@ 메뉴에서 타사 리소스 만들기

이 페이지에서는 Google Docs 사용자가 Google Docs 내의 서드 파티 서비스에서 지원 케이스 또는 프로젝트 작업과 같은 리소스를 만들 수 있는 Google Workspace 부가기능을 빌드하는 방법을 설명합니다.

Google Workspace 부가기능을 사용하면 Docs의 @ 메뉴에 서비스를 추가할 수 있습니다. 이 부가기능은 사용자가 Docs의 양식 대화상자를 통해 서비스에 리소스를 만들 수 있는 메뉴 항목을 추가합니다.

사용자가 리소스를 만드는 방법

Google Docs 문서 내에서 서비스에 리소스를 만들려면 문서에 @를 입력하고 @ 메뉴에서 서비스를 선택합니다.

사용자가 카드를 미리 봅니다.

사용자가 문서에 @를 입력하고 서비스를 선택하면 리소스를 만드는 데 필요한 양식 입력이 포함된 카드가 사용자에게 표시됩니다. 사용자가 리소스 만들기 양식을 제출하면 부가기능은 서비스에 리소스를 만들고 이 리소스를 가리키는 URL을 생성해야 합니다.

부가기능은 생성된 리소스의 문서에 칩을 삽입합니다. 사용자가 이 칩 위에 포인터를 가져가면 부가기능과 연결된 링크 미리보기 트리거가 호출됩니다. 부가기능이 링크 미리보기 트리거에서 지원하는 링크 패턴이 있는 칩을 삽입해야 합니다.

기본 요건

Apps Script

  • 사용자가 만드는 리소스의 링크 패턴에 대한 링크 미리보기를 지원하는 Google Workspace 부가기능 링크 미리보기가 포함된 부가기능을 빌드하려면 스마트 칩으로 링크 미리보기를 참고하세요.

Node.js

  • 사용자가 만드는 리소스의 링크 패턴에 대한 링크 미리보기를 지원하는 Google Workspace 부가기능 링크 미리보기가 포함된 부가기능을 빌드하려면 스마트 칩으로 링크 미리보기를 참고하세요.

Python

  • 사용자가 만드는 리소스의 링크 패턴에 대한 링크 미리보기를 지원하는 Google Workspace 부가기능 링크 미리보기가 포함된 부가기능을 빌드하려면 스마트 칩으로 링크 미리보기를 참고하세요.

Java

  • 사용자가 만드는 리소스의 링크 패턴에 대한 링크 미리보기를 지원하는 Google Workspace 부가기능 링크 미리보기가 포함된 부가기능을 빌드하려면 스마트 칩으로 링크 미리보기를 참고하세요.

부가기능의 리소스 만들기 설정

이 섹션에서는 다음 단계를 포함하여 부가기능의 리소스 생성을 설정하는 방법을 설명합니다.

  1. 부가기능의 배포 리소스 또는 매니페스트 파일에서 리소스 생성을 구성합니다.
  2. 사용자가 서비스 내에서 리소스를 만드는 데 필요한 양식 카드를 작성합니다.
  3. 사용자가 양식을 제출할 때 리소스를 만드는 함수가 실행되도록 양식 제출을 처리합니다.

리소스 생성 구성

리소스 생성을 구성하려면 부가기능의 배포 리소스 또는 매니페스트 파일에서 다음 섹션과 필드를 지정합니다.

  1. docs 필드의 addOns 섹션에서 runFunction가 포함된 createActionTriggers 트리거를 구현합니다. (이 함수는 다음 섹션인 양식 카드 빌드에서 정의합니다.)

    createActionTriggers 트리거에서 지정할 수 있는 필드에 대한 자세한 내용은 Apps Script 매니페스트 파일 또는 다른 런타임의 배포 리소스 참조 문서를 확인하세요.

  2. 사용자가 부가기능을 승인하여 리소스를 만들 수 있도록 oauthScopes 필드에 https://www.googleapis.com/auth/workspace.linkcreate 범위를 추가합니다. 특히 이 범위를 사용하면 부가기능이 사용자가 리소스 생성 양식에 제출하는 정보를 읽고 이 정보를 기반으로 문서에 스마트 칩을 삽입할 수 있습니다.

예를 들어 다음 지원 케이스 서비스의 리소스 생성을 구성하는 배포 리소스의 addons 섹션을 참조하세요.

{
  "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"
        }
      ]
    }
  }
}

이 예에서 Google Workspace 부가기능을 사용하면 사용자가 지원 케이스를 만들 수 있습니다. 각 createActionTriggers 트리거에는 다음 필드가 있어야 합니다.

  • 고유 ID
  • Docs @ 메뉴에 표시되는 텍스트 라벨
  • @ 메뉴의 라벨 텍스트 옆에 표시되는 아이콘을 가리키는 로고 URL
  • Apps Script 함수 또는 카드를 반환하는 HTTP 엔드포인트를 참조하는 콜백 함수

양식 카드 만들기

Docs @ 메뉴에서 서비스의 리소스를 만들려면 createActionTriggers 객체에 지정한 함수를 구현해야 합니다.

