Python Requests Library Async

If you're working on a project that requires sending HTTP requests, then you've probably heard of the Python Requests library. Python Requests is a popular library used for making HTTP requests in Python. It provides an easy-to-use interface and can be used to send GET, POST, PUT, DELETE, and other types of HTTP requests.

However, when you're dealing with a large number of requests, it's often more efficient to use asynchronous programming techniques. This is where the Python Requests library Async comes into play.

What is Asynchronous Programming?

Asynchronous programming is a programming model that allows multiple tasks to run concurrently within a single thread. This means that instead of waiting for one task to complete before starting another, you can start multiple tasks at once and let them run in the background.

In Python, asynchronous programming is often achieved using the asyncio module. The asyncio module provides an event loop that can be used to manage multiple tasks running concurrently.

Using the Python Requests Library Async

To use the Python Requests library Async, you'll need to install the library using pip:


pip install requests-async

Once you've installed the library, you can use it in your Python code like this:


import asyncio
import requests_async

async def make_requests():
    urls = [
        'https://www.google.com',
        'https://www.facebook.com',
        'https://www.github.com',
    ]
    tasks = []
    for url in urls:
        tasks.append(asyncio.ensure_future(requests_async.get(url)))
    responses = await asyncio.gather(*tasks)
    for response in responses:
        print(response.status_code)

loop = asyncio.get_event_loop()
loop.run_until_complete(make_requests())

In this example, we first import the asyncio and requests_async libraries. We define a function called make_requests() that uses the requests_async library to send HTTP requests to three different URLs. We create a list of tasks for each URL, and then use asyncio.gather() to run all of the tasks concurrently. Finally, we loop through the responses and print the status code for each response.

Other Ways to Use the Python Requests Library Async

In addition to using asyncio, there are other ways to use the Python Requests library Async. For example, you can use the Grequests library, which is a Python library that allows you to send asynchronous HTTP requests using the Python Requests library. Grequests uses greenlets to achieve asynchronous behavior.

Another option is to use the aiohttp library, which is an asynchronous HTTP client/server library for Python. aiohttp can be used to send asynchronous HTTP requests and supports both client and server-side operations.
