这篇CFSDN的博客文章Python实现基于TCP UDP协议的IPv4 IPv6模式客户端和服务端功能示例由作者收集整理,如果你对这篇文章有兴趣,记得点赞哟.

本文实例讲述了Python实现基于TCP UDP协议的IPv4 IPv6模式客户端和服务端功能。分享给大家供大家参考,具体如下:

由于目前工作的需要,需要在IPv4和IPv6两种网络模式下TCP和UDP的连接,要做到客户端发包,服务端收包.

前几天写了代码,但是把UDP的客户端和服务端使用TCP模式的代码了。今天在公司使用该工具的时候,发现了问题,忘记了UDP不需要验证。疏忽,疏忽。不过刚刚接触编程,可以原谅.

现在在家,已经把代码改好了。经测试可以使用.

先运行客户端:

?
1
python MiniClient.py host port mode(t4, t6, u4, u6)

再运行服务端:

?
1
python MiniServer.py host port mode(t4, t6, u4, u6)

客户端代码如下:
