Express Js 无法重定向

Question

我正在构建一个简单的应用程序，它有 2 个页面，即登录页面和一个受保护页面。我有一个中间件，它检查用户是否登录尝试访问路由 /protected 如果用户已登录，他将被授予访问权限，否则将重定向到 /login

如果密码匹配，用户现在将获得一个会话并重定向到 /protected 我的代码不起作用，它一直将我重定向到 /login 而不是 /protected 即使登录详细信息是 coorect

这是我的代码

const express = require('express');
const app = express();
const port = 8080;
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const multer = require('multer');
const upload = multer();
const session = require('express-session');
const cookieParser = require('cookie-parser');
mongoose.connect("mongodb://localhost/Barclays_Bank", 
{useUnifiedTopology:true,useNewUrlParser:true,useFindAndModify:false,useCreateIndex:true});
app.set('view engine','pug');
app.set('views','./views');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(upload.array());
app.use(cookieParser());
app.use(session({secret:"secret",cookie:{maxAge:60000},resave:true, saveUninitialized:true}));

var staffschema = mongoose.Schema({
email:{
    type:String,
    unique:true,
},
password:{
    type:String,
    password:String,
}
})
var staff = mongoose.model("staff",staffschema);
 //Route To Render login Page
app.get('/login',(req,res)=>{
res.render('login');
});

//Route To Handle Post request on login page
app.post('/login',(req,res)=>{
staff.findOne({email:req.body.email})
.then((result)=>{
        if(req.body.password === result.password){
            req.session.currentstaff = staff;
            res.redirect('/login');
    }
    else{
        console.log('User Not Found!!!');
    }
})
.catch((err)=>{
    console.log("Error!!!");
})
})

//Middleware Function 
ensureIsLoggedIn =(req,res,next)=>{
if(req.session.currentstaff){
    next();
}else{
    res.redirect('/login');
}
};

//Route To Render Protected Page
app.get('/protected',ensureIsLoggedIn,(req,res)=>{
res.render('protected');
})

//Route to handle post request on logout
app.post('/logout',(req,res)=>{
req.session.destroy((err)=>{
    res.redirect('/login');
    console.log('User loggedout');
})
})

//port
app.listen(port,()=>{
console.log('App is running...');
})

看起来您正在将用户重定向到 /login 路由，即使他们已在此处成功登录

if(req.body.password === result.password){
 req.session.currentstaff = staff;
 res.redirect('/login'); // you should redirect the user to the '/protected' route
}
