Question

I have an async_sinatra application that uses eventmachine in the following way:

aget '/test' do
    EM.defer { body 'test: ' + params[:foo] }
end

When I request the url as /test?foo=bar it yields test: bar, however when I declare the path as aget '/test/:foo' do and attempt to use params[:foo] the request never returns.

Why can’t I use in-url parameters in async_sinatra?

Answer 1

Yes but you need to declare your route like this:

aget '/test/:foo' do
