this._verify is not a function on login

问题

I am trying to make a CRUD app for my portfolio. I want the user to be able to sign up and login and then to some stuff once inside (its a calories tracker). The user can Sign Up but when I try to login, I get:

this.verify is not a function

Here is the login code:

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

The 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)
        })
    })
}

If someone is interested or you need some more code I can of course post it, I am not sure what else to include. But if you are feeling like it, here is the link to the GitHub Repo.

Thank you for all your help, Stay well and healthy

回答1:

If you use the option passReqToCallback passport expects the req-object to be passed as the first argument in the callback:

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