http与tcp

浏览器请求

GET /   HTTP/1.1

服务器响应

1.     header

HTTP/1.1 200 OK

2.    body

<h1>hahhh</h1>

# 用python写服务端等待浏览器的请求，给一个简单的响应

import socket

def service_client(new_socket):

    request = new_socker.recv(1024)

    print(request)

    response = "HTTP/1.1 200 OK\r\n"

    response += "\r\n"

    response += "hahaahh"

    

    new_socket.send(response.encode("utf-8"))

    

    new_socket.close()

def main():

  tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

tcp_server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

    tcp_server_socket.bind("", 7890)

    tcp_server_socket.listen(128)

    

    while True:

        new_socket, client_addr = tcp_server_socket.accept()

        service_client(new_socket)

    tcp_server_socket.close()

if __name__ == "__main__":

    main()

服务器先调close先关，要等待2min

不用换端口，加

SO_REUSEADDR，就不用再等待2min

客户端不绑定端口，先关，换端口不用等待
