- Supports both client and server side of HTTP protocol.
- Supports both client and server Web-Sockets out-of-the-box and avoids Callback Hell.
- Provides Web-server with middlewares and pluggable routing.
To get something from the web:
import aiohttp
import asyncio
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())An example using a simple server:
# 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__':
