jwt 的下载无需复制博客和博客园

1：浏览器输入jwt 官网

官方地址

https://jwt.io/introduction

2：复制composer 命令

 composer require firebase/php-jwt

3：文件下载目录

（1）laravel 下载的文件位置

（2）：tp文件位置

4：文件新建一个service 目录，新建一个TokenService,进行创建方法名称

<?php


namespace App\service;



class TokenService
{

    /**
     *
     * 创建token
     */
    public function createToken(){

    }

    /**
     *
     * 验证token
     */
    public function  checkToken(){

    }
}

5：参看MD README.md 进行复制修改为以下的代码，创建token的加入用户id的形参。

<?php


namespace App\service;

// 第一步引入token
use Firebase\JWT\JWT;
use Firebase\JWT\Key;


class TokenService
{

    /**
     *
     * 创建token
     */


    public function createToken($userId){

        $key = "example_key";
        $payload = array(
            "iss" => "http://example.org",
            "aud" => "http://example.com",
            "iat" => 1356999524,
            "nbf" => 1357000000,
            "user_id"=>$userId
        );

        /**
         * IMPORTANT:
         * You must specify supported algorithms for your application. See
         * https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40
         * for a list of spec-compliant algorithms.
         */
        $token = JWT::encode($payload, $key, 'HS256');
//        $decoded = JWT::decode($jwt, new Key($key, 'HS256'));
        return $token;
    }

    /**
     *
     * 验证token
     */
    public function  checkToken($token){

        $key = "example_key";
        $payload = array(
            "iss" => "http://example.org",
            "aud" => "http://example.com",
            "iat" => 1356999524,
            "nbf" => 1357000000
        );

        /**
         * IMPORTANT:
         * You must specify supported algorithms for your application. See
         * https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40
         * for a list of spec-compliant algorithms.
         */
//        $token = JWT::encode($payload, $key, 'HS256');
    $decoded = JWT::decode($token, new Key($key, 'HS256'));
    return $decoded;

    }
}
