[英]Passport.js: Cannot read property 'username' of undefined (Node)
我正在尝试实现passport-local但是在用邮递员测试时仍然出现此错误： Cannot read property 'username' of undefined
这是我的模型User.js ：
const mongoose = require('mongoose'); const {Schema} = mongoose; const passportLocalMongoose = require('passport-local-mongoose'); const User = new Schema({ username: String, email: String, password: String, firstName: String, lastName: String }); User.plugin(passportLocalMongoose); module.exports = mongoose.model('User', User);
路由： routes/authRoutes.js ：
const express = require('express'); const passport = require('passport'); const User = require('../models/User.js'); module.exports = app => { // POST to /register app.post('/api/register', (req, res) => { // Create a user object to save, using values from incoming JSON const newUser = new User({ username: req.body.username, firstName: req.body.firstName, lastName: req.body.lastName, email: req.body.email, }); // Save, via passport's "register" method, the user User.register(newUser, req.body.password, (err, user) => { // If there's a problem, send back a JSON object with the error if (err) { return res.send(JSON.stringify({ error: err })); } // Otherwise, for now, send back a JSON object with the new user's info return res.send(JSON.stringify(user)); }); }); }
index.js ：
const express = require('express'); const mongoose = require('mongoose'); const passportLocalMongoose = require('passport-local-mongoose'); const keys = require('./config/keys'); const session = require('express-session'); const passport = require('passport'); const LocalStrategy = require('passport-local').Strategy; const MongoStore = require('connect-mongo')(session); mongoose.connect(keys.mongoURI); const app = express(); app.use(require('express-session')({ secret: 'secretsecret', resave: false, saveUninitialized: false })); app.use(passport.initialize()); app.use(passport.session()); require('./routes/authRoutes')(app); // Configure Passport const User = require('./models/User'); passport.use(new LocalStrategy(User.authenticate())); passport.serializeUser(User.serializeUser()); passport.deserializeUser(User.deserializeUser()); require('./routes/authRoutes')(app); const PORT = process.env.PORT || 5000; app.listen(PORT);
还有我的package.json ：
{ "name": "server", "version": "1.0.0", "description": "", "main": "index.js", "engines": { "node": "8.1.1", "npm": "5.0.3" }, "scripts": { "start": "node index.js", "dev": "nodemon index.js" }, "author": "", "license": "ISC", "dependencies": { "connect-mongo": "^1.3.2", "express": "^4.15.4", "express-session": "^1.15.5", "mongoose": "^4.11.11", "passport": "^0.4.0", "passport-local": "^1.0.0", "passport-local-mongoose": "^4.2.1" } }
我已经检查了其他类似的问题，但是他们的解决方案不是我的解决方案，其中大多数没有初始化Passport。
edit:邮递员日志： POST http://localhost:5000/api/register { "username": "Test", "email": "testing@test.com", "password": "password", "firstName": "Testt", "lastName": "Teststs" }

您能告诉我们您的邮递员脚本正文吗？ 并确保使用Postman发送POST请求。
编辑：一切似乎都很好，形成你的结局。 我认为您需要安装bodyParser并将其用作中间件。
$ npm install --save body-parser
var bodyParser = require('body-parser')
app.use( bodyParser.json() );
app.use(bodyParser.urlencoded({
extended: true
}));
