Il servizio Gmail avanzato ti consente di utilizzare l'API Gmail in
Apps Script. Proprio come il servizio Gmail integrato di Apps Script,
questa API consente agli script di trovare e modificare thread, messaggi ed etichette in una
casella di posta Gmail. Nella maggior parte dei casi, il servizio integrato è più facile da usare, ma questo
servizio avanzato fornisce alcune funzionalità aggiuntive e l'accesso a informazioni
più dettagliate sui contenuti di Gmail.
Riferimento
Per informazioni dettagliate su questo servizio, consulta la
documentazione di riferimento per l'API Gmail.
Come tutti i servizi avanzati in Apps Script, il servizio Gmail avanzato utilizza gli stessi oggetti, metodi e parametri dell'API pubblica. Per ulteriori informazioni, consulta Come vengono determinate le firme dei metodi.
Il codice di esempio riportato di seguito utilizza la versione 1 dell'API.
Elencare le informazioni sulle etichette
Il seguente esempio mostra come elencare tutte le informazioni sulle etichette dell'utente.
Sono inclusi nome, tipo, ID e impostazioni di visibilità dell'etichetta.
/** * Lists the user's labels, including name, type, * ID and visibility information. */functionlistLabelInfo(){try{constresponse=Gmail.Users.Labels.list('me');for(leti=0;i < response.labels.length;i++){constlabel=response.labels[i];console.log(JSON.stringify(label));}}catch(err){console.log(err);}}
Elencare gli snippet della posta in arrivo
Il seguente esempio mostra come elencare gli snippet di testo associati a ogni thread nella posta in arrivo dell'utente. Nota l'utilizzo dei token di pagina per accedere all'elenco completo dei risultati.
/** * Lists, for each thread in the user's Inbox, a * snippet associated with that thread. */functionlistInboxSnippets(){try{letpageToken;do{constthreadList=Gmail.Users.Threads.list('me',{q:'label:inbox',pageToken:pageToken});if(threadList.threads && threadList.threads.length > 0){threadList.threads.forEach(function(thread){console.log('Snippet: %s',thread.snippet);});}pageToken=threadList.nextPageToken;}while(pageToken);}catch(err){console.log(err);}}
Elenca la cronologia recente
Il seguente esempio mostra come registrare la cronologia dell'attività recente.
Nello specifico, questo esempio recupera l'ID record della cronologia associato al messaggio inviato più di recente dall'utente, quindi registra gli ID messaggio di ogni messaggio modificato da quel momento. Ogni messaggio modificato viene registrato
una sola volta, indipendentemente dal numero di eventi di modifica nei record della cronologia. Nota l'utilizzo dei token di pagina per accedere all'elenco completo dei risultati.
/** * Gets a history record ID associated with the most * recently sent message, then logs all the message IDs * that have changed since that message was sent. */functionlogRecentHistory(){try{// Get the history ID associated with the most recent// sent message.constsent=Gmail.Users.Threads.list('me',{q:'label:sent',maxResults:1});if(!sent.threads||!sent.threads[0]){console.log('No sent threads found.');return;}consthistoryId=sent.threads[0].historyId;// Log the ID of each message changed since the most// recent message was sent.letpageToken;constchanged=[];do{constrecordList=Gmail.Users.History.list('me',{startHistoryId:historyId,pageToken:pageToken});consthistory=recordList.history;if(history && history.length > 0){history.forEach(function(record){record.messages.forEach(function(message){if(changed.indexOf(message.id)===-1){changed.push(message.id);}});});}pageToken=recordList.nextPageToken;}while(pageToken);changed.forEach(function(id){console.log('Message Changed: %s',id);});}catch(err){console.log(err);}}
Elenco di messaggi
Il seguente esempio mostra come elencare i messaggi non letti dell'utente Gmail.
