Cross Origin POST Requests - dirkgroenen/mopidy-mopify GitHub Wiki

As most developers know it isn't possible to make POST requests in Javascript to an other domain without having to setup extra headers.

During developing I needed to send some POST requests to Echonest and Spotify. In both cases the browser returned the CORS error message. Time to start thinking about a solution since I really needed those POST requests. The result: an extra, online, page.

###How it works I've again used my online http:/mopify.bitlabs.nl/ page to create POST requests.

This time the solution was a bit easier. Instead of sending a post request to the service, I'm sending a GET request to my own server which holds the POST data as query variables. When the http://mopify.bitlabs.nl/api/post/ page is opened it will create a POST request using CURL based on the given parameters. The result is then placed on the page surrounded by the callback.
