Advanced Chat 服務可讓您在 Apps Script 中使用 Google Chat API。這個 API 可讓指令碼尋找、建立及修改 Chat 聊天室,在聊天室中新增或移除成員,以及讀取或發布含有文字、資訊卡、附件和表情符號的訊息。
必要條件
在 Google Cloud 控制台的 Chat API 設定頁面中設定的 Apps Script Google Chat 應用程式。應用程式的 Apps Script 專案必須使用標準 Google Cloud 專案,而非系統為 Apps Script 專案自動建立的預設專案。如要建立相容的 Google Chat 應用程式,請參閱「使用 Google Apps Script 建構 Google Chat 應用程式」。
/** * Posts a new message to the specified space on behalf of the user. * @param {string} spaceName The resource name of the space. */functionpostMessageWithUserCredentials(spaceName){try{constmessage={'text':'Hello world!'};Chat.Spaces.Messages.create(message,spaceName);}catch(err){// TODO (developer) - Handle exceptionconsole.log('Failed to create message with error %s',err.message);}}
使用應用程式憑證發布訊息
下列範例說明如何代表應用程式將訊息發布至 Google Chat 空間。使用進階 Google Chat 服務和服務帳戶時,您不需要在 appsscript.json 中指定授權範圍。如要瞭解如何使用服務帳戶進行驗證,請參閱「以 Google Chat 應用程式身分進行驗證」。

This API allows scripts to find, create, and modify\nChat spaces, add or remove members to spaces, and read or post\nmessages with text, cards, attachments, and reactions.\n\nPrerequisites\n-------------\n\n- An Apps Script Google Chat app configured on the Chat API configuration page in the Google Cloud console. The app's Apps Script project must use a standard Google Cloud project instead of the default one created automatically for Apps Script projects. To create a compatible Google Chat app, see [Build a Google Chat app with Google Apps Script](/workspace/add-ons/chat/quickstart-apps-script).\n- Authentication configured for the Chat app. Performing an action on behalf of a user requires [user authentication](/chat/api/guides/auth/users). Performing an action as the Chat app requires [app authentication with a service account](/chat/api/guides/auth/service-accounts). To check which form of authentication a Chat API method supports, see [Types of required authentication for Google Chat API calls](/chat/api/guides/auth#asynchronous-chat-calls).\n\n| **Note:** This is an advanced service that you must [turn on before use](/apps-script/guides/services/advanced).\n\nReference\n---------\n\nFor more information about this service, see the\n[Chat API reference documentation](/chat/api/reference/rest).\nLike all advanced services in Apps Script, the\nChat service uses the same objects, methods, and parameters as\nthe public API.\n\nSample code\n-----------\n\nThese samples show you how to perform common\n[Google Chat API](/chat/api/guides)\nactions using the advanced service.\n\n### Post a message with user credentials\n\nThe following example demonstrates how to post a message to a\nChat space on behalf of the user.\n\n1. Add the `chat.messages.create` authorization scope to the\n Apps Script project's `appsscript.json` file:\n\n \"oauthScopes\": [\n \"https://www.googleapis.com/auth/chat.messages.create\"\n ]\n\n2. Add a function like this one to the Apps Script project's\n code:\n\n advanced/chat.gs \n [View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/chat.gs) \n\n ```javascript\n /**\n * Posts a new message to the specified space on behalf of the user.\n * @param {string} spaceName The resource name of the space.\n */\n function postMessageWithUserCredentials(spaceName) {\n try {\n const message = {'text': 'Hello world!'};\n Chat.Spaces.Messages.create(message, spaceName);\n } catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed to create message with error %s', err.message);\n }\n }\n ```\n\n### Post a message with app credentials\n\nThe following example demonstrates how to post a message to a\nChat space on behalf of the app. Using the advanced\nChat service with a service account doesn't require you to\nspecify authorization scopes in `appsscript.json`. For details about\nauthentication with service accounts, see\n[Authenticate as a Google Chat app](/chat/api/guides/auth/service-accounts). \nadvanced/chat.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/chat.gs) \n\n```javascript\n/**\n * Posts a new message to the specified space on behalf of the app.\n * @param {string} spaceName The resource name of the space.\n */\nfunction postMessageWithAppCredentials(spaceName) {\n try {\n // See https://developers.google.com/chat/api/guides/auth/service-accounts\n // for details on how to obtain a service account OAuth token.\n const appToken = getToken_();\n const message = {'text': 'Hello world!'};\n Chat.Spaces.Messages.create(\n message,\n spaceName,\n {},\n // Authenticate with the service account token.