NodeJS Express.js JWT身份验证问题：用户令牌在本地存储中可用，但收到未验证的消息

我想提交一份评论。但是在我的verifyToken和verifyUser中间件中，我没有得到值。相反，它说的是值是未定义的，尽管我在控制台中获得了令牌和用户名。
由于我没有在中间件中获得用户信息和令牌，它说我没有授权，并阻止我提交审查。如果我将verifyToken和verifyUser中间件从审查路径中删除，那么它可以正常工作。但如果我添加了它们，那么在终端中会显示：

req.user: undefined

Token: undefined

虽然我在前端本地存储中获得令牌和用户。
我需要帮助来克服这个问题。感谢是预付款。
中间件：

const jwt = require("jsonwebtoken");

const verifyToken = (req, res, next) => {
  console.log("req.user:", req.user);
  console.log("req.params.tourId:", req.params.tourId);
  const token = req.cookies.accessToken;
  console.log("Token received in verifyToken:", token);
  console.log("Token:", token);

  if (!token) {
    return res.status(401).json({
      success: false,
      message: "You are not authorized",
    });
  }

  try {
    const user = jwt.verify(token, process.env.JWT_SECRET);
    console.log("Decoded User:", user);
    req.user = user;
    next();
  } catch (error) {
    console.error("Token Verification Error:", error);
    res.status(401).json({
      success: false,
      message: "Token is Invalid",
    });
  }
};

const verifyUser = (req, res, next) => {
  console.log("req.user:", req.user);
  console.log("req.params.tourId:", req.params.tourId);

  if (
    req.user &&
    (req.user.id === req.params.tourId || req.user.role === "admin")
  ) {
    next();
  } else {
    return res.status(401).json({
      success: false,
      message: "You're not authenticated",
    });
  }
};

const verifyAdmin = (req, res, next) => {
  if (req.user.role === "admin") {
    next();
  } else {
    return res.status(401).json({
      success: false,
      message: "You're not authorized",
    });
  }
};

module.exports = { verifyToken, verifyAdmin, verifyUser };

路线：

const express = require("express");
const router = express.Router();
const { verifyUser, verifyToken } = require("../utils/verifyToken");

const { createReview } = require("../controller/reviewController");

router.post("/:tourId", verifyToken, verifyUser, createReview);

module.exports = router;

控制器：

const Review = require("../model/Review");
const Tour = require("../model/Tour");

const createReview = async (req, res) => {
  const tourId = req.params.tourId;
  const newReview = new Review({ ...req.body });

  try {
    const savedReview = await newReview.save();

    await Tour.findOneAndUpdate(
      { _id: tourId },
      { $push: { reviews: savedReview._id } }
    );

    res.status(200).json({
      success: true,
      message: "Review Submitted",
      data: savedReview,
    });
  } catch (error) {
    res.status(500).json({
      success: false,
      message: error.message,
    });
    console.log(error);
  }
};

module.exports = { createReview };

看起来你在前端的Authorization头上发送访问令牌，但试图从verifyToken中间件函数中的cookie中读取。请记住，在您的axios请求配置对象中设置的withCredentials属性不会自动发送存储在localStorage对象中的数据，它只会发送为您当前浏览会话存储的相关cookie。只要在请求的Authorization头中发送了一个有效的会话jwt，下面的代码就可以帮助您通过验证。

const verifyToken = (req, res, next) => {
  const authHeader = req.get("Authorization")?.split(" ");

  if (!authHeader || authHeader[0] !== "Bearer" || !authHeader[1]) {
    return res.status(401).json({
      success: false,
      message: "You are not authorized",
    });
  }

  const token = authHeader[1];

  try {
    const user = jwt.verify(token, process.env.JWT_SECRET);
    req.user = user;        
    next();
  } catch (error) {
    console.error("Token Verification Error:", error);

    if(["JsonWebTokenError", "TokenExpiredError"].includes(error.name)) {
      return res.status(401).json({
        success: false,
        message: "Token is Invalid",
      });
    }

    res.status(500).json({
      success: false,
      message: "Internal Server Error",
    });
  }
};

字符串
原文回答：
我没有看到任何对verifyToken函数的调用，该函数应该设置req.user对象，所以看起来你需要替换：

router.post("/:tourId", verifyUser, createReview);

型
与：

router.post("/:tourId", verifyToken, verifyUser, createReview);

型
这将首先调用verifyToken，如果验证成功，它将设置req.user对象，然后调用下一个中间件函数，在本例中是verifyUser。
