以檔案附件的形式上傳媒體

Python

• Python 3.6 或更高版本
• pip 套件管理工具

• 最新的 Python 專用 Google 用戶端程式庫。如要安裝或更新，請在指令列介面中執行下列指令：

  pip3 install --upgrade google-api-python-client google-auth-oauthlib
  

• 已啟用並設定 Google Chat API 的 Google Cloud 專案。相關步驟請參閱「建構 Google Chat 應用程式」。

• 已設定 Chat 應用程式的授權。如要以檔案附件形式上傳媒體，您必須使用 chat.messages.create 或 chat.messages 授權範圍的使用者驗證功能。

Python

1. 在工作目錄中，建立名為 chat_media_and_attachment_upload.py 的檔案。

2. 在 chat_media_and_attachment_upload.py 中加入下列程式碼：

   from google_auth_oauthlib.flow import InstalledAppFlow
   from googleapiclient.discovery import build
   from googleapiclient.http import MediaFileUpload
   
   # Define your app's authorization scopes.
   # When modifying these scopes, delete the file token.json, if it exists.
   SCOPES = ["https://www.googleapis.com/auth/chat.messages.create"]
   
   def main():
       '''
       Authenticates with Chat API via user credentials,
       then uploads a file as media, creates a message, and
       attaches the file to the message.
       '''
   
       # Authenticate with Google Workspace
       # and get user authorization.
       flow = InstalledAppFlow.from_client_secrets_file(
                     'client_secrets.json', SCOPES)
       creds = flow.run_local_server()
   
       # Build a service endpoint for Chat API.
       service = build('chat', 'v1', credentials=creds)
   
       # Upload a file to Google Chat.
       media = MediaFileUpload('test_image.png', mimetype='image/png')
   
       # Create a message and attach the uploaded file to it.
       attachment_uploaded = service.media().upload(
   
           # The space to upload the attachment in.
           #
           # Replace SPACE with a space name.
           # Obtain the space name from the spaces resource of Chat API,
           # or from a space's URL.
           parent='spaces/SPACE',
   
           # The filename of the attachment, including the file extension.
           body={'filename': 'test_image.png'},
   
           # Media resource of the attachment.
           media_body=media
   
       ).execute()
   
       print(attachment_uploaded)
   
       # Create a Chat message with attachment.
       result = service.spaces().messages().create(
   
           # The space to create the message in.
           #
           # Replace SPACE with a space name.
           # Obtain the space name from the spaces resource of Chat API,
           # or from a space's URL.
           #
           # Must match the space name that the attachment is uploaded to.
           parent='spaces/SPACE',
   
           # The message to create.
           body={
               'text': 'Hello, world!',
               'attachment': [attachment_uploaded]
           }
   
       ).execute()
   
       print(result)
   
   if __name__ == '__main__':
       main()
   

3. 將程式碼中的 SPACE 替換為聊天室名稱即可上傳附件，您可以透過 Chat API 的 spaces.list 方法或聊天室網址取得。

4. 在工作目錄中，建構並執行範例：

   python3 chat_media_and_attachment_upload.py
