App for API Endpoint only in Python3

anjanesh

I want to create an app that just serves endpoints for an API in Python3.

So what app do I create in order to execute the following at api.mydomain.com/getSomething.py?arg1=xx1&arg2=xx2 ?

#!/usr/bin/env python3
# chmod 755 getSomething.py

import os, sys, time, cgi, cgitb, re
import json, hashlib, gzip, urllib, urllib2
cgitb.enable()
...

PHP-CGI with Apache ?

Or is there a better way to handle this not using CGI ?

anjanesh I recommend a Python/uWSGI app instead of CGI. The wsgi.py included with the installer is a basic starting point.

If you want to use CGI anyway then use an Apache/CGI app. An example is here: HOWTO run CGI scripts on Opalstack

What's the advantage of using uWSGI over CGI ?

My current site is on PHP-Apache with the API as python 2 scripts that I wrote long back when I was at Webfaction 10 years ago. I didn't update as it's working as-is on OpalStack too. Now I am thinking of having the API for end-users as a service, is possible. So need to think about thousands of requests (per time) if / when the need arises.

anjanesh if you're looking at 1000s of requests then you do not want CGI, my advice is that you re-deploy your app as uWSGI.

Is there some tutorial on how to create uWSGI apps ? I just want to throw a bunch of JSON via Python3.

anjanesh "uWSGI" is a server like Apache, so there isn't really a concept of a "uWSGI" application.

If you want to try a Python WSGI app similar to a basic CGI script but served by uWSGI, then here's a basic "hello world' example:

from cgi import parse_qs, escape

def application(env, start_response):
    # get the query string
    qs = parse_qs(env.get('QUERY_STRING', ''))

    # get name from the query string
    name=''
    if 'name' in qs:
        name = escape(qs['name'][0])

    # return the response
    resp = bytes(f'hello {name}', 'utf-8')
    start_response('200 OK', [('Content-Type','text/html')])
    return [resp]

If you create a uwsgi app via our dashboard and replace the included myapp/wsgi.py with the above example then you'll be able to test it and modify it from there.
