cowin-vaccine-notifier's Issues

Hardcoded paramaters in the script

CoWin-Vaccine-Notifier/script.py

Line 13 in db2bfc1

age = 52

Instead of hardcoding parameters, the script should take parameters on command line. User may not want to edit code Everytime for changing parameters according to them.

pygame.error: Couldn't open 'sound/dingdong.wav'

Getting error pygame.error: Couldn't open 'sound/dingdong.wav'

Mismatch of results

My code is running fine but printing two different results for the same center

The Program is static. It's not taking any input form user

It's not taking any input form user

Counter says no vaccination available even if the availability is there

Cowin API is not Realtime!

Hello. I had tried to make a similar Vaccine Notifier using the COWIN's public API. However, the API is not realtime anymore. According to the official website, they cache the data for 30 minutes. However, according to my experience and my testing, the data is being cached for more than 30 mins (often for more than 5-6 hours).

requested URL not working

getting 'InsecureRequestWarning: Unverified HTTPS request is being made to host' exception while requesting below URL

URL = "https://cdn-api.co-vin.in/api/v2/appointment/sessions/public/calendarByPin?pincode={}&date={}".format(pincode, given_date)
header = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.76 Safari/537.36'}

Changed and optimized sleep code.

Please have a look at : https://github.com/sktg84/CoWin-Vaccine-Notifier

Optimized the sleep as it hogs CPU by checking every second , added district and state based check

Unstructured format of the script

CoWin-Vaccine-Notifier/script.py

Line 19 in db2bfc1

print("Starting search for Covid vaccine slots!")

The script does it's job but code is not maintainable. The script could be refactored to follow an OOP approach and could be written as a Class.

Benefits of structuring the script as a Class :

1. Easier to write specs (unit test cases).
2. Easier to publish the Class file as a library that could be directly imported into other projects.

ModuleNotFoundError

pygame and requests module needed to intstall manually.

Can be modified with OOP approach and converted to CLI

The script is working fine, however, it's not maintainable if code goes on steroids

Suggestions

• OOP approach can be followed and there can be different functions for each task
• Can be converted into a CLI tool
• Hardcoded values can be changed to user inputs

Benefits

• Maintainable code
• If code goes on steroids, there won't be an issue as each task has separate funcs
• No need to run via vs code
