My middle tear code is not giving expected output

const verifyJWT = (req, res, next) => {
  // console.log('jwt');
  const authHeader = req.headers.authorization;
  if (!authHeader) {
    return res.status(401).send({ message: "Unauthotized access!" });
  }
  const token = authHeader.split(" ")[1];
  console.log(token)
  jwt.verify(token, process.env.ACCESS_TOKEN_SECRET, function (err, decoded) {
    if (err) {
      return res.status(403).send({ message: "Forbidden access!" });
    }
    // console.log(decoded);
    req.decoded = decoded;
    // console.log(req.decoded.email, "decod");
    next();
    console.log('decoded',req.decoded);
  });
};

Below lines of code gives the token properly const token = authHeader.split(" ")[1]; console.log(token)

But Decoding is not working properly. It's provide error and not decoding. It

jwt.verify(token, process.env.ACCESS_TOKEN_SECRET, function (err, decoded) {
    if (err) {
      return res.status(403).send({ message: "Forbidden access!" });
    }
    // console.log(decoded);
    req.decoded = decoded;
    // console.log(req.decoded.email, "decod");
    next();
    console.log('decoded',req.decoded);
  });

 console.log('decoded',req.decoded); gives output decoded { email: '[object Object]', iat: 1655887103, exp: 1655890703 }

CodePudding user response：

You have to assign string to the email. Debug the method that creates jwt token. Here is my method:

import jwt from 'jsonwebtoken'
const generateJwtToken = (email:string): string => {
    const token = jwt.sign({ email: email }, jwtKey)
    return token
}

CodePudding user response：

useEffect(()=>{
        const email = user?.user?.email;
        const currentUser = {email:email};
        console.log(currentUser,'hfghfh')
        if(email){

            fetch(`http://localhost:5000/user/${currentUser.email}`,{
                method: 'PUT',
                headers: {
                    'content-type': 'application/json'
                },
                body:JSON.stringify(currentUser)
            })
            .then(res=>res.json())
            .then(data=>{
                console.log(data);
                const accessToken = data.token;
                localStorage.setItem('accessToken',accessToken);
                setToken(accessToken);
            })
        }
    },[user])

In my frontend code I made a mistake. I am passing and object thorough email and didn't extract the email value. Insepect of passing currentUser.email fetch(http://localhost:5000/user/${currentUser.email} I was passing just currentUser.

Thanks everyone for helping me for this problem.
