如何获取所有的参数名和参数值？用request.getParameterNames(); Enumeration enu=request.getParameterNames(); while(enu.hasMoreElements()){ String paraName=(String)enu.nextElement(); System.out.println(paraName+"

用request.getParameterNames();  
Enumeration enu=request.getParameterNames();  
while(enu.hasMoreElements()){  
String paraName=(String)enu.nextElement();  
System.out.println(paraName+": "+request.getParameter(paraName));  
}
