1、TCP Client🔗 使用QTcpSocket实现TCP Client,十分详细的入门Demo 支持打开多个TCP Client窗口;👍 可选择是否以16进制字符串形式显示发送、接收的数据;👍 自动统计发送数据的总字节大小、接收数据的总字节大小;👌 判断TCP Socket状态变化;✌️

1.QT中实现TCP通信主要用到了以下类:QTcpServer、QTcpSocket、QHostAddress 2.基本流程: 使用QTcpServer来创建一个TCP服务器,在新的连接建立时,将新建立连接的socket添加到列表中,以便发送数据,同时监听在指定的IP地址和端口上,并在有新的客户端连接上来时进行处理; 使用QTcpSocket来创建一个TCP客户端,连接到服...
connect(mSocket,SIGNAL(readyRead()),this,SLOT(read_client_data())); //检测掉线信号 connect(mSocket,SIGNAL(disconnected()),this,SLOT(client_dis())); } void TcpServer::read_client_data() { //可以实现同时读取多个客户端发送过来的消息 QTcpSocket *obj = (QTcpSocket*)sender(); QString msg...

这里比较有意思的是,客户端连接到服务器->客户端(tcpClient)触发startTransfer槽函数->调用tcpClient.write->触发QIODevice::bytesWritten信号->触发updateClientProgress槽函数调用->就一直tcpClient.write,直到if条件不成立后后停止发送。 voidDialog::startTransfer(){// called when the TCP client connected to...

tcpClient.connectToHost(QHostAddress::LocalHost,tcpServer.serverPort()); 这里比较有意思的是,客户端连接到服务器->客户端(tcpClient)触发startTransfer槽函数->调用tcpClient.write->触发QIODevice::bytesWritten信号->触发updateClientProgress槽函数调用->就一直tcpClient.write,直到if条件不成立后后停止发送。
