The aiohttp library is a popular asynchronous HTTP client/server framework for Python. It allows you to make HTTP requests without blocking your application, perfect for building highly concurrent or asynchronous services.
To make a basic HTTP GET request with aiohttp:
import aiohttp
async with aiohttp.ClientSession() as session:
async with session.get('http://example.com') as response:
print(response.status)
print(await response.text())
Some key points:
You can pass various parameters like headers, data, timeouts etc to customise the requests:
async with session.get(url, params={'key':'value'}, headers={}, data=b'') as response:
# customised GET request
To post JSON data:
import json
data = {'key': 'value'}
async with session.post(url, json=data) as response:
# POST with json
print(await response.text())
Some tips when making requests with aiohttp:
The aiohttp library handles a lot of complexity like HTTP connections, timeouts and pooling for you. With its simple API focused on async/await, it is a pleasure to make HTTP requests without blocking your Python applications. Give it a try!
