我创建了这个服务器类，它在新连接进入时启动一个线程。在某些情况下它可以正常工作，但它不是很稳定。我正在尝试解决它在哪里中断。我的调试器告诉我一些关于 qmutex 的信息。如果有人能发现问题。泰
它通过信号和插槽与父级连接并获取数据。
这是标题：

这是来自父母：
//server start

adr.setAddress( QString("127.0.0.1") );
adr.toIPv4Address();
quint16 port = 1101;
if (!server.listen( adr, port)) {

tr("Unable to start the server: %1.")
.arg(server.errorString()));
close();
return;
}
QString ipAddress;
ipAddress = server.serverAddress().toString();
statusLabel->setText(tr("The server is running on\n\nIP: %1\nport: %2\n\n"
"Run the Fortune Client example now.")
.arg(ipAddress).arg(server.serverPort()));
connect (&server, SIGNAL(procesServerStringToParent(string)), this, SLOT(procesServerString(string)));
connect (this, SIGNAL(StringToServer(string)), &server, SLOT(getStringToThread(string)));
编辑：我正在尝试做的事情：
我有一个客户端（游戏引擎（Cryengine）的一部分），我用它发送了一串游戏坐标和其他一些东西，就像它在我之前给出的链接中所做的那样。这工作正常。我在“127.0.0.1”端口 1101 上获取数据。现在我只需要在我自己的程序中评估这些数据，该程序有这个 TableView 类，我可以在其中收集从字符串中获取的坐标，从坐标中调用一些数据和然后通过服务器将这个新字符串返回给游戏引擎。在游戏中，我将单击对象获取它们的坐标，从中创建一个字符串（包含坐标、实体 ID 等），将此字符串发送到服务器，从 TableView 返回调用信息。我只需要这种单向流只有一个正在发送字符串的客户端。我不确定 recv(hsock, buffer, buffer_len, 0), 我猜在游戏中负责发送字符串的节点会等待返回字符串？这是我的第一个程序之一，我真的很困惑......
