Postman is stuck at a "GET" request, giving error that "Could not get response Error: read ECONNRESET" in Node JS using PostgreSQL as backend

Question

我正在观看有关使用 JWT 令牌进行登录身份验证的视频教程。

我在 PostgreSQL 上构建了一个数据库，将其连接到我的 Node JS 服务器并测试了注册和登录命令。这两个查询在 Postman 上运行良好，并且 Postman 返回了预期的结果。

现在，在登录时，我在返回值中得到了一个JWT Token，它将进一步用于获取登录的用户ID及其信息。

因此，为了测试该令牌是否有效，我制作了一条路线来验证用户是否已登录。（添加在登录和注册路由所在的同一个文件中）

此路由文件文件代码如下(jwAuth.js)。 我没有在里面添加注册码和登录码

const router = require('express').Router() 
const pool = require("../db")
const bcrypt = require("bcryptjs");
const jwtGenerator = require('../utils/jwtGenerator');
const authorization = require('../middleware/authorization');
// Registeration and Login Routes
// Verification Route 
router.get("/is-verify", authorization, async (res, req) => {
    try {
        res.json(true); 
        
    } catch (err) {
         console.log(err.message); 
        res.status(500).send("Server Error")
    }
})
module.exports = router;

中间件authorization.js的代码如下，

const jwt = require("jsonwebtoken");
require("dotenv").config();
module.exports = async (req, res, next) => {
    try {

        const jwtToken = req.header("token");

        if (!jwtToken) {
            return res.status(403).json("Not Authorized");
        }

        // In case we do have a token, check if the token is valid or not 
        const payload = jwt.verify(jwtToken, process.env.jwtSecret);

        req.user = payload.user; 


    } catch (err) {
        console.log(err.message); 
        return res.status(403).json("You are not authorized");
    }
}

我也在另一条路线上尝试了同样的事情，dashboard.js 应该 return/print 使用给它的 JWT 令牌的用户的 ID，条件是用户已正确登录

dashboard.js的代码如下,

const router = require('express').Router()
const pool = require("../db")
const authorization = require("../middleware/authorization")

router.get("/", authorization, async (req, res) => {
    try {
        res.json(req.user); 
    } catch (err) {
        console.log(err.message)
        res.status(500).json("Server Error"); 
    }
})


module.exports = router

而我的index.js（或server.js）的代码如下，

const express = require('express')
const app = express() 
const cors = require('cors')

app.use(express.json()) // Lets you use req.body 
app.use(cors())

// ROUTES 

// Register and Login Routes 

app.use("/auth", require("./routes/jwAuth"));
app.use("/dashboard", require("./routes/dashboard"));


app.listen(3000, () => {
    console.log("Console is running");
})

我的问题是，如果我尝试使用所需数据向以下链接发送请求，Postman 工作正常并且数据也添加到我的数据库中（并且在检查登录时也被正确检索）

http://localhost:3000/auth/register
http://localhost:3000/auth/login

但是当我用这个 URL 尝试同样的事情时（通过在邮递员 GET 请求的 Header 中提供 JWT 令牌，

http://localhost:3000/dashboard
http://localhost:3000/auth/is-verify

Postman 卡住了，处理请求的时间很长，最终报错，

无法得到回应错误：读取 ECONNRESET

我试着搜索这个错误，显然这个问题的解决方法是在 etc/hosts 文件中添加本地主机的 IP 地址，但在那种情况下，我的注册和login POST Requests 也不会起作用。我无法解决问题，请有人帮忙。

可以肯定的是，我还在 etc/hosts 文件下方共享了 Registration/Login 路由以及 jwtGenerator 文件

Answer 1

您忘记在您的身份验证中间件中调用 next，这将导致挂起请求。通过执行以下操作修复它：

module.exports = async (req, res, next) => {
    try {

        // ...       

        req.user = payload.user; 
        next();


    } catch (err) {
        console.log(err.message); 
        return res.status(403).json("You are not authorized");
    }
}
