以下tests.py工作正常，并通过subprocess.call执行powershell脚本：

import subprocess

subprocess.call(["C:\\WINDOWS\\system32\\WindowsPowerShell\\v1.0\\powershell.exe", ". \"./testers.ps1\";", "&Foo(10)"])

尝试从django/rest视图中执行相同的调用失败：

import subprocess

from rest_framework.response import Response
from rest_framework import status
from rest_framework.decorators import api_view

@api_view(['POST'])
def bar(request):
    if request.method == 'POST':
        subprocess.call([f"C:\\WINDOWS\\system32\\WindowsPowerShell\\v1.0\\powershell.exe", ". \"./testers.ps1\";", "&Foo({request.data})"])

        return Response(request.data, status=status.HTTP_201_CREATED)
    else:
        return Response(request.errors, status=status.HTTP_400_BAD_REQUEST)

错误：

ps脚本：

Function Foo($intIN)
{
    Write-Host ($intIN + 1)
}

Write-Host "PowerShell sample says hello."

为什么我可以从tests.py运行它，但不能从django视图中运行它？对我来说，执行此操作的最佳方式是什么？
