which language to use for creating a RESTFul web service?

Question

I will have to create API calls for my system to be exposed to the outside world. Which language would be the best fit?

I will have to create proper authentication (OAuth) and I am looking to build in such a way that it is very reusable and extensible.

If I had to choose between Python and Ruby, which one should I and why? (considering my experience is 5/10 on both the languages)

Answer 1

You are probably not looking only for a language but also for frameworks and tools to help you build your services.

If you are comfortable with ruby check out rails and its implementation or REST. If you prefer Java you can have a look at Restlet or Apache Wink. Sure there are plenty more options out there but it depends on your needs. If you can elaborate a bit more, you might get a more appropriate answer.

Answer 2

Windows Communication Foundation (WCF) is used for creating web services in .NET.

Answer 3

Here is a language matrix of REST frameworks:

Answer 4

I'll throw in my vote for using Sinarta (framework). It is incredibly simple, uses REST verbs to respond to actions and is fast. I have written a couple of services, one hosted on Heroku (free) that acts as an exchange between a desktop db and web app. The other is on our local net that controls a DAQ (digital acquisition) board. I don't think either are more than 100-125 LOC. Neither took me more than an hour to write (with tests).
