this._verify 不是登录时的函数

Question

我正在尝试为我的投资组合制作一个 CRUD 应用程序。我希望用户能够注册并登录，然后进入一些东西（它是一个卡路里跟踪器）。用户可以注册，但是当我尝试登录时，我得到：

this.verify is not a function

这里是登录码：

// Authenticate Login
app.post("/login", (req, res, next) => {
    passport.authenticate("local", {
        successRedirect: "/myprofile",
        failureRedirect: "/login",
        failureFlash: true
    })(req, res, next);
});

passport.js

const LocalStrategy = require("passport-local").Strategy,
      bcrypt = require("bcryptjs");

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

module.exports = function(passport) {
    passport.use(
        new LocalStrategy({usernameField:"username"}, {passReqToCallback: true}, (username, password, done) => {
            // Check if there is a user with this username
            User.findOne({
                username: username
            }).then(user => {
                    if(!user) {
                        return done(null, false, {message: "There is not a user with this username"});
                    }
                    // Check if the password is correct
                    bcrypt.compare(password, user.password, (err, isMatch) => {
                        if(err) throw err

                        if(isMatch) {
                            return done(null, user)
                        } else {
                            return done(null, false, {message: "Password is invalid"})
                        }
                    });
                })
                .catch(err => console.log(err));
        })
    );

    passport.serializeUser((user, done) => {
        done(null, user.id);
    });

    passport.deserializeUser((id, done) => {
        User.findById(id, (err, user) => {
            done(err, user)
        })
    })
}

如果有人感兴趣或者您需要更多代码，我当然可以 post，我不确定还包括什么。但如果您喜欢，这里是 link 到 GitHub Repo。

感谢您的帮助，保持健康

Answer 1

如果您使用选项 passReqToCallback passport 期望 req-object 作为回调中的第一个参数传递：

passport.use(new LocalStrategy({
    usernameField: 'email',
    passwordField: 'passwd',
    passReqToCallback: true,
  },
  function(req, username, password, done) {
    // request object is now first argument
    // ...
  }
));
