使用 Selenium 在 Python 中未下载文件 |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，脚本会运行但不会下载文件。

我在无头模式下使用 Selenium 和 Chrome-webdriver。

谁能帮我找出我做错了什么？我在 Ubuntu Linux OS 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，但从 PHP 运行时没有下载文件

您可以检查您的下载 URL 写入权限吗？如果没有，则将其更改为 755。

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