aiohttp-ratelimiter
aiohttp-ratelimiter is a rate limiter for the aiohttp.web framework. This is a new library and we are always looking for people to contribute. If you see something wrong with the code or want to add a feature, please create a pull request on our github.
Install from git
python -m pip install git+https://github.com/JGLTechnologies/aiohttp-ratelimiter
Install from pypi
python -m pip install aiohttp-ratelimiter
Example
from aiohttp import web
from aiohttplimiter import default_keyfunc, Limiter
app = web.Application()
routes = web.RouteTableDef()
limiter = Limiter(keyfunc=default_keyfunc)
@routes.get("/")
# This endpoint can only be requested 1 time per second per IP address
@limiter.limit("1/1")
async def home(request):
return web.Response(text="test")
app.add_routes(routes)
web.run_app(app)
You can exempt an IP from rate limiting using the exempt_ips kwarg.
from aiohttplimiter import Limiter, default_keyfunc
from aiohttp import web
app = web.Application()
routes = web.RouteTableDef()
# 192.168.1.245 is exempt from rate limiting.
# Keep in mind that exempt_ips takes a set not a list.
limiter = Limiter(keyfunc=default_keyfunc, exempt_ips={"192.168.1.245"})
@routes.get("/")
@limiter.limit("1/1")
async def test(request):
return web.Response(text="test")
app.add_routes(routes)
web.run_app(app)
You can create your own error handler by using the error_handler kwarg.
from aiohttplimiter import Allow, RateLimitExceeded, Limiter, default_keyfunc
from aiohttp import web
def handler(request: web.Request, exc: RateLimitExceeded):
# If for some reason you want to allow the request, return aiohttplimitertest.Allow().
if some_condition:
return Allow()
return web.Response(text="Too many requests", status=429)
limiter = Limiter(keyfunc=default_keyfunc, error_handler=handler)
If multiple paths use one handler like this:
@routes.get("/")
@routes.get("/home")
@limiter.limit("5/1")
def home(request):
return web.Response(text="Hello")
Then they will have separate rate limits. To prevent this use the path_id kwarg.
@routes.get("/")
@routes.get("/home")
@limiter.limit("5/1", path_id="home")
def home(request):
return web.Response(text="Hello")
If you want to use Redis instead, use the RedisLimiter class.
from aiohttplimiter import RedisLimiter, default_keyfunc
limiter = RedisLimiter(keyfunc=default_keyfunc, uri="redis://:[email protected]:port")
RedisLimiter is still being tested and might not be stable for production.
