从PHP控制器调用带有request.post（）的python脚本永远不会返回。为什么？

我正在尝试从Laravel8应用程序执行python脚本。python脚本使用Laravel应用程序的RESTAPI，因此它必须进行身份验证

如果python脚本在命令行（开发平台是Windows 10）上运行，它本身运行得很好，但是如果通过shell_exec（）或exec（）或symfony/process（）运行，它会关闭Laravel应用程序，直到我需要在另一个端口上重新启动应用程序，或者在控制台、Laravel日志中没有错误地重新启动

如果我从python脚本中取出'requests.post（）'并将其替换为print（“helloworld”），那么shell_exec（）就可以正常工作

问题：有人看到可能发生的事情吗？这似乎是权限问题，但我不确定

脚注：我尝试了Symfony，但得到了一个错误，许多其他人报告说“无法获取随机数来初始化Python运行时”。这似乎是windows开发环境中的常见问题。解决了这个问题，但结果是一样的。对于将来看到此python初始化错误的任何人：在windows构建环境中，需要按如下方式添加环境变量SystemRoot:

$process=new process（[$python，$process\u path，$argument1，$argument2]，null，['SystemRoot'=>'C:\windows']）

控制器

    public function startprocess(Request $request)
    {

        $python = "C:/Users/dev/AppData/Local/Programs/Python/Python38/python.exe";
        $process_path = "C:/Apache24/htdocs/project/resources/python/lambda/test.py";
        $complete_path = $python." ".$process_path;
        $output = [];
        $return_var = "";

//        exec($complete_path, $output, $return_var);
        $process = new Process([$python, $process_path], null, ['SystemRoot' => 'C:\WINDOWS']);
        $process->run();

        return view('admin.scheduledtasks_data', compact('output', 'return_var', 'complete_path'))->render();
    }

Python代码

import sys
import requests
from requests.exceptions import HTTPError
import re

url_login = 'http://127.0.0.1:8089/api/apilogin'

data = {
    'email': 'myemail@email.com',
    'password': 'password'}

returned_data = requests.post(url_login, data=data)  #<<THIS TAKES DOWN THE SERVER

下面是从命令行发出的好请求

import sys
import requests
from requests.exceptions import HTTPError
import re

url_login = 'http://127.0.0.1:8089/api/apilogin'

data = {
    'email': 'myemail@email.com',
    'password': 'password'}

returned_data = requests.post(url_login, data=data)  #<<THIS TAKES DOWN THE SERVER

下面是我使用requests.post（url\u login，data=data，timeout=3）从laravel应用程序调用它时的响应，添加了“timeout”，但从未发生登录。如果没有超时，请求将永远不会返回，服务器将停机

去掉Symfony process（）并改为此。发生的情况是laravel应用程序阻止了request.post的完成，因此服务器被锁定

function execInBackground($cmd) {
    if (substr(php_uname(), 0, 7) == "Windows"){
        pclose(popen("start /B ". $cmd, "r")); 
    }
    else {
        exec($cmd . " > /dev/null &");
