jwt实现

<?phpnamespace app\admin\controller;

use think\Config;use think\Controller;use think\Request;use think\cache\driver\Redis;

/** * Class Base * @package app\admin\controller */class Base extends Controller{    /**     * Base constructor.     * @param Request|null $request     */    public function __construct(Request $request = null)    {        not_region(true);//允许        parent::__construct($request);    }

static function getAdminKey()    {        $admin_key = Config::get(‘key‘)["admin_key"];        return $admin_key;    }

/**     * @var     */    protected $head;

/**     * @var     */    protected $payload;

}

实现：

<?phpnamespace app\admin\controller;

use think\cache\driver\Redis;

/** * Class Index * @package app\admin\controller */class Index extends Base{    public function index(Redis $redis)    {        $token = $this::base64_meger($this->head(),$this->payload(2),$redis);        return $token;    }}

输出：
