Contoh Kode Python

Contoh kode berikut, yang menggunakan Library Klien Google API untuk Python, tersedia untuk YouTube Reporting API dan YouTube Analytics API. Anda dapat mendownload contoh kode ini dari folder python di repositori contoh kode YouTube API di GitHub.

Laporan massal

Mengambil laporan

Contoh kode ini menunjukkan cara mengambil laporan yang dibuat oleh tugas tertentu. Metode ini memanggil metode jobs.list untuk mengambil tugas pelaporan. Kemudian, metode reports.list akan dipanggil dengan parameter jobId yang ditetapkan ke ID tugas tertentu untuk mengambil laporan yang dibuat oleh tugas tersebut. Terakhir, contoh ini mencetak URL download untuk setiap laporan.

#!/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>

Laporan kueri yang ditargetkan

Mengambil statistik saluran harian

Contoh ini memanggil YouTube Analytics API untuk mengambil jumlah tontonan harian dan metrik lainnya bagi channel pengguna yang memberi otorisasi untuk tahun kalender 2017. Sampel menggunakan library klien Google API Python.

Kode ini meminta izin pengguna untuk mengakses cakupan https://www.googleapis.com/auth/yt-analytics.readonly.

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

Aplikasi Anda mungkin juga perlu meminta akses ke cakupan lain. Misalnya, aplikasi yang memanggil YouTube Analytics API dan YouTube Data API mungkin mengharuskan pengguna untuk memberikan akses ke akun YouTube mereka. Ringkasan otorisasi mengidentifikasi cakupan yang biasanya digunakan dalam aplikasi yang memanggil YouTube Analytics API.

Menyiapkan kredensial otorisasi

Sebelum menjalankan contoh ini secara lokal untuk pertama kalinya, Anda perlu menyiapkan kredensial otorisasi untuk project Anda:

  1. Buat atau pilih project di Konsol API Google.
  2. Aktifkan YouTube Analytics API untuk project Anda.
  3. Di bagian atas halaman Kredensial, pilih tab Layar persetujuan OAuth. Pilih alamat Email, masukkan nama Produk jika belum ditetapkan, lalu klik tombol Simpan.
  4. Di halaman Kredensial, klik tombol Create credentials, lalu pilih Oauth client ID.
  5. Pilih jenis aplikasi Lainnya, masukkan nama "Panduan Memulai YouTube Analytics API", lalu klik tombol Buat.
  6. Klik OK untuk menutup dialog yang dihasilkan.
  7. Klik tombol (Download JSON) di sebelah kanan client ID.
  8. Pindahkan file yang didownload ke direktori kerja.

Menginstal library yang diperlukan

Anda juga harus menginstal Library Klien Google API untuk Python dan beberapa library tambahan:

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

Menjalankan kode

Sekarang, Anda siap untuk benar-benar menguji sampel:

  1. Salin contoh kode di bawah ini ke direktori kerja.
  2. Di contoh, perbarui nilai variabel CLIENT_SECRETS_FILE agar cocok dengan lokasi file yang Anda download setelah menyiapkan kredensial otorisasi.
  3. Jalankan kode contoh di jendela terminal:
    python yt_analytics_v2.py
  4. Ikuti alur otorisasi. Alur autentikasi mungkin dimuat secara otomatis di browser Anda, atau Anda mungkin perlu menyalin URL autentikasi ke jendela browser. Di akhir alur otorisasi, jika perlu, tempel kode otorisasi yang ditampilkan di browser ke jendela terminal Anda, lalu klik [return].
  5. Kueri API dijalankan dan respons JSON merupakan output ke jendela terminal.
