"Accept" header is not being taken into account

[icapuccio]

I wasn't able to get a JSON/XML response using the "Accept" header. The response's content type is always text/plain

The only way right now is through URI extensions. I'm using Rails 5.0.6

This looks like an issue with rails itself, as I am using the standard respond_to which according to rails doc https://api.rubyonrails.org/v5.0.6/classes/ActionController/MimeResponds.html :
"(Rails determines the desired response format from the HTTP Accept header submitted by the client.)"

I can reproduce your error using curl as well as the online https://reqbin.com/req/c-vdhoummp/curl-get-json-example test

This makes me curious!

Just checked health_check on an old rails 2.3.18 site, and it has the same issue ... Checked a rails 5.0 site resource index page, and it worked!! (though its using view selection at that point, not responds_to) ...

@icapuccio I have no idea why respond_to is not paying attention to the Accept header. Anyone have an idea?
