常见的想当然

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.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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
