In diesem Leitfaden wird beschrieben, wie Sie mit der Methode upload für die Ressource Media der Google Chat API Medien (eine Datei) in Google Chat hochladen und dann an eine Nachricht anhängen.
Wenn der Nutzer eine Nachricht an Ihre App sendet, wird in Google Chat ein MESSAGE-Interaktionsereignis gesendet.
Das von Ihrer App empfangene Interaktionsereignis enthält einen Anfragetext, der die JSON-Nutzlast des Interaktionsereignisses darstellt, einschließlich aller Anhänge. Die Daten im Anhang unterscheiden sich je nachdem, ob es sich um hochgeladene Inhalte (eine lokale Datei) oder eine in Drive gespeicherte Datei handelt. Die Media-Ressource stellt eine in Google Chat hochgeladene Datei wie Bilder, Videos und Dokumente dar.
Die Attachment-Ressource stellt eine Instanz von Medien dar, also eine Datei, die an eine Nachricht angehängt ist. Die Ressource Attachment enthält die Metadaten des Anhangs, z. B. den Speicherort.
Wenn Sie Medien hochladen und an eine Nachricht anhängen möchten, übergeben Sie Folgendes in Ihrer Anfrage:
Geben Sie den Autorisierungsbereich chat.messages.create oder chat.messages an.
Rufen Sie die folgenden Google Chat-Methoden auf:
Rufen Sie zum Hochladen der Datei die Methode upload für die Ressource Media auf.
Setzen Sie parent auf den Namen des Gruppenbereichs, in dem sich die Datei befindet.
Legen Sie in body (dem Anfragetext) filename auf den Namen des hochgeladenen Dateianhangs fest.
Legen Sie media_body als Instanz der hochzuladenden Datei fest.
Rufen Sie zum Erstellen einer Nachricht mit der hochgeladenen Datei als Anhang die Methode create> für die Ressource Messages auf.
Legen Sie attachment als Antwort auf den Aufruf der upload-Methode für die Media-Ressource fest. Das Feld attachment akzeptiert eine Liste.
Im folgenden Beispiel wird eine PNG-Bilddatei hochgeladen und an eine Nachricht angehängt.
Python
Erstellen Sie in Ihrem Arbeitsverzeichnis eine Datei mit dem Namen chat_media_and_attachment_upload.py.
Fügen Sie den folgenden Code in chat_media_and_attachment_upload.py ein:
fromgoogle_auth_oauthlib.flowimportInstalledAppFlowfromgoogleapiclient.discoveryimportbuildfromgoogleapiclient.httpimportMediaFileUpload# 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"]defmain():''' Authenticates with Chat API via user credentials, then uploads a file as media, creates a message, and attaches the file to the message.

Ersetzen Sie im Code SPACE durch den Namen des Bereichs, in den Sie den Anhang hochladen möchten. Sie können den Namen über die spaces.list-Methode in der Chat API oder über die URL eines Bereichs abrufen.
Erstellen Sie das Beispiel in Ihrem Arbeitsverzeichnis und führen Sie es aus:
python3chat_media_and_attachment_upload.py
Die Chat API gibt einen Antworttext mit attachmentDataRef zurück, der Details zur hochgeladenen Datei enthält.
Einschränkungen und Überlegungen

File size should not exceed 200MB and some file types are not supported.\n"],null,["# Upload media as a file attachment\n\nThis guide explains how to use the `upload` method on the `Media` resource of\nthe Google Chat API to upload media (a file) to Google Chat and then attach it to\na message.\n\nWhen the user sends a message to your app, Google Chat dispatches a\n[`MESSAGE` interaction event](/workspace/chat/events#message).\nThe interaction event received by your app includes a request body, which is the\nJSON payload representing the interaction event, including any attachments. 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)"]]
