Erste Schritte mit der Service Control API

Auf dieser Seite werden die grundlegenden Schritte beschrieben, die erforderlich sind, um die Service Control API auf Ihrem lokalen Computer einzurichten und mit dem Befehl curl zu testen.

Ersteinrichtung

Die Service Control API arbeitet mit verwalteten Diensten zusammen. Um die Service Control API zu verwenden, müssen Sie zuerst einen verwalteten Dienst mithilfe der Service Management API erstellen. Weitere Informationen finden Sie unter Service Management – Erste Schritte.

Nachdem Sie einen verwalteten Dienst erstellt haben, müssen Sie folgende Schritte ausführen, bevor Sie die Service Control API über Ihren verwalteten Dienst verwenden.

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.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the 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:[e-mail].

   • Replace ROLE with each individual role.
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.

    Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the 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:[e-mail].

    • Replace ROLE with each individual role.

Mit curl testen

Definieren Sie zuerst einen praktischen Shell-Alias zum Aufrufen der Google REST APIs:

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

Die folgende Abfolge von Shell-Befehlen zeigt die Schritte für den Aufruf der Service Control API.

# 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"
}

Ergebnis nach Ausführung der vorherigen Schritte:

• Sie haben eine funktionsfähige lokale Testumgebung, in der Sie beliebige Google Cloud Platform APIs aufrufen können.
• Sie haben einen funktionsfähigen Dienst, den Sie mit der Service Management API und der Service Control API verwenden können.
• Sie haben ein Dienstkonto mit den entsprechenden Berechtigungen, das Sie für die Ausführung Ihres Dienstes verwenden können.
