thinkphp5框架API token身份验证功能【示例】

使用说明:登陆时生成token和刷新用的refresh_token,返回给客户端,客户端收到保存本地localStorage等,每次访问接口带上token,后端验证token存在并且一致后方可执行接下来的动作,假如不存在就返回token过期,客户端调用刷新接口传入token和refresh_token,服务器端进行验证,验证通过重新生成新的token保存数据库,返回给客户端客户端刷新本地token访问即可继续,当refresh_token验证失败就清除数据库token,过期时间等信息

简单的token生成函数(公共函数文件common)

function create_token($id,$out_time){   return substr(md5($id.$out_time),5,26); }

验证登陆方法(模型)

public function checkLogin($username,$passwd){     $driver = self::field('driver_id,passwd')->where('zhanghao',$username)->whereOr('phone',$username)->find();     if (empty($driver)){       $this->error = '账号不存在';       return false;     }     if ($driver['passwd'] != md5($passwd)){       $this->error = "密码不正确";       return false;     }     //$out_time = strtotime('+ 1 days');     $out_time = strtotime('+ 1 minutes');     $token = create_token($driver['driver_id'],$out_time);     if(false===self::save(['token'=>$token,'time_out'=>$out_time],['driver_id'=>$driver['driver_id']])){       $this->error = '登陆失败';       return false;     }     $refresh_token_out_time = strtotime('+ 5 days');     $refresh_token = create_token($driver['driver_id'],$refresh_token_out_time);     Cache::set("token",$token,60);     Cache::set("driver_id",$driver['driver_id'],$refresh_token_out_time);//设置ID的过期时间和更新token的token时间一样用于更新的时候获取用户信息     Cache::set('refresh_token',$refresh_token,$refresh_token_out_time);     return ['token'=>$token,'refresh_token'=>$refresh_token,'in_expire'=>$out_time]; }

token刷新方法(模型)

public function refreshToken($refresh_token,$token){     if (!isset(Cache::get('refresh_token')) or Cache::get('refresh_token')!=$refresh_token){       $this->error = '刷新token失败';       return false;     }     $cache_driver_id = Cache::get('driver_id');     $driver = self::field('driver_id,passwd')->where('driver_id',$cache_driver_id)->where('token',$token)->find();     if (empty($driver)){       $this->error = '参数错误';       return false;     }     $out_time = strtotime('+ 1 days');//新的过期时间     $token = create_token($driver['driver_id'],$out_time);//更新token     if(false===self::save(['token'=>$token,'time_out'=>$out_time],['driver_id'=>$driver['driver_id']])){       Cache::clear($token);       $this->error = '刷新失败';       return false;     }     Cache::set("token",$token,864000);     return ['token'=>$token,'in_expire'=>$out_time]; }

退出方法(模型)

public function logout($token,$refresh_token=''){     $driver = self::field('driver_id,passwd')->where('token',$token)->find();     self::save(['token'=>'','time_out'=>''],['token'=>$token]);     Cache::clear('token');     Cache::clear('refresh_token'); }