/** * Lists unread messages in the user's inbox using the advanced Gmail service. */functionlistMessages(){// The special value 'me' indicates the authenticated user.constuserId='me';// Define optional parameters for the request.constoptions={maxResults:10,// Limit the number of messages returned.q:'is:unread',// Search for unread messages.};try{// Call the Gmail.Users.Messages.list method.constresponse=Gmail.Users.Messages.list(userId,options);constmessages=response.messages;console.log('Unread Messages:');for(constmessageofmessages){console.log(`- Message ID: ${message.id}`);}}catch(err){// Log any errors to the Apps Script execution log.console.log(`Failed with error: ${err.message}`);}}

Much like Apps Script's [built-in Gmail service](/apps-script/reference/gmail),\nthis API allows scripts to find and modify threads, messages, and labels in a\nGmail mailbox. In most cases, the built-in service is easier to use, but this\nadvanced service provides a few extra features and access to more detailed\ninformation about Gmail content.\n| **Note:** This is an advanced service that must be [enabled before use](/apps-script/guides/services/advanced).\n\nReference\n---------\n\nFor detailed information on this service, see the\n[reference documentation](/gmail/api/v1/reference) for the Gmail API.\nLike all advanced services in Apps Script, the advanced Gmail service uses the\nsame objects, methods, and parameters as the public API. For more information, see [How method signatures are determined](/apps-script/guides/services/advanced#how_method_signatures_are_determined).\n| **Note:** To improve performance, the Gmail API often restricts the amount of information returned from `list` requests to thread, message or label IDs and other simple information. More detailed information about a particular thread, message or label can be obtained by issuing a follow-up `get` request using the associated ID.\n\nTo report issues and find other support, see the\n[Gmail support guide](/gmail/api/support).\n\nSample code\n-----------\n\nThe sample code below uses [version 1](/gmail/api/v1/reference) of the API.\n\n### List label information\n\nThe following example demonstrates how to list all the user's label information.\nThis includes the label name, type, ID and visibility settings. \nadvanced/gmail.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/gmail.gs) \n\n```javascript\n/**\n * Lists the user's labels, including name, type,\n * ID and visibility information.\n */\nfunction listLabelInfo() {\n try {\n const response =\n Gmail.Users.Labels.list('me');\n for (let i = 0; i \u003c response.labels.length; i++) {\n const label = response.labels[i];\n console.log(JSON.stringify(label));\n }\n } catch (err) {\n console.log(err);\n }\n}\n```\n\n### List inbox snippets\n\nThe following example demonstrates how to list text snippets associated with\neach thread in the user's Inbox. Notice the use of page tokens to access the\nfull list of results. \nadvanced/gmail.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/gmail.gs) \n\n```javascript\n/**\n * Lists, for each thread in the user's Inbox, a\n * snippet associated with that thread.\n */\nfunction listInboxSnippets() {\n try {\n let pageToken;\n do {\n const threadList = Gmail.Users.Threads.list('me', {\n q: 'label:inbox',\n pageToken: pageToken\n });\n if (threadList.threads && threadList.threads.length \u003e 0) {\n threadList.threads.forEach(function (thread) {\n console.log('Snippet: %s', thread.snippet);\n });\n }\n pageToken = threadList.nextPageToken;\n } while (pageToken);\n } catch (err) {\n console.log(err);\n }\n}\n```\n\n### List recent history\n\nThe following example demonstrates how to log recent activity history.\nSpecifically, this example recovers the history record ID associated with the\nuser's most recently sent message, and then logs the message IDs of every\nmessage that has changed since that time. Each changed message is only logged\nonce, no matter how many change events are in the history records. Notice the\nuse of page tokens to access the full list of results. \nadvanced/gmail.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/gmail.gs) \n\n```javascript\n/**\n * Gets a history record ID associated with the most\n * recently sent message, then logs all the message IDs\n * that have changed since that message was sent.\n */\nfunction logRecentHistory() {\n try {\n // Get the history ID associated with the most recent\n // sent message.\n const sent = Gmail.Users.Threads.list('me', {\n q: 'label:sent',\n maxResults: 1\n });\n if (!sent.threads || !sent.threads[0]) {\n console.log('No sent threads found.');\n return;\n }\n const historyId = sent.threads[0].historyId;\n\n // Log the ID of each message changed since the most\n // recent message was sent.\n let pageToken;\n const changed = [];\n do {\n const recordList = Gmail.Users.History.list('me', {\n startHistoryId: historyId,\n pageToken: pageToken\n });\n const history = recordList.history;\n if (history && history.length \u003e 0) {\n history.forEach(function (record) {\n record.messages.forEach(function (message) {\n if (changed.indexOf(message.id) === -1) {\n changed.push(message.id);\n }\n });\n });\n }\n pageToken = recordList.nextPageToken;\n } while (pageToken);\n\n changed.forEach(function (id) {\n console.log('Message Changed: %s', id);\n });\n } catch (err) {\n console.log(err);\n }\n}\n```\n\n### List messages\n\nThe following example demonstrates how to list the Gmail user's\nunread messages. \nadvanced/gmail.gs \n[View on GitHub](https://github.com/googleworkspace/apps-script-samples/blob/main/advanced/gmail.gs) \n\n```javascript\n/**\n * Lists unread messages in the user's inbox using the advanced Gmail service.\n */\nfunction listMessages() {\n // The special value 'me' indicates the authenticated user.\n const userId = 'me';\n\n // Define optional parameters for the request.\n const options = {\n maxResults: 10, // Limit the number of messages returned.\n q: 'is:unread', // Search for unread messages.\n };\n\n try {\n // Call the Gmail.Users.Messages.list method.\n const response = Gmail.Users.Messages.list(userId, options);\n const messages = response.messages;\n console.log('Unread Messages:');\n\n for (const message of messages) {\n console.log(`- Message ID: ${message.id}`);\n }\n } catch (err) {\n // Log any errors to the Apps Script execution log.\n console.log(`Failed with error: ${err.message}`);\n }\n}\n```"]]
