NodeJS/Express - Cannot Read All Req.Headers
问题
使用ReactJs前端和NodeJs/Express后端构建一个简单的ToDo应用程序。我配置了前端以将userId包含为请求头：
export default function authHeader() {const user = JSON.parse(localStorage.getItem('user'));if (user && user.accessToken) {// return { Authorization: 'Bearer ' + user.accessToken }; // 用于Spring Boot后端return {'x-access-token': user.accessToken,'userid': user.id}; // 用于Node.js Express后端} else {return {};}}
这个头部随着Axios请求一起被包含：
// 列出所有群组成员listMembers() {return http.get(`/group`, { headers: authHeader() });}
因此，我可以在请求中看到这些头部：
我的身份验证中间件的一部分引用了访问令牌：
verifyToken = (req, res, next) => {let token = req.headers["x-access-token"];if (!token) {return res.status(403).send({message: "未提供令牌！"});}jwt.verify(token, config.secret, (err, decoded) => {if (err) {return res.status(401).send({message: "未经授权！"});}req.userId = decoded.id;next();});};
顶部的req.headers行可以轻松地从头部"“x-access-token”中提取令牌。然而，出于调试目的，我尝试提取头部userId值，使用let token = req.headers["userid"];，但在我的调试工具中它只是返回未定义。为什么它能够提取"x-access-token"头部，但不能提取userId？我的最终目标是在后端SQL查询中引用req.header userId值，这只是一个测试。

Building a simple ToDo app with ReactJs frontend and NodeJs/Express backend. I configured my frontend to include userId as a request header:
export default function authHeader() {const user = JSON.parse(localStorage.getItem('user'));if (user && user.accessToken) {// return { Authorization: 'Bearer ' + user.accessToken }; // for Spring Boot back-endreturn {'x-access-token': user.accessToken,'userid': user.id}; // for Node.js Express back-end} else {return {};}}
This header is included with the Axios request:
// List all Group MemberslistMembers() {return http.get(`/group`, { headers: authHeader() });}
Consequently, I can see the headers in the request:
Part of my auth middleware references the access token:
verifyToken = (req, res, next) => {let token = req.headers["x-access-token"];if (!token) {return res.status(403).send({message: "No token provided!"});}jwt.verify(token, config.secret, (err, decoded) => {if (err) {return res.status(401).send({message: "Unauthorized!"});}req.userId = decoded.id;next();});};
The req.headers lines near the top is able to pull the token from header "x-access-token" with no problem. HOWEVER - for debug purposes, I have tried to pull the header userId value instead using let token = req.headers["userid"]; but this simply comes back as undefined in my debug tools. Why can it pull x-access token header but not userId? My eventual goal is to refer to the req.header userId value in backend SQL queries, this is just a test.
