python之多并发socket（zz)

import socketserver

# socketserver有四个基本的类,后两个不常用，这4个类处理并发请求都是同步的，他们其实不是多线程的，

# 他们只是把socke封装了一下，加了一些方法，这里还没有实现多并发和多线程

# 这些方法不适用每个请求都耗费长时间才能完成

# socketserver.TCPServer

# socketserver.UDPServer

# socketserver.UnixStreamServer

# socketserver.UnixDatagramServer

# socketserver.ForkingMixIn

# socketserver.ThreadingMixIn

# ========================================================================================================

# 我们真正要用的下面这4个方法

# 多进程的socketserver

# socketserver.ForkingTCPServer

# socketserver.ForkingUDPServer

# 多进程的socketserver

# socketserver.ThreadingTCPServer

# socketserver.ThreadingUDPServer

# ========================================================================================================
