Jwt

A simple jwt

⚙ Installation

go get -u github.com/eininst/go-jwt

Create a token

package main

import (
    "fmt"
    "github.com/eininst/go-jwt"
    "time"
)

func main() {
    j := jwt.New("m9561kcc59534db1203e6572f7d5dq1x")

    data := map[string]interface{}{
        "id":   123,
        "name": "wzq",
    }

    token := j.CreateToken(data, time.Second*10)
    fmt.Println("Create a token:", token)
}

Parse a token

func main() {
    var ps map[string]interface{}
    
    er := j.ParseToken(token, &ps)
    
    if errors.Is(er, jwt.Expired) {
        fmt.Println("my is expired")
        return
    }
    
    fmt.Println("Parse a token:", ps)
}
