Mengupload objek dari sistem file

Halaman ini menunjukkan cara mengupload objek ke bucket Cloud Storage dari sistem file lokal Anda. Objek yang diupload terdiri dari data yang ingin Anda simpan bersama dengan metadata terkait. Untuk ringkasan konseptual, termasuk cara memilih metode upload yang optimal berdasarkan ukuran file Anda, lihat Upload dan download.

Untuk mengetahui petunjuk tentang cara mengupload dari memori, lihat Mengupload objek dari memori.

Peran yang diperlukan

Untuk mendapatkan izin yang diperlukan untuk mengupload objek ke bucket, minta administrator untuk memberi Anda peran IAM Storage Object User (roles/storage.objectUser) di bucket. Peran bawaan ini berisi izin yang diperlukan untuk mengupload objek ke bucket. Untuk melihat izin yang benar-benar diperlukan, luaskan bagian Izin yang diperlukan:

Izin yang diperlukan

  • storage.objects.create
  • storage.objects.delete
    • Izin ini hanya diperlukan untuk upload yang menimpa objek yang ada.
  • storage.objects.get
    • Izin ini hanya diperlukan jika Anda berencana menggunakan Google Cloud CLI untuk melakukan tugas di halaman ini.
  • storage.objects.list
    • Izin ini hanya diperlukan jika Anda berencana menggunakan Google Cloud CLI untuk melakukan tugas di halaman ini. Izin ini juga diperlukan jika Anda ingin menggunakan Konsol Google Cloud untuk memverifikasi objek yang telah diupload.

Jika Anda berencana menggunakan konsol Google Cloud untuk melakukan tugas di halaman ini, Anda juga memerlukan izin storage.buckets.list, yang tidak disertakan dalam peran Storage Object User (roles/storage.objectUser). Untuk mendapatkan izin ini, minta administrator untuk memberi Anda peran Storage Admin (roles/storage.admin) di project tersebut.

Anda juga bisa mendapatkan izin ini dengan peran standar atau peran khusus lainnya.

Untuk informasi tentang cara memberikan peran pada bucket, lihat Menggunakan IAM dengan bucket.

Mengupload bbjek ke bucket

Selesaikan langkah-langkah berikut untuk mengupload objek ke bucket:

Konsol

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

    Buka Bucket

  2. Dalam daftar bucket, klik nama bucket tempat Anda ingin mengupload objek.

  3. Di tab Objek untuk bucket:

    • Tarik file dari desktop atau pengelola file ke panel utama di Konsol Google Cloud.

    • Atau klik tombol Upload File, pilih file yang ingin diupload dalam dialog yang muncul, lalu klik Buka.

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 cp:

gcloud storage cp OBJECT_LOCATION gs://DESTINATION_BUCKET_NAME

Dengan keterangan:

  • OBJECT_LOCATION adalah jalur lokal ke objek Anda. Contohnya, Desktop/dog.png

  • DESTINATION_BUCKET_NAME adalah nama bucket tempat Anda mengupload objek. Contohnya, my-bucket.

Jika berhasil, responsnya akan terlihat seperti contoh berikut:

Completed files 1/1 | 164.3kiB/164.3kiB

Anda dapat menetapkan metadata objek kunci tetap dan kustom sebagai bagian dari upload objek menggunakan flag perintah.

# Create a text object in Cloud Storage
resource "google_storage_bucket_object" "default" {

REST API

JSON API

JSON API membedakan antara upload media, yang hanya menyertakan data objek dalam permintaan, dan upload multibagian JSON API, yang mana kedua data objek tersebut dan metadata objek disertakan dalam permintaan.

Upload media (upload permintaan tunggal tanpa metadata objek)

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

  2. Gunakan cURL untuk memanggil JSON API dengan permintaan Objek POST:

    curl -X POST --data-binary @OBJECT_LOCATION \
        -H "Authorization: Bearer $(gcloud auth print-access-token)" \
        -H "Content-Type: OBJECT_CONTENT_TYPE" \
        "https://storage.googleapis.com/upload/storage/v1/b/BUCKET_NAME/o?uploadType=media&name=OBJECT_NAME"

    Dengan keterangan:

    • OBJECT_LOCATION adalah jalur lokal ke objek Anda. Contoh, Desktop/dog.png.
    • OBJECT_CONTENT_TYPE adalah jenis konten objek. Contohnya, image/png
    • BUCKET_NAME adalah nama bucket tempat Anda mengupload objek. Contohnya, my-bucket
    • OBJECT_NAME adalah nama yang dienkode ke URL yang ingin Anda berikan untuk objek. Misalnya, pets/dog.png, dienkode URL sebagai pets%2Fdog.png.

