如题，代码如下，菜鸟来学习，没找到答案：

function get_config(id){
var option= {
            url:'http://XXXXXXXX',
            headers:{
                "Content-Type":"application/xml",
                "Accept":"application/xml",
               }
        };
    request.get(
       option,
        function(error, response, body){
            if(response.statusCode ==200){
                console.log(body);                //配置文件在body中,能在这里直接对body进行修改吗？修改完后又怎么把body post?
				....
                request.post(				
				option,
				 function(error, response, body){
				 ...
				 } )
                }
            else{
                console.log(response.statusCode);
            }

        }

    )
}

谢谢…
