Question

我花了两天时间寻找答案，但无济于事。

当我尝试注册用户时，重定向无法执行。它在数据库中创建用户，但不会重定向到主页。最终，即使它是全新用户，它也会超时并引发此错误A user with the given username is already registered。似乎创建了用户，然后重试。

我在另一个Web应用程序中使用了相同的代码（如下），没有任何问题。非常感谢您的帮助。

App.js

Member.js

const express = require('express')
const router = express.Router()
const passport = require('passport')
const User = require('../models/user')

//Register Routes

用户模型

const mongoose = require('mongoose')
const passLocMon = require('passport-local-mongoose')

const userSchema = mongoose.Schema({
  email: {type: String, unique: true, required: true},
  password: String,
  firstName: {type: String, required: true},
  lastName: {type: String, required: true},
})

userSchema.plugin(passLocMon, {
  usernameField: 'email', 
  passwordField: 'password'
})

module.exports = mongoose.model('User', userSchema)

我找到了！！结果是在寻找先前错误的答案时，我在下面的代码部分中删除了一组括号...

passport.use(new LocalStrategy({
  usernameField: 'email',
  passwordField: 'password'
},
  User.authenticate))

我忘记加回用于调用User.authenticate（）的括号。
