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
