آپلود و ادعای یک ویدیو

برای کسب درآمد از یک ویدیوی YouTube، ابتدا باید آن را با یک دارایی مرتبط کنید. روش create_asset یک دارایی جدید برای ویدیوی تازه آپلود شده ایجاد می کند.

درست مانند آنچه برای ویدیو انجام دادیم، یک منبع JSON جزئی ایجاد می‌کنیم که نوع دارایی برای ایجاد (یک ویدیوی وب) را مشخص می‌کند و عنوان و توضیحاتی را برای دارایی جدید ارائه می‌کند. منبع JSON را به متد assets.insert می‌دهیم که دارایی را ایجاد می‌کند و شناسه منحصربه‌فرد آن را برمی‌گرداند. باز هم، اسکریپت باید آن مقدار را در مراحل بعدی به روش های دیگر منتقل کند.

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(
    
    body=body
  ).execute()

  return assets_insert_response["id"]

قبل از اینکه بتوانید از یک ویدیو کسب درآمد کنید، YouTube باید بداند که مالک دارایی مرتبط چه کسی است. بنابراین، با ایجاد دارایی، اکنون ownership دارایی را پیکربندی می‌کنیم. در نمونه، مشخص می‌کنیم که مالک محتوا مالکیت جهانی این دارایی را دارد.

  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(
    
    assetId=asset_id,
    body=body
  ).execute()

مرحله بعدی این است که ویدیوی آپلود شده را با دارایی مربوطه با ادعای ویدیو مرتبط کنید. این ادعا پیوند بین ویدیو و سیستم مدیریت حقوق YouTube را ارائه می‌کند که مالکیت ویدیو را ایجاد می‌کند و به مالک امکان می‌دهد خط‌مشی کسب درآمد را تنظیم کند.

روش claim_video حقوق سمعی و بصری را ادعا می کند. اگر پارامتر policyId را در خط فرمان قرار دهید، این روش خط مشی مشخص شده را در ویدیو اعمال می کند. اگر پارامتر را وارد نکنید، این روش خط مشی استاندارد "کسب درآمد" را اعمال می کند.

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(
    
    body=body
  ).execute()

ما این ویدیو را ادعا کرده‌ایم و یک خط‌مشی کسب درآمد برای آن اعمال کرده‌ایم. مرحله آخر این است که مشخص کنید چه نوع تبلیغاتی در ویدیو نمایش داده شود. هر زمان که خط‌مشی «کسب درآمد» اعمال شود، YouTube گزینه‌های تبلیغاتی را بررسی می‌کند و پردرآمدترین نوع تبلیغات موجود را نشان می‌دهد.

نمونه به YouTube می‌گوید که تبلیغات TrueView در جریان را با این ویدیو نشان دهد.

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,
    
    body=body
  ).execute()
