Tworzenie zasobów innych firm za pomocą menu @

Na tej stronie wyjaśniamy, jak utworzyć dodatek do Google Workspace, który umożliwia użytkownikom Dokumentów Google tworzenie zasobów, takich jak zgłoszenie do zespołu pomocy lub zadanie w projekcie, w usłudze innej firmy z poziomu Dokumentów Google.

Za pomocą dodatku do Google Workspace możesz dodać swoją usługę do menu @ w Dokumentach. Dodatek dodaje pozycje menu, które umożliwiają użytkownikom tworzenie zasobów w usłudze za pomocą okna formularza w Dokumentach.

Jak użytkownicy tworzą zasoby

Aby utworzyć zasób w swojej usłudze z poziomu dokumentu Dokumentów Google, użytkownik wpisz @ w dokumencie i wybierz usługę z menu @:

Użytkownik wyświetla podgląd karty

Gdy użytkownicy wpiszą @ w dokumencie i wybiorą Twoją usługę, wyświetli się im karta zawierająca dane wejściowe formularza potrzebne do utworzenia zasobu. Gdy użytkownik prześle formularz tworzenia zasobu, dodatek powinien utworzyć zasób w Twojej usłudze i wygenerować adres URL, który do niego prowadzi.

Dodatek wstawia element do dokumentu dla utworzonego zasobu. Gdy użytkownik przytrzyma wskaźnik na tym elemencie, wywoła on powiązany z dodatkiem aktywator podglądu linku. Sprawdź, czy dodatek wstawia elementy ze wzorcami linków obsługiwanymi przez reguły podglądu linku.

Wymagania wstępne

Google Apps Script

Node.js

Python

Java

Skonfiguruj tworzenie zasobów dla dodatku

W tej sekcji opisujemy, jak skonfigurować tworzenie zasobów dla dodatku:

  1. Skonfiguruj tworzenie zasobów w zasobie wdrożenia dodatku lub w pliku manifestu.
  2. Utwórz karty formularzy, których użytkownicy potrzebują do tworzenia zasobów w usłudze.
  3. Obsługuj przesyłanie formularzy, aby funkcja, która tworzy zasób, działała w momencie przesyłania formularza przez użytkownika.

Skonfiguruj tworzenie zasobów

Aby skonfigurować tworzenie zasobów, określ te sekcje i pola w zasobie wdrożenia lub pliku manifestu dodatku:

  1. W sekcji addOns w polu docs zaimplementuj regułę createActionTriggers zawierającą runFunction. Tę funkcję definiujesz w sekcji Tworzenie kart formularzy.

    Informacje o tym, jakie pola możesz określić w aktywatorze createActionTriggers, znajdziesz w dokumentacji dotyczącej plików manifestu Apps Script lub zasobów wdrażania w innych środowiskach wykonawczych.

  2. W polu oauthScopes dodaj zakres https://www.googleapis.com/auth/workspace.linkcreate, aby użytkownicy mogli autoryzować dodatek do tworzenia zasobów. Konkretnie ten zakres umożliwia dodatekowi odczytywanie informacji przesłanych przez użytkowników w formularzu tworzenia zasobów i wstawianie elementu inteligentnego do dokumentu na podstawie tych informacji.

Przykład: zapoznaj się z sekcją addons zasobu wdrożenia, który konfiguruje tworzenie zasobów dla tej usługi zgłoszeń do zespołu pomocy:

{
  "oauthScopes": [
    "https://www.googleapis.com/auth/workspace.linkpreview",
    "https://www.googleapis.com/auth/workspace.linkcreate"
  ],
  "addOns": {
    "docs": {
      "linkPreviewTriggers": [
        ...
      ],
      "createActionTriggers": [
        {
          "id": "createCase",
          "labelText": "Create support case",
          "localizedLabelText": {
            "es": "Crear caso de soporte"
          },
          "runFunction": "createCaseInputCard",
          "logoUrl": "https://www.example.com/images/case.png"
        }
      ]
    }
  }
}

W tym przykładzie dodatek do Google Workspace umożliwia użytkownikom tworzenie zgłoszeń do zespołu pomocy. Każdy aktywator createActionTriggers musi zawierać te pola:

  • Unikalny identyfikator.
  • Etykieta tekstowa wyświetlana w menu Dokumentów @
  • Adres URL logo wskazujący ikonę wyświetlaną obok tekstu etykiety w menu @
  • funkcję wywołania zwrotnego, która odwołuje się do funkcji Apps Script lub do punktu końcowego HTTP, która zwraca kartę

Tworzenie kart formularzy

Aby utworzyć zasoby w usłudze z poziomu menu Dokumenty @, musisz zaimplementować wszystkie funkcje podane w obiekcie createActionTriggers.

Gdy użytkownik wchodzi w interakcję z jednym z elementów menu, uruchamia się odpowiedni aktywator createActionTriggers, a jego funkcja wywołania zwrotnego przedstawia kartę z danymi wprowadzonymi przez formularz, aby utworzyć zasób.

