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 OKrn"
  response_headers = "Server: My serverrn"
  response_body = "hello itcast"
  response = response_start_line + response_headers + "rn" + 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：

[127.0.0.1, 50066]用户连接上了
