Key Features

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 middleware and pluggable routing.

Getting started

Client

To get something from the web:

.. code-block:: python

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())

This prints:

.. code-block::

Status: 200
Content-type: text/html; charset=utf-8
Body: <!doctype html> ...

Server

An example using a simple server:

.. code-block:: python

# 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)
