javascript - res.jwt 不是一个函数 - NodeJS Express

Question

我不断得到

res.jwt is not a function 

我已经安装了jwt-express并像这样导入

import jwt from 'jwt-express'  

这是我的auth.js

import Account from '../services/account.js'
import env from 'dotenv'
import _ from 'lodash'

const dotenv = env.config();

module.exports = {
    /**
     * Process the user login, generating and returning a token if successful.
     *
     * @return {res}
     */
    async login(req, res, next) {
        try {
            let origin = req.headers.origin;
            let accounts = await Account.getAccounts();

            let account = _.find(accounts, {
                'email_address' : req.body.username,
                'password' : req.body.password
            });

            if (!account) {
                res.send('Username/Password Wrong');
            }

            // res.send(account);

            let authentication = res.jwt({
                'email': account.email_address,
                'id': account.account_id
            });
            res.send(authentication);

        } catch (error) {
            next(error)
        }
    }
};

index.js

import express from 'express'
import favicon from 'serve-favicon'
import path from 'path'
import bodyParser from 'body-parser'
import bluebird from 'bluebird'
import jwt from 'jwt-express'
import env from 'dotenv'

//Controllers
import fortinetController from './controllers/fortinet'
import authController from './controllers/auth.js'

//Logger
import logger from './config/logger.js'

//Constant
const router = express.Router();
const app = express();
const PORT = 3000;
const dotenv = env.config();
Promise = bluebird;

app.use(bodyParser.urlencoded({extended: true }));
app.use(bodyParser.json());
app.use(router)
app.use(express.static('public'))
app.use(favicon(path.join(__dirname,'public','favicon.ico')))
app.use(jwt.init('CARWASH', {cookies: false }));


router.get('/', (req,res) => {
    res.send('Welcome to the backend provisioning daemon to program FortiManager')
});

router.post('/login', authController.login);

//Fortinet
router.post('/fortinet/login', fortinetController.login);
router.post('/fortinet/getSessionTimeOut', fortinetController.getSessionTimeOut);
router.post('/fortinet/logout', fortinetController.logout);

//Error handling function
app.use((err,req,res,next) => {
    console.error(err.stack)
    res.status(500).send(`Red alert! Red alert!: ${err.stack}`)
    logger.error(`${req.method} ${req.url} - ${err.log || err.message}`);
});

app.listen(PORT, () => {
        console.log(`Your server is running on ${PORT}`)
    }
);

如何调试这个？

我尝试添加这个

console.log(jwt);

Answer 1

1. 您没有正确配置 express-jwt。
2. 您使用的 express-jwt 完全错误。

让我们逐一讨论一下。

我不确定为什么您认为在文档 here 时需要调用 jwt.init(...)状态简单地执行:jwt(...)。因此您需要进行以下更改:

改变

app.use(jwt.init('CARWASH', {cookies: false }));

至

app.use(jwt({secret: 'CARWASH'}));

不存在 cookies 选项，不确定您从哪里获得该选项。

现在 express-jwt 将仅处理 JWT 的验证。它不会生成 JWT，就像您在 auth.js 中尝试执行的那样。

为了生成 JWT，您将需要另一个模块:jsonwebtoken 。然后，您将在 auth.js 中使用该模块，如下所示:

import jwt from "jsonwebtoken";
// ...

module.export = {
    async login(req, res, next) {
        try {
            // ... auth logic omitted

            // Here we generate the JWT
            // Make sure the JWT secret is the SAME secret you used for express-jwt
            let authentication = jwt.sign({
                'email': account.email_address,
                'id': account.account_id
            }, 'CARWASH');
            res.send(authentication);
        }
        catch (error) {
            next(error);
        }
    }
}
