Python Rate Limiter based on Redis.

Project description

https://travis-ci.org/EvoluxBR/python-redis-rate-limit.svg?branch=master

This lib offers an abstraction of a Rate Limit algorithm implemented on top of Redis >= 2.6.0.

Example: 10 requests per second

from redis_rate_limit import RateLimit, TooManyRequests
try:
  with RateLimit(resource='users_list', client='192.168.0.10', max_requests=10):
    return '200 OK'
except TooManyRequests:
  return '429 Too Many Requests'

Example: 600 requests per minute

from redis_rate_limit import RateLimit, TooManyRequests
try:
  with RateLimit(resource='users_list', client='192.168.0.10', max_requests=600, expire=60):
    return '200 OK'
except TooManyRequests:
  return '429 Too Many Requests'

Example: 100 requests per hour

from redis_rate_limit import RateLimit, TooManyRequests
try:
  with RateLimit(resource='users_list', client='192.168.0.10', max_requests=100, expire=3600):
    return '200 OK'
except TooManyRequests:
  return '429 Too Many Requests'

Example: you can also setup a factory to use it later

from redis_rate_limit import RateLimiter, TooManyRequests
limiter = RateLimiter(resource='users_list', max_requests=100, expire=3600)
try:
  with limiter.limit(client='192.168.0.10'):
    return '200 OK'
except TooManyRequests:
  return '429 Too Many Requests'

Example: you can also pass an optional Redis Pool

import redis
from redis_rate_limit import RateLimit, TooManyRequests
redis_pool = redis.ConnectionPool(host='127.0.0.1', port=6379, db=0)
try:
  with RateLimit(resource='users_list', client='192.168.0.10', max_requests=10, redis_pool=redis_pool):
    return '200 OK'
except TooManyRequests:
  return '429 Too Many Requests'
