python-aiohttpHow to get JSON data using Python Aiohttp?

Using Python Aiohttp, you can get JSON data from a web server.

import aiohttp

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

async def main():
    async with aiohttp.ClientSession() as session:
        json_data = await fetch(session, 'https://example.com/data.json')
        print(json_data)

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

{
  "name": "John Doe",
  "age": 34
}

1. import aiohttp - imports the aiohttp library
2. async def fetch(session, url) - defines an asynchronous function to fetch the JSON data from the given URL
3. async with session.get(url) as response - uses the session to make a GET request to the given URL
4. return await response.json() - returns the response as JSON
5. async def main() - defines an asynchronous function to run the code
6. async with aiohttp.ClientSession() as session - creates a client session to make the request
7. json_data = await fetch(session, 'https://example.com/data.json') - calls the fetch function to get the JSON data from the given URL
8. print(json_data) - prints the JSON data
9. loop = asyncio.get_event_loop() - creates an event loop
10. loop.run_until_complete(main()) - runs the main function until it is complete
