我写了一个RequestInfoServlet，可以显示HttpRequest的绝大部分有用信息，经过sso后，可以查看 HttpRequest里面还有什么东西。呵呵，我喜欢这样干。

代码

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;
import javax.servlet.ServletException;
import javax.servlet.http.Cookie;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
/**

*/
public class RequestInfoServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
//header
Enumeration headerNames = request.getHeaderNames();
out.println("*********[1].begin print headerNames************");
while (headerNames.hasMoreElements()) {
String name = (String) headerNames.nextElement();
String value = request.getHeader(name);
out.println(name + " = " + value + "");
}
out.println("*********[1].end print headerNames************");
//attributeNames
out.println("*********[2].begin print attributeNames************");
Enumeration attributeNames = request.getAttributeNames();
while (attributeNames.hasMoreElements()) {
String name = (String) attributeNames.nextElement();
String value = (String)request.getAttribute(name);
out.println(name + " = " + value + "");
}
out.println("*********[2].end print attributeNames************");
//parameterNames
out.println("*********[3].begin print parameterNames************");
Enumeration parameterNames = request.getParameterNames();
while (parameterNames.hasMoreElements()) {
String name = (String) parameterNames.nextElement();
String value = request.getParameter(name);
out.println(name + " = " + value + "");
}
out.println("*********[3].end print parameterNames************");
//session
out.println("*********[4].begin print session AttributeNames************");
HttpSession session = request.getSession();
Enumeration sAttributeNames = session.getAttributeNames();
while (sAttributeNames.hasMoreElements()) {
String name = (String) sAttributeNames.nextElement();
Object value = session.getAttribute(name);
out.println(name + " = " + value + "");
}
out.println("*********[4].end print session attributeNames************");
//cookie
out.println("*********[4].begin print Cookie************");
Cookie[] cookie = request.getCookies();
for(int i=0; i< cookie.length; i++) {
String name = cookie[i].getName();
String value = cookie[i].getValue();
out.println(name + " = " + value + "");
}
out.println("*********[4].end print Cookie************");
}
}
