Making Asynchronous HTTP Requests in Python

Feb 3, 2024 ยท 1 min read

The Python Requests library provides a simple interface for making HTTP requests. By default, Requests makes synchronous requests, blocking execution until a response is received. However, Requests supports making asynchronous requests using threads or processes.

Using Threads

To make Requests concurrent using threads, use the requests.get() method inside threads:

import requests
import threading

def request():
  response = requests.get('https://example.com')
  print(response.status_code)

threads = []
for _ in range(10):
  t = threading.Thread(target=request) 
  threads.append(t)
  t.start()

for t in threads:
  t.join()

This allows sending multiple requests simultaneously in separate threads.

Using Processes

For more parallelism, processes can be used instead of threads. The code is similar, just use multiprocessing.Process instead of threading.Thread.

Hope this gives you some ideas on making Python requests concurrent!
