【问题描述】：

我已经搜索并阅读了其他有类似问题的帖子。我修复了 .py 文件中的 shebang 行，并确保 httpd.conf 具有正确的配置。不幸的是，没有什么能解决我的问题，我仍然遇到可怕的错误 -

[Mon Jun 01 10:37:02.994516 2020] [cgi:error] [pid 19596:tid 1196] (OS 1920)The file cannot be accessed by the system.  : [client ::1:50159] couldn't create child process: 721920: upload_file.py
[Mon Jun 01 10:37:02.994516 2020] [cgi:error] [pid 19596:tid 1196] (OS 1920)The file cannot be accessed by the system.  : [client ::1:50159] AH01223: couldn't spawn child process: C:/Users/raj_d/webroot/tsp_quick/cgi-bin/upload_file.py

Python 脚本 -

#!"C:\Users\raj_d\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\python.exe"
import cgi, os
import cgitb

cgitb.enable()
form = cgi.FieldStorage()
# Get filename here.
fileitem = form['filename']
# Test if the file was uploaded
if fileitem.filename:
   # strip leading path from file name to avoid
   # directory traversal attacks
   fn = os.path.basename(fileitem.filename)
   open('/tmp/' + fn, 'wb').write(fileitem.file.read())
   message = 'The file "' + fn + '" was uploaded successfully'
else:
   message = 'No file was uploaded'
print """\
Content-Type: text/html\n
<html>
<body>
   <p>%s</p>
</body>
</html>
""" % (message,)

我玩过在 shebang 的完整路径上添加和删除引号，但没有帮助。

我在 httpd.conf 中有这些 -

LoadModule cgi_module modules/mod_cgi.so

<Directory "C:\Users\raj_d\webroot\tsp_quick\cgi-bin">
    AllowOverride None
    # Options None
    Options +ExecCGI
    AddHandler cgi-script .py
    Require all granted
</Directory>

我确保 python 可以从 shebang 路径执行 -

C:\>C:\Users\raj_d\AppData\Local\Microsoft\WindowsApps\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\python.exe
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1924 64 bit (AMD64)] on win32

任何帮助将不胜感激。

提前致谢。

【解决方案1】：

好吧，我想通了。

首先，一个人应该始终遵循准则:)

就我而言，我放弃了从命令行运行脚本的速度太快了。我从 Microsoft 商店安装了 Python 3.8.3，出于某种原因，每次我从命令行运行脚本时，都会弹出一个新的 cmd 窗口并很快关闭。我无法改变这种行为，也看不出出了什么问题。

所以我卸载了 python，从 python 的站点下载了新的安装程序，并安装在我的开发工具安装的公共位置。现在，我可以从命令行运行我的脚本，并且能够看到实际的问题是什么。

原来是打印！这是修改后的代码，效果很好，shebang也变得更简单了。

#!C:\tools\python\\python.exe
import cgi, os
import cgitb
import time

cgitb.enable()
form = cgi.FieldStorage()
# Get filename here.
fileitem = form['filename']
# Test if the file was uploaded
if fileitem.filename:
   # strip leading path from file name to avoid
   # directory traversal attacks
   fn = os.path.basename(fileitem.filename)
   # open('/tmp/' + fn, 'wb').write(fileitem.file.read())
   message = 'The file "' + fn + '" was uploaded successfully'
else:
   message = 'No file was uploaded'
a = """Content-Type: text/html\n
<html>
<body>
<p>{}</p>
</body>
</html>
"""
print (a.format(message))
