TcpServer 类 vSetDriver 和 vSetListener 方法用于设置驱动和监听对象。vTcpServerStart 方法用于启动服务器。incomingConnection 方法处理新的连接。onReadyRead 和 onDisconnected 方法分别处理数据接收和连接断开事件。 TcpClient 类 connectToServer 方法连接到服务器。sendData 方法发送数据。onReadyRead、onConnected 和 onDisconnected 方法分别处理数据接收、连接和断开事件。 主程序 创建并配置服务器和客户端对象。客户端连接到服务器并发送数据。
这个示例演示了如何使用 Qt 的网络模块创建一个简单的 TCP 服务器和客户端并展示了如何通过自定义的 vSetDriver、vSetListener 和 vTcpServerStart 方法进行初始化和管理。 如何测试 1. 准备项目结构
确保项目文件结构正确并包含以下文件
tcpserver.htcpserver.cpptcpclient.htcpclient.cppmain.cppmyproject.pro 2. 项目配置文件 (myproject.pro)
确保你的项目配置文件 (myproject.pro) 正确配置
QT core network
CONFIG console
CONFIG - app_bundleTEMPLATE app
SOURCES main.cpp \tcpserver.cpp \tcpclient.cppHEADERS tcpserver.h \tcpclient.h3. 编译项目
使用 qmake 和 make 编译项目。在终端中执行以下命令
qmake myproject.pro
make4. 运行测试
在编译成功后运行生成的可执行文件。以下是测试步骤
4.1 启动服务器
在一个终端中运行服务器部分
./myproject此时服务器应该启动并监听端口 12345等待客户端连接。
4.2 启动客户端
在另一个终端中运行客户端部分
./myproject此时客户端应该连接到服务器并发送 “Hello, Server!” 消息。
5. 验证测试结果 检查服务器输出
服务器应该输出类似以下的日志信息
Server started!
connect : 127.0.0.1(12345)
recv : 127.0.0.1(12345)检查客户端输出
客户端应该输出类似以下的日志信息
Connected to server6. 修改和扩展
根据需要修改和扩展你的代码。例如你可以在 recvData 信号处理函数中添加更多的处理逻辑或者在客户端中添加接收服务器响应的功能。
