func HandleEvent

func HandleEvent(ctx context.Context, t string, data []byte) (interface{}, error)

HandleEvent support other module call TODO the full project info is not in context so query and set here. this impl is for support other module, which is temporary. And it will be deprecated when rpc/http is ready

Types

type EventReq

type EventReq struct {
	// Channel message channel named (intact project name)
	Channel string `in:"path"  name:"channel"`
	// EventType used for filter strategies created in w3b before
	EventType string `in:"query" name:"eventType,omitempty"`
	// EventID unique id for tracing event under channel
	EventID string `in:"query" name:"eventID,omitempty"`
	// Timestamp event time when publisher do send
	Timestamp int64 `in:"query" name:"timestamp,omitempty"`
	// Payload event payload (binary only)
	Payload bytes.Buffer `in:"body" mime:"stream"`
}

func (*EventReq) IsDataPush

type EventRsp

type EventRsp struct {
	// Channel intact project name
	Channel string `json:"channel"`
	// PublisherID publisher(device) unique id in w3b node
	PublisherID types.SFID `json:"publisherID"`
	// PublisherKey publisher(device) mn unique id of this device
	PublisherKey string `json:"publisherKey"`
	// EventID same as EventReq.EventID
	EventID string `json:"eventID"`
	// Results result for each wasm invoke, which hits strategies.
