我正在使用Qt使用QTcpServer创建TCP服务器.每次客户端连接到服务器时，我想知道远程主机的IP地址和端口号.我尝试搜索文档，但找不到有关此主题的任何信息.
I'm using Qt to create TCP server using QTcpServer. Every time a client connects to server, I would like to know the remote host's IP address and port number. I tried searching documentation but couldn't find any information on this topic.
我知道应该有办法，我只是无法弄清楚.请帮助.
I know there should be a way, I'm just not able to figure it out. Help please.
推荐答案
QTcpServer不会直接在传入连接上告诉您地址/端口，但是您可以通过从QTcpServer :: nextPendingConnection()获得连接的QTcpSocket来获得它.然后使用QTcpSocket的peerAddress()和peerPort()方法.
QTcpServer won't tell you the address/port directly on an incoming connection but you can get it by getting the connected QTcpSocket from QTcpServer::nextPendingConnection() and then using QTcpSocket's peerAddress() and peerPort() methods.
