Types

type LINEChannel

type LINEChannel struct {
	*channels.BaseChannel
	// contains filtered or unexported fields
}

LINEChannel implements the Channel interface for LINE Official Account using the LINE Messaging API with HTTP webhook for receiving messages and REST API for sending messages.

func NewLINEChannel

func NewLINEChannel(cfg config.LINEConfig, messageBus *bus.MessageBus) (*LINEChannel, error)

NewLINEChannel creates a new LINE channel instance.

func (*LINEChannel) Send

func (c *LINEChannel) Send(ctx context.Context, msg bus.OutboundMessage) error

Send sends a message to LINE. It first tries the Reply API (free) using a cached reply token, then falls back to the Push API.

func (*LINEChannel) SendMedia

func (c *LINEChannel) SendMedia(ctx context.Context, msg bus.OutboundMediaMessage) error

SendMedia implements the channels.MediaSender interface. LINE requires media to be accessible via public URL; since we only have local files, we fall back to sending a text message with the filename/caption. For full support, an external file hosting service would be needed.

func (*LINEChannel) ServeHTTP

func (c *LINEChannel) ServeHTTP(w http.ResponseWriter, r *http.Request)

ServeHTTP implements http.Handler for the shared HTTP server.

func (*LINEChannel) Start

func (c *LINEChannel) Start(ctx context.Context) error

Start initializes the LINE channel.

func (*LINEChannel) StartTyping

func (c *LINEChannel) StartTyping(ctx context.Context, chatID string) (func(), error)

StartTyping implements channels.TypingCapable using LINE's loading animation.

NOTE: The LINE loading animation API only works for 1:1 chats. Group/room chat IDs (starting with "C" or "R") are detected automatically; for these, a no-op stop function is returned without calling the API.

func (*LINEChannel) Stop

func (c *LINEChannel) Stop(ctx context.Context) error

Stop gracefully stops the LINE channel.

func (*LINEChannel) WebhookPath

func (c *LINEChannel) WebhookPath() string

WebhookPath returns the path for registering on the shared HTTP server.
