Go JWT Authorization in Go Creating a token using a custom claims type
Example
The StandardClaim is embedded in the custom type to allow for easy encoding, parsing and validation of standard claims.
tokenString := "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmb28iOiJiYXIiLCJleHAiOjE1MDAwLCJpc3MiOiJ0ZXN0In0.HE7fK0xOQwFEr4WDgRWj4teRPZ6i3GLwD5YCm6Pwu_c"
type MyCustomClaims struct {
Foo string `json:"foo"`
jwt.StandardClaims
}
// sample token is expired. override time so it parses as valid
at(time.Unix(0, 0), func() {
token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, func(token *jwt.Token) (interface{}, error) {
return []byte("AllYourBase"), nil
})
if claims, ok := token.Claims.(*MyCustomClaims); ok && token.Valid {
fmt.Printf("%v %v", claims.Foo, claims.StandardClaims.ExpiresAt)
} else {
fmt.Println(err)
}
})
Output:
bar 15000
