Zadbaj o dobrą organizację dzięki kolekcji
Zapisuj i kategoryzuj treści zgodnie ze swoimi preferencjami.
Ten przewodnik wyjaśnia, jak używać metody upload w zasobie Media interfejsu Google Chat API do przesyłania multimediów (pliku) do Google Chat, a następnie dołączania ich do wiadomości.
Gdy użytkownik wyśle wiadomość do Twojej aplikacji, Google Chat wyśle MESSAGEzdarzenie interakcji.
Zdarzenie interakcji otrzymane przez aplikację zawiera treść żądania, czyli ładunek JSON reprezentujący zdarzenie interakcji, w tym wszelkie załączniki. Dane w załączniku różnią się w zależności od tego, czy załącznik jest przesłaną treścią (plik lokalny), czy plikiem przechowywanym na Dysku. MediaZasób
reprezentuje plik przesłany do Google Chat, np. obraz, film lub dokument.
AttachmentZasób reprezentuje instancję multimediów, czyli plik dołączony do wiadomości. AttachmentZasób zawiera metadane załącznika, takie jak miejsce jego zapisania.
Utwórz dane logowania identyfikatora klienta OAuth dla aplikacji na komputery. Aby uruchomić przykład w tym przewodniku, zapisz dane logowania jako plik JSON o nazwie credentials.json w katalogu lokalnym.
Ustaw attachment jako odpowiedź z wywołania metody upload na zasobie Media. Pole attachment
akceptuje listę.
W tym przykładzie przesyłany jest plik obrazu PNG, który jest dołączany do wiadomości.
Python
W katalogu roboczym utwórz plik o nazwie chat_media_and_attachment_upload.py.
Dodaj do pliku chat_media_and_attachment_upload.py ten kod:
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.

W kodzie zastąp SPACE nazwą przestrzeni, do której chcesz przesłać załącznik. Możesz ją uzyskać za pomocą metody spaces.list w interfejsie Chat API lub z adresu URL przestrzeni.
W katalogu roboczym skompiluj i uruchom przykład:
python3chat_media_and_attachment_upload.py
Interfejs Chat API zwraca treść odpowiedzi zawierającą obiekt attachmentDataRef ze szczegółowymi informacjami o przesłanym pliku.
Limity i kwestie do rozważenia
Podczas przygotowywania plików do przesłania i dołączania ich do wiadomości pamiętaj o tych limitach i kwestiach:
Możesz przesyłać pliki o rozmiarze do 200 MB.
Niektóre typy plików nie są obsługiwane i nie można ich przesłać. Więcej informacji znajdziesz w artykule Typy plików blokowane w Google Chat.

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)"]]
