roughrider.cors

This package allows you to create a policy that can handle CORS. It can be used with any python framework as it's totally agnostic. It can cook response headers, even for preflight requests.

Example

from roughrider.cors.policy import CORSPolicy

cors = CORSPolicy(
    methods=['GET', 'POST'],
    allow_headers=['Accept-Encoding'],
    expose_headers=['Accept-Encoding'],
    max_age=19000
)

headers = list(cors.headers())

# Arguments for the preflight should be extracted from the request.
# depending on the type of framework you use (WSGI, ASGI...)
preflight_headers = list(cors.preflight(
    origin='http://example.com',
    acr_headers='X-Custom-Header, Accept-Encoding'
))
