hikari.api.interaction_server

Provides an interface for Interaction REST server API implementations to follow.

ListenerT module-attribute

ListenerT = Union[Callable[['_InteractionT_co'], Awaitable['_ResponseT_co']], Callable[['_InteractionT_co'], AsyncGenerator['_ResponseT_co', None]]]

Type hint of a Interaction server's listener callback.

This should be an async callback which takes in one positional argument which subclasses hikari.interactions.base_interactions.PartialInteraction and may return an instance of the relevant hikari.api.special_endpoints.InteractionResponseBuilder subclass for the provided interaction type which will instruct the server on how to respond.

Note

For the standard implementations of hikari.api.special_endpoints.InteractionResponseBuilder see hikari.impl.special_endpoints.

InteractionServer

Bases: ABC

Interface for an implementation of an interactions compatible REST server.

get_listener abstractmethod

get_listener(interaction_type: type[_InteractionT_co]) -> Optional[ListenerT[_InteractionT_co, InteractionResponseBuilder]]

Get the listener registered for an interaction.

PARAMETER	DESCRIPTION
interaction_type	Type of the interaction to get the registered listener for. TYPE: type[_InteractionT_co]

RETURNS	DESCRIPTION
typing.Optional[ListenersT[hikari.interactions.base_interactions.PartialInteraction, hikari.api.special_endpoints.InteractionResponseBuilder]	The callback registered for the provided interaction type if found, else None.

on_interaction abstractmethod async

on_interaction(body: bytes, signature: bytes, timestamp: bytes) -> Response

Handle an interaction received from Discord as a REST server.

PARAMETER	DESCRIPTION
body	The interaction payload. TYPE: bytes
signature	Value of the "X-Signature-Ed25519" header used to verify the body. TYPE: bytes
timestamp	Value of the "X-Signature-Timestamp" header used to verify the body. TYPE: bytes

RETURNS	DESCRIPTION
Response	Instructions on how the REST server calling this should respond to the interaction request.

set_listener abstractmethod

set_listener(interaction_type: type[_InteractionT_co], listener: Optional[ListenerT[_InteractionT_co, InteractionResponseBuilder]], /, *, replace: bool = False) -> None

Set the listener callback for this interaction server.

PARAMETER	DESCRIPTION
interaction_type	The type of interaction this listener should be registered for. TYPE: type[_InteractionT_co]
listener	The asynchronous listener callback to set or None to unset the previous listener. An asynchronous listener can be either a normal coroutine or an async generator which should yield exactly once. This allows sending an initial response to the request, while still later executing further logic. TYPE: Optional[ListenerT[_InteractionT_co, InteractionResponseBuilder]]
replace	Whether this call should replace the previously set listener or not. TYPE: bool DEFAULT: False

RAISES	DESCRIPTION
TypeError	If replace is False when a listener is already set.

Response

Bases: Protocol

Protocol of the data returned by hikari.api.interaction_server.InteractionServer.on_interaction.

This is used to instruct lower-level REST server logic on how it should respond.

charset property

charset: Optional[str]

Charset of the response's payload, if applicable.

content_type property

content_type: Optional[str]

Content type of the response's payload, if applicable.

files property

files: Sequence[Resource[AsyncReader]]

Up to 10 files that should be included alongside a JSON response.

headers property

headers: Optional[MutableMapping[str, str]]

Headers that should be added to the response if applicable.

payload property

payload: Optional[bytes]

Payload to provide in the response.

status_code property

status_code: int

Status code that should be used to respond.
