使用python 写一个静态服务(实战)

今天小编就为大家分享一篇使用python 写一个静态服务(实战)，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

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：
