HTTPServer
阻塞IO与非阻塞IO
IO多路复用
select方案
位运算
poll方案

1. HTTPServer

#httpserver.py
#服务端 httpserver

from socket import *

#定义处理客户端请求函数
def handleClient(connfd):
	request = connfd.recv(4096)
	request_lines = request.splitlines()
	#bytes.splitlines()
	for line in request_lines:
		print(line.decode())
	try:
		f = open("index.html")
	except IOError :
		response = "HTTP/1.1 404 not found\r\n"
		response += "\r\n" #空行
		response += "====Sorry not found===="
	else:	#未发生异常执行Else
		response = "HTTP/1.1 200 OK\r\n"
		response += "\r\n" #空行
		response += f.read()
	finally:
		connfd.send(response.encode())	


def main():
	sockfd = socket()
	sockfd.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
	sockfd.bind(("0.0.0.0",8888))
	sockfd.listen(3)
	print("listen to the port 8888")
	while True:
		connfd, addr = sockfd.accept()
		#调用处理客户端请求函数,并返回响应
		handleClient(connfd)
		connfd.close()

if __name__ == "__main__":
	main()

index.html

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>Chrom</title>
</head>
<body>
	<h1>My HTML</h1>
</body>
</html>
