requests-cache
Requests-cache is a transparent persistent cache for requests (version >= 1.1.0) library.
Usage example
Just write:
import requests
import requests_cache
requests_cache.install_cache('demo_cache')And all responses with headers and cookies will be transparently cached to demo_cache.sqlite database. For example, following code will take only 1-2 seconds instead of 10, and will run instantly on next launch:
for i in range(10):
requests.get('http://httpbin.org/delay/1')It can be useful when you are creating some simple data scraper with constantly changing parsing logic or data format, and don’t want to redownload pages or write complex error handling and persistence.
Note
requests-cache ignores all cache headers, it just caches the data for the time you specify.
If you need library which knows how to use HTTP headers and status codes, take a look at httpcache and CacheControl.
