Le service Chat avancé vous permet d'utiliser l'API Google Chat dans Apps Script. Cette API permet aux scripts de rechercher, de créer et de modifier des espaces Chat, d'ajouter des membres à des espaces ou d'en supprimer, et de lire ou de publier des messages contenant du texte, des fiches, des pièces jointes et des réactions.
Prérequis
Une application Google Chat Apps Script configurée sur la page de configuration de l'API Chat dans la console Google Cloud. Le projet Apps Script de l'application doit utiliser un projet Google Cloud standard au lieu de celui créé automatiquement par défaut pour les projets Apps Script. Pour créer une application Google Chat compatible, consultez Créer une application Google Chat à l'aide de Google Apps Script.
Pour en savoir plus sur ce service, consultez la documentation de référence de l'API Chat.
Comme tous les services avancés d'Apps Script, le service Chat utilise les mêmes objets, méthodes et paramètres que l'API publique.
Exemple de code
Ces exemples vous montrent comment effectuer des actions courantes de l'API Google Chat à l'aide du service avancé.
Publier un message avec des identifiants utilisateur
L'exemple suivant montre comment publier un message dans un espace de discussion au nom de l'utilisateur.
Ajoutez le champ d'application de l'autorisation chat.messages.create au fichier appsscript.json du projet Apps Script :
/** * 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);}}
Publier un message avec les identifiants de l'application
L'exemple suivant montre comment publier un message dans un espace de discussion Chat au nom de l'application. L'utilisation du service Chat avancé avec un compte de service ne nécessite pas de spécifier des niveaux d'autorisation dans appsscript.json. Pour en savoir plus sur l'authentification avec des comptes de service, consultez S'authentifier en tant qu'application Google Chat.
/** * Posts a new message to the specified space on behalf of the app. * @param {string} spaceName The resource name of the space. */functionpostMessageWithAppCredentials(spaceName){try{// See https://developers.google.com/chat/api/guides/auth/service-accounts// for details on how to obtain a service account OAuth token.constappToken=getToken_();constmessage={'text':'Hello world!'};Chat.Spaces.Messages.create(message,spaceName,{},// Authenticate with the service account token.{'Authorization':'Bearer '+appToken});}catch(err){// TODO (developer) - Handle exceptionconsole.log('Failed to create message with error %s',err.message);}}
Obtenir un espace
L'exemple suivant montre comment obtenir des informations sur un espace de discussion.
Ajoutez le champ d'application de l'autorisation chat.spaces.readonly au fichier appsscript.json du projet Apps Script :
/** * Gets information about a Chat space. * @param {string} spaceName The resource name of the space. */functiongetSpace(spaceName){try{constspace=Chat.Spaces.get(spaceName);console.log('Space display name: %s',space.displayName);console.log('Space type: %s',space.spaceType);}catch(err){// TODO (developer) - Handle exceptionconsole.log('Failed to get space with error %s',err.message);}}
Créer un espace
L'exemple suivant montre comment créer un espace Chat.
Ajoutez le champ d'application de l'autorisation chat.spaces.create au fichier appsscript.json du projet Apps Script :
/** * Creates a new Chat space. */functioncreateSpace(){try{constspace={'displayName':'New Space','spaceType':'SPACE'};Chat.Spaces.create(space);}catch(err){// TODO (developer) - Handle exceptionconsole.log('Failed to create space with error %s',err.message);}}
Membres des listes
L'exemple suivant montre comment lister tous les membres d'un espace de discussion.
Ajoutez le champ d'application de l'autorisation chat.memberships.readonly au fichier appsscript.json du projet Apps Script :
/** * Lists all the members of a Chat space. * @param {string} spaceName The resource name of the space. */functionlistMemberships(spaceName){letresponse;letpageToken=null;try{do{response=Chat.Spaces.Members.list(spaceName,{pageSize:10,pageToken:pageToken});if(!response.memberships||response.memberships.length===0){pageToken=response.nextPageToken;continue;}response.memberships.forEach((membership)=>console.log('Member resource name: %s (type: %s)',membership.name,membership.member.type));pageToken=response.nextPageToken;}while(pageToken);}catch(err){// TODO (developer) - Handle exceptionconsole.log('Failed with error %s',err.message);}}
Résoudre les problèmes
Si vous rencontrez l'erreur Error 400: invalid_scope avec le message d'erreur Some requested scopes cannot be shown, cela signifie que vous n'avez spécifié aucun champ d'application d'autorisation dans le fichier appsscript.json du projet Apps Script. Dans la plupart des cas, Apps Script détermine automatiquement les autorisations dont un script a besoin. Toutefois, lorsque vous utilisez le service avancé Chat, vous devez ajouter manuellement les autorisations utilisées par votre script au fichier manifeste de votre projet Apps Script. Consultez Définir des niveaux d'accès explicites.
Pour résoudre l'erreur, ajoutez les niveaux d'autorisation appropriés au fichier appsscript.json du projet Apps Script dans le cadre du tableau oauthScopes. Par exemple, pour appeler la méthode spaces.messages.create, ajoutez ce qui suit :
Pour télécharger une pièce jointe ou appeler une méthode d'aperçu pour les développeurs, utilisez plutôt UrlFetchApp.

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."]]
