O que costuma-se supor

Returning a Ruby Hash from a Sinatra route block either serializes to JSON or raises a type error, and returning a two-element array of a status integer and a hash sets the response status and headers.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

Contrato

• assert a bare Hash returned from a route is treated as an Enumerable body yielding key-value array pairs with text/html rather than serializing to JSON
• assert returning a status integer and a headers Hash in a two-element array pops the Hash as the body and leaves response headers unset
• assert returning a three-element array unpacks the first element as status, the last as body, and the middle as response headers
• assert returning a bare Integer status code sets the HTTP response status and resets the response body to empty
• assert returning an Array of Strings is treated as an Enumerable streaming body with 200 OK because the first element is not an Integer
• assert returning a Symbol is ignored by route dispatch and leaves the response body empty
• assert returning a custom object with only to_s is ignored while an Enumerable defining each streams yielded chunks
• assert calling the body helper and returning nil retains the explicitly set body while returning an Integer wipes it
• assert halt with a status integer and a Hash pops the Hash as the response body with no headers set
