python写一个简单程序作为服务器，浏览器通过IP和端口访问，进行交互

#浏览器------>服务器发送数据格式如下：
#   GET / HTTP/1.1
#   Host: 127.0.0.1:8080
#   Connection: keep-alive
#   Upgrade-Insecure-Requests: 1
#   User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3724.8 Safari/537.36
#   Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3
#   Accept-Encoding: gzip, deflate
#   Accept-Language: zh-CN,zh;q=0.9,und;q=0.8


#服务器------->浏览器回送的数据.....
print("写一个服务器，用浏览器访问")
# import socket
#
# def service_client(new_socket):
#     #1、接收浏览器发过来的数，即http请求
#     #GET / HTTP/1.1
#     #.....
#     request = new_socket.recv(1024)
#     print(request)
#     #2、返回HTTP格式数据，给浏览器
#     #2.1准备发送给浏览器的数据-----header
#     response = "HTTP/1.1 200 OK\r\n"
#     response += "\r\n"
#     #2.2准备发送发给浏览器的数据-----boy
#     response +="
hahahahhah
"
#     new_socket.send(response.encode("utf-8"))
#     #关闭套接字
#     new_socket.close()
#
# def main():
#     """"整体控制"""
#     #1、创建套接字
#     tcp_server_socket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
#     #2、绑定
#     tcp_server_socket.bind("127.0.0.1",7890)
#     #3、变为监听套接字
#     tcp_server_socket.listen(128)
#     while True:
#         #4、等待客户端的链接
#         new_socket,client_addr = tcp_server_socket.accept()
#         #5、为客户端服务
#         service_client(new_socket)
#     #关闭监听套接字
#     tcp_server_socket.close()
#
# if __name__ =="__main__":
#     main()
print("")
