Mengupload dan Mengklaim Video

Contoh kode ini menunjukkan cara mengupload video YouTube dan menerapkan kebijakan monetisasi pada video tersebut. Untuk memonetisasi video, Anda harus mengklaim video dengan asset di sistem pengelolaan hak YouTube. Sampel mengupload video, membuat aset baru, mengklaim video menggunakan aset tersebut, dan menerapkan kebijakan monetisasi pada video tersebut.

Contoh ini disajikan sebagai serangkaian langkah yang disertakan bersama dengan bagian kode yang relevan. Anda dapat menemukan seluruh skrip di akhir halaman ini. Kode ini ditulis di Python. Library klien untuk bahasa pemrograman populer lainnya juga tersedia.

Mengurai command line

Metode parse_options menggunakan OptionParser dari library klien Python untuk membuat objek options yang berisi setiap argumen command line sebagai properti. Metode berikutnya akan mengambil nilai dari objek options sesuai kebutuhan.

Contoh argumen command line skrip tercantum di bawah ini. Dua kolom pertama (file dan channelId) wajib ada; sisanya bersifat opsional.

• file: Nama dan lokasi file video yang akan diupload.

  Example: --file="/home/path/to/file.mov"

• channelId: Channel YouTube tempat Anda ingin mengupload video. Channel tersebut harus dikelola oleh akun Pengelola Konten YouTube milik pengguna yang diautentikasi. Anda dapat mengambil ID channel di setelan akun YouTube untuk pengguna terautentikasi atau dengan menggunakan metode channels.list.

  Example: --channelId="UC_x5XG1OV2P6uZZ5FSM9Ttw"

• title: Judul untuk video yang sedang Anda upload. Nilai defaultnya adalah Test title.

  Example: --title="Summer vacation in California"

• description: Deskripsi video yang sedang Anda upload. Nilai defaultnya adalah Test description.

  Example: --description="Had a great time surfing in Santa Cruz"

• category: ID kategori untuk kategori video YouTube yang terkait dengan video. Nilai defaultnya adalah 22, yang mengacu pada kategori People & Blogs.

  Example: --category=22

• keywords: Daftar kata kunci yang dipisahkan koma yang terkait dengan video. Nilai defaultnya adalah string kosong.

  Example: --keywords="surfing, beach volleyball"

• privacyStatus: Status privasi video. Perilaku default adalah video yang diupload dapat dilihat oleh publik (public). Saat mengupload video uji coba, Anda dapat menentukan nilai argumen --privacyStatus untuk memastikan bahwa video tersebut bersifat pribadi atau tidak publik. Nilai yang valid adalah public, private, dan unlisted.

  Example: --privacyStatus="private"

• policyId: Kebijakan monetisasi yang akan diterapkan pada video yang diupload. Kebijakan ini harus dikaitkan dengan akun Pengelola Konten YouTube milik pengguna yang diautentikasi. Kebijakan default-nya adalah kebijakan "monetisasi" YouTube standar.

  Example: --policyId="S309961703555739"

def parse_options():
  parser = OptionParser()
  parser.add_option("--file", dest="file", help="Video file to upload")
  parser.add_option("--title", dest="title", help="Video title",
    default="Test Title")
  parser.add_option("--description", dest="description",
    help="Video description",
    default="Test Description")
  parser.add_option("--category", dest="category",
    help="Numeric video category. " +
      "See https://developers.google.com/youtube/v3/docs/videoCategories/list",
    default="22")
  parser.add_option("--keywords", dest="keywords",
    help="Video keywords, comma separated", default="")
  parser.add_option("--privacyStatus", dest="privacyStatus",
    help="Video privacy status: public, private or unlisted",
    default="public")
  parser.add_option("--policyId", dest="policyId",
    help="Optional id of a saved claim policy")
  parser.add_option("--channelId", dest="channelId",
    help="Id of the channel to upload to. Must be managed by your CMS account")
  (options, args) = parser.parse_args()

  return options

Mengizinkan permintaan

Pada langkah ini, kami akan menerapkan otorisasi OAuth 2.0 ke dalam skrip. Hal ini memungkinkan pengguna yang menjalankan skrip untuk memberikan otorisasi pada skrip agar dapat melakukan permintaan API yang diatribusikan ke akun pengguna.

