python-aiohttpHow to make a GET request with Python Aiohttp?

Making a GET request with Python Aiohttp is easy and straightforward.

import aiohttp

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    async with aiohttp.ClientSession() as session:
        html = await fetch(session, 'http://python.org')
        print(html)

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())

The output of the example code will be the HTML content of the page http://python.org.

Code explanation

1. import aiohttp - imports the aiohttp library
2. async def fetch(session, url) - defines an asynchronous function to make a GET request
3. async with session.get(url) as response - makes a GET request to the specified URL
4. return await response.text() - returns the response as text
5. async with aiohttp.ClientSession() as session - creates a client session
6. html = await fetch(session, 'http://python.org') - calls the fetch function to make a GET request
7. print(html) - prints the response
8. loop = asyncio.get_event_loop() - creates an event loop
9. loop.run_until_complete(main()) - runs the main function until it is complete
