User: aiogram 3 how to all get messages in channel?
Assistant: To get all messages from a channel using Aiogram 3, you'll typically need to interact with the Telegram Bot API and handle messages within the context of updates. However, note that bots cannot read all messages in any channel; they can only access messages that mention the bot or are in channels where the bot has admin privileges. Here's a step-by-step pseudocode outline and example code to get started:

**Pseudocode:**

1. Set up your Aiogram bot with API token.
2. Define dispatcher to handle updates.
3. Create a handler function to process incoming messages.
4. Configure the bot to listen for new messages.
5. Implement logic within the handler to process and store messages.

**Code Example:**

```python
# aiogram3_example.py
from aiogram import Bot, Dispatcher, types
from aiogram.contrib.middlewares.logging import LoggingMiddleware
from aiogram.types import Message
from aiogram.utils import executor

API_TOKEN = 'YOUR_BOT_API_TOKEN'

# Initialize bot and dispatcher
bot = Bot(token=API_TOKEN)
dp = Dispatcher(bot)
dp.middleware.setup(LoggingMiddleware())

@dp.message_handler(content_types=types.ContentType.ANY)
async def handle_message(message: Message):
    # Process the incoming message
    channel_id = message.chat.id
    message_id = message.message_id
    text = message.text
    print(f"Received message from channel {channel_id}: {text} - ID: {message_id}")

if __name__ == '__main__':
    # Start polling for updates
    executor.start_polling(dp, skip_updates=True)
```

Ensure you replace `'YOUR_BOT_API_TOKEN'` with your actual Telegram bot API token. This script sets up a basic Aiogram bot that will log any message it receives in chats or groups where it is allowed to see messages. 

For pulling messages en masse from a channel history, this isn't doable with standard bot permissions due to Telegram's privacy models. You might need other approaches, potentially involving user-bot accounts, which come with different sets of limitations and policy considerations.
