如何在 Python 脚本中使用 Google OAuth2

在使用 Python 脚本将视频上传到 YouTube 频道时，若希望将视频上传到第二个频道，需要解决 OAuth2 授权的问题。

解决方案：

1. 创建新的 Google Cloud 项目：

from google.oauth2 import service_account
import googleapiclient.discovery

def create_new_project():
  credentials = service_account.Credentials.from_service_account_file(
  http://www.jshk.com.cn/mb/reg.asp?kefu=xiaoding；//爬虫IP免费获取；
    'service_account.json')

  service = googleapiclient.discovery.build(
    'cloudresourcemanager', 'v1', credentials=credentials)

  body = {
    'projectId': 'your-new-project-id'
  }

  new_project = service.projects().create(body=body).execute()

  print('New project created: {}'.format(new_project['projectId']))

create_new_project()

2. 为新项目启用 YouTube Data API：

from google.oauth2 import service_account
import googleapiclient.discovery

def enable_youtube_api():
  credentials = service_account.Credentials.from_service_account_file(
    'service_account.json')

  service = googleapiclient.discovery.build(
    'cloudresourcemanager', 'v1', credentials=credentials)

  project_id = 'your-new-project-id'

  body = {
    'serviceIds': ['youtube.googleapis.com']
  }

  service.projects().enableServices(projectId=project_id, body=body).execute()

  print('YouTube Data API enabled for project: {}'.format(project_id))

enable_youtube_api()

3. 为新项目创建 OAuth2 凭据：

from google.oauth2 import service_account
import googleapiclient.discovery

def create_oauth2_credentials():
  credentials = service_account.Credentials.from_service_account_file(
    'service_account.json')

  service = googleapiclient.discovery.build(
    'iam', 'v1', credentials=credentials)

  project_id = 'your-new-project-id'

  body = {
    'serviceAccount': 'service-account-name@your-new-project-id.iam.gserviceaccount.com'
  }

  credentials = service.projects().serviceAccounts().keys().create(
    name='projects/-/serviceAccounts/' + body['serviceAccount'],
    body=body).execute()

  print('OAuth2 credentials created for service account: {}'.format(credentials['name']))

create_oauth2_credentials()

4. 使用新项目和创建的 OAuth2 凭据上传视频：

from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

def upload_video():
  # OAuth2 flow for the new project
  flow = InstalledAppFlow.from_client_secrets_file('client_secrets.json', ['https://www.googleapis.com/auth/youtube.upload'])
  credentials = flow.run_console()

  youtube = build('youtube', 'v3', credentials=credentials)

  # Upload the video
  video_metadata = {
      'snippet': {
          'title': 'My Video',
          'description': 'This is a test video',
          'tags': ['test', 'video']
      },
      'status': {
          'privacyStatus': 'private'
      }
  }

  video_data = open('video.mp4', 'rb').read()

  response = youtube.videos().insert(
      part='snippet,status',
      body=video_metadata,
      media_body=video_data).execute()

  print('Video uploaded: {}'.format(response['id']))

upload_video()