사용자가 메뉴 항목 중 하나와 상호작용하면 상응하는 createActionTriggers 트리거가 실행되고 콜백 함수가 리소스를 만들기 위한 양식 입력이 포함된 카드를 표시합니다.

지원되는 요소 및 작업

카드 인터페이스를 만들려면 위젯을 사용하여 사용자가 리소스를 만드는 데 필요한 정보와 입력을 표시합니다. 대부분의 Google Workspace 부가기능 위젯 및 작업은 지원되지만 다음과 같은 예외가 있습니다.

  • 카드 바닥글은 지원되지 않습니다.
  • 알림이 지원되지 않습니다.
  • 탐색의 경우 updateCard 탐색만 지원됩니다.

양식 입력이 포함된 카드의 예

다음 예는 사용자가 @ 메뉴에서 지원 케이스 만들기를 선택할 때 카드를 표시하는 Apps Script 콜백 함수를 보여줍니다.

createCaseInputCard 함수는 다음 카드를 렌더링합니다.

양식 입력이 있는 카드

카드에는 텍스트 입력, 드롭다운 메뉴, 체크박스가 포함됩니다. 또한 생성 양식의 제출을 처리하기 위해 다른 함수를 실행하는 onClick 작업이 있는 텍스트 버튼도 있습니다.

사용자가 양식을 작성하고 만들기를 클릭하면 부가기능은 양식 입력을 onClick 작업 함수(이 예에서는 submitCaseCreationForm)로 전송합니다. 그러면 부가기능은 입력을 검증하고 이를 사용하여 서드 파티 서비스에서 리소스를 만들 수 있습니다.

양식 제출 처리

사용자가 생성 양식을 제출하면 onClick 작업과 연결된 함수가 실행됩니다. 이상적인 사용자 환경을 위해 부가기능은 성공적인 양식 제출과 잘못된 양식 제출을 모두 처리해야 합니다.

성공적인 리소스 생성 처리

부가기능의 onClick 함수는 서드 파티 서비스에 리소스를 만들고 이 리소스를 가리키는 URL을 생성합니다.

칩 생성을 위해 리소스의 URL을 문서에 다시 전달하려면 onClick 함수가 링크를 가리키는 renderActions.action.links의 요소 1개 배열과 함께 SubmitFormResponse를 반환해야 합니다. 링크 제목은 생성된 리소스의 제목을 나타내야 하며 URL은 해당 리소스를 가리켜야 합니다.

다음 예는 생성된 리소스의 SubmitFormResponse를 보여줍니다.

SubmitFormResponse가 반환되면 모달 대화상자가 닫히고 부가기능이 문서에 칩을 삽입합니다. 사용자가 이 칩 위에 포인터를 가져가면 연결된 링크 미리보기 트리거가 호출됩니다. 부가기능에서 링크 미리보기 트리거에서 지원하지 않는 링크 패턴이 있는 칩을 삽입하지 않아야 합니다.

오류 처리

사용자가 잘못된 필드가 포함된 양식을 제출하려고 하면 부가기능은 링크와 함께 SubmitFormResponse를 반환하는 대신 updateCard 탐색을 사용하여 오류를 표시하는 렌더링 작업을 반환해야 합니다. 이렇게 하면 사용자가 자신이 잘못한 것을 확인하고 다시 시도할 수 있습니다. Apps Script의 경우 updateCard(card)를, 다른 런타임의 경우 updateCard를 참조하세요. 알림 및 pushCard 탐색은 지원되지 않습니다.

오류 처리의 예

다음 예는 사용자가 양식을 제출할 때 호출되는 코드를 보여줍니다. 입력이 잘못된 경우 카드가 업데이트되고 오류 메시지가 표시됩니다. 입력이 유효하면 부가기능은 생성된 리소스의 링크와 함께 SubmitFormResponse를 반환합니다.

전체 예: 지원 케이스 부가기능

다음 예는 회사의 지원 케이스 링크를 미리 보고 사용자가 Google Docs 내에서 지원 케이스를 만들 수 있는 Google Workspace 부가기능을 보여줍니다.

이 예시는 다음을 수행합니다.

  • Docs @ 메뉴에서 지원 케이스를 만들기 위한 양식 필드가 포함된 카드를 생성합니다.
  • 양식 입력의 유효성을 검사하고 잘못된 입력에 대한 오류 메시지를 반환합니다.
  • 생성된 지원 케이스의 이름과 링크를 Docs 문서에 스마트 칩으로 삽입합니다.
  • 지원 케이스의 링크(예: https://www.example.com/support/cases/1234)를 미리 봅니다. 스마트 칩에 아이콘이 표시되고 미리보기 카드에는 케이스 이름, 우선순위, 설명이 포함되어 있습니다.
