Question

How can I make sinatra code respond to below GET method?

http://my.server.address/function?key1=value1&key2=value2&key3=value3

Thanks for your kindness.

Since the only thing in the path is ‘/function’, that’s the only thing you have to manage. The host will be dealt with by the server, the params by Sinatra (it makes them available through the params method) So we can get this running with this little bit of code:

require 'sinatra'
get '/function' do
  params.inspect
end

And when we run it locally on port 4567, then go to “http://localhost:4567/function?key1=value1&key2=value2&key3=value3”, it returns our inspected params as {"key1"=>"value1", "key2"=>"value2", "key3"=>"value3"}

As far as the “my.server.address”, that depends on how you’re hosting your application. If you have no experience here, the easiest way to get something like this working is to use Heroku.
