Communication between Ruby on Rails 3 Web application and C++ Desktop application

According to my requirement I need to provide a communication between a Desktop application developed on C++(QT Framework) and Web application developing on Rails 3.

The requirement is, User can able to upload/download files from Desktop application to Rails application. These files I need to save in live database.

For this requirement, I'm planning to develop an API(Possibly Web Service). First of all is it possible to complete this requiremen开发者_JS百科t through Web Services using SOAP/WSDL/REST.

Please let me know the different ways to achieve this.

Thanks,

Kalyan

Rails provides a really nice way of developing an API with it's supported REST protocol. This way you can easy develop a web front end while essentially completing the API at the same time, this way your desktop application can communicate via the API.

As long as you keep your code DRY(Don't Repeat Yourself), your API can co-exist within your same web project. This way you don't have two separate code projects to maintain. This will help with consistency.
