python-10-socket发送http协议来请求

1.模拟客户端（http协议拼接请求报文并发送）

    import socket
    client_socket=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
    client_socket.connect(('192.168.43.239',8080))
   
    file_path=input('请输入要请求的文件地址')
    
    request_line='GET ./%s HTTP/1.1\r\n'%file_path            #请求行
    request_header='Host=www.111.com\r\n'                     #请求头
    request_blank='\r\n'                                      #请求空行
    request_data=request_line+request_header+request_blank    #拼接请求报文
    
    client_socket.send(request_data.encode())
    content=client_socket.recv(40960).decode()
  
    if not content:                                           #没有响应主体，说明接收文件失败
        print('接收文件失败')
    else:
        print('正在接收服务端返回信息')
        with open('5.html','w')as file:
            loc=content.find('\r\n\r\n')
            body=content[loc+4:]
            file.write(body)
            print('已经保存信息')
    
    client_socket.close()

2.服务端

  import socket
    import time
    class Server():
        def __init__(self):                                                              #初始化                    
            tcp_server_socket=socket.socket(socket.AF_INET,socket.SOCK_STREAM)           #创建套接字
            tcp_server_socket.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,True)     #设置地址重用
            tcp_server_socket.bind(('192.168.43.239',8080))                              #绑定端口
            tcp_server_socket.listen(128)                                                #设置监听
            self.tcp_server_socket=tcp_server_socket                                     #其他函数需要用到的实例属性
       
        def addbaowen(self,reponse_body):                                                #拼接HTTP响应报文      
            reponse_line='HTTP/1.1 200 OK \r\n'
            reponse_headle='SERVER=BWC/1.0\r\n'
            reponse_blank='\r\n'
            reponse_data=(reponse_line+reponse_headle+reponse_blank+reponse_body).encode()
            return  reponse_data
        
        def start(self):

                    loc=request_data.find('\r\n')
                    request_list=request_data[:loc].split(' ')
                    file_path=request_list[1]
                    if file_path=='./':                                                  #判断客户端是否输入了目录资源地址，没输入则默认资源地址

                        reponse_data=self.handle(file_path)
                        new_client_soket.send(reponse_data)
                    except Exception as e:
                        print('对方发来的文件地址有误')
                        return
                    print('文件已经成功发送完毕')
                else:                                                                    #客户端断开连接，关闭套接字
