Sensitive Data Protection 用戶端程式庫

本頁說明如何開始使用 Cloud Data Loss Prevention API 適用的 Cloud 用戶端程式庫。有了用戶端程式庫,您可以透過支援的語言,更輕鬆地存取Google Cloud API。雖然您可以直接向伺服器發出原始要求來使用Google Cloud API,但用戶端程式庫提供簡化功能,可大幅減少需要編寫的程式碼數量。

如要進一步瞭解 Cloud 用戶端程式庫和舊版 Google API 用戶端程式庫,請參閱「用戶端程式庫說明」。

Cloud Data Loss Prevention API (DLP API) 是 Sensitive Data Protection 的一部分。Compute Engine、App Engine 彈性環境、Google Kubernetes Engine 和 Cloud Run 函式支援本頁所述的 Sensitive Data Protection 用戶端程式庫。App Engine 標準環境上的 Java 8 支援 Java 適用的 Sensitive Data Protection 用戶端程式庫。

如果您在 App Engine 標準環境上使用 Java 7,或將 App Engine 標準環境與 Go、PHP 或 Python 搭配使用,請使用 REST 介面存取 Sensitive Data Protection。

安裝用戶端程式庫

C#

如要建構及執行範例,請使用 Visual Studio 2015 以上版本,開啟解決方案檔案 (Dlp.sln) 並建構範例。

詳情請參閱 README

詳情請參閱「設定 C# 開發環境」。

Go

go get cloud.google.com/go/dlp

詳情請參閱「設定 Go 開發環境」。

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.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.78.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

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

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

implementation 'com.google.cloud:google-cloud-dlp:3.91.0'

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

libraryDependencies += "com.google.cloud" % "google-cloud-dlp" % "3.91.0"

If you're using Visual Studio Code or IntelliJ, 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.

詳情請參閱「設定 Java 開發環境」。

Node.js

npm install @google-cloud/dlp

詳情請參閱「設定 Node.js 開發環境」。

PHP

composer require google/cloud-dlp

詳情請參閱「在 Google Cloud 上使用 PHP」。

Python

  1. 如果您沒有 pipvirtualenv,請先安裝這兩個程式。如需操作說明,請參閱 Python 開發環境設定指南 Google Cloud
  2. 前往 GitHub 複製或下載 Google Cloud Python 文件範例
  3. 建立 virtualenv。範例與 Python 2.7.x 和 3.4 以上版本相容。
    $ python -m venv dlp
    $ source dlp/bin/activate
  4. 從已複製或解壓縮的 Google Cloud Python Docs Samples 目錄下的 dlp 目錄,安裝執行範例所需的依附元件。
    $ pip install -r requirements.txt

Ruby

gem install google-api-client

詳情請參閱「設定 Ruby 開發環境」。

設定驗證方法

為驗證向 Google Cloud API 發出的呼叫,用戶端程式庫支援應用程式預設憑證 (ADC);程式庫會在定義的一組位置中尋找憑證,並使用這些憑證驗證向 API 發出的要求。有了 ADC,無需修改應用程式程式碼,就能在各種環境 (例如本機開發環境或正式環境),為應用程式提供憑證。

在正式環境中,設定 ADC 的方式取決於服務和背景。詳情請參閱「設定應用程式預設憑證」。

在本機開發環境中,您可以使用與 Google 帳戶相關聯的憑證設定 ADC:

  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.

    登入畫面會隨即顯示。登入後,您的憑證會儲存在 ADC 使用的本機憑證檔案中。

使用用戶端程式庫

以下範例將說明用戶端程式庫的使用方法。