Membuat file client_secrets.json

Jenis otorisasi yang ditampilkan dalam contoh memerlukan file client_secrets.json, yang berisi informasi dari Konsol API Google, untuk melakukan otorisasi. Anda juga harus mendaftarkan aplikasi Anda. Untuk penjelasan lebih lengkap tentang cara kerja otorisasi, lihat panduan otorisasi. Perlu diperhatikan bahwa contoh ini mengharuskan layanan YouTube Data API V3 dan YouTube Content ID API dikonfigurasi di Konsol API untuk project Anda.

 {
  "web": {
    "client_id": "INSERT CLIENT ID HERE",
    "client_secret": "INSERT CLIENT SECRET HERE",
    "redirect_uris": [],
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token"
  }
}

Kode otorisasi dalam skrip

Skrip ini menyertakan pernyataan import berikut untuk memungkinkan autentikasi dan otorisasi pengguna:

from oauth2client.file import Storage
from oauth2client.client import flow_from_clientsecrets
from oauth2client.tools import run

Selanjutnya, metode get_authenticated_services membuat objek FLOW menggunakan data dari file client_secrets.json yang dikonfigurasi pada langkah sebelumnya. Jika pengguna mengizinkan aplikasi kita untuk mengirimkan permintaan API atas nama pengguna, kredensial yang dihasilkan akan disimpan dalam objek Storage untuk digunakan nanti. Pengguna perlu memberikan otorisasi ulang ke aplikasi kita jika masa berlaku kredensial berakhir.

YOUTUBE_SCOPES = (
  # An OAuth 2 access scope that allows for full read/write access.
  "https://www.googleapis.com/auth/youtube",
  # A scope that grants access to YouTube Partner API functionality.
  "https://www.googleapis.com/auth/youtubepartner")

flow = flow_from_clientsecrets(
  CLIENT_SECRETS_FILE,
  scope=" ".join(YOUTUBE_SCOPES),
  message=MISSING_CLIENT_SECRETS_MESSAGE
)

storage = Storage(CACHED_CREDENTIALS_FILE)
credentials = storage.get()

if credentials is None or credentials.invalid:
  credentials = run(flow, storage)

Mendapatkan layanan

Setelah otorisasi berhasil, kita memperoleh layanan yang diperlukan untuk operasi yang ingin kita lakukan. Sampel tersebut menggunakan YouTube Data API untuk mengupload video dan YouTube Content ID API untuk membuat aset dan mengklaim video. Kami membuat layanan terpisah untuk memberikan akses terotorisasi ke fungsi kedua API.

from googleapiclient.discovery import build
import httplib2

YOUTUBE_API_SERVICE_NAME = "youtube"
YOUTUBE_API_VERSION = "v3"
YOUTUBE_CONTENT_ID_API_SERVICE_NAME = "youtubePartner"
YOUTUBE_CONTENT_ID_API_VERSION = "v1"

youtube = build(YOUTUBE_API_SERVICE_NAME, YOUTUBE_API_VERSION,
  http=credentials.authorize(httplib2.Http()))

youtube_partner = build(YOUTUBE_CONTENT_ID_API_SERVICE_NAME,
  YOUTUBE_CONTENT_ID_API_VERSION, http=credentials.authorize(httplib2.Http()),
  static_discovery=False)

return (youtube, youtube_partner)

Langkah 2: Identifikasi pemilik konten

Untuk membuat aset dan membuat klaim, pengguna yang diautentikasi harus memiliki akun Pengelola Konten YouTube. Akun Pengelola Konten memiliki objek pengelolaan hak untuk satu atau beberapa pemilik konten. Pemilik konten adalah pemegang hak cipta yang memiliki hak untuk memutuskan apakah akan memonetisasi, melacak, atau memblokir video.

Metode get_content_owner mengambil ID pemilik konten di akun Pengelola Konten milik pengguna yang diautentikasi. Sebagian besar akun memiliki satu pemilik konten (pengguna terautentikasi), tetapi jika akun memiliki beberapa pemilik konten, metode akan menampilkan pemilik konten pertama.

def get_content_owner_id(youtube_partner):
  try:
    content_owners_list_response = youtube_partner.contentOwners().list(
      fetchMine=True
    ).execute()
  except HttpError, e:
    if INVALID_CREDENTIALS in e.content:
      logging.error("The request is not authorized by a Google Account that "
        "is linked to a YouTube content owner. Please delete '%s' and "
        "re-authenticate with a YouTube content owner account." %
        CACHED_CREDENTIALS_FILE)
      exit(1)
    else:
      raise

  # This returns the CMS user id of the first entry returned
  # by youtubePartner.contentOwners.list()
  # See https://developers.google.com/youtube/partner/reference/rest/v1/contentOwners/list
  # Normally this is what you want, but if you authorize with a Google Account
  # that has access to multiple YouTube content owner accounts, you need to
  # iterate through the results.
  return content_owners_list_response["items"][0]["id"]

Langkah 4: Buat aset

Untuk memonetisasi video YouTube, Anda harus mengaitkannya terlebih dahulu dengan aset. Metode create_asset akan membuat aset baru untuk video yang baru diupload.

