Help translating from python3 requests to urequests?.... "NotImplementedError: Redirects not yet supported"

[frazzmatazz]

I'm trying to move my python3 script to micropython on an ESP32 C3. It loads solar power and consumption data from my enphase envoy solar, to control hot water switching with a Shelly relay.

Unforunately I can't get a working urequests.get
something about: NotImplementedError: Redirects not yet supported

This works in python3:
But generates warning about a self signed certificate. The data isn't important.

#!/usr/bin/python3
import requests
from requests.structures import CaseInsensitiveDict
import json

#urllib3.disable_warnings() # avoid InsecureRequestWarning
headers = CaseInsensitiveDict()
headers["Accept"] = "application/json"
headers["Authorization"] = "Bearer eyJraWQiOiI3ZDEwMDA1ZC03ODk5LTRkMGQtYmNiNC0yNDRmOThlZTE1NmIiLCJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJhdWQiOiIxMjIxMzQwNjM2MjMiLCJpc3MiOiJFb-LONGJAZZHERE"

url = 'http://192.168.1.101/production.json'

response = requests.get(url, headers=headers, verify=False) # self-signed certificate
print(response)

json_data = json.loads(response.text)
solar_production = json_data['production'][1]['wNow']
power_consumption = json_data['consumption'][0]['wNow']
print("{:.1f}".format(solar_production), "W production,", "{:.1f}".format(power_consumption), "W consumption,")

/usr/lib/python3/dist-packages/urllib3/connectionpool.py:1048: InsecureRequestWarning: Unverified HTTPS request is being made to host '192.168.1.101'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/1.26.x/advanced-usage.html#ssl-warnings
warnings.warn(
<Response [200]>
482.9 W production, 216.4 W consumption,

In micropython so far I have this:
(Slightly rejigged header layout.)

import urequests
import time

url = 'http://192.168.1.101/production.json'

headers = { 
    "Accept": "application/json",
    "Authorization": "Bearer eyJraWQiOiI3ZDEwMDA1ZC03ODk5LTRkMGQtYmNiNC0yNDRmOThlZTE1NmIiLCJ0eXAiOiJKV1QiLCJhbGciOiJFUzI1NiJ9.eyJhdWQiOiIxMjIxMzQwNjM2MjMiLCJpc3MiOiJFbnRyZXoiLCJlbnBoYXNlVXNlciI6Im93bmVyIiwiZXhwIjoxNzI5ODkxODQ5LCJpYX-LONGJAZZHERE",
    }

#print(headers)

response = urequests.get(url, headers=headers) # self-signed certificate
print(response.text)

Traceback (most recent call last):
File "", line 15, in
File "/lib/urequests.py", line 112, in get
File "/lib/urequests.py", line 97, in request
NotImplementedError: Redirects not yet supported

Thanks!

I've found this snippet to work out what redirection is happening:

if response.history:
    print("Request was redirected")
    for resp in response.history:
        print(resp.status_code, resp.url)
    print("Final destination:")
    print(response.status_code, response.url)
else:
    print("Request was not redirected")

And the output was:

Request was redirected
301 http://192.168.1.101/production.json
Final destination:
200 https://192.168.1.101/production.json

So I fixed my script to point to https!
