Introduzione all'API Service Control

Questa pagina descrive i passaggi di base necessari per configurare l'API Service Control sul computer locale e testarla utilizzando il comando curl.

Impostazione iniziale

L'API Service Control funziona con servizi gestiti. Per utilizzare API Service Control, devi prima creare un servizio gestito utilizzando l'API Service Management. Per ulteriori informazioni, consulta la guida introduttiva alla gestione dei servizi.

Dopo aver creato un servizio gestito, devi completare i seguenti passaggi prima di utilizzare l'API Service Control dal servizio gestito.

  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_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_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.

Test con curl

Per prima cosa, definisci un comodo alias di shell per chiamare le API REST Google:

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

La seguente sequenza di comandi shell illustra i passaggi incrementali da chiamare l'API Service Control.

# 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"
}

Dopo aver completato i passaggi precedenti:

  • Hai una configurazione di test locale funzionale che puoi utilizzare per chiamare qualsiasi API della piattaforma Google Cloud.
  • Disponi di un servizio funzionante che puoi usare con API Service Management e ai API Service Control.
  • Disponi di un account di servizio con le autorizzazioni corrette che puoi utilizzare per per eseguire il tuo servizio.
