如何解码JSON Web Token中的签名部分

import jwt

def decode_jwt(token):
    header = jwt.get_unverified_header(token)
    payload = jwt.decode(token, verify=False)
    signature = jwt.decode(token, verify=False, options={"verify_signature": False})
    return signature

token = "your_jwt_token"
signature = decode_jwt(token)
print(signature)

const jwt = require('jsonwebtoken');

function decodeJWT(token) {
    const header = jwt.decode(token, { complete: true }).header;
    const payload = jwt.decode(token);
    const signature = token.split('.')[2];
    return signature;
}

const token = "your_jwt_token";
const signature = decodeJWT(token);
console.log(signature);
