Python Requests not Wait for Response

As a developer, you may have encountered situations where you want to send a request using Python's requests library, but you don't want to wait for the response before moving on to the next task. This can be due to various reasons, such as wanting to improve the performance of your application or needing to send multiple requests simultaneously.

Using the Asynchronous Requests

One way to achieve this is by using asynchronous requests. Async requests allow you to send multiple requests at the same time without waiting for the response. This can be done using the asyncio library in Python. Here's an example:


import asyncio
import aiohttp

async def send_request(url):
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as response:
            return await response.text()

async def main():
    urls = ['https://example.com', 'https://google.com', 'https://facebook.com']
    tasks = []
    for url in urls:
        tasks.append(asyncio.ensure_future(send_request(url)))

    responses = await asyncio.gather(*tasks)
    print(responses)

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

In this example, we are using the aiohttp library to make asynchronous requests. We define a function send_request that takes in a URL and sends a GET request using the async with session.get() method. We then define a main function that sends requests to multiple URLs using the asyncio.gather() method. We create a list of tasks for each URL and add them to the tasks list. Finally, we use the asyncio.gather() method to execute all the tasks simultaneously and print the responses.

Using the Threading

Another way to achieve this is by using threads. In this method, you can send requests in a separate thread, which will not block the main thread. Here's an example:


import threading
import requests

def send_request(url):
    response = requests.get(url)
    print(response.text)

urls = ['https://example.com', 'https://google.com', 'https://facebook.com']
threads = []
for url in urls:
    thread = threading.Thread(target=send_request, args=(url,))
    threads.append(thread)
    thread.start()

In this example, we define a send_request function that takes in a URL and sends a GET request using the requests.get() method. We then create a list of threads for each URL and add them to the threads list. Finally, we start all the threads by calling the thread.start() method.

Conclusion

In conclusion, there are multiple ways to send Python requests without waiting for a response. You can use async requests with the aiohttp library or use threads to send requests in a separate thread. Choose the method that suits your requirements and application architecture.
