}使用方式
首先引入#include SocketManager.h
初始化
通过enum class Protocol { TCP, UDP };来选择TCP/UDP
通过第三个参数来决定如果是TCP的话是Service服务端还是Client客户端 socketManager new SocketManager(this);if (socketManager-initialize(SocketManager::Protocol::UDP, 127.0.0.1, 12345, false)) {qDebug() TCP Client initialized.;}else{qDebug() TCP Client fail.;}socketManager-setMessageCallback([](const QByteArray message) {qDebug() Received message: message;});
创建回调函数
收到消息通过回调函数的方式来接收数据
socketManager-setMessageCallback([](const QByteArray message) {qDebug() Received message: message;}); 最后我将项目放到GithubGitHub - xiugou798/QT6-Socket-Demo欢迎大家优化修改
