Question

所以我正在实现一个包含不同 HTML 按钮的 Django 网页，每个 HTML 按钮执行不同的 Python 脚本。执行外部脚本的按钮会显示错误。这是 HTML 代码

<form action="/external/" method="POST">
{% csrf_token %}

{{data_external}}<br><br>
{{data1}}
<br><br>
<input type="submit" value="Execute External Python Script">

</form>

这里是 views.py :


def external(request):
    inp= request.POST.get('param')
    out= run([sys.executable,'/scripts/test.py',inp],shell=False,stdout=PIPE)
    print(out)
    return render(request,'web_app/home.html',{'data1':out.stdout})

错误如下：

     Internal Server Error: /external/
Traceback (most recent call last):
  File "C:\Users\User\AppData\Local\Programs\Python\Python39\lib\site-packages\django\core\handlers\exception.py", line 47, in inner

    for arg in map(os.fsdecode, seq):

    filename = fspath(filename)  # Does type-checking of `filename`.
TypeError: expected str, bytes or os.PathLike object, not NoneType

我应该如何解决这个问题？
