Python Requests Post Async

Python requests module is a great tool for making HTTP requests from Python code. It provides an easy-to-use API for sending HTTP requests and handling the responses. One of the key features of the requests module is the ability to make asynchronous requests using the asyncio library.

Asyncio Overview

Asyncio is a Python library that provides a way to write asynchronous code using coroutines. Coroutines are functions that can be paused and resumed at specific points in the code. This allows for non-blocking I/O operations, which can greatly improve the performance of your code.

Making Async Requests with Requests

One way to make asynchronous requests with requests is to use the asyncio library. Here's an example:

import asyncio
import requests

async def make_request():
    response = await asyncio.get_event_loop().run_in_executor(None, requests.post, "https://example.com", data={"key": "value"})
    return response

response = asyncio.run(make_request())

In this example, we define a coroutine function called make_request. Inside this function, we use the asyncio.get_event_loop() function to get a reference to the current event loop. We then use the run_in_executor() method of the event loop to run the requests.post() function in a separate thread. This allows us to make the request without blocking the main thread of execution.

The await keyword is used to pause the execution of the coroutine until the request is complete. Once the request is complete, the response object is returned.

Other Options for Async Requests

There are other libraries available for making asynchronous HTTP requests in Python, such as aiohttp and treq. These libraries provide similar functionality to requests, but are specifically designed for use in asynchronous code.
