[英]NodeJS/Express - Cannot Read All Req.Headers
Building a simple ToDo app with ReactJs frontend and NodeJs/Express backend.使用 ReactJs 前端和 NodeJs/Express 后端构建一个简单的 ToDo 应用程序。 I configured my frontend to include userId as a request header:
我将我的前端配置为包含 userId 作为请求 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-end
return {
'x-access-token': user.accessToken,
'userid': user.id
}; // for Node.js Express back-end
} else {
return {};
}
}
This header is included with the Axios request:这个 header 包含在 Axios 请求中:
// List all Group Members
listMembers() {
return http.get(`/group`, { headers: authHeader() });
}
Consequently, I can see the headers in the request:因此,我可以在请求中看到标头:
Part of my auth middleware references the access token: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: "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.顶部附近的 req.headers 行能够毫无问题地从 header“x-access-token”中提取令牌。 HOWEVER - for debug purposes, I have tried to pull the header userId value instead using let token = req.headers["userid"];
但是 - 出于调试目的,我尝试拉取 header userId 值,而不是使用let token = req.headers["userid"]; but this simply comes back as undefined in my debug tools.
但这只是在我的调试工具中返回为未定义。 Why can it pull x-access token header but not userId?
为什么它可以拉取 x-access token header 而不是 userId? My eventual goal is to refer to the req.header userId value in backend SQL queries, this is just a test.
我最终的目标是在后端SQL查询中引用req.header userId值,这只是一个测试。
It ended being a capitalization error somewhere in pipeline.它最终成为管道中某处的大写错误。 @Sardar's comment was on the money, make sure everything is spelled correctly and matches case.
