获取HttpServletRequest中的所有参数

参考:https://sjeveryday.iteye.com/blog/1630596

一丶获取请求中的参数
request里有两个方法
request.getParameterMap();
request.getParameterNames();

1.用request.getParameterNames();

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

2.request.getParameterMap();

Map map=request.getParameterMap();  
    Set keSet=map.entrySet();  
    for(Iterator itr=keSet.iterator();itr.hasNext();){  
        Map.Entry me=(Map.Entry)itr.next();  
        Object ok=me.getKey();  
        Object ov=me.getValue();  
        String[] value=new String[1];  
        if(ov instanceof String[]){  
            value=(String[])ov;  
        }else{  
            value[0]=ov.toString();  
        }  
  
        for(int k=0;k
