ApsaraVideo Live:Gunakan server SDK untuk Python

Prosedur

1. Instal SDK.

   1. Instal Alibaba Cloud Core SDK.

      sudo pip install aliyun-python-sdk-core

   2. Instal ApsaraVideo Live SDK.

      sudo pip install aliyun-python-sdk-live

2. Perbarui SDK.

   1. Perbarui Alibaba Cloud Core SDK.

      sudo pip install aliyun-python-sdk-core --upgrade

   2. Perbarui ApsaraVideo Live SDK.

      sudo pip install aliyun-python-sdk-live --upgrade

3. Gunakan server SDK untuk Python.

   1. Baca deskripsi file. Dalam contoh ini, file DescribeCastersRequest.py dalam SDK digunakan.

      Kelas DescribeCastersRequest dalam file tersebut memiliki beberapa pasang metode get_X dan set_X yang masing-masing digunakan untuk mendapatkan dan menentukan parameter permintaan API.

   2. Buat file konfigurasi bernama config.ini dan letakkan di direktori conf. Sertakan ID AccessKey dan Rahasia AccessKey Anda dalam file konfigurasi tersebut. Contoh:

      [default]
      access_key_id = YOUR_ACCESS_KEY_ID
      access_key_secret = YOUR_ACCESS_KEY_SECRET

      Ganti YOUR_ACCESS_KEY_ID dan YOUR_ACCESS_KEY_SECRET dengan ID AccessKey dan Rahasia AccessKey Anda yang sebenarnya.

      Kemudian, Anda dapat menggunakan kode Python berikut untuk membaca file konfigurasi dan memanggil SDK.

      Kode contoh berikut menggunakan operasi DescribeCasters pada v20161101 SDK sebagai contoh:

      #!/usr/bin/env python
      #coding=utf-8
      
      from configparser import ConfigParser
      from aliyunsdkcore.client import AcsClient
      from aliyunsdkcore.acs_exception.exceptions import ClientException
      from aliyunsdkcore.acs_exception.exceptions import ServerException
      from aliyunsdkcore.auth.credentials import AccessKeyCredential
      from aliyunsdkcore.auth.credentials import StsTokenCredential
      from aliyunsdklive.request.v20161101.DescribeCastersRequest import DescribeCastersRequest
      
      config = ConfigParser()
      config.read('conf/config.ini')
      
      # Pasangan AccessKey dari Akun Alibaba Cloud memiliki izin akses ke semua operasi API. Kami menyarankan Anda menggunakan pasangan AccessKey dari RAM user untuk memanggil operasi API atau melakukan O&M rutin.
      # Kami menyarankan agar Anda tidak menyimpan pasangan AccessKey (ID AccessKey dan Rahasia AccessKey) dalam kode proyek Anda. Jika tidak, pasangan AccessKey tersebut berisiko bocor dan keamanan seluruh sumber daya dalam akun Anda dapat terganggu.
      # Dalam contoh ini, pasangan AccessKey diperoleh dari file konfigurasi untuk mengautentikasi akses API.
      access_key_id = config.get('default', 'access_key_id')
      access_key_secret = config.get('default', 'access_key_secret')
      # Inisialisasi client.
      # Gunakan ID AccessKey dan Rahasia AccessKey dari Akun Alibaba Cloud Anda. Anda dapat memperolehnya di Konsol Manajemen Alibaba Cloud.
      # Dalam contoh ini, wilayah diatur ke cn-hangzhou.
      credentials = AccessKeyCredential(access_key_id, access_key_secret)
      # gunakan STS Token
      # credentials = StsTokenCredential('<your-access-key-id>', '<your-access-key-secret>', '<your-sts-token>')
      client = AcsClient(region_id='cn-hangzhou', credential=credentials)
      # Buat permintaan API.
      request = DescribeCastersRequest()
      request.set_accept_format('json')
      
      request.set_CasterId("testCase")
      request.set_CasterName("testName")
      request.set_StartTime("2020-01-01T12:00:01Z")
      # Kirim permintaan.
      response = client.do_action_with_exception(request)
      # python2:  print(response)
      # Dapatkan hasilnya.
      print(str(response, encoding='utf-8'))
