Service Control API 시작하기

이 페이지에서는 로컬 머신에서 Service Control API를 설정하고 curl 명령어를 사용하여 테스트하는 데 필요한 기본 단계를 설명합니다.

초기 설정

Service Control API는 관리형 서비스와 함께 사용됩니다. Service Control API를 사용하려면 먼저 Service Management API를 사용하여 관리형 서비스를 만들어야 합니다. 자세한 내용은 Service Management 시작하기를 참조하세요.

관리형 서비스를 만든 후에는 관리형 서비스에서 Service Control API를 사용하기 전에 다음 단계를 완료해야 합니다.

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
  2. Install the Google Cloud CLI.

  3. To initialize the gcloud CLI, run the following command: 

    gcloud init

  4. Create or select a Google Cloud project.

    • 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.

  5. Make sure that billing is enabled for your Google Cloud project.

  6. Enable the Service Control API: 

    gcloud services enable servicecontrol.googleapis.com

  7. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/servicemanagement.serviceController 

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE
    • Replace PROJECT_ID with your project ID.

    • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.

    • Replace ROLE with each individual role.
    8.
  8. Install the Google Cloud CLI.

  9. To initialize the gcloud CLI, run the following command: 

    gcloud init

  10. Create or select a Google Cloud project.

    • 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.

  11. Make sure that billing is enabled for your Google Cloud project.

  12. Enable the Service Control API: 

    gcloud services enable servicecontrol.googleapis.com

  13. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/servicemanagement.serviceController 

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE
    • Replace PROJECT_ID with your project ID.

    • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.

    • Replace ROLE with each individual role.
    14.

curl로 테스트

먼저 Google REST API를 호출하기 위한 간편한 셸 별칭을 정의합니다.

alias gcurl='curl -H "Authorization: Bearer $(gcloud auth print-access-token)" -H "Content-Type: application/json" '

다음 셸 명령어 시퀀스는 Service Control API를 호출하기 위한 점진적 단계를 보여줍니다.

# Call with invalid service name "invalid.com". For security and privacy
# reasons, the permission check typically happens before other checks.
$ gcurl -d '{}' https://servicecontrol.googleapis.com/v1/services/invalid.com:check
{
  "error": {
    "code": 403,
    "message": "Permission 'servicemanagement.services.check' denied on service 'invalid.com'.",
    "status": "PERMISSION_DENIED"
  }
}

# Call without proper permission on a service.
$ gcurl -d '{}' https://servicecontrol.googleapis.com/v1/services/servicecontrol.googleapis.com:check
{
  "error": {
    "code": 403,
    "message": "Permission 'servicemanagement.services.check' denied on service 'servicecontrol.googleapis.com'.",
    "status": "PERMISSION_DENIED"
  }
}

# Call with invalid request.
$ gcurl -d '{}' https://servicecontrol.googleapis.com/v1/services/endpointsapis.appspot.com:check
{
  "error": {
    "code": 400,
    "message": "Request contains an invalid argument.",
    "status": "INVALID_ARGUMENT"
  }
}

# This and following call assume that the service, operation name and
# project being checked are "endpointsapis.appspot.com",
# "google.example.hello.v1.HelloService.GetHello" and
# "endpointsapis-consumer" correspondingly.
# Change to the name of your managed service, operation, and project.
# Call with invalid request.
$ gcurl -d '{
  "operation": {
    "operationId": "123e4567-e89b-12d3-a456-426655440000",
    "consumerId": "project:endpointsapis-consumer",
    "startTime": "2016-06-12T22:00:15Z",
    "operationName": "google.example.hello.v1.HelloService.GetHello"
  }
}' https://servicecontrol.googleapis.com/v1/services/endpointsapis.appspot.com:check
{
  "checkErrors": [
  {
    "code": "SERVICE_NOT_ACTIVATED",
    "detail": "Service 'endpointsapis.appspot.com' is not enabled for consumer 'project:endpointsapis-consumer'."
  }
  ]
}

# Successful call to "services.check" method after the API is enabled for
# the project.
$ gcurl -d '{
  "operation": {
    "operationId": "123e4567-e89b-12d3-a456-426655440000",
    "consumerId": "project:endpointsapis-consumer",
    "startTime":"2016-07-31T05:20:00Z",
    "operationName":"google.example.hello.v1.HelloService.GetHello"
  }
}' https://servicecontrol.googleapis.com/v1/services/endpointsapis.appspot.com:check
{
  "operationId": "123e4567-e89b-12d3-a456-426655440000"
}

이전 단계를 완료한 후에는 다음과 같은 결과를 얻어야 합니다.

  • Google Cloud Platform API를 호출하는 데 사용할 수 있는 로컬 테스트 설정이 있으며 제대로 작동합니다.
  • Service Management API 및 Service Control API와 함께 사용할 수 있는 서비스가 있으며 제대로 작동합니다.
  • 서비스를 실행하는 데 사용할 수 있는 권한을 가진 서비스 계정이 있습니다.
