JSP中request.getParameterNames和getParameterValues应用

try{


String name;


Enumeration pNames=request.getParameterNames();


while(pNames.hasMoreElements()){


name=(String)pNames.nextElement();


out.print(name+"="+request.getParameter(name));


}


}catch(Exception e){


out.print(e.toString());


}




for (Enumeration iter = request.getParameterNames(); iter.hasMoreElements();) {


String element = (String) iter.nextElement();


logger.debug("parameter:"+element);


logger.debug("value:"+request.getParameter(element));


}

String[] userId = request.getParameterValues("userId");
