从Django项目中调用PHP脚本：无法打开输入文件

Question

I wrote a PHP script that processes some task for me (specifically, encoding videos on a media server). I tested calling this script via python like so:

proc = subprocess.Popen("php vodworkflow_drm_playready_widevine.php videos " +str(video), shell=True, stdout=subprocess.PIPE)

This worked correctly (i.e. the video name passed to the script got correctly encoded and such). However, when I call Popen from inside my Django project, I instead get the output: Could not open input file: my_script.php.

I'm stumped! Can anyone help with what could be going on, and what I can do to rectify this? Thanks, I've been stuck since a while now. Do let me know if you need to see the PHP script and more detailed code.

Answer 1

Point the php file to php binary by its full path.

proc = subprocess.Popen("php /root/www/bla_bla/vodworkflow_drm_playready_widevine.php videos " +str(video), shell=True, stdout=subprocess.PIPE)

Alternatively, Popen takes an cwd argument. Specify the path to it.
