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脚本将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。

有人可以帮助我找出我做错了什么吗？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;

  ?>

我的Python脚本

        else:
            print("not suceess")
else:
    print("end")

我没有收到任何错误，但是从PHP运行时文件没有下载

Answer 1

您可以检查您的下载URL写入权限吗？如果没有，请更改为755。

也可以尝试以下方法： $ command =“ python python_file.py -s $ store_id”; 做到：$ command =“ python python_file.py -s”。$ store_id;

使用Selenium无法在Python中下载文件|铬
