Usage

sdk functions

$this->context->sdk('replyText', [$event['replyToken'], 'hello']);

Initialize

In your webhook entry point

public function __construct()
{
    $context = app('LINEBotContext');
}
...
public function entryPoint(Request $request)
{
    $lineMsg = $request->all();
    $events = collect($lineMsg['events']);
    $events->map(function($event) {
        $this->context->setContext($event);

        ... do whatever you want...
    });
}

Remember bot session

Use event queue is recommended, see app samples

// after setContext
event(new SaveLineBotSessionEvent($event));

State handling

Need Redis running in your enviorment

• init state

$this->context->initState([
    'status' => 1,
    'isAuth' => ['departA' => true, 'departB' => false]
    ]);
// must execute after setContext
$this->context->buildState();

• set state

$this->context->setState(['status' => 2]);

• get state

$this->context->getState('isAuth.departA');

• reset state

$this->context->resetState();

$this->context->setPushTo(string $userId|$groupId|$roomId);

$this->context->pushButtonTemplate(string $altText,array $template)

• confirm

$this->context->pushConfirmTemplate(string $altText,array $template)

• carousel

$this->context->pushCarouselTemplate(string $altText,array $template)

• image carousel

// example
$this->context->isTextMessage();
