def main(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:

Run it f5, view terminal

Functions:

        coinfunction01: [GET,POST] http://localhost:7071/api/coinfunction01

Stop shift + f5 stop if shift + 5, and press any key in terminal

Folder structure, we added coinworker.py and urls_firi.py

New init code

import logging
import coinworker as cw

import azure.functions as func


def main(req: func.HttpRequest) -> func.HttpResponse:
    worker = cw.CoinWorker()
    logging.info('Python HTTP trigger function processed a request.' + str(worker))

    return func.HttpResponse(str(worker.get_solnok()), mimetype="text/json")

Run it f5, stop if shift + 5, and press any key in terminal

Ok, we are happy.

Deploy Azure

Select subscription Choose the subscription to use.

You won’t see this prompt when you have only one subscription visible under Resources.

Enter a globally unique name for the function app Type a name that is valid in a URL path. The name you type is validated to make sure that it’s unique in Azure Functions.

Select a runtime stack Choose the language version on which you’ve been running locally.

Select a location for new resources Choose a region for your function app.

Hm, just blank page

Edit init to

import logging
# import coinworker as cw
import random

import azure.functions as func


def main(req: func.HttpRequest) -> func.HttpResponse:
    # worker = cw.CoinWorker()
    logging.info('Python HTTP trigger function processed a request.')
    # comment
    # Test change on GET
    ran  = random.randint(0,89)
    return func.HttpResponse(str(ran), mimetype="text/json")
    # return func.HttpResponse(str(worker.get_solnok()), mimetype="text/json")

That works, something wrong from local to Azure, hm.

python requests – Calling a REST API using Azure function App and store data in Azure container – Stack Overflow

sucks, only show a var, hm….

Must update requirements, args since import requests. API should work, perfect.

Now it works

All the code is now in init, can move this to different modules now, the import was the issue
