This allows mime types in the form text/html, text/*, or */*
This required a few minor test/code changes where previously nil was
used as a mime string.
When a `get` method called with `as: :json` and `params: nil` or
`params: false` (explicitly or implicitly)
`RequestEncoder#encode_params` converts it into a `null` or `false`
value which includes a unexpected `null=` or `false` query string into
request URL. From now on `RequestEncoder#encode_params` checks whether
`params` is nil or not otherwise returns.
Move down `nil` conversion guard
Update CHANGELOG.md
Instead of appending a format to the request, it's much better
to just pass a more appropriate accept header. Rails will figure
out the format from that instead.
This allows devs to use `:as` on routes that don't have a format.
Introduce an `IdentityEncoder` to avoid `if request_encoder`,
essentially a better version of the purpose of the `WWWFormEncoder`.
One that makes conceptual sense on GET requests too.
Fixes#27144.
Previously we'd only assign a response parser when a request came through
Action Dispatch integration tests. This made calls to `parsed_body` when a TestResponse
was manually instantiated — though own doing or perhaps from a framework — unintentionally
blow up because no parser was set at that time.
The response can lookup a parser entirely through its own ivars. Extract request encoder to
its own file and assume that a viable content type is present at TestResponse instantiation.
Since the default response parser is a no-op, making `parsed_body` equal to `body`, no
exceptions will be thrown.
