- 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 middlewares and plugable 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], "...")
- loop = asyncio.get_event_loop()
- loop.run_until_complete(main())
- This prints:
- .. code-block::
- Status: 200
- Content-type: text/html; charset=utf-8
- Body: <!doctype html> ...
- Coming from `requests <https://requests.readthedocs.io/>`_ ? Read `why we need so many lines <https://aiohttp.readthedocs.io/en/latest/http_request_lifecycle.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)
