejs');
app.use(bodyParser.urlencoded({extended: true }));
app.use(require("express-session")({
  secret: "Rusty",
  resave: false,
  saveUninitialized: false
}));

app.use(passport.initialize());
app.use(passport.session());
passport.use(User.createStrategy);
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

尝试一下

Users=new User({ username : req.body.username, name : req.body.name,
email: req.body.email });


 User.register(Users, req.body.password,function(err, user) {
        if (err) {

          if(err.name === "UserExistsError" ){
            res.json({success:false, message: "Username  already exist"})
            }else{

          res.json({success:false, message:"Your account could not be saved. Error: ", err})
            }
        }else{
          res.json({success: true, message: "Your account has been saved, Now you can login!"})
        }
      });
