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 " );
