Question

我正在创建一个套接字。它很容易第一次工作然后我停止套接字并重新生成它给我错误

class MainServer{
private:
    SOCKET soo;
public:
    // I have Basically Created Server Socket in this Function
    // And passed it
    SOCKET socket_control_mob(){
        struct sockaddr_in server;
        WSADATA wsa;

        printf("\nInitialising Winsock...");
        if (WSAStartup(MAKEWORD(2, 2), &wsa) != 0)
        {
            printf("Failed. Error Code : %d", WSAGetLastError());
            MessageBox(NULL, TEXT("Failed"), L"Failed", NULL);
            soo = NULL;
            return soo;
        }

        printf("Initialised.\n");
        //MessageBox(NULL, TEXT("Initialised"), L"Simple Message", NULL);
        //Create a socket
        if ((soo = socket(AF_INET, SOCK_STREAM, 0)) == INVALID_SOCKET)
        {
            printf("Could not create socket : %d", WSAGetLastError());
            MessageBox(NULL, TEXT("Socket Not Created1"), L"Failed", NULL);
            soo = NULL;
            return soo;
        }
        printf("Socket created.\n");

        //Prepare the sockaddr_in structure
        server.sin_family = AF_INET;
        server.sin_addr.s_addr = INADDR_ANY;
        server.sin_port = htons(8890);

        //Bind
        if (bind(soo, (struct sockaddr *)&server, sizeof(server)) == SOCKET_ERROR)
        {
            printf("Bind failed with error code : %d", WSAGetLastError());
            MessageBox(NULL, TEXT("Binding Error"), L"Failed", NULL);
            soo = NULL;
            return soo;
        }

        puts("Bind done");
        //MessageBox(NULL, TEXT("Bind Done"), L"Simple Message", NULL);

        return soo;
    }
    bool server_close_socket(){
            closesocket(soo);
            WSACleanup();
            return true;
    }
};

我通过调用

创建了一个套接字

MainServer s;
s.socket_control_mob()

我已经通过

停止了套接字

s.server_close_socket()

停止后不会创建套接字

您正在错误处理套接字，甚至是WinSock库本身。尝试更像这样的东西：

NoAnnotationError {message: "Cannot resolve all parameters for CustomHttpServic…ake sure they all have valid type or annotations.", stack: $
## _onError ##

这是众所周知的事情。您创建的套接字处于FIN_WAIT状态。要避免此问题，请在重新运行程序前等待2分钟，按照“graceful shutdown”协议或为套接字提供SO_REUSEADDR选项。

socket没有创建win32 c ++
