Token has invalid claims: token is expired

[maheshkumar2150]

How do i exactly look for the error?

What does it mean that token has invalid claims?

If the token has just expired, i would like to issue a new token. But it has invalid key or anything else, i cant issue a new token.

How do i check for errors?
Please give me an example

Thanks..

I am not 100 % sure, if I understand your problem correctly, but if you are looking for a way to differentiate between different error messages coming from the parser, you can have a look at our examples:

jwt/example_test.go

Lines 164 to 189 in 4d0edcd

	// An example of parsing the error types using errors.Is.
	func ExampleParse_errorChecking() {
	// Token from another example. This token is expired
	var tokenString = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmb28iOiJiYXIiLCJleHAiOjE1MDAwLCJpc3MiOiJ0ZXN0In0.HE7fK0xOQwFEr4WDgRWj4teRPZ6i3GLwD5YCm6Pwu_c"
	token, err := jwt.Parse(tokenString, func(token *jwt.Token) (interface{}, error) {
	return []byte("AllYourBase"), nil
	})
	switch {
	case token.Valid:
	fmt.Println("You look nice today")
	case errors.Is(err, jwt.ErrTokenMalformed):
	fmt.Println("That's not even a token")
	case errors.Is(err, jwt.ErrTokenSignatureInvalid):
	// Invalid signature
	fmt.Println("Invalid signature")
	case errors.Is(err, jwt.ErrTokenExpired) || errors.Is(err, jwt.ErrTokenNotValidYet):
	// Token is either expired or not active yet
	fmt.Println("Timing is everything")
	default:
	fmt.Println("Couldn't handle this token:", err)
	}
	// Output: Timing is everything
	}

Basically, you can use errors.Is to check for the different error types.
