Kemampuan permukaan (Dialogflow)

Jelajahi di Dialogflow

Klik Continue untuk mengimpor contoh Kemampuan platform di Dialogflow. Kemudian, ikuti langkah-langkah di bawah ini untuk men-deploy dan menguji sampel:

  1. Masukkan nama agen dan buat agen Dialogflow baru untuk contoh.
  2. Setelah agen selesai mengimpor, klik Buka agen.
  3. Dari menu navigasi utama, buka Fulfillment.
  4. Aktifkan Inline Editor, lalu klik Deploy. Editor berisi kode contoh.
  5. Dari menu navigasi utama, buka Integrations, lalu klik Google Assistant.
  6. Di jendela modal yang muncul, aktifkan Perubahan pratinjau otomatis, lalu klik Uji untuk membuka simulator Action.
  7. Pada simulator, masukkan Talk to my test app untuk menguji sampel.
Lanjutkan

Action Anda dapat muncul di berbagai platform, termasuk platform audio saja (smart speaker) serta platform audio & layar (seperti layar smart dan perangkat seluler).

Untuk mendesain dan membuat percakapan yang berfungsi dengan baik di semua platform, gunakan kemampuan platform untuk mengontrol dan menentukan cakupan percakapan dengan benar.

Kemampuan platform untuk Actions

Actions on Google memungkinkan Anda mengontrol apakah pengguna dapat memanggil Action Anda atau tidak, berdasarkan platform yang mereka gunakan. Jika pengguna mencoba memanggil Action Anda di platform yang tidak didukung, mereka akan menerima pesan error yang memberi tahu bahwa perangkat mereka tidak didukung.

Anda menentukan dukungan platform Action dalam project Action Anda.

Action Anda dapat muncul di berbagai platform yang didukung Asisten, seperti smartphone (Android dan iOS) dan perangkat Google Home.

Kemampuan platform runtime

Anda dapat memenuhi pengalaman pengguna dengan kemampuan platform runtime dengan dua cara utama:

  • Pencabangan respons - Memberikan respons yang berbeda kepada pengguna, tetapi memiliki struktur dan alur yang sama untuk percakapan Anda di platform yang berbeda. Misalnya, Action cuaca mungkin menampilkan kartu dengan gambar di ponsel dan memutar file audio di Google Home, tetapi alur percakapannya sama di seluruh platform.

  • Percabangan percakapan - Menampilkan percakapan yang benar-benar berbeda di setiap platform kepada pengguna. Misalnya, jika Anda mem-build aplikasi pemesanan makanan, Anda mungkin ingin menyediakan alur pemesanan ulang di Google Home, tetapi alur perakitan keranjang lengkap di ponsel. Untuk melakukan pencabangan percakapan, cakupan pemicu intent di Dialogflow ke kemampuan platform tertentu dengan konteks Dialogflow. Intent Dialogflow yang sebenarnya tidak akan dipicu kecuali jika kemampuan platform tertentu terpenuhi.

  • Percakapan multi-platform - Mempresentasikan percakapan kepada pengguna di satu platform yang bertransisi ke platform lain di tengah percakapan. Misalnya, jika pengguna memanggil Action Anda dengan gambar di platform audio saja seperti Google Home, Anda dapat membuat Action untuk mencari platform lain yang memiliki kemampuan visual dan memindahkan percakapan ke sana jika memungkinkan.

Pencabangan respons

Setiap kali fulfillment Anda menerima permintaan dari Asisten Google, Anda dapat mengkueri kemampuan platform berikut (misalnya, Google Home atau ponsel Android):

Node.js

const hasScreen =
  conv.surface.capabilities.has('actions.capability.SCREEN_OUTPUT');
  // OR conv.screen;
const hasAudio =
  conv.surface.capabilities.has('actions.capability.AUDIO_OUTPUT');

Percabangan percakapan

Anda dapat menyiapkan intent Dialogflow agar hanya memicu kemampuan tertentu dengan konteks Dialogflow yang telah ditetapkan. Setiap kali intent dicocokkan, Dialogflow akan otomatis menghasilkan konteks dari serangkaian kemampuan platform yang disediakan perangkat. Anda dapat menentukan satu atau beberapa konteks ini sebagai "konteks input" untuk intent Anda. Hal ini memungkinkan Anda untuk memblokir pemicu intent berdasarkan modalitas.

