应用程序脚本保存上一封邮件的附件

Question

我需要一些帮助来保存上次邮件的附件。每天早上和晚上我都会收到自动发送的电子邮件。

我在网络上找到了一个脚本，但它需要一些编辑。邮件在上午 9 点和下午 4 点收到，因此脚本必须仅获取今天的最后一封信，并将附件保存在文件夹“GmailToDrive”中并替换旧文件。

我只需要保存来自特殊发件人的邮件（一封邮件）。其他发件人不符合脚本。

你能帮我吗，我需要在这里更改或编辑什么？非常感谢各位朋友！）

function getGmailLabel_(name){
  var label = GmailApp.getUserLabelByName(name);
  if(!label){

  }
  return label;
}

//this function will check for filextension type.
// and return boolean
function checkIfDefinedType_(attachment){
  var fileName = attachment.getName();
  var temp = fileName.split('.');
  var fileExtension = temp[temp.length-1].toLowerCase();
  if(fileTypesToExtract.indexOf(fileExtension) !== -1) return true;

我明白，编辑后我终于可以在上午 9 点和下午 4 点之后准时将其放入触发器）））

在您的脚本下方，编辑了 3 行。

1. 在查询[编辑]中添加您要查看的电子邮件，并且仅在过去 24 小时内收到的邮件
2. 添加 if 语句仅检查未读邮件（如果您手动阅读，请将其恢复为未读以使脚本正常工作）
3. 检查所有邮件后将线程设置为已读

function GmailToDrive(){
  var query = '';
  //filename:jpg OR filename:tif OR filename:gif OR fileName:png OR filename:bmp OR filename:svg'; //'after:'+formattedDate+
  for(var i in fileTypesToExtract){
    query += (query === '' ?('filename:'+fileTypesToExtract[i]) : (' OR filename:'+fileTypesToExtract[i]));
  }

  //ADD the only email adress you want to check + EDIT : only last 24h emails
  query = 'in:inbox has:nouserlabels ' + query + ' AND from:sender@sender AND newer_than:1d';

  var threads = GmailApp.search(query);
  var label = getGmailLabel_(labelName);
  var parentFolder;
  if(threads.length > 0){
    parentFolder = getFolder_(folderName);
  }
  var root = DriveApp.getRootFolder();
  for(var i in threads){
    var mesgs = threads[i].getMessages();
    for(var j in mesgs){

      //ADD: check if the mail is unread:
      if (mesgs[j].isUnread()) {

        var attachments = mesgs[j].getAttachments();
        for(var k in attachments){
          var attachment = attachments[k];
          var isDefinedType = checkIfDefinedType_(attachment);
          if(!isDefinedType) continue;
            var attachmentBlob = attachment.copyBlob();
            var file = DriveApp.createFile(attachmentBlob);
            parentFolder.addFile(file);
            root.removeFile(file);
          }
        }

      } // close if unread
    } // close for msg loop

    //ADD: Set thread (all mail included) as read
    GmailApp.markThreadRead(threads[i]);

    threads[i].addLabel(label);
  }
}

你的回应太棒了！我让它工作了 4-5 次，但现在我得到了

ReferenceError：getGmailLabel_未定义 GmailToDrive @ 我的 Gmail Processor.gs：17

我不明白为什么。有什么建议吗？
