python-aiohttpHow to use Python Aiohttp and FastAPI?

Python Aiohttp and FastAPI are two popular web frameworks used for building asynchronous web applications.

import aiohttp
from fastapi import FastAPI

app = FastAPI()

@app.get("/")
async def root():
    async with aiohttp.ClientSession() as session:
        async with session.get('http://example.com') as resp:
            return await resp.text()

The example code above shows how to use both Aiohttp and FastAPI together. The code creates a FastAPI application and defines a route that uses Aiohttp to make a GET request to an external URL.

Code explanation

1. import aiohttp - imports the Aiohttp library
2. from fastapi import FastAPI - imports the FastAPI library
3. app = FastAPI() - creates a FastAPI application
4. @app.get("/") - defines a route for the application
5. async with aiohttp.ClientSession() as session - creates an Aiohttp client session
6. async with session.get('http://example.com') as resp - makes a GET request to an external URL
7. return await resp.text() - returns the response text

The output of the example code is the response text from the external URL.
