Bibliotecas de cliente da Proteção de dados confidenciais

Esta página mostra como começar a usar as bibliotecas cliente da nuvem para a API Cloud Data Loss Prevention. As bibliotecas cliente facilitam o acesso às Google Cloud APIs a partir de um idioma suportado. Embora possa usar as Google Cloud APIs diretamente fazendo pedidos não processados ao servidor, as bibliotecas cliente oferecem simplificações que reduzem significativamente a quantidade de código que tem de escrever.

Leia mais acerca das bibliotecas cliente da nuvem e das bibliotecas cliente das APIs Google mais antigas em Bibliotecas cliente explicadas.

A API Cloud Data Loss Prevention (API DLP) faz parte da Proteção de dados confidenciais. As bibliotecas de cliente da Proteção de dados confidenciais mencionadas nesta página são suportadas no Compute Engine, no App Engine – ambiente flexível, no Google Kubernetes Engine e nas funções do Cloud Run. A biblioteca cliente da proteção de dados confidenciais para Java é suportada no Java 8 no ambiente padrão do App Engine.

Se estiver a usar o Java 7 no ambiente padrão do App Engine ou o ambiente padrão do App Engine com Go, PHP ou Python, use a interface REST para aceder à proteção de dados confidenciais.

Instale a biblioteca de cliente

C#

Para criar e executar um exemplo, abra o ficheiro de solução (Dlp.sln) com o Visual Studio 2015 ou posterior e crie-o.

Para mais informações, consulte o ficheiro README.

Para mais informações, consulte o artigo Configurar um ambiente de desenvolvimento C#.

Go

go get cloud.google.com/go/dlp

Para mais informações, consulte o artigo Configurar um ambiente de desenvolvimento Go.

Java

If you are using Maven, add the following to your pom.xml file. For more information about BOMs, see The Google Cloud Platform Libraries BOM.

If you are using Gradle, add the following to your dependencies:

implementation 'com.google.cloud:google-cloud-dlp:3.77.0'

If you are using sbt, add the following to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-dlp" % "3.77.0"

If you're using Visual Studio Code, IntelliJ, or Eclipse, you can add client libraries to your project using the following IDE plugins:

The plugins provide additional functionality, such as key management for service accounts. Refer to each plugin's documentation for details.

Para mais informações, consulte o artigo Configurar um ambiente de desenvolvimento Java.

Node.js

npm install @google-cloud/dlp

Para mais informações, consulte o artigo Configurar um ambiente de desenvolvimento do Node.js.

PHP

composer require google/cloud-dlp

Para mais informações, consulte o artigo Usar o PHP no Google Cloud.

Python

  1. Instale o pip e o virtualenv se ainda não os tiver. Pode consultar o guia de configuração do ambiente de desenvolvimento do Python Google Cloud para ver instruções.
  2. Clone ou transfira os Google Cloud exemplos de documentos Python no GitHub.
  3. Crie um virtualenv. Os exemplos são compatíveis com o Python 2.7.x e o 3.4 e superior.
    $ python -m venv dlp
    $ source dlp/bin/activate
  4. No diretório dlp no diretório Google Cloud Python Docs Samples clonado ou descomprimido, instale as dependências necessárias para executar os exemplos.
    $ pip install -r requirements.txt

Ruby

gem install google-api-client

Para mais informações, consulte o artigo Configurar um ambiente de desenvolvimento Ruby.

Configure a autenticação

Para autenticar chamadas para Google Cloud APIs, as bibliotecas cliente suportam Credenciais padrão da aplicação (ADC); as bibliotecas procuram credenciais num conjunto de localizações definidas e usam essas credenciais para autenticar pedidos para a API. Com o ADC, pode disponibilizar credenciais à sua aplicação numa variedade de ambientes, como desenvolvimento local ou produção, sem ter de modificar o código da aplicação.

Para ambientes de produção, a forma como configura o ADC depende do serviço e do contexto. Para mais informações, consulte o artigo Configure as Credenciais padrão da aplicação.

Para um ambiente de desenvolvimento local, pode configurar o ADC com as credenciais associadas à sua Conta Google:

  1. Install the Google Cloud CLI. After installation, initialize the Google Cloud CLI by running the following command:

    gcloud init

    If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

  2. If you're using a local shell, then create local authentication credentials for your user account:

    gcloud auth application-default login

    You don't need to do this if you're using Cloud Shell.

    If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

    É apresentado um ecrã de início de sessão. Depois de iniciar sessão, as suas credenciais são armazenadas no ficheiro de credenciais local usado pelo ADC.
