TypeError: Cannot read property 'authorization' of undefined using express-jwt

Question

我正在尝试为我正在使用的路由添加身份验证 express-jwt 我添加了这个中间件来保护 post 创建路由。但是在测试时我在 postman.

中得到了错误

error

TypeError: Cannot read property 'authorization' of undefined<br>    at Object.getTokenFromHeaders [as getToken]

这些是我的 express jwt 代码

auth.js

import  jwt from 'express-jwt';
const getTokenFromHeaders = (req) => {
    const { headers: { authorization } } = req;
    console.log(authorization);     <----- in this log i am getting token
    if(authorization && authorization.split(' ')[0] === 'Token') {
        return authorization.split(' ')[1];

    }
    return null;
};

const auth = {
    required: jwt({
        secret: 'secret',
        userProperty: 'payload',
        getToken: getTokenFromHeaders,
    }),
    optional: jwt({
        secret: 'secret',
        userProperty: 'payload',
        getToken: getTokenFromHeaders,
        credentialsRequired: false,
    }),
};

module.exports = auth;

routes.js

routes.post('/post', auth.required, postController.post);

Answer 1

你在这行有错误：

const { headers: { authorization } } = req.body;

因为headers prop是在req对象上，而不是在req.body上，所以应该是这样的：

const { headers: { authorization } } = req;

Answer 2

使用const authorization = req.headers.authorization应该可以解决问题

Answer 3

这个解决方案帮助了我：

 const { headers: { authorization } } = req;
 const token = authorization && authorization.split(" ")[1];
