错误：req#logout 需要回调函数

问题描述 投票：0回答：11

无法找到解决方案，尝试了一切，我只是使用护照的新手。 错误：req#logout需要回调函数我之前已经编码过，但那次我没有收到任何错误，但这次不知道为什么我得到这个，我也阅读了护照文档并尝试了所有解决方案

提前致谢

自 0.6.0 版本（撰写本文时几天前才发布）开始，

req.logout
是异步的。这是避免会话固定攻击的更大更改的一部分。

查看发布公告：

另一个主要变化是 

req.logout()
现在是异步函数，而以前它是同步函数。例如，以前的注销路线：

app.post('/logout', function(req, res, next) {
  req.logout();
  res.redirect('/');
});

应修改为：

app.post('/logout', function(req, res, next) {
  req.logout(function(err) {
    if (err) { return next(err); }
    res.redirect('/');
  });
});

Jared Hanson 提到文档还不是最新的：

为了提高注销期间会话管理方式的安全性，这是必要的。升级到 0.6.0 将要求应用程序将回调传递给 

req#logout
。我仍在努力更新文档和示例。

这里的学习者（也是？）——我也遇到了同样的问题。我正用头撞墙，直到教练提到

req.login()
需要回调函数。对于回调，他使用了错误处理函数，事实证明该函数也适用于 
req.logout()
。

也许你可以试试这个：

app.get("/logout", (req, res) => {
  req.logout(req.user, err => {
    if(err) return next(err);
    res.redirect("/");
  });
});

我在官方护照中找到了这段代码，它对我有用，我希望它也能解决您的问题 Passport 在 req 上公开了 logout() 函数 

app.get('/logout', function(req, res, next){
    req.logout(function(err) {
      if (err) { return next(err); }
      res.redirect('/');
    });
  });

如果您正在关注 Angela Yu 网络开发训练营，那么请使用这个，

app.get('/logout', function(req, res, next) {
  req.logout(function(err) {
    if (err) { 
      return next(err); 
      }
    res.redirect('/');
  });
});

这对我来说非常有效：

app.get("/logout", function(req, res, next) {
  req.logout(function(err) {
    if (err) { return next(err); }
    res.redirect("/");
  });
});

你也可以使用这个：

app.post("/logout", function(req, res, next) {
  req.logout(function(err) {
    if (err) { return next(err); }
    res.redirect("/");
  });
});

两者都有效，干杯！！！

如果这是在 Angela Yu 训练营。 用这个：

https://www.passportjs.org/tutorials/password/logout/

app.get("/logout", function(req,res,next){
  req.logout(function(err){
    if (err)
    {
      return next(err);
    }
    res.redirect("/");
  });
});

app.get('/users/logout', (req, res, next) => {
  req.logout(function (err) {
    if (err) {
      return next(err);
    }
    // if you're using express-flash
    req.flash('success_msg', 'session terminated');
    res.redirect('/login');
  });
});

这是我不起作用的问题：

app.get("/logout", (req, res) => {
  req.logout();
  res.redirect("/");
});

解决办法是：

require("dotenv").config();

const express = require("express");
const bodyParser = require("body-parser");
const ejs = require("ejs");
const mongoose = require("mongoose");
const session = require("express-session");
const passport = require("passport");
const passportLocalMongoose = require("passport-local-mongoose");

const app = express();
app.use(express.static("public"));

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

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

app.use(
  session({
    secret: "our little secret.",
    resave: false,
    saveUninitialized: false,
  })
);

app.use(passport.initialize());

app.use(passport.session());

mongoose.connect("mongodb://127.0.0.1/userDB");

const userSchema = new mongoose.Schema({
  email: String,
  password: String,
});

userSchema.plugin(passportLocalMongoose);

const User = new mongoose.model("User", userSchema);

passport.use(User.createStrategy());

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

app.get("/", (req, res) => {
  res.render("home");
});

app.get("/login", (req, res) => {
  res.render("login");
});

app.get("/register", (req, res) => {
  res.render("register");
});

app.get("/secrets", (req, res) => {
  if (req.isAuthenticated()) {
    res.render("secrets");
  } else {
    res.redirect("/login");
  }
});

app.get("/logout", function(req, res, next) {
  req.logout(function(err) {
    if (err) {
      return next(err);
    }
    res.redirect("/");
  });
});

我遇到了同样的错误。如果您使用这样的回调函数将会有所帮助。

router.get("/logout", (req, res) => {
  req.logout((err) => {
    if (err) {
      return res.status(500).json({ message: "Error during logout." });
    }
    res.status(200).json({ message: "Logout successful." });
  });
});
