How do I get the client name from a socket in Java?
提问by michael corrigan
Sorry, simple question...but I can't find the answer anywhere using google or in textbooks! I have a simple server, to which a user connects via a socket in java. I want to use this Java socket to retrieve the users client name, is this possible ?
对不起，简单的问题……但我无法在任何地方使用谷歌或教科书找到答案！我有一个简单的服务器，用户通过 java 中的套接字连接到该服务器。我想使用这个 Java 套接字来检索用户的客户端名称，这可能吗？
I know I can use the getInetAddress() method to returns the address to which the socket is connected, but that isn't really what I want. Is there any easy way of doing this ?
我知道我可以使用 getInetAddress() 方法返回套接字连接的地址，但这并不是我真正想要的。有没有简单的方法可以做到这一点？
Thank you.
谢谢你。

getInetAddress().getHostName()
EDIT: is your code structured like this?
编辑：您的代码结构是这样的吗？
import java.io.IOException;
import java.net.*;
public class Test {
public void foo() throws IOException{
ServerSocket server = null; //Initialize server socket here.
Socket client = server.accept();
String hostName = client.getInetAddress().getHostName();
}
}
