Question

我正在Windows10中的Visual Studio 2019中的树莓派中运行服务器，当我运行调试时，它卡在send（）中。从树莓派运行。客户端是Windows10中的PC。

我已经搜索了互联网，并试图找到导致错误的原因，但没有找到答案。错误代码仅在调试中出现，并指出发送文件的地址不正确。它可以毫无问题地连接并接收来自客户端的消息。

void TCPServer::setup(int port)
{   
        int b = 0;
    int l = 0;
    sockfd = socket(AF_INET, SOCK_STREAM, 0);
    memset(&serverAddress, 0, sizeof(serverAddress));
    serverAddress.sin_family = AF_INET;
    serverAddress.sin_addr.s_addr = htonl(INADDR_ANY);
    serverAddress.sin_port = htons(port);
    b = bind(sockfd, (struct sockaddr*) & serverAddress, sizeof(serverAddress));
    if (b == -1) 
    {
        cout << "Error Binding - " << b << endl;
    }
    cout << "> bind: " << strerror(errno) << " / codigo: " << b << endl;
    l = listen(sockfd, 5);
    if (l == -1)
    {
        cout << "Error Listening - " << l << endl;
    }
    cout << "> listen: " << strerror(errno) << " / codigo: " << l << endl;
    std::cout << ">>> waiting for client" << endl;
    socklen_t sosize = sizeof(clientAddress);
    newsockfd = accept(sockfd, (struct sockaddr*) & clientAddress, &sosize);
    if (newsockfd == -1)
    {
        cout << "Error accepting - " << newsockfd << endl;
    }
    cout << "> accept: " << strerror(errno) << " / codigo: " << newsockfd << endl;
    std::cout << ">>> client accepted" << endl;
}

//在这里卡住了：

int TCPServer::Send(string msg)
{
    int bytesSend = 0;
    bytesSend = send(newsockfd, msg.c_str(), MAXPACKETSIZE, 0);
    cout << "> bytes sent " << bytesSend << "(" << strerror(errno) << "/" << inet_ntoa(clientAddress.sin_addr) << ")" << endl;

    return bytesSend;
}

调试模式下的输出为：bytes sent -1 (Bad address/192.168.137.1)

send is returning -1温德尔诺（Wend errno）提供了错误的地址

未经调试运行的输出为：Response to be sent: Hello! :) 1 bytes sent 2920(Success/192.168.137.1)

Visual Studio在“调试/发布”模式下停留在发送状态，但在标准模式下运行，“无需调试即可启动”
