我创建简单的多线程服务器:
- 创建服务器
- 如果新连接创建新的 QThreadpool - QRunnable
- 在可运行向客户端发送消息并等待请求
- 如果客户端已断开连接,runnable 写入 qDebug 并 runnable 退出。
服务器.h
class Server : public QTcpServer
{
Q_OBJECT
public:
explicit Server(QObject *parent = 0);
void StartServer();
protected:
void incomingConnection(int handle);
private:
QThreadPool *pool;
};
服务器.cpp:
#include "server.h"
Server::Server(QObject *parent) :
QTcpServer(parent)
{
pool = new QThreadPool(this);
pool->setMaxThreadCount(10);
}
void Server::StartServer()
{
this->listen(QHostAddress(dts.ipAddress),80));
}
void Server::incomingConnection(int handle)
{
Runnable *task = new Runnable();
task->setAutoDelete(true);
task->SocketDescriptor = handle;
pool->start(task);
}
可运行的.h
class Runnable : public QRunnable
{
public:
Runnable();
int SocketDescriptor;
protected:
void run();
public slots:
void disconnectCln();
};
可运行的.cpp
#include "runnable.h"
Runnable::Runnable()
{
}
void Runnable::run()
{
if(!SocketDescriptor) return;
QTcpSocket *newSocketCon = new QTcpSocket();
newSocketCon->setSocketDescriptor(SocketDescriptor);
!!!怎么弄的???!!!QObgect::connect(newSocketCon, SIGNAL(disconnected()), this, SLOTS(disconnectCln()));
newSocketCon->write(mes.toUtf8().data());
newSocketCon->flush();
newSocketCon->waitForBytesWritten();
}
void Runnable::disconnectCln()
{
qDebug() << "Client was disconnect";
}
