从线程获取最后一封电子邮件并获取 csv 附件

Question

我试图获取最后一封电子邮件线程的 csv 附件 ID，但我在编写代码时遇到了困难。有人能帮忙吗？

var searcher = "Automail-"+CurrentDateFormat+".csv";

var searchedThreads = GmailApp.search( 'subject:""'+searcher+'""')[0];

var id = searchedThreads.getId(); 
var dateMessage = GmailApp.getMessageById(id).getDate();
var contentmessage = GmailApp.getMessageById(id).getPlainBody();

var attachtextLength = GmailApp.getMessageById(id).getAttachments()[0].getDataAsString().length;
if (attachtextLength >= 150){

var attachtext = GmailApp.getMessageById(id).getAttachments()[0].getDataAsString();

UpdateSheet(attachtext);

Answer 1

如果您要查找多个线程中最后一个匹配的线程....

var searchedThreads = GmailApp.search( 'subject:""'+searcher+'""');
searchedThreads = searchedThreads[searchedThreads.length-1];

如果您正在查找最后一个附件....

var attachtext = GmailApp.getMessageById(id).getAttachments();
attachtext = attachtext[attachtext.length-1].getDataAsString();

希望对您有所帮助。
