本文实例讲述了ThinkPHP5框架中使用JWT的方法。分享给大家供大家参考，具体如下：

JWT下载地址：https://jwt.io

可以直接去github上下载，也可以使用composer

使用composer的话要确保你的电脑上安装了composer，进入项目根目录下载即了，自动会放在vendor目录下

创建文件

我是放在common目录下

使用教程

github都有的

贴源码

JWTAuth.php

<?php
namespace app\common\Auth;
use \Lcobucci\JWT\Builder;
use \Lcobucci\JWT\Signer\Hmac\Sha256;
use \Lcobucci\JWT\Parser;
use \Lcobucci\JWT\ValidationData;
/**
 * 单例模式
 */
class JWTAuth
{
    private static $instance;
    /**
     * JWT TOKEN
     * @var [type]
     */
    private $token;
    /**
     * 颁发
     * @var string
     */
    private $iss = 'api.test.com';
    /**
     * 接收
     * @var string
     */
    private $aud = 'app.com';
 
    private $uid;
 
    private $secrect="#$%#$%*&^(*(*(";
 
    private $decodeToken;
 
    public static function getInstance() {
        if(is_null(self::$instance)) {
            self::$instance = new self();
        }
        return self::$instance;
    }
 
    private function __contruct(){
 
    }
 
    private function __clone(){
 
    }
 
    public function encode(){
        $time = time();
        $this- token = (new builder())- setHeader('alg','HS256')
            - setIssuer($this- iss)
            - setAudience($this- aud)
            - setIssuedAt($time) //生效时间
            - setExpiration($time + 20)//过期时间
            - set('uid',$this- uid)
            - sign(new Sha256(), $this- secrect)//加密算法
            - getToken();
 
            return $this;
    }
 
    public function getToken(){
        return (string)$this- token;
    }
 
    public function setToken($token){
        $this- token = $token;
        return $this;
    }
    /**
     * 用户信息uid
     * @param [type] $uid [description]
     */
    public function setUid($uid){
        $this- uid = $uid;
        return $this;
    }
 
    public function jsonDecode(){
 
        $token = $this- token;
        $this- decodeToken = (new Parser())- parse((string) $token); 
 
        // echo $this- decodeToken- getClaim('uid');
        return $this- decodeToken;
    }
    /**
     * 验证令牌是否有效
     * @return [type] [description]
     */
    public function validate(){
 
        $data = new ValidationData();
        $data- setIssuer($this- iss);
        $data- setAudience($this- aud);
        return $this- jsonDecode()- validate($data);
 
    }
    /**
     * 签名来验证令牌在生成后是否未被修改
     * @return [type] [description]
     */
    public function verify(){
        $result = $this- jsonDecode()- verify(new Sha256(), $this- secrect);
        return $result;
    }
 
}

user.php 用来测试

<?php
namespace app\index\controller;
use app\common\Auth\JWTAuth;
 
class User{
 
    public function login(){
        
        $jwtAuth = JWTAuth::getInstance();
        $token = $jwtAuth- setUid(1)- encode()- getToken();
        echo $token;
        // var_dump(success_json_data(['token'= $token]));
    }
 
    public function check_login(){
        $jwtAuth = JWTAuth::getInstance();
        $jwtAuth- setToken('eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJhcGkudGVzdC5jb20iLCJhdWQiOiJhcHAuY29tIiwiaWF0IjoxNTU2MDk1MDI5LCJleHAiOjE1NTYwOTUwNDksInVpZCI6MX0.oi4rLbQFNZUJsW4fVHWiOQxfEmomuvldAV-gFKl2V74');
 
        if($jwtAuth- validate() && $jwtAuth- verify()){
            echo '验证成功';
        }else{
            echo '登录过期';
        }
 
    }
}
