HTTP

The HTTP binding. The emitted member is http, and every object carries bindingVersion: 0.3.0.

@httpOperation

extern dec httpOperation(target: Operation, config: valueof AsyncAPIHttpOperationBinding);

Field	Type	Required
method	string	no
query	unknown	no

Apply it to an operation that carries @send or @receive.

method is one of GET, PUT, POST, PATCH, DELETE, HEAD, OPTIONS, CONNECT and TRACE.

query is a Schema Object of type object with a properties key. AsyncAPI states both requirements.

@httpMessage

extern dec httpMessage(target: Model, config: valueof AsyncAPIHttpMessageBinding);

Field	Type	Required
headers	unknown	no
statusCode	int32	no

Apply it to a model that also carries @message.

headers is a Schema Object of type object with a properties key.

statusCode is a status code from RFC 9110, so it is between 100 and 599. AsyncAPI states that it applies only to a message named by an Operation Reply Object. The emitter does not check that rule, because it spans two objects.