Obsługiwane elementy i działania

Aby utworzyć interfejs karty, użyj widżetów, aby wyświetlać informacje i dane wejściowe potrzebne użytkownikom do utworzenia zasobu. Większość widżetów i działań dodatków do Google Workspace jest obsługiwanych z tymi wyjątkami:

  • Stopki kart nie są obsługiwane.
  • Powiadomienia nie są obsługiwane.
  • W przypadku nawigacji obsługiwana jest tylko nawigacja updateCard.

Przykład karty z polami do wprowadzania danych w formularzu

Poniższy przykład pokazuje funkcję wywołania zwrotnego Apps Script, która wyświetla kartę, gdy użytkownik wybierze Utwórz zgłoszenie do zespołu pomocy z menu @:

Funkcja createCaseInputCard renderuje tę kartę:

Karta z polami do wpisywania formularza

Karta zawiera tekst, menu i pole wyboru. Zawiera też przycisk tekstowy z działaniem onClick, które uruchamia inną funkcję do obsługi przesłania formularza tworzenia.

Gdy użytkownik wypełni formularz i kliknie Utwórz, dodatek wyśle dane wejściowe formularza do funkcji działania onClick (w naszym przykładzie o nazwie submitCaseCreationForm). Wtedy dodatek może zweryfikować dane wejściowe i użyć ich do utworzenia zasobu w usłudze zewnętrznej.

Obsługa przesłanych formularzy

Gdy użytkownik prześle formularz tworzenia, funkcja powiązana z działaniem onClick zostanie uruchomiona. Aby zadbać o wygodę użytkowników, dodatek powinien obsługiwać zarówno udane, jak i błędne formularze.

Wykonaj instrukcje tworzenia zasobów

Funkcja onClick dodatku powinna utworzyć zasób w usłudze zewnętrznej i wygenerować kierujący do niego adres URL.

Aby przekazać adres URL zasobu z powrotem do Dokumentów w celu utworzenia elementu, funkcja onClick powinna zwracać wartość SubmitFormResponse z jednoelementową tablicą w komponencie renderActions.action.links, która wskazuje link. Tytuł linku powinien reprezentować tytuł utworzonego zasobu, a adres URL powinien wskazywać ten zasób.

W tym przykładzie pokazano SubmitFormResponse w przypadku utworzonego zasobu:

Google Apps Script

 * 
 * @param {string} title The title of the link to insert.

 * @return {!SubmitFormResponse} The resulting submit form response.

Po zwróceniu SubmitFormResponse okno modalne zostanie zamknięte, a dodatek wstawi element do dokumentu. Gdy użytkownicy przytrzymują wskaźnik na tym elemencie, wywołuje on powiązany aktywator podglądu linku. Upewnij się, że dodatek nie wstawia elementów ze wzorcami linków nieobsługiwanymi przez reguły podglądu linku.

Obsługa błędów

Jeśli użytkownik spróbuje przesłać formularz z nieprawidłowymi polami, zamiast zwracać błąd SubmitFormResponse z linkiem, dodatek powinien zwrócić działanie renderowania, które wyświetla błąd przy użyciu nawigacji updateCard. Dzięki temu użytkownik może sprawdzić, co nie wyszło, i spróbować jeszcze raz. Więcej informacji o środowisku wykonawczym znajdziesz w sekcji updateCard(card), a o innych środowiskach wykonawczych – na updateCard. Powiadomienia i nawigacje w usłudze pushCard nie są obsługiwane.

Przykład obsługi błędów

Poniższy przykład przedstawia kod, który jest wywoływany, gdy użytkownik przesyła formularz. Jeśli dane wejściowe są nieprawidłowe, karta zostanie zaktualizowana i wyświetli komunikaty o błędach. Jeśli dane wejściowe są prawidłowe, dodatek zwraca SubmitFormResponse z linkiem do utworzonego zasobu.

Pełny przykład: dodatek do zgłoszenia do zespołu pomocy

Poniższy przykład pokazuje dodatek do Google Workspace, który wyświetla podgląd linków do zgłoszeń do zespołu pomocy firmy i umożliwia użytkownikom tworzenie zgłoszeń do zespołu pomocy z poziomu Dokumentów Google.

W tym przykładzie:

  • Generuje kartę z polami formularza w celu utworzenia zgłoszenia do zespołu pomocy z menu Dokumentów @.
  • Sprawdza dane wejściowe formularza i zwraca komunikaty o błędach w przypadku nieprawidłowych danych wejściowych.
  • Wstawia nazwę utworzonego zgłoszenia do zespołu pomocy i link do dokumentu w Dokumentach jako element inteligentny.
  • Wyświetla podgląd linku do zgłoszenia do zespołu pomocy, np. https://www.example.com/support/cases/1234. Element inteligentny wyświetla ikonę, a karta podglądu zawiera nazwę zgłoszenia, priorytet i opis.
