What is the most elegant way to return a simple value in json format?
I'm triying to expose some data with a webservice that returns different json text based on the requested URL.
For some requests, the output is clear for me, because I'm returning objects, arrays of data, or a mixture. But for simple values, I don't know what is the most elegant way of returning the value.
For example, let's say I'm requesting http://host.com/last-client-id
Should I return
["1000"] - an array with one element? {"id": "1000"} - an object with the name of the value? "1000" - a simple string? What do you think?
