tcp python socket client

接口测试遇到tcp socket server的测试，需要模拟socket client，发送各种格式包，接受server返回值验证正确性。

socket client代码

import socket

class TcpComm:

    def __init__(self, _ip , _port):
        self.send_addr = (_ip, _port)
        self.buffersize = 10240000
        self.comm_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.comm_socket.connect(self.send_addr)
        self.recv_from_addr=()


    def send(self,string_data):
        self.comm_socket.send(string_data)

    def recv(self):
        self.string_data = self.comm_socket.recv(self.buffersize)
        return self.string_data

    def __del__(self):
        self.comm_socket.close()
        self.client_socket.close()
_tcp_client = TcpComm("127.0.0.1",8866)
_tcp_client.send("client_hello_world")
string_data = _tcp_client.recv()
print "recv from:", string_data
