thinkphp5 framework API token authentication function [example]

The following is the tutorial column of thinkphp to introduce [Example] thinkphp5 framework API token authentication function. I hope it will be helpful to friends in need!

Instructions for use: Generate token and refresh_token when logging in, and return them to the client. The client receives and saves local localStorage, etc., and brings the token every time it accesses the interface. The backend verifies that the token exists and is consistent before the next action can be performed. If it does not exist, it returns that the token has expired. The client calls the refresh interface and passes in the token and refresh_token. The server verifies, and the verification saves the database by regenerating a new token and returns Refresh local token access for the client to continue. When refresh_token verification fails, clear the database token, expiration time and other information

Simple token generation function (public function file common)

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

Verify login method (model)

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 refresh method (model)

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];
}

Exit method (model)

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');
}
