import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
public class ClientAddressServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//获取客户的IP地址
String clientIP = request.getRemoteAddr();
//获取客户的主机名
String clintHost = request.getRemoteHost();
response.setContentType("text/plain");
PrintWriter out = response.getWriter();
out.println("IP : " + clientIP);
out.println("Host: " + clintHost);
