A simple Sinatra extension to enable Cross Domain Resource Sharing (CORS) To see more on cross domain resource sharing, see https://developer.mozilla.org/En/HTTP_access_control
gem "sinatra-cross_origin", "~> 0.3.1"
To enable cross origin requests for all routes:
require 'sinatra'
require 'sinatra/cross_origin'
configure do
enable :cross_origin
end
To only enable cross origin requests for certain routes:
get '/cross_origin' do
cross_origin
"This is available to cross-origin javascripts"
end
You can set global options via the normal Sinatra set method:
set :allow_origin, :any
set :allow_methods, [:get, :post, :options]
set :allow_credentials, true
set :max_age, "1728000"
set :expose_headers, ['Content-Type']
You can change configuration options on the fly within routes with:
get '/custom' do
cross_origin :allow_origin => 'http://example.com',
:allow_methods => [:get],
:allow_credentials => false,
:max_age => "60"
"My custom cross origin response"
end
