Library klien Storage Transfer Service

Halaman ini menunjukkan cara memulai Library Klien Cloud untuk Google Storage Transfer API. Baca selengkapnya tentang library klien untuk Cloud API, termasuk Library Klien Google API yang lebih lama, di Penjelasan Library Klien.

Untuk informasi tentang cara mengupdate dari Library Klien Google API ke Library Klien Cloud yang dijelaskan di halaman ini, lihat Panduan Migrasi Storage Transfer Service.

Menginstal library klien

C++

Untuk informasi selengkapnya tentang cara menginstal library C++, lihat panduan Menyiapkan lingkungan pengembangan C++.

C#

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan C#.

Jika Anda menggunakan Visual Studio 2017 atau yang lebih baru, buka jendela pengelola paket nuget dan ketik kode berikut:

Install-Package Google.Cloud.StorageTransfer.V1

Jika Anda menggunakan alat antarmuka command line .NET Core untuk menginstal dependensi, jalankan perintah berikut:

dotnet add package Google.Cloud.StorageTransfer.V1

Go

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Go.

go get cloud.google.com/go/storagetransfer

Java

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Java.

Jika Anda menggunakan Maven, tambahkan kode berikut ke file pom.xml Anda:

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-storage-transfer</artifactId>
    <version>0.2.3</version>
</dependency>

Jika Anda menggunakan Gradle tanpa BOM, tambahkan kode ini ke dependensi Anda:

implementation 'com.google.cloud:google-cloud-storage-transfer:0.2.3'

Node.js

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

npm install --save @google-cloud/storage-transfer

PHP

Untuk informasi selengkapnya, lihat Menggunakan PHP di Google Cloud.

composer require google/cloud

Python

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Python.

pip install --upgrade google-cloud-storage-transfer

Ruby

Untuk informasi selengkapnya, lihat Menyiapkan Lingkungan Pengembangan Ruby.

gem install google-cloud-storage_transfer

Menyiapkan autentikasi

Saat menggunakan library klien, Anda menggunakan Kredensial Default Aplikasi untuk melakukan autentikasi. Untuk informasi selengkapnya, lihat Mengautentikasi menggunakan library klien.

Menggunakan library klien

Contoh berikut menunjukkan cara menggunakan library klien.

Sebelum menggunakan contoh ini, ikuti petunjuk di bagian Mengonfigurasi akses untuk menyiapkan izin yang diperlukan.

C++

Untuk mempelajari cara menginstal dan menggunakan library klien untuk Storage Transfer Service, lihat library klien Storage Transfer Service.

Untuk melakukan autentikasi ke Storage Transfer Service, siapkan Kredensial Default Aplikasi. Untuk mengetahui informasi selengkapnya, lihat Menyiapkan autentikasi untuk lingkungan pengembangan lokal.
