🔒 Verifying image urls

[marsh cloud]

I'm trying to create a command that allows users to send an image url, but I would like to verify that the link actually leads to a valid image before having it stored in the database.

Also I'm using nextcord for this

hi

[marsh cloud]

greetings

[wheat leaf]

as a cogs data or in your main.py?

[marsh cloud]

in main.py

[wheat leaf]

ok

[cyan shell]

if os.path.exists(path)
and using if statement check the ending like .png or .jpg
but probably their is more easier way about what i don’t know

@marsh cloud

you can use a databank to save the images

a json file

[marsh cloud]

I'm pretty new at coding -- what exactly can a json file store?

[wheat leaf]

watch i created an example:

import discord
from discord.ext import commands
import requests
import json


# Loading data from JSON file
try:
    with open('allowed_images.json', 'r') as file:
        allowed_images = json.load(file)
except FileNotFoundError:
    allowed_images = []

# Function to save data to JSON file
def save_allowed_images():
    with open('allowed_images.json', 'w') as file:
        json.dump(allowed_images, file, indent=4)

@bot.command()
async def addimage(ctx, image_url: str):
    # List of allowed prefixes for the URL
    allowed_prefixes = ["https://", "http://"]

    # Checking if the link starts with an allowed prefix
    if not any(image_url.startswith(prefix) for prefix in allowed_prefixes):
        await ctx.send("The image URL must start with 'https://' or 'http://'.")
        return

    # Checking if the URL is already in the list
    if image_url in allowed_images:
        await ctx.send("The image URL is already allowed and was not saved again.")
    else:
        # The URL is valid, saving it to the database
        allowed_images.append(image_url)
        save_allowed_images()
        await ctx.send("The image URL has been successfully saved!")

i made notes above the codes #

please take this as an exercise and correct some information by yourself!