Sama seperti yang dilakukan pada video, kita membuat resource JSON parsial yang mengidentifikasi jenis aset yang akan dibuat (video web) dan memberikan judul serta deskripsi untuk aset baru tersebut. Kita meneruskan resource JSON ke metode assets.insert, yang membuat aset dan menampilkan ID uniknya. Sekali lagi, skrip harus meneruskan nilai tersebut ke metode lain di langkah berikutnya.

def create_asset(youtube_partner, content_owner_id, title, description):
  # This creates a new asset corresponding to a video on the web.
  # The asset is linked to the corresponding YouTube video via a
  # claim that will be created later.
  body = dict(
    type="web",
    metadata=dict(
      title=title,
      description=description
    )
  )

  assets_insert_response = youtube_partner.assets().insert(
    onBehalfOfContentOwner=content_owner_id,
    body=body
  ).execute()

  return assets_insert_response["id"]

Langkah 5: Perbarui kepemilikan

Sebelum dapat memonetisasi video, YouTube harus mengetahui pemilik aset terkait. Jadi, setelah aset dibuat, sekarang kita akan mengonfigurasi ownership aset. Dalam contoh ini, kami menyebutkan bahwa pemilik konten memiliki aset di seluruh dunia.

  def set_asset_ownership(youtube_partner, content_owner_id, asset_id):
  # This specifies that content_owner_id owns 100% of the asset worldwide.
  # Adjust as needed.
  body = dict(
    general=[dict(
      owner=content_owner_id,
      ratio=100,
      type="exclude",
      territories=[]
    )]
  )

  youtube_partner.ownership().update(
    onBehalfOfContentOwner=content_owner_id,
    assetId=asset_id,
    body=body
  ).execute()

Langkah 6: Klaim video

Langkah selanjutnya adalah mengaitkan video yang diupload dengan asetnya yang sesuai dengan mengklaim video tersebut. Klaim tersebut menghubungkan video dengan sistem pengelolaan hak YouTube, yang menetapkan kepemilikan video dan memungkinkan pemiliknya untuk menetapkan kebijakan monetisasi.

Metode claim_video mengklaim hak audiovisual. Jika Anda menyertakan parameter policyId di command line, metode tersebut akan menerapkan kebijakan yang ditentukan pada video; jika Anda tidak menyertakan parameter tersebut, metode tersebut akan menerapkan kebijakan "monetisasi" standar.

def claim_video(youtube_partner, content_owner_id, asset_id, video_id,
  policy_id):
  # policy_id can be set to the id of an existing policy, which can be obtained
  # via youtubePartner.policies.list()
  # See https://developers.google.com/youtube/partner/reference/rest/v1/policies/list
  # If you later update that existing policy, the claim will also be updated.
  if policy_id:
    policy = dict(
      id=policy_id
    )
  # If policy_id is not provided, a new inline policy is created.
  else:
    policy = dict(
      rules=[dict(
        action="monetize"
      )]
    )

  body = dict(
    assetId=asset_id,
    videoId=video_id,
    policy=policy,
    contentType="audiovisual"
  )

  youtube_partner.claims().insert(
    onBehalfOfContentOwner=content_owner_id,
    body=body
  ).execute()

Langkah 7: Tetapkan opsi iklan

Kami telah mengklaim video tersebut dan menerapkan kebijakan monetisasi pada video tersebut. Langkah terakhir adalah menentukan jenis iklan yang akan ditampilkan dalam video. Setiap kali kebijakan "monetisasi" berlaku, YouTube akan memeriksa opsi iklan dan menampilkan jenis iklan dengan pendapatan tertinggi yang tersedia.

Contoh ini memberi tahu YouTube untuk menampilkan iklan TrueView in-stream dengan video ini.

def set_advertising_options(youtube_partner, content_owner_id, video_id):
  # This enables the TrueView ad format for the given video.
  # Adjust as needed.
  body = dict(
    adFormats=["trueview_instream"]
  )

  youtube_partner.videoAdvertisingOptions().update(
    videoId=video_id,
    onBehalfOfContentOwner=content_owner_id,
    body=body
  ).execute()
