An alpha version of a plugin for bottle to handle CORS (Cross Origin
Resource Sharing). It adds a Access-Control-Allow-Origin
header and
registeres routes to serve OPTIONS requests for your endpoints (request
preflighting).
Copy the cors_plugin.py somewhere into your project. ie:
cp cors_plugin.py <your_project>/plugins
then you have to import and register the plugin:
from plugins.cors_plugin import RequestPreflightPlugin
request_preflight_plugin = RequestPreflightPlugin( allow_origin = '*',
preflight_methods = [ 'GET', 'POST', 'PUT', 'DELETE' ],
ttl = 3600 )
request_handler.install( request_preflight_plugin )
allow_origin
will be the value of the Access-Control-Allow-Origin
header.
preflight_methods
lists the methods/HTTP verbs that you want to have preflighted by default.
ttl
will be the value of the Access-Control-Max-Age
in the OPTIONS response.
All routes that you have will get an OPTIONS route registered that will serve the preflight response.
If you want to exclude a route from preflighting you have to skip the plugin:
@route( "/path",
skip = [ request_preflight_plugin ] )
def do_stuff:
pass
- make the OPTION preflighting optional?