\n {'Authorization': 'Bearer ' + appToken});\n } catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed to create message with error %s', err.message);\n }\n}\n```\n\n### Get a space\n\nThe following example demonstrates how to get information about a\nChat space.\n\n1. Add the `chat.spaces.readonly` authorization scope to the\n Apps Script project's `appsscript.json` file:\n\n \"oauthScopes\": [\n \"https://www.googleapis.com/auth/chat.spaces.readonly\"\n ]\n\n2. Add a function like this one to the Apps Script project's\n code:\n\n advanced/chat.gs \n [View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/chat.gs) \n\n ```javascript\n /**\n * Gets information about a Chat space.\n * @param {string} spaceName The resource name of the space.\n */\n function getSpace(spaceName) {\n try {\n const space = Chat.Spaces.get(spaceName);\n console.log('Space display name: %s', space.displayName);\n console.log('Space type: %s', space.spaceType);\n } catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed to get space with error %s', err.message);\n }\n }\n ```\n\n### Create a space\n\nThe following example demonstrates how to create a Chat space.\n\n1. Add the `chat.spaces.create` authorization scope to the\n Apps Script project's `appsscript.json` file:\n\n \"oauthScopes\": [\n \"https://www.googleapis.com/auth/chat.spaces.create\"\n ]\n\n2. Add a function like this one to the Apps Script project's\n code:\n\n advanced/chat.gs \n [View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/chat.gs) \n\n ```javascript\n /**\n * Creates a new Chat space.\n */\n function createSpace() {\n try {\n const space = {'displayName': 'New Space', 'spaceType': 'SPACE'};\n Chat.Spaces.create(space);\n } catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed to create space with error %s', err.message);\n }\n }\n ```\n\n### List memberships\n\nThe following example demonstrates how to list all the members of a\nChat space.\n\n1. Add the `chat.memberships.readonly` authorization scope to the\n Apps Script project's `appsscript.json` file:\n\n \"oauthScopes\": [\n \"https://www.googleapis.com/auth/chat.memberships.readonly\"\n ]\n\n2. Add a function like this one to the Apps Script project's\n code:\n\n advanced/chat.gs \n [View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/chat.gs) \n\n ```javascript\n /**\n * Lists all the members of a Chat space.\n * @param {string} spaceName The resource name of the space.\n */\n function listMemberships(spaceName) {\n let response;\n let pageToken = null;\n try {\n do {\n response = Chat.Spaces.Members.list(spaceName, {\n pageSize: 10,\n pageToken: pageToken\n });\n if (!response.memberships || response.memberships.length === 0) {\n pageToken = response.nextPageToken;\n continue;\n }\n response.memberships.forEach((membership) =\u003e console.log(\n 'Member resource name: %s (type: %s)',\n membership.name,\n membership.member.type));\n pageToken = response.nextPageToken;\n } while (pageToken);\n } catch (err) {\n // TODO (developer) - Handle exception\n console.log('Failed with error %s', err.message);\n }\n }\n ```\n\nTroubleshoot\n------------\n\nIf you encounter `Error 400: invalid_scope` with the error message\n`Some requested scopes cannot be shown`,\nit means you haven't specified any authorization scopes in the\nApps Script project's `appsscript.json` file. In most cases,\nApps Script automatically determines what scopes a script needs,\nbut when you use the Chat advanced service, you must manually add\nthe authorization scopes that your script uses to your\nApps Script project's manifest file. See\n[Setting explicit scopes](/apps-script/concepts/scopes#setting_explicit_scopes).\n\nTo resolve the error, add the appropriate authorization scopes\nto the Apps Script project's `appsscript.json` file as part of\nthe `oauthScopes` array. For example, to call the\n[`spaces.messages.create`](/chat/api/reference/rest/v1/spaces.messages/create)\nmethod, add the following: \n\n \"oauthScopes\": [\n \"https://www.googleapis.com/auth/chat.messages.create\"\n ]\n\nLimits and considerations\n-------------------------\n\nThe Advanced Chat service doesn't support:\n\n- The Chat API method [`media.download`](/chat/api/reference/rest/v1/media/download).\n- Chat API methods available in [Developer Preview](/workspace/preview)\n\nTo download a message attachment or call a developer preview method, use\n[`UrlFetchApp`](/apps-script/reference/url-fetch/url-fetch-app) instead."]]