Upload multibagian JSON API (upload permintaan tunggal yang menyertakan metadata objek)

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

  2. Buat file multipart/related yang berisi informasi berikut:

    --BOUNDARY_STRING
    Content-Type: application/json; charset=UTF-8
    
    OBJECT_METADATA
    
    --BOUNDARY_STRING
    Content-Type: OBJECT_CONTENT_TYPE
    
    OBJECT_DATA
    --BOUNDARY_STRING--

    Dengan keterangan:

    • BOUNDARY_STRING adalah string yang Anda tentukan yang mengidentifikasi berbagai bagian dari file multibagian. Contoh, separator_string.
    • OBJECT_METADATA adalah metadata yang ingin Anda sertakan untuk file, dalam format JSON. Setidaknya, bagian ini harus menyertakan atribut name untuk objek, misalnya {"name": "myObject"}.
    • OBJECT_CONTENT_TYPE adalah jenis konten objek. Misalnya, text/plain.
    • OBJECT_DATA adalah data untuk objek.

    Contoh:

    --separator_string
    Content-Type: application/json; charset=UTF-8
    
    {"name":"my-document.txt"}
    
    --separator_string
    Content-Type: text/plain
    
    This is a text file.
    --separator_string--
  3. Gunakan cURL untuk memanggil JSON API dengan permintaan Objek POST:

    curl -X POST --data-binary @MULTIPART_FILE_LOCATION \
        -H "Authorization: Bearer $(gcloud auth print-access-token)" \
        -H "Content-Type: multipart/related; boundary=BOUNDARY_STRING" \
        -H "Content-Length: MULTIPART_FILE_SIZE" \
        "https://storage.googleapis.com/upload/storage/v1/b/BUCKET_NAME/o?uploadType=multipart"

    Dengan keterangan:

    • MULTIPART_FILE_LOCATION adalah jalur lokal ke file multibagian yang Anda buat di langkah 2. Contoh, Desktop/my-upload.multipart.
    • BOUNDARY_STRING adalah string batas yang Anda tentukan di Langkah 2. Contoh, my-boundary.
    • MULTIPART_FILE_SIZE adalah ukuran total, dalam byte, dari file multibagian yang Anda buat di Langkah 2. Contoh, 2000000.
    • BUCKET_NAME adalah nama bucket tempat Anda mengupload objek. Contohnya, my-bucket

Jika permintaan berhasil, server akan menampilkan kode status HTTP 200 OK beserta metadata file.

XML API

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

  2. Gunakan cURL untuk memanggil XML API dengan permintaan Objek PUT:

    curl -X PUT --data-binary @OBJECT_LOCATION \
        -H "Authorization: Bearer $(gcloud auth print-access-token)" \
        -H "Content-Type: OBJECT_CONTENT_TYPE" \
        "https://storage.googleapis.com/BUCKET_NAME/OBJECT_NAME"

    Dengan keterangan:

    • OBJECT_LOCATION adalah jalur lokal ke objek Anda. Contoh, Desktop/dog.png.
    • OBJECT_CONTENT_TYPE adalah jenis konten objek. Contohnya, image/png
    • BUCKET_NAME adalah nama bucket tempat Anda mengupload objek. Contohnya, my-bucket
    • OBJECT_NAME adalah nama yang dienkode ke URL yang ingin Anda berikan untuk objek. Contohnya, pets/dog.png, yang berenkode URL menjadi pets%2Fdog.png.

Anda dapat menetapkan metadata objek tambahan sebagai bagian dari upload objek pada header permintaan dengan cara yang sama seperti contoh sebelumnya menetapkan Content-Type. Jika menggunakan XML API, metadata hanya dapat ditetapkan pada saat objek ditulis, misalnya saat mengupload, menyalin, atau mengganti objek. Untuk informasi selengkapnya, lihat Mengedit metadata objek.
