How to set headers in an aiohttp request in Python?

// plain

To set headers in an aiohttp request in Python, you can use the add_headers method. This method takes a dictionary of headers as an argument. For example:

import aiohttp

async with aiohttp.ClientSession() as session:
    async with session.get('http://example.com', headers={'User-Agent': 'My custom user agent'}) as response:
        print(response.status)

Output example

200

The code above sets the User-Agent header to My custom user agent and prints the response status code.

The code consists of the following parts:

1. import aiohttp - imports the aiohttp library
2. async with aiohttp.ClientSession() as session - creates a client session
3. async with session.get('http://example.com', headers={'User-Agent': 'My custom user agent'}) as response - sends a GET request to http://example.com with the User-Agent header set to My custom user agent
4. print(response.status) - prints the response status code
