本文实例讲述了thinkphp5框架API token身份验证功能。分享给大家供大家参考,具体如下:
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');
}
