javascript - 获取 "TypeError: res.status is not a function."

Question

TypeError:res.status 不是函数
在 auth (D:\PROJECT\Web Application\Learning React\MERN STACK\middleware\auth.js:17:9)。
我收到此错误。代码如下。

const config = require("config");
const jwt = require("jsonwebtoken");

function auth(res, req, next) {
  const token = req.header("x-auth-token");

  // Check for token
  if (!token) res.status(401).json({ msg: "No token, authorization denied" });

  try {
    // verify token
    const decoded = jwt.verify(token, config.get("jwtSecret"));
    // Add user from payload
    req.user = decoded;
    next();
  } catch (e) {
    res.status(400).json({ msg: "Token is not valid" });
  }
}

module.exports = auth;

应该是 req, res, next改变

function auth(res, req, next) {

至

function auth(req, res, next) {
