thinkphp6实现JWT操作

首先安装JTW扩展

composer require firebase/php-jwt

首先封装一个类叫JWT

在里面添加如下代码

两个方法，一个为生成token  一个为检测token

 $userid,"iss" => env('TOKEN.iss'),//签发组织"aud" => env('TOKEN.aud'), //签发作者"iat" => $time,"nbf" => $time,"exp" => $expire);return JWTUtil::encode($token,$key);}/*** 验证token* @return \think\response\Json*/public static function verifyjwt($jwt){if(in_array($jwt,cache('delete_token'))){throw new Exception('token过期',"400");}$key = md5(env('TOKEN.key')); //jwt的签发密钥，验证token的时候需要用到try{$jwtAuth = json_encode(JWTUtil::decode($jwt,$key,array("HS256")));$authInfo = json_decode($jwtAuth,true);if (!$authInfo['user_id']){return \json(['code'=>400,'msg'=>"用户不存在",'data'=>[]]);}return \json(['code'=>200,'msg'=>"ok",'data'=>[]]);}catch (ExpiredException $e){return \json(['code'=>501,'msg'=>"token过期",'data'=>[]]);}catch (\Exception $e){return \json(['code'=>$e->getCode(),'msg'=>$e->getMessage(),'data'=>[]]);}}
