当PHP中的shell_exec()执行脚本时，Python open()函数不起作用
我的Python脚本中有一个open()命令，该命令在以w模式运行在Raspberry Pi上的Apache服务中打开文件data.json.该脚本又由PHP使用shell_exec命令运行.当脚本单独运行时，Python代码起作用. 但是，在由PHP运行时不起作用.有谁知道为什么会这样，还是需要更多信息?预先感谢您的帮助！
I have a open() command in my Python script which opens the file data.json in my Apache serve running on Raspberry Pi in w mode. This script in turn is run by PHP using the shell_exec command. When the script is run alone, the Python code works. However, it does not function when run by PHP. Does anyone have any idea why this is happening, or is more information needed? Thank you in advance for your help!

听起来像是特权问题，尽管我经验不足 从php调用Python以了解是否可能是一个问题 在这里.
Sounds like a privilege issue, although I am not experienced enough with calling Python from php to know whether that could be an issue here.
是的，这是一个特权问题！我通过在/var/www/html目录中执行sudo chmod 777 *命令来解决此问题.
and yes, it is a privilege issue! I fixed the problem by doing the sudo chmod 777 * command in the /var/www/html directory.
