无法使用 XAMPP 从 Python cgi 脚本写入 PYTHON_EGG_CACHE

Question

我有这个简单的脚本可以通过 ssh 连接到服务器，如果我运行来自 shell 的脚本，它就可以工作，但是当我从 cgi-bin 调用脚本时它不会(http://localhost/cgi-bin/test.py)

#!C:\Python27\python

print "Content-type: text/html\n\n"

import spur
shell = spur.SshShell(hostname="192.168.1.5", username="user", password="pass", missing_host_key=spur.ssh.MissingHostKey.accept)
result = shell.run(["pwd"])
print result.output

我在 Windows 上使用 XAMPP 并且我编辑了 httpd.conf 以接受来自 cgi-bin 的 .py 文件，实际上是一个简单的

#!C:\Python27\python

print "Content-type: text/html\n\n"
print "Test"

在浏览器中工作。

在我的Apache日志中发现错误如下：

pkg_resources.ExtractionError: Can't extract file(s) to egg cache

The following error occurred while trying to extract file(s) to the Python egg
cache:

  [Error 5] Accesso negato: 'C:\\Windows\\Application Data'

The Python egg cache directory is currently set to:

  C:\Windows\Application Data\Python-Eggs

Perhaps your account does not have write access to this directory?  You can
change the cache directory by setting the PYTHON_EGG_CACHE environment
variable to point to an accessible directory.

提前致谢

一个开始的地方是将 paramiko（以及其他依赖项，如果此错误再次出现）直接安装到您现有的 Python 安装中，这样就不需要将其下载并提取为 egg (因此不需要适合该任务的文件权限）。例如：

c:\Python\Scripts\easy_install.exe --always-unzip paramiko

允许您的 Web 服务器写入存储代码的位置（Python eggs 是代码！）是非常糟糕的安全做法（妥协后，攻击者可以将自己的内容放在那里，并它总是运行当加载 paramiko 或其他库时。
