基于boost1.60，写一个tcp通信的客户端

以下是基于boost1.60写的一个简单的TCP客户端示例代码。请注意，这只是一个示例，您需要根据您的具体需求进行修改和调整。

#include <iostream>
#include <boost/asio.hpp>

using boost::asio::ip::tcp;

int main(int argc, char* argv[])
{
    try
    {
        if (argc != 3)
        {
            std::cerr << "Usage: tcp_client <host> <port>\n";
            return 1;
        }

        boost::asio::io_service io_service;

        tcp::resolver resolver(io_service);
        tcp::resolver::query query(argv[1], argv[2]);
        tcp::resolver::iterator endpoint_iterator = resolver.resolve(query);

        tcp::socket socket(io_service);
        boost::asio::connect(socket, endpoint_iterator);

        std::cout << "Connected to " << argv[1] << ":" << argv[2] << std::endl;

        // 发送消息
        std::string message = "Hello, world!";
        boost::asio::write(socket, boost::asio::buffer(message));

        // 接收响应
        boost::asio::streambuf receive_buffer;
        boost::asio::read(socket, receive_buffer, boost::asio::transfer_all());

        // 处理响应
        std::string response = boost::asio::buffer_cast<const char*>(receive_buffer.data());
        std::cout << "Received response: " << response << std::endl;
    }
    catch (std::exception& e)
    {
        std::cerr << "Exception: " << e.what() << std::endl;
    }

    return 0;
}

使用时，您需要将`<host>`和`<port>`替换为您要连接的服务器的主机名和端口号。如果需要，您还需要根据您的实际情况修改发送和接收的消息。
