JWT Token (Invalid token Specified)

Question

I have module to check if the expiration date of token is already expired or not. so if ever the token is expired it will automatically the page will go to login again.

I already code it but their is error in my console and my page is loading anymore.

Uncaught InvalidTokenError {message: "Invalid token specified"}

List not working

• I read some post it says need to put this. { header: true }
• Need specify if the localstorage has token

This is my code:

        if (localStorage.getItem("token") === null) {
        let token_expired = localStorage.getItem('token');
        let decoded = decode(token_expired, { header: true });
        let decode_string = decoded["exp"];
        var current_time = Date.now() / 1000;
        if(decode_string < current_time)
        {
            localStorage.clear();
        }
    }

Answer 1

I think that your token does not exist.

1. Go inside dev tools (ctrl +shift + i) then

2. Select Application

3. Inside the Application go to Storage then

4. Open Local Storage (double click on local storage) then

5. Clear local storage

Answer 2

I think you need to change the first condition, and use declarative names for variables.

const storedToken = localStorage.getItem("token");
if (storedToken){
   let decodedData = decode(storedToken, { header: true });
   let expirationDate = decodedData.exp;
    var current_time = Date.now() / 1000;
    if(expirationDate < current_time)
    {
        localStorage.removeItem("token");
    }
 }
