Commonly assumed
Request::getPayload() follows Content-Type and merges all request inputs, while passing an already encoded JSON string to JsonResponse sends that document unchanged.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- assert Request::getPayload prefers a non-empty parsed form bag over query and raw JSON, returns a defensive InputBag clone, and InputBag::get rejects nested values that InputBag::all retrieves
- assert Request::toArray independently decodes the raw JSON body with out-of-range integers preserved as strings, while getPayload decodes raw JSON even under text/plain and rejects scalar JSON
- assert HeaderBag canonicalizes underscore and uppercase spellings, appends only when set replacement is false, and get returns the first value
- assert JsonResponse constructor encodes a PHP string but fromJsonString preserves a pre-encoded document, default encoding hex-escapes HTML-sensitive characters, and an explicit media type is retained
- assert Response::prepare removes a HEAD body while retaining explicit Content-Length and removes body plus entity headers for a 204 response
