Bibliotecas cliente de Cloud DLP

En esta página, se muestra cómo comenzar a usar las bibliotecas cliente de Cloud para la API de Cloud Data Loss Prevention. Obtén más información sobre las bibliotecas cliente de las API de Cloud, incluidas las API de Google anteriores y bibliotecas cliente en Explicación de las bibliotecas cliente.

Las bibliotecas cliente de Cloud DLP que se mencionan en esta página son compatibles con Compute Engine, el entorno flexible de App Engine, Google Kubernetes Engine y Cloud Functions. La biblioteca cliente de Cloud DLP para Java es compatible con Java 8 en el entorno estándar de App Engine.

Si usas Java 7 en el entorno estándar de App Engine o en el entorno estándar de App Engine con Go, PHP o Python, usa la interfaz REST para acceder a Cloud DLP.

Instala la biblioteca cliente

C#

Para obtener más información, consulta Configura un entorno de desarrollo de C#. Para compilar y ejecutar una muestra, abre el archivo de solución (Dlp.sln) con Visual Studio 2015 o posterior y compílalo.

Para obtener más información, consulta el archivo README.

Go

go get -u github.com/GoogleCloudPlatform/golang-samples/dlp

Java

Para obtener más información, consulta Configura un entorno de desarrollo de Java. Si usas Maven, agrega lo siguiente a tu archivo pom.xml:

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-dlp</artifactId>
    <version></version>
</dependency>

Si usas Gradle, agrega lo siguiente a tus dependencias:

compile group: 'com.google.cloud', name: 'google-cloud-dlp', version: ''

Node.js

Para obtener más información, consulta Configura un entorno de programación de Node.js.

npm install --save @google-cloud/dlp

PHP

composer require google/cloud-dlp

Nota: La biblioteca cliente de Cloud DLP requiere que instales y habilites la extensión de gRPC para PHP.

Python

Para obtener más información, consulta Configura un entorno de desarrollo de Python.

1. Instala pip y virtualenv si aún no lo hiciste. Puede que desees consultar la Guía de configuración del entorno de desarrollo de Python para Google Cloud Platform a fin de obtener las instrucciones.
2. Clona o descarga las muestras de documentos de Python Google Cloud Platform en GitHub.
3. Crea un virtualenv. Las muestras son compatibles con Python 2.7.x, 3.4 o superior.

   $ virtualenv env
   $ source env/bin/activate

4. Desde el directorio dlp en las muestras de documentos de Python de Google Cloud Platform clonadas o descomprimidas, instala las dependencias necesarias para ejecutar las muestras.

   $ pip install -r requirements.txt

Importante: Debes usar cd en el directorio dlp de las muestras de documentos de Python de Google Cloud Platform antes de ejecutar el comando anterior.

Ruby

Para obtener más información, consulta Configura un entorno de programación de Ruby.

gem install google-api-client

Cómo configurar la autenticación

Si quieres ejecutar la biblioteca cliente, primero debes configurar la autenticación. Para ello, crea una cuenta de servicio y configura una variable de entorno. Sigue los pasos que se indican a continuación a fin de configurar la autenticación. Para obtener más información, consulta la documentación de autenticación de GCP.

GCP Console

1. In the GCP Console, go to the Create service account key page.

   Go to the Create Service Account Key page
2. From the Service account list, select New service account.
3. In the Service account name field, enter a name.

4. From the Role list, select Project > Owner.

   Note: The Role field authorizes your service account to access resources. You can view and change this field later by using the GCP Console. If you are developing a production app, specify more granular permissions than Project > Owner. For more information, see granting roles to service accounts.
5. Click Create. A JSON file that contains your key downloads to your computer.

Command line

You can run the following commands using the Cloud SDK on your local machine, or in Cloud Shell.

1. Create the service account. Replace [NAME] with a name for the service account.

   gcloud iam service-accounts create [NAME]

2. Grant permissions to the service account. Replace [PROJECT_ID] with your project ID.

   gcloud projects add-iam-policy-binding [PROJECT_ID] --member "serviceAccount:[NAME]@[PROJECT_ID].iam.gserviceaccount.com" --role "roles/owner"

   Note: The Role field authorizes your service account to access resources. You can view and change this field later by using GCP Console. If you are developing a production app, specify more granular permissions than Project > Owner. For more information, see granting roles to service accounts.

3. Generate the key file. Replace [FILE_NAME] with a name for the key file.

   gcloud iam service-accounts keys create [FILE_NAME].json --iam-account [NAME]@[PROJECT_ID].iam.gserviceaccount.com

Provide authentication credentials to your application code by setting the environment variable GOOGLE_APPLICATION_CREDENTIALS. Replace [PATH] with the file path of the JSON file that contains your service account key, and [FILE_NAME] with the filename. This variable only applies to your current shell session, so if you open a new session, set the variable again.

Linux or macOS

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

For example:

export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/[FILE_NAME].json"

Windows

With PowerShell:

$env:GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

For example:

$env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads\[FILE_NAME].json"

With command prompt:

set GOOGLE_APPLICATION_CREDENTIALS=[PATH]

Usa la biblioteca cliente

En el siguiente ejemplo, se muestra cómo usar la biblioteca cliente.

Go
