Python Requests Async IO

Python Requests is a popular Python library for making HTTP requests. While Requests is a synchronous library, it can be combined with Python's asyncio library to create asynchronous HTTP clients.

How to Use Asyncio With Requests

To use Requests with asyncio, you'll need to install the aiohttp library, which provides an async-friendly HTTP client. You can install aiohttp using pip:

pip install aiohttp

Once you've installed aiohttp, you can use it to make asynchronous HTTP requests with Requests. Here's an example:

import asyncio
import requests
from aiohttp import ClientSession

async def main():
    async with ClientSession() as session:
        async with session.get('') as response:
            print(await response.text())

loop = asyncio.get_event_loop()

In this code, we're first importing the necessary libraries: asyncio, requests, and ClientSession from aiohttp. We then define an async function called main(), which creates a new ClientSession object and sends an asynchronous HTTP request with the get() method.

To run this code, we create a new event loop with asyncio.get_event_loop() and call its run_until_complete() method with our main() function as an argument.


Using Python Requests with asyncio allows us to create asynchronous HTTP clients that can handle multiple requests simultaneously, improving performance and scalability. By combining the easy-to-use interface of Requests with the power of asyncio, we can make HTTP requests in an efficient and intuitive way.