Misalnya, jika Anda hanya ingin intent dipicu di perangkat dengan output layar, Anda dapat menetapkan konteks input pada intent menjadi actions_capability_screen_output.

Konteks berikut tersedia:

  • actions_capability_audio_output - Perangkat memiliki speaker.
  • actions_capability_screen_output - Perangkat memiliki layar tampilan output.
  • actions_capability_media_response_audio - Perangkat mendukung pemutaran konten media.
  • actions_capability_web_browser - Perangkat mendukung browser web. (Kemampuan ini saat ini tidak tersedia untuk layar smart.)

Berikut adalah contoh intent yang hanya akan dipicu pada platform dengan layar:

Percakapan multiplatform

Kapan saja selama alur Action, Anda dapat memeriksa apakah pengguna memiliki platform lain dengan kemampuan tertentu. Jika platform lain dengan kemampuan yang diminta tersedia, Anda dapat mentransfer percakapan saat ini ke platform baru tersebut.

Alur untuk transfer permukaan akan bekerja sebagai berikut:

  1. Memeriksa apakah pengguna memiliki platform yang tersedia

    Di pengendali webhook, Anda dapat mengkueri apakah pengguna memiliki platform yang tersedia dengan kemampuan tertentu. Perhatikan bahwa platform ini harus dikaitkan ke Akun Google yang sama dengan platform sumber.

    Node.js

    const screenAvailable =
  conv.available.surfaces.capabilities.has(
    'actions.capability.SCREEN_OUTPUT');
    index.js

    Java

    String screen = Capability.SCREEN_OUTPUT.getValue();
boolean screenAvailable = false;
for (Surface surface : request.getAvailableSurfaces()) {
  for (com.google.api.services.actions_fulfillment.v2.model.Capability capability :
      surface.getCapabilities()) {
    if (capability.getName().equals(screen)) {
      screenAvailable = true;
      break;
    }
  }
}

  2. Permintaan untuk mentransfer pengguna ke platform baru

    Jika ada platform yang tersedia dengan kemampuan yang diperlukan, Action Anda harus bertanya kepada pengguna apakah mereka ingin mentransfer percakapan.

    Node.js

    if (conv.screen) {
  conv.ask(`You're already on a screen device.`);
  conv.ask('What else would you like to try?');
  conv.ask(new Suggestions([
    'Current Capabilities',
    'Check Audio Capability',
    'Check Screen Capability',
    'Check Media Capability',
    'Check Web Capability',
  ]));
  return;
} else if (screenAvailable) {
  const context =
    `Let's move you to a screen device for cards and other visual responses`;
  const notification = 'Try your Action here!';
  const capabilities = ['actions.capability.SCREEN_OUTPUT'];
  return conv.ask(new NewSurface({context, notification, capabilities}));
} else {
  conv.ask('It looks like there is no screen device ' +
    'associated with this user.');

  3. Menangani respons pengguna

    Berdasarkan respons pengguna terhadap permintaan Anda, Action Anda akan memfasilitasi penyerahan atau kembali kontrol percakapan ke platform asli. Apa pun itu, permintaan berikutnya ke endpoint Anda akan berisi intent actions.intent.NEW_SURFACE, sehingga Anda harus mem-build intent yang terpicu pada peristiwa tersebut dengan pengendali yang sesuai di webhook Anda. Dalam kode pengendali, Anda harus memeriksa apakah transfer berhasil atau tidak.

    Node.js

    app.intent('Transfer Surface - NEW_SURFACE', (conv, input, newSurface) => {
  if (newSurface.status === 'OK') {
    conv.ask('Welcome to a screen device!');
