ProblemJsonConverter

class ProblemJsonConverter(json: Json = Json) : ContentConverter(source)

Reads and writes application/problem+json bodies for ContentNegotiation.

Thin by design. The encoding lives in ProblemSerializer in core; this only delegates. Registering it is a convenience, not a correctness requirement: an application's pre-existing json() converter produces the same bytes, since Problem carries ProblemSerializer as its own serializer.

Parameters

json

governs formatting only (indentation and the like); the document's shape comes from the serializer attached to Problem.

Constructors

ProblemJsonConverter

constructor(json: Json = Json)

Functions

deserialize

open suspend override fun deserialize(charset: Charset, typeInfo: TypeInfo, content: ByteReadChannel): Any?

Reads a Problem from the request body, or returns null if the receiving type is anything else, leaving the body to the next converter.

serialize

open suspend override fun serialize(contentType: ContentType, charset: Charset, typeInfo: TypeInfo, value: Any?): OutgoingContent?

Writes value as application/problem+json, or null if it isn't a Problem. That is the interface's way of saying "not mine", so ContentNegotiation tries the next converter.
