이 가이드에서는 Google Chat API의 Media 리소스에서 upload 메서드를 사용하여 Google Chat에 미디어 (파일)를 업로드한 다음 메시지에 첨부하는 방법을 설명합니다.
사용자가 앱에 메시지를 보내면 Google Chat에서 MESSAGE 상호작용 이벤트를 디스패치합니다.
앱에서 수신한 상호작용 이벤트에는 첨부파일을 비롯한 상호작용 이벤트를 나타내는 JSON 페이로드인 요청 본문이 포함됩니다. 첨부파일의 데이터는 첨부파일이 업로드된 콘텐츠 (로컬 파일)인지 아니면 Drive에 저장된 파일인지에 따라 다릅니다. Media 리소스는 이미지, 동영상, 문서와 같이 Google Chat에 업로드된 파일을 나타냅니다.
Attachment 리소스는 메시지에 첨부된 미디어(파일) 인스턴스를 나타냅니다. Attachment 리소스에는 첨부파일이 저장된 위치와 같은 첨부파일에 관한 메타데이터가 포함됩니다.
Media 리소스에서 upload 메서드를 호출한 응답으로 attachment을 설정합니다. attachment 필드는 목록을 허용합니다.
다음 예에서는 PNG 이미지 파일을 업로드하고 메시지에 첨부합니다.
Python
작업 디렉터리에 chat_media_and_attachment_upload.py이라는 파일을 만듭니다.
chat_media_and_attachment_upload.py에 다음 코드를 포함합니다.

코드에서 SPACE을 첨부파일을 업로드할 스페이스 이름으로 바꿉니다. 스페이스 이름은 Chat API의 spaces.list 메서드 또는 스페이스의 URL에서 가져올 수 있습니다.
작업 디렉터리에서 샘플을 빌드하고 실행합니다.
python3chat_media_and_attachment_upload.py
Chat API는 업로드된 파일에 관한 세부정보가 포함된 attachmentDataRef이 포함된 응답 본문을 반환합니다.

The\ndata in the attachment is different depending on whether the attachment is\nuploaded content (a local file) or is a file stored on Drive. The\n[`Media` resource](/workspace/chat/api/reference/rest/v1/media)\nrepresents a file uploaded to Google Chat, like images, videos, and documents.\nThe\n[`Attachment` resource](/workspace/chat/api/reference/rest/v1/spaces.messages.attachments)\nrepresents an instance of media---a file---attached to a message. The `Attachment`\nresource includes the metadata about the attachment, such as\nwhere it's saved.\n\nPrerequisites\n-------------\n\n\n### Python\n\n- A Business or Enterprise [Google Workspace](https://support.google.com/a/answer/6043576) account with access to [Google Chat](https://workspace.google.com/products/chat/).\n\n\u003c!-- --\u003e\n\n- Set up your environment:\n - [Create a Google Cloud project](/workspace/guides/create-project).\n - [Configure the OAuth consent screen](/workspace/guides/configure-oauth-consent).\n - [Enable and configure the Google Chat API](/workspace/chat/configure-chat-api) with a name, icon, and description for your Chat app.\n - Install the Python [Google API Client Library](/workspace/chat/libraries?tab=python#google-api-client-libraries).\n - [Create OAuth client ID credentials](/workspace/chat/authenticate-authorize-chat-user#step-2:) for a desktop application. To run the sample in this guide, save the credentials as a JSON file named `credentials.json` to your local directory.\n- [Choose an authorization scope](/workspace/chat/authenticate-authorize#asynchronous-chat-calls) that supports user authentication.\n\nUpload as a file attachment\n---------------------------\n\nTo upload media and attach it to a message, pass the following in your\nrequest::\n\n- Specify the `chat.messages.create` or `chat.messages` authorization scope.\n- Call the following Google Chat methods:\n 1. To upload the file, call the [`upload` method](/workspace/chat/api/reference/rest/v1/media/upload) on the [`Media`](/workspace/chat/api/reference/rest/v1/media) resource.\n - Set `parent` to the space name of the space that hosts the file.\n - In `body` (the request body), set `filename` to the name of the uploaded file attachment.\n - Set `media_body` as an instance of the file to be uploaded.\n 2. To create a message with the uploaded file attached, call the [`create` method](/workspace/chat/api/reference/rest/v1/spaces.messages/create) on the [`Messages` resource](/workspace/chat/api/reference/rest/v1/spaces.messages).\n - Set `attachment` as the response from calling the [`upload` method](/workspace/chat/api/reference/rest/v1/media/upload) on the [`Media` resource](/workspace/chat/api/reference/rest/v1/media). The `attachment` field accepts a list.