对get和post请求的编码

if("GET".equals(method)){   
			try {
				value = request.getParameter(name);//乱码
				byte[] buf = value.getBytes("ISO8859-1");
				value = new String(buf,"UTF-8");//正码
			} catch (Exception e) {
				e.printStackTrace();
			}
		}else if("POST".equals(method)){
			try {
				request.setCharacterEncoding("UTF-8");
				value = request.getParameter(name);//正码
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
