Klien

Untuk mendapatkan sesuatu dari web:

 import aiohttp
import asyncio

async def main ():

    async with aiohttp . ClientSession () as session :
        async with session . get ( 'http://python.org' ) as response :

            print ( "Status:" , response . status )
            print ( "Content-type:" , response . headers [ 'content-type' ])

            html = await response . text ()
            print ( "Body:" , html [: 15 ], "..." )

asyncio . run ( main ())

Ini mencetak:

 Status: 200
Tipe konten: teks/html; rangkaian karakter=utf-8
Isi: <!doctype html> ...

Contoh penggunaan server sederhana:

 # examples/server_simple.py
from aiohttp import web

async def handle ( request ):
    name = request . match_info . get ( 'name' , "Anonymous" )
    text = "Hello, " + name
    return web . Response ( text = text )

async def wshandle ( request ):
    ws = web . WebSocketResponse ()
    await ws . prepare ( request )

    async for msg in ws :
        if msg . type == web . WSMsgType . text :
            await ws . send_str ( "Hello, {}" . format ( msg . data ))
        elif msg . type == web . WSMsgType . binary :
            await ws . send_bytes ( msg . data )
        elif msg . type == web . WSMsgType . close :
            break

    return ws


app = web . Application ()
app . add_routes ([ web . get ( '/' , handle ),
                web . get ( '/echo' , wshandle ),
                web . get ( '/{name}' , handle )])

if __name__ == '__main__' :
    web . run_app ( app )
