文件未使用 Selenium 在 Python 中下载 |铬

Question

我有从网站下载文件的python脚本。当我从终端传递参数时，Python 脚本在后台运行并成功下载文件。但是当我从 PHP 文件传递参数时，脚本运行但不下载文件。

我正在无头模式下使用Selenium和Chrome网络驱动程序。

谁能帮我找出我做错的地方？我正在 Ubuntu Linux 操作系统上运行脚本。

我的 PHP 脚本

 <form method="post" action="CsvDownload.php" >
        <label>Store Id</label>
        <input type="text" class="form-control" name="storeId" id="store_id">
    <button type="submit" class="btn btn-success"> Submit</button>
 </form>
<?php
    ini_set('max_execution_time', 300);
    $store_id = false;
    if(isset($_POST['storeId'])){
        $store_id = $_POST['storeId'];
     } 
    $command = "python python_file.py -s $store_id";
    $output = exec($command);
    echo $output;
  ?>

我没有收到任何错误，但是从PHP运行时文件无法下载

你能检查你的下载URL写入权限吗？如果没有，请将其更改为 755。

也尝试这样做，而不是：$command = "python python_file.py -s $store_id";制作它： $command = "python python_file.py -s ".$store_id;
