I have a Flask Web Application that is periodically receiving JSON information from another application via HTTP POST.
My Flask Web Application is running on a CentOS 7 Server with Python 2.7.X.
I am able to parse the fields from this received JSON in the Flask Web Application and get some of the information that interests me. For example: I get some JSON input and extract an "ID":"7" field from it.
What I want to do now is run a perl script from within this Flask Web Application by using this "ID":"7".
Running 'perl my_perl_script.pl 7' manually on the command line works fine. What I want is for the Flask Web Application to perform this automatically whenever it receives an HTTP POST, by using the specific ID number found in this POST.
How can I do that in Flask? Is it a good idea to do it with a subprocess call or should I consider implementing queues with Celery/rq? Or maybe some other solution?
I think the perl script should be invoked as a separate Linux process, independent of the Flask Web Application.
Thank you in advance :)
