C++ Boost ASIO-无法通过TCP发送消息

我正在使用Boost ASIO进行TCP网络通信。这是我的密码：

以下是我如何模拟与服务器的几个连接：

Config config("AuthServer");
std::string defaultIP   = "127.0.0.1";
std::string defaultPort = "8080";
int connectionsNumber   = CommandQuestion<int>::AskQuestion("How many connections do you want established?");
std::cout << "Initializing " << std::to_string(connectionsNumber) << " connection/s." << std::endl;

std::cout << "Trying to connect to  " <<  defaultIP << " on port: " << config.GetConfigValue("AuthServerPort", defaultPort)  << std::endl;
boost::asio::io_context io_context;
std::vector<tcp::socket> sockets;
for (int i = 0; i < connectionsNumber; ++i) {
    try
    {
        sockets.emplace_back(io_context);
        tcp::socket& s{sockets.back()};
        tcp::resolver resolver(io_context);
        boost::asio::connect(s, resolver.resolve( defaultIP,config.GetConfigValue("AuthServerPort", defaultPort)));

        std::string message = "I am testing here!!!";
        size_t request_length = std::strlen(message.c_str());
        boost::asio::write(s, boost::asio::buffer(message, request_length));

        char reply[max_length];
        size_t reply_length = boost::asio::read(s,boost::asio::buffer(reply, request_length));
        Logger::Log(std::to_string(i) + " Connected!",Logger::Success);
                std::cout << "Reply is: ";
                std::cout.write(reply, reply_length);
                std::cout << "\n";
    }
    catch (std::exception& e)
    {
        std::cerr << "Exception: " << e.what() << "\n";
    }

Config配置（“AuthServer”）；
std:：string defaultIP=“127.0.0.1”；
std:：string defaultPort=“8080”；
int connectionsNumber=CommandQuestion:：AskQuestion（“您希望建立多少个连接？”）；
std：：cout我发现了错误所在，下面是我解决问题的方法：

void Vibranium::Client::Send(ServerOpcode serverOpcode, const std::string& message) {
    auto self(shared_from_this());
    std::cout << "HERE!" << std::endl;
    strcpy(data_, message.c_str());
    size_t request_length = sizeof(data_)/sizeof(*data_);
    boost::asio::async_write(socket, boost::asio::buffer(data_, request_length),
     [this, self](boost::system::error_code ec, std::size_t /*length*/)
     {
         if (ec)
             Logger::Log("Message sent failed to " + std::to_string(connectionId),Logger::Error);
     });
}

void Vibranium:：Client:：Send（ServerOpcode ServerOpcode，const std:：string&message）{
自动自我（从_this（）共享_）；
std:：cout不确定，但
async_write（socket，boost:：asio:：buffer（message.c_str（），…
in
Vibranium:：Client:：Send
看起来可疑。message.c_str（）返回的以null结尾的字符串
可能在
异步写入
完成之前变得无效。从有关
缓冲区
参数的文档中：
“…调用方保留底层内存块的所有权，这必须保证它们在调用处理程序之前保持有效。”
