I get this error:

Server.ts

    import * as express from 'express';
    import {Application} from "express";
    import * as fs from 'fs';
    import * as https from 'https';
    import {retrieveUserId} from './user-middleware-extraction';

    const bodyParser = require('body-parser');
    const cookieParser = require('cookie-parser');



const app: Application = express();
app.use(cookieParser());
app.use(retrieveUserId);
app.use(bodyParser.json());

` User-middleware-extraction.ts

import { NextFunction,Request,Response } from "express";
import { decodeToken } from "./security.utils";

export function retrieveUserId(res:Response,req:Request,next:NextFunction) {
    const jwt = req.cookies['SESSIONID']   // retrieving the jwtoken
    if(jwt) {
        handleSession(jwt, req)
      .then(()=>
      next())
      .catch(err=>
        {
            console.log(err);
            next()    
        })
    }
}

async function  handleSession(jwt, req) {
    try {
        req['userId'] = payload.sub//request contain the id
        var payload = await decodeToken(jwt)//payload of the jwt
    }
    catch(err) {
        console.log("error is", err)
    }
}

While assigning the middleware to server.ts this error is popping up. No idea what is causing this to happen.

Is the issue with the middleware functionality?

CodePudding user response：

Sorry, my bad. It seems like you just have to exchange req and res function parameters in order to get matching types.

Order of path params should be: (req, res, next). You switched up request and response params.
