gcloud 도구를 사용하여 감정 분석 수행

이 페이지에서는 Google Cloud SDK를 사용하여 Cloud Natural Language API를 시작하는 방법을 설명합니다.

Google Cloud 콘솔에서 이 태스크에 대한 단계별 안내를 직접 수행하려면 둘러보기를 클릭합니다.

시작하기 전에

  1. Sign in to your Google Account.

    If you don't already have one, sign up for a new account.

  2. Install the Google Cloud CLI.

  3. 외부 ID 공급업체(IdP)를 사용하는 경우 먼저 제휴 ID로 gcloud CLI에 로그인해야 합니다.

  4. gcloud CLI를 초기화하려면, 다음 명령어를 실행합니다. 

    gcloud init

  5. Create or select a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

  6. Verify that billing is enabled for your Google Cloud project.

  7. Enable the Cloud Natural Language API:

    Roles required to enable APIs

    To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles. 

    gcloud services enable language.googleapis.com

  8. Install the Google Cloud CLI.

  9. 외부 ID 공급업체(IdP)를 사용하는 경우 먼저 제휴 ID로 gcloud CLI에 로그인해야 합니다.

  10. gcloud CLI를 초기화하려면, 다음 명령어를 실행합니다. 

    gcloud init

  11. Create or select a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

  12. Verify that billing is enabled for your Google Cloud project.

  13. Enable the Cloud Natural Language API:

    Roles required to enable APIs

    To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles. 

    gcloud services enable language.googleapis.com

    14. 항목 분석 요청 만들기

    gcloud

    gcloud 명령줄 도구를 사용하여 analyze-entities 명령어를 호출하고 --content 플래그를 사용하여 분석할 텍스트를 지정합니다. 
    gcloud ml language analyze-entities --content="Michelangelo Caravaggio, Italian painter, is known for 'The Calling of Saint Matthew'."

    명령줄

    curl을 사용하여 documents:analyzeEntities 메서드에 POST 요청을 하고 다음 예시와 같이 적절한 요청 본문을 제공합니다.

    이 예시에서는 gcloud auth application-default print-access-token 명령어를 사용하여 프로젝트를 설정할 때 만든 서비스 계정에 대한 액세스 토큰을 가져옵니다.

    curl -X POST \
  -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
  -H "Content-Type: application/json; charset=utf-8" \
 "https://language.googleapis.com/v1/documents:analyzeEntities" \
  --data "{
  'document':{
    'type':'PLAIN_TEXT',
    'content':'Michelangelo Caravaggio, Italian painter, is known for
              \'The Calling of Saint Matthew\'.'
  },
  'encodingType':'UTF8'
}"