\n\nThe following example uploads a PNG image file and attaches it to a message. \n\n### Python\n\n1. In your working directory, create a file named `chat_media_and_attachment_upload.py`.\n2. Include the following code in `chat_media_and_attachment_upload.py`:\n\n from google_auth_oauthlib.flow import InstalledAppFlow\n from googleapiclient.discovery import build\n from googleapiclient.http import MediaFileUpload\n\n # Define your app's authorization scopes.\n # When modifying these scopes, delete the file token.json, if it exists.\n SCOPES = [\"https://www.googleapis.com/auth/chat.messages.create\"]\n\n def main():\n '''\n Authenticates with Chat API via user credentials,\n then uploads a file as media, creates a message, and\n attaches the file to the message.\n '''\n\n # Authenticate with Google Workspace\n # and get user authorization.\n flow = InstalledAppFlow.from_client_secrets_file(\n 'credentials.json', SCOPES)\n creds = flow.run_local_server()\n\n # Build a service endpoint for Chat API.\n service = build('chat', 'v1', credentials=creds)\n\n # Upload a file to Google Chat.\n media = MediaFileUpload('test_image.png', mimetype='image/png')\n\n # Create a message and attach the uploaded file to it.\n attachment_uploaded = service.media().upload(\n\n # The space to upload the attachment in.\n #\n # Replace SPACE with a space name.\n # Obtain the space name from the spaces resource of Chat API,\n # or from a space's URL.\n parent='spaces/\u003cvar translate=\"no\"\u003eSPACE\u003c/var\u003e',\n\n # The filename of the attachment, including the file extension.\n body={'filename': 'test_image.png'},\n\n # Media resource of the attachment.\n media_body=media\n\n ).execute()\n\n print(attachment_uploaded)\n\n # Create a Chat message with attachment.\n result = service.spaces().messages().create(\n\n # The space to create the message in.\n #\n # Replace SPACE with a space name.\n # Obtain the space name from the spaces resource of Chat API,\n # or from a space's URL.\n #\n # Must match the space name that the attachment is uploaded to.\n parent='spaces/\u003cvar translate=\"no\"\u003eSPACE\u003c/var\u003e',\n\n # The message to create.\n body={\n 'text': 'Hello, world!',\n 'attachment': [attachment_uploaded]\n }\n\n ).execute()\n\n print(result)\n\n if __name__ == '__main__':\n main()\n\n3. In the code, replace \u003cvar translate=\"no\"\u003eSPACE\u003c/var\u003e with the space name to\n upload the attachment in, which you can obtain from the\n [`spaces.list` method](/workspace/chat/api/reference/rest/v1/spaces/list)\n in the Chat API, or from a space's URL.\n\n4. In your working directory, build and run the sample:\n\n python3 chat_media_and_attachment_upload.py\n\nThe Chat API returns a response body containing\n`attachmentDataRef` with details about the uploaded file.\n\nLimits and considerations\n-------------------------\n\nAs you prepare to upload files and attach them to messages, take note of these\nlimits and considerations:\n\n- You can upload file sizes up to 200 MB.\n- Some file types aren't supported, and can't be uploaded. For details, see [File types blocked in Google Chat](https://support.google.com/chat/answer/7651457?&co=GENIE.Platform%3DDesktop#File%20types%20blocked%20in%20Google%20Chat).\n- Your message must omit [accessory widgets](/workspace/chat/api/reference/rest/v1/spaces.messages#Message.FIELDS.accessory_widgets).\n\nRelated topics\n--------------\n\n- [Download media as a file attachment](/workspace/chat/download-media-attachments)\n- [Get metadata about a message attachment](/workspace/chat/get-media-attachments)"]]
