Ce guide explique comment utiliser la méthode upload sur la ressource Media de l'API Google Chat pour importer un fichier multimédia dans Google Chat, puis l'ajouter à un message.
Lorsque l'utilisateur envoie un message à votre application, Google Chat déclenche un événement d'interaction MESSAGE.
L'événement d'interaction reçu par votre application inclut un corps de requête, qui est la charge utile JSON représentant l'événement d'interaction, y compris les pièces jointes. Les données de la pièce jointe varient selon qu'il s'agit d'un contenu importé (fichier local) ou d'un fichier stocké sur Drive. La ressource Media représente un fichier importé dans Google Chat, comme des images, des vidéos et des documents.
La ressource Attachment représente une instance de contenu multimédia (un fichier) jointe à un message. La ressource Attachment inclut les métadonnées de la pièce jointe, comme l'emplacement où elle est enregistrée.
Créez des identifiants d'ID client OAuth pour une application de bureau. Pour exécuter l'exemple de ce guide, enregistrez les identifiants dans un fichier JSON nommé credentials.json dans votre répertoire local.
Définissez attachment comme réponse à l'appel de la méthode upload sur la ressource Media. Le champ attachment accepte une liste.
L'exemple suivant importe un fichier image PNG et le joint à un message.
Python
Dans votre répertoire de travail, créez un fichier nommé chat_media_and_attachment_upload.py.
Incluez le code suivant dans chat_media_and_attachment_upload.py :
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.

Dans le code, remplacez SPACE par le nom de l'espace dans lequel importer la pièce jointe. Vous pouvez l'obtenir à partir de la méthode spaces.list de l'API Chat ou de l'URL d'un espace.
Dans votre répertoire de travail, compilez et exécutez l'exemple :
python3chat_media_and_attachment_upload.py
L'API Chat renvoie un corps de réponse contenant attachmentDataRef avec des informations sur le fichier importé.
Limites et points à prendre en compte
Lorsque vous vous préparez à importer des fichiers et à les joindre à des messages, tenez compte des limites et des points suivants :
Vous pouvez importer des fichiers de 200 Mo maximum.

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)"]]
