Question

我正在尝试将Passport js本地策略添加到我的nodejs应用程序。但是每次我将此文件添加到app.js时，都会收到类似这样的错误。在将password.js添加到app.js文件之前，该代码运行良好。

我不熟悉使用护照认证。我不知道问题出在哪里

C:\Users\adity\Desktop\thinkster\medium-api\node_modules\express\lib\application.js:210
    throw new TypeError('app.use() requires a middleware function')
    ^

这些是我的密码

config / passport.js

const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;
const mongoose = require('mongoose');
const User = require('../models/User');
mongoose.model('User');

passport.use(new LocalStrategy({
        username: 'user[email]',
        password: 'user[password'
    },function(email, password, done) {
    User.findOne({email: email}).then(function (user) {
        if(!user || !user.validPassword(password)){
            return done(null, false, {errors: {'email of password': 'is invalid'}});
        }
        return done(null, user);
    }).catch(done);
    }
));

app.js

 const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const passport = require('passport');
const session = require('express-session');

const app = express();

const conn = mongoose.connect('mongodb://localhost:27017/medium', {
    useNewUrlParser: true,
    useCreateIndex: true
});

app.use(session({secret: 'medium',
    cookie: {maxAge: 6000}, resave: false,
    saveUninitialized:false}));

app.use(passport.initialize());

if (!conn) {
    console.log('Error with database');
} else {
    console.log('Database Connected');
}
app.use(bodyParser.urlencoded({
    extended: false
}));
app.use(bodyParser.json());


app.use(require('./config/passport'));
app.use(require('./routes'));

const PORT = 8080;
app.listen(PORT, () => {
    console.log(`Server started on ${PORT}`);
});

尝试将导出添加到您的配置文件中

const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;
const mongoose = require('mongoose');
const User = require('../models/User');
mongoose.model('User');

module.exports = passport.use(new LocalStrategy({
        username: 'user[email]',
        password: 'user[password'
    },function(email, password, done) {
    User.findOne({email: email}).then(function (user) {
        if(!user || !user.validPassword(password)){
            return done(null, false, {errors: {'email of password': 'is invalid'}});
        }
        return done(null, user);
    }).catch(done);
    }
));

我还没有测试过，只是猜测，所以让我知道这是否有效;）
