jsonp-proxy Mike Mayo <mike@overhrd.com> twitter: @greenisus Dead simple Sinatra app to make REST API calls and respond in a JSONP style. Example: http://localhost:4567/?jsonp=callback&u=https%3A//auth.api.rackspacecloud.com/v1.0 If you included proper headers, you would get something like this back: callback({ the.response.json }); Request params (all must be URL escaped): jsonp => callback(response); u => uri m => HTTP method (GET, POST, PUT, DELETE, HEAD, etc) default GET h => request headers hash in json, url encoded b => request body Callback argument looks like this: { status: 200, headers: { header: hash }, body: 'body text' }
