php - 从php错误执行python文件

Question

我有一些问题。

这个 php (uploads.php) 脚本执行 gif.py python 文件。

<?php


    $file_path = "uploads/";
    $auth_token = $_POST['auth_token'];
    mysql_connect('localhost',"login",'pass');
    mysql_set_charset("UTF-8");
    mysql_select_db("DB_name");

    $sql = "SELECT user_id FROM users WHERE auth_token='$auth_token'";
    $result = mysql_query($sql);

    if(mysql_fetch_array($result)['user_id']==0)
    {
        echo "fail auth_token ".$auth_token;
        exit;
    }

    $file_md5 = md5(time()+$auth_token+rand(0,1000));

    $file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], "uploads/".$file_md5.".mp4")) {
        $aaa = exec("/usr/bin/python gif.py b9022c5c317cf2317ad3f537dcc1cfbe");
        echo $file_md5."   ".$aaa;
    } else{
        echo "fail ".$_FILES['uploaded_file']['size']." ".$_FILES['uploaded_file']['tmp_name']." ".$file_path ;
    }
 ?>

gif.py 文件

#!/usr/bin/env python
from moviepy.editor import *
import sys

file_md5 = sys.argv[1]

anna_olaf = (VideoFileClip("uploads/" + file_md5+".mp4")
     .subclip(0,1)
         .resize(1))  

anna_olaf.write_gif('gifs/test.gif', fps=15)

我在上传文件夹中有 b9022c5c317cf2317ad3f537dcc1cfbe.mp4 文件。我从 Linux 控制台调用 gif.py 或 uploads.php 文件的地方一切正常(php uploads.php 或 pyhon gif.py)，但是我从浏览器 python 文件调用 uploads.php 的地方不起作用，在 apache 日志中我发现

/usr/lib/python2.7/dist-packages/IPython/utils/path.py:296: UserWarning: IPython parent '/var/www' is not a writable location, using a temp directory.

    raise RuntimeError("Failed to create %s/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data"%h)
RuntimeError: Failed to create /var/www/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data

请帮忙，在日志中的第2行写入错误(from moviepy.editor import *)但为什么我在调用(python gif.py)时没有错误？

正如评论中所讨论的，问题显示在错误报告的最后一行，请参阅:

RuntimeError: Failed to create /var/www/.matplotlib; consider setting MPLCONFIGDIR to a writable directory for matplotlib configuration data 

我想说这可能是 /var/www/ 文件夹的权限问题，不允许脚本根据需要创建文件。

要解决此问题，您应该更改文件夹的权限以使其可写，或指定脚本应在其中创建所需文件的不同目录。
