您可以通过编写一些代码来实现您的目标。下面的代码是好的:

package userinfo;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class UserInfoServlet extends HttpServlet {

    private static final long serialVersionUID = 1L;

    public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
        doPost(request, response);
    }

    public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException {

        response.setContentType("text/html");
        PrintWriter out = response.getWriter();

        out.println("Headers<hr/>");

        Enumeration<String> headerNames = request.getHeaderNames();

        while (headerNames.hasMoreElements()) {
            String headerName = headerNames.nextElement();
            out.print("Header Name: <em>" + headerName);
            String headerValue = request.getHeader(headerName);
            out.print("</em>, Header Value: <em>" + headerValue);
            out.println("</em><br/>");
        }

    }
}
