Menggunakan penangguhan objek

Overview

Halaman ini menjelaskan cara menggunakan penangguhan objek, termasuk menempatkan penangguhan secara default pada objek baru dan menempatkan penangguhan pada setiap objek.

Izin yang diperlukan

Sebelum menggunakan fitur ini di Cloud Storage, Anda harus memiliki izin yang memadai untuk melihat serta memperbarui bucket dan objek di Cloud Storage:

  • Jika Anda adalah pemilik project yang berisi bucket, kemungkinan besar Anda memiliki izin yang diperlukan.

  • Jika menggunakan IAM, Anda harus memiliki izin storage.buckets.update, storage.buckets.get, storage.objects.update, dan storage.objects.get di bucket yang relevan. Lihat Menggunakan Izin IAM untuk mengetahui petunjuk cara mendapatkan peran, seperti Admin Penyimpanan, yang memiliki izin ini.

  • Jika menggunakan ACL, Anda harus memiliki izin PEMILIK pada bucket yang relevan dan pada objek di dalamnya. Lihat Menetapkan ACL untuk mendapatkan petunjuk tentang cara melakukannya.

Menggunakan properti penangguhan berbasis peristiwa default

Tugas berikut menunjukkan cara menetapkan dan melihat properti penangguhan berbasis peristiwa default di bucket. Jika properti ini diaktifkan, objek baru yang ditambahkan ke bucket akan otomatis mendapatkan penangguhan berbasis peristiwa yang ditempatkan di dalamnya.

Menetapkan properti penangguhan berbasis peristiwa default

Guna mengaktifkan atau menonaktifkan properti penangguhan berbasis peristiwa default untuk bucket:

Konsol

  1. Di Konsol Google Cloud, buka halaman Bucket Cloud Storage.

    Buka Bucket

  2. Dalam daftar bucket, klik nama bucket tempat Anda ingin menetapkan properti penangguhan berbasis peristiwa default.

  3. Pilih tab Protection di dekat bagian atas halaman.

    Status saat ini untuk bucket akan muncul di bagian Opsi penangguhan berbasis peristiwa default.

  4. Di bagian Opsi penangguhan berbasis peristiwa default, klik status saat ini untuk mengubahnya.

    Status akan muncul sebagai Aktif atau Nonaktif.

Untuk mempelajari cara mendapatkan informasi error mendetail tentang operasi Cloud Storage yang gagal di Konsol Google Cloud, lihat Pemecahan masalah.

Command line

Gunakan perintah gcloud storage buckets update dengan flag yang sesuai:

gcloud storage buckets update gs://BUCKET_NAME FLAG

Dengan keterangan:

  • BUCKET_NAME adalah nama bucket yang relevan. Contoh, my-bucket.

  • FLAG atau --default-event-based-hold untuk mengaktifkan penangguhan objek berbasis peristiwa default atau --no-default-event-based-hold untuk menonaktifkannya.

REST API

JSON API

  1. Menginstal dan melakukan inisialisasi gcloud CLI , yang memungkinkan Anda membuat token akses untuk header Authorization.

  2. Buat file JSON yang berisi informasi berikut:

    {
  "defaultEventBasedHold": STATE
}

    Dengan STATE adalah true atau false.

  3. Gunakan cURL untuk memanggil JSON API dengan permintaan Bucket PATCH:

    curl -X PATCH --data-binary @JSON_FILE_NAME \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json" \
"https://storage.googleapis.com/storage/v1/b/BUCKET_NAME?fields=defaultEventBasedHold"

    Dengan keterangan:

    • JSON_FILE_NAME adalah jalur untuk file yang Anda buat di Langkah 2.
    • BUCKET_NAME adalah nama bucket yang relevan. Contoh, my-bucket.

XML API

XML API tidak dapat digunakan untuk bekerja dengan penangguhan objek. Sebagai gantinya, gunakan salah satu alat Cloud Storage lain, seperti gcloud CLI.

Mendapatkan status penangguhan default bucket

Untuk melihat apakah bucket menempatkan penangguhan berbasis peristiwa pada objek baru secara default:

Konsol

  1. Di Konsol Google Cloud, buka halaman Bucket Cloud Storage.

    Buka Bucket

  2. Dalam daftar bucket, klik nama bucket yang ingin Anda periksa status berbasis peristiwa defaultnya.

  3. Pilih tab Protection di dekat bagian atas halaman.

  4. Status ini muncul di bagian Opsi penangguhan berbasis peristiwa default.

Untuk mempelajari cara mendapatkan informasi error mendetail tentang operasi Cloud Storage yang gagal di Konsol Google Cloud, lihat Pemecahan masalah.

Command line

Gunakan perintah gcloud storage buckets describe dengan flag --format:

gcloud storage buckets describe gs://BUCKET_NAME --format="default(default_event_based_hold)"

Dengan BUCKET_NAME yang merupakan nama bucket yang statusnya ingin Anda lihat. Contoh, my-bucket.

Jika berhasil, responsnya akan terlihat mirip dengan contoh berikut ini:

default_event_based_hold: true

REST API

JSON API

  1. Menginstal dan melakukan inisialisasi gcloud CLI , yang memungkinkan Anda membuat token akses untuk header Authorization.

  2. Buat file JSON yang berisi informasi berikut:

    {
  "HOLD_TYPE": STATE
}

    Dengan keterangan:

  3. Gunakan cURL untuk memanggil JSON API dengan permintaan PATCH Object:

    curl -X PATCH --data-binary @JSON_FILE_NAME \
-H "Authorization: Bearer $(gcloud auth print-access-token)" \
-H "Content-Type: application/json" \
"https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/o/OBJECT_NAME"

    Dengan keterangan:

    • JSON_FILE_NAME adalah jalur untuk file yang Anda buat di Langkah 2.
    • BUCKET_NAME adalah nama bucket yang relevan. Contoh, my-bucket.
    • OBJECT_NAME adalah nama objek yang dienkode ke URL yang relevan. Misalnya, pets/dog.png, dienkode ke URL sebagai pets%2Fdog.png.

XML API

XML API tidak dapat digunakan untuk bekerja dengan penangguhan objek. Sebagai gantinya, gunakan salah satu alat Cloud Storage lain, seperti gcloud CLI.

Mendapatkan status penangguhan suatu objek

Guna melihat, jika ada, penangguhan pada objek, ikuti petunjuk umum untuk melihat metadata objek.
