使用python 写一个静态服务(实战)

师父布置的任务，让我写一个服务练练手，搞清楚socket的原理和过程后跑了一个小demo，很有成就感，代码内容也比较清晰易懂，很有教育启发意义。

代码

# coding:utf-8
import socket
from multiprocessing import Process

HTML_ROOT_DIR = ""

def handle_client(client_socket):
 """处理客户端请求"""
 # 获取客户端请求数据
 request_data = client_socket.recv(1024)
 print("request data:", request_data)

# 构造响应数据
 response_start_line = "HTTP/1.1 200 OK\r\n"
 response_headers = "Server: My server\r\n"
 response_body = "hello itcast"
 response = response_start_line + response_headers + "\r\n" + response_body
 print("response data:", response)

# 向客户端返回响应数据
 client_socket.send(bytes(response, "utf-8"))

# 关闭客户端连接
 client_socket.close()

if __name__=="__main__":
 server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 server_socket.bind(("", 8000))
 server_socket.listen(120)

while True:
   client_socket, client_address = server_socket.accept()
   # print("[％s, ％s]用户连接上了"％client_addrest[0],client_address[1])
   print("[％s, ％s]用户连接上了" ％ client_address)
   handle_client_process = Process(target=handle_client, args=(client_socket,))
   handle_client_process.start()
   client_socket.close()

运行后在浏览器输入：127.0.0.1:8000

http页面显示如下：

控制台输出：
