PS这个方法有一个缺点就是对端口数据全部拦截。我想偶尔放过几个封包，还有怎么拦截服务器返回的封包并修改。这个如果谁会了就无敌了。谁能教我改进下 感激不禁。-PS This method has the disadvantage that all the data on the port blocking. I would like to occasionally miss a few packets, and how to intercept and modify packets returned by the server. Who was on this if invincible. Who taught me to appreciate not help improve the next.
