Library klien Sensitive Data Protection

Halaman ini menunjukkan cara memulai Library Klien Cloud untuk Cloud Data Loss Prevention API. Library klien mempermudah akses Google Cloud API dari bahasa yang didukung. Meskipun Anda dapat menggunakan Google Cloud API secara langsung dengan membuat permintaan mentah ke server, library klien memberikan penyederhanaan yang secara signifikan mengurangi jumlah kode yang perlu Anda tulis.

Baca selengkapnya tentang Library Klien Cloud dan Library Klien Google API yang lebih lama di Penjelasan library klien.

Cloud Data Loss Prevention API (DLP API) adalah bagian dari Sensitive Data Protection. Library klien Perlindungan Data Sensitif yang disebutkan di halaman ini didukung di Compute Engine, App Engine - Lingkungan Fleksibel, Google Kubernetes Engine, dan fungsi Cloud Run. Library klien Sensitive Data Protection untuk Java didukung di Java 8 di lingkungan standar App Engine.

Jika Anda menggunakan Java 7 di lingkungan standar App Engine, atau lingkungan App Engine - Standar dengan Go, PHP, atau Python, gunakan Antarmuka REST untuk mengakses Perlindungan Data Sensitif.

Menginstal library klien

C#

Untuk mem-build dan menjalankan contoh, buka file solusi (Dlp.sln) dengan Visual Studio 2015 atau yang lebih baru, lalu build.

Untuk informasi selengkapnya, lihat README.

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan C#.

Go

go get cloud.google.com/go/dlp

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan 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.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>

  </dependency>
</dependencies>

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

implementation 'com.google.cloud:google-cloud-dlp:3.57.0'

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

libraryDependencies += "com.google.cloud" % "google-cloud-dlp" % "3.57.0"

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

• Cloud Code for VS Code
• Cloud Code for IntelliJ
• Cloud Tools for Eclipse

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

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Java.

Node.js

npm install --save @google-cloud/dlp

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Node.js.

PHP

composer require google/cloud-dlp

Catatan: Library klien Perlindungan Data Sensitif mengharuskan Anda menginstal dan mengaktifkan Ekstensi gRPC untuk PHP.

Untuk informasi selengkapnya, lihat Menggunakan PHP di Google Cloud.

Python

1. Instal pip dan virtualenv jika Anda belum memilikinya. Anda dapat melihat Panduan Penyiapan Lingkungan Pengembangan Python untuk Google Cloud untuk mendapatkan petunjuk.
2. Clone atau download Contoh Dokumen Python Google Cloud di GitHub.
3. Buat virtualenv. Contoh kompatibel dengan Python 2.7.x dan 3.4 serta yang lebih tinggi.

   $ python -m venv dlp
   $ source dlp/bin/activate

4. Dari direktori dlp dalam direktori Contoh Dokumen Python Google Cloud yang di-clone atau diekstrak, instal dependensi yang diperlukan untuk menjalankan contoh.

   $ pip install -r requirements.txt

Penting: Anda harus cd ke direktori dlp Contoh Dokumen Python Google Cloud sebelum menjalankan perintah sebelumnya.

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Python.

Ruby

gem install google-api-client

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Ruby.

Menyiapkan autentikasi

Untuk mengautentikasi panggilan ke Google Cloud API, library klien mendukung Kredensial Default Aplikasi (ADC); library ini mencari kredensial dalam kumpulan lokasi yang ditentukan dan menggunakan kredensial tersebut untuk mengautentikasi permintaan ke API. Dengan ADC, Anda dapat menyediakan kredensial untuk aplikasi di berbagai lingkungan, seperti pengembangan lokal atau produksi, tanpa perlu mengubah kode aplikasi.

Untuk lingkungan produksi, cara Anda menyiapkan ADC bergantung pada layanan dan konteks. Untuk informasi selengkapnya, lihat Menyiapkan Kredensial Default Aplikasi.

Untuk lingkungan pengembangan lokal, Anda dapat menyiapkan ADC dengan kredensial yang terkait dengan Akun Google Anda:

1. Install the Google Cloud CLI, then initialize it by running the following command:

   gcloud init

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.

   Layar login akan muncul. Setelah Anda login, kredensial Anda disimpan dalam file kredensial lokal yang digunakan oleh ADC.
