Python Kod Örnekleri

Python için Google API'leri İstemci Kitaplığı'nı kullanan aşağıdaki kod örnekleri, YouTube Reporting API ve YouTube Analytics API için mevcuttur. Bu kod örneklerini GitHub'daki YouTube API'leri kod örneği deposunun python klasöründen indirebilirsiniz.

Toplu raporlar

Raporları alma

Bu kod örneğinde, belirli bir iş tarafından oluşturulan raporların nasıl alınacağı gösterilmektedir. Raporlama işlerini almak için jobs.list yöntemini çağırır. Daha sonra, jobId parametresini belirli bir iş kimliğine ayarlayarak, söz konusu iş tarafından oluşturulan raporları almak için reports.list yöntemini çağırır. Son olarak örnek, her raporun indirme URL'sini yazdırır.

#!/usr/bin/python

###
#
# This script retrieves YouTube Reporting API reports. Use cases:
# 1. If you specify a report URL, the script downloads that report.
# 2. Otherwise, if you specify a job ID, the script retrieves a list of
#    available reports for that job and prompts you to select a report.
#    Then it retrieves that report as in case 1.
# 3. Otherwise, the list retrieves a list of jobs for the user or,
#    if specified, the content owner that the user is acting on behalf of.
#    Then it prompts the user to select a job, and then executes case 2 and
#    then case 1.
# Usage examples:
# python retrieve_reports.py --content_owner_id=<CONTENT_OWNER_ID> --local_file=<LOCAL_FILE>
# python retrieve_reports.py --content_owner_id=<CONTENT_OWNER_ID> --job_id=<JOB_ID> --local_file=<LOCAL_FILE>
# python retrieve_reports.py --content_owner_id=<CONTENT_OWNER_ID> --report_url=<REPORT_URL> --local_file=<LOCAL_FILE>

Hedeflenen sorgu raporları

Günlük kanal istatistiklerini al

Bu örnekte YouTube Analytics API'si, 2017 takvim yılında kullanıcının kanalı için geçerli olan görüntüleme sayısı ve diğer metrikleri alır. Örnekte Google API'leri Python istemci kitaplığı kullanılmaktadır.

Kod, https://www.googleapis.com/auth/yt-analytics.readonly kapsamına erişmek için kullanıcının iznini ister.

SCOPES = ['https://www.googleapis.com/auth/yt-analytics.readonly']

Uygulamanızın diğer kapsamlara da erişim istemesi gerekebilir. Örneğin, YouTube Analytics API ve YouTube Data API'yi çağıran bir uygulamanın, kullanıcıların YouTube hesaplarına da erişim izni vermesi gerekebilir. Yetkilendirmeye genel bakış, genellikle YouTube Analytics API'sini çağıran uygulamalarda kullanılan kapsamları tanımlar.

Yetkilendirme kimlik bilgilerini ayarlayın

Bu örneği ilk kez yerel olarak çalıştırmadan önce projeniz için yetkilendirme kimlik bilgilerini ayarlamanız gerekir:

  1. Google API Konsolu'nda proje oluşturun veya seçin.
  2. Projeniz için YouTube Analytics API'yi etkinleştirin.
  3. Kimlik bilgileri sayfasının üst kısmında OAuth izin ekranı sekmesini seçin. Bir e-posta adresi seçin, ayarlanmamışsa ürün adını girin ve Kaydet düğmesini tıklayın.
  4. Kimlik bilgileri sayfasında Kimlik bilgisi oluştur düğmesini tıklayın ve Oauth istemci kimliği'ni seçin.
  5. Diğer uygulama türünü seçin, "YouTube Analytics API Hızlı Başlangıç" adını girin ve Oluştur düğmesini tıklayın.
  6. Açılan iletişim kutusunu kapatmak için Tamam'ı tıklayın.
  7. İstemci kimliğinin sağındaki (JSON'ı indir) düğmesini tıklayın.
  8. İndirilen dosyayı çalışma dizininize taşıyın.

Gerekli kitaplıkları yükleyin

Ayrıca, Python için Google API'leri İstemci Kitaplığı'nı ve bazı ek kitaplıkları yüklemeniz gerekir:

pip install --upgrade google-api-python-client
pip install --upgrade google-auth google-auth-oauthlib google-auth-httplib2

Kodu çalıştır

Artık örneği test etmeye hazırsınız:

  1. Aşağıdaki kod örneğini çalışma dizininize kopyalayın.
  2. Örnekte, yetkilendirme kimlik bilgilerinizi ayarladıktan sonra indirdiğiniz dosyanın konumuyla eşleşecek şekilde CLIENT_SECRETS_FILE değişkeninin değerini güncelleyin.
  3. Örnek kodu bir terminal penceresinde çalıştırın:
    python yt_analytics_v2.py
  4. Yetkilendirme akışını tamamlayın. Yetkilendirme akışı tarayıcınızda otomatik olarak yüklenebilir veya kimlik doğrulama URL'sini bir tarayıcı penceresine kopyalamanız gerekebilir. Gerekirse yetkilendirme akışının sonunda, tarayıcıda görüntülenen yetkilendirme kodunu terminal pencerenize yapıştırın ve [iade] düğmesini tıklayın.
  5. API sorgusu yürütülür ve JSON yanıtı, terminal penceresine verilir.
