**我一辈子也搞不清楚我到底做错了什么。 我对passport和js都很陌生，但任何帮助都将不胜感激！ 每次尝试运行时，我得到的authenticate不是一个函数，那么如果我在htmlroutes.js中需要passport，我得到的findOne不是一个函数。 非常困惑**

这是我的passport.js

const passport = require("passport");
const LocalStrategy = require("passport-local").Strategy;
const User = require("../routes/htmlRoutes");

passport.use(
new LocalStrategy({ usernameField: "email" }, function (
email,
password,
done
) {
User.findOne({ email: email }, function (err, user) {
  if (err) {
    return done(err);
  }
  if (!user) {
    return done(null, false, { message: "Incorrect Email..." });
  }
  if (!user.validPassword(password)) {
    return done(null, false, { message: "Incorrect password..." });
  }
  return done(null, user);
});
})
);

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

passport.deserializeUser(function (id, done) {
User.findById(id, function (err, user) {
done(err, user);
});
});

module.exports = passport;

我的架构

const mongoose = require("mongoose");
const Schema = mongoose.Schema;

const userSchema = new Schema({
first_name: {
type: String,
required: true,
},
last_name: {
type: String,
required: true,
},
email: {
type: String,
required: true,
unique: true,
},
password: {
type: String,
required: true,
},
});

module.exports = mongoose.model("User", userSchema);

我的htmlroutes.js。 在这里，如果我将passport更改为required（“passport”），我会丢失authenticate的错误，但是这样做对我来说没有任何意义

const express = require("express");
const Router = express.Router();
const User = require("../models/User");
const passport = require("../config/passport");

Router.get("/", (req, res) => {
res.render("index");
});

Router.post(
"/login",
passport.authenticate("local", {
successRedirect: "/dashboard",
failureRedirect: "/login",
failureFlash: true,
})
);

Router.get("/dashboard", (req, res) => {
res.render("dashboard");
});

Router.post("/new/users", (req, res) => {
User.create({
first_name: req.body.first_name,
last_name: req.body.last_name,
email: req.body.email,
password: req.body.password,
}).then((data) => {
res.send(data);
});
});

module.exports = Router;
