客户端代码：

let PORT: number = 8080;
    let IP: string = "127.0.0.1";
export class NetSocket extends Laya.Socket{

        }

        public conectToServer(): void { //“连接”按钮的回调
            if (this.connected) return;

        }

    }

服务器代码：（c语言）

int main(int argc, char* argv[])
{
    //初始化WSA  
    WORD sockVersion = MAKEWORD(2, 2);
    WSADATA wsaData;
    if (WSAStartup(sockVersion, &wsaData) != 0)
    {
        return 0;
    }

    //创建套接字  
    SOCKET slisten = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (slisten == INVALID_SOCKET)
    {
        printf("socket error !");
        return 0;
    }

    //绑定IP和端口  
    sockaddr_in sin;
    sin.sin_family = AF_INET;
    sin.sin_port = htons(8080);
    sin.sin_addr.S_un.S_addr = INADDR_ANY;
    if (bind(slisten, (LPSOCKADDR)&sin, sizeof(sin)) == SOCKET_ERROR)
    {
        printf("bind error !");
    }

    //开始监听  
    if (listen(slisten, 5) == SOCKET_ERROR)
    {
        printf("listen error !");
        return 0;
    }

    //循环接收数据  
    SOCKET sClient;
    sockaddr_in remoteAddr;
    int nAddrlen = sizeof(remoteAddr);
    char buffData[1000] = {0};
    int buffLen = sizeof(buffData);
    char *finalStr = "";

    printf("等待连接...\n");
    sClient = accept(slisten, (SOCKADDR *)&remoteAddr, &nAddrlen);
    if (sClient == INVALID_SOCKET)
    {
        printf("accept error !");
        return 0;
    }
    printf("接收到一个连接：%s \r\n", inet_ntoa(remoteAddr.sin_addr));
    
    recv(sClient, buffData, buffLen, 0);
    printf("收到的字符串是：%s\n", buffData);

    while (true)
    {
        memset(buffData, '\0', sizeof(buffData));
        recv(sClient, buffData, buffLen, 0);
        printf("收到的字符串是：%s\n", finalStr);
 
         char * sendData = "hello client.";
         send(sClient, sendData, strlen(sendData), 0);
    }

    closesocket(slisten);
    WSACleanup();
    return 0;
}

服务器打印出一串文本后就没反应了，客户端也没有触发onConected或者_onOpen函数，下面是服务器打印的文本

等待连接...
