The library provides Etag support for aiohttp.web.
Most of the source code is ported from Tornado.
Install from PyPI:
pip install aiohttp-etagInstall requirement and launch tests:
pip install -r dev-requirements.txt
pytest testsA trivial usage example:
import asyncio
import time
import aiohttp_etag
from aiohttp import web
async def plain(request):
text = 'Hello aiohttp!'
return web.Response(text=text)
async def resource(request):
text = 'Hello aiohttp!'
return web.json_response({
'message': text,
})
async def dynamic_plain(request):
last_visit = time.time()
text = 'Last visited: {}'.format(last_visit)
return web.Response(text=text)
async def dynamic_resource(request):
last_visit = time.time()
return web.json_response({
'last_visit': last_visit,
})
async def chunked(request):
response = web.StreamResponse()
response.content_type = 'text/plain'
await response.prepare(request)
await response.write(b'OK')
await asyncio.sleep(2)
await response.write(b'GOOD')
await response.write_eof()
return response
async def make_app():
app = web.Application()
aiohttp_etag.setup(app)
app.router.add_get('/', plain)
app.router.add_get('/resource', resource)
app.router.add_get('/dynamic', dynamic_plain)
app.router.add_get('/dynamic/resource', dynamic_resource)
app.router.add_get('/chunked', chunked)
return app
web.run_app(make_app())
