我正在尝试使用 google 应用程序脚本将特定标签下的电子邮件转储到 Google Docs 电子表格。我想将线程中的每个电子邮件正文列为单独的行，这样如果一个线程有 9 条消息链，则每条消息都单独列出（没有链）。

我已经设法将它保存到每个消息正文 + 其整个前一个线程的存储位置，在一个单元格中，我可以在一个单元格中获取整个线程。但这不是我想要的。

此代码将把线程的整个主体排成一行。

function getEmails() {
  clearCanvas();
  var label = GmailApp.getUserLabelByName(LabelWithEmails);
  var threads = label.getThreads();

  // var threads = GmailApp.getInboxThreads(0, 50);
  var row = getFirstRow() + 1;
  var firstmessageId = getfirstmsgid();
  UserProperties.setProperty("firstmsgid", firstmessageId);
  spreadsheet.toast("Loading emails..Please wait. It could take few seconds", "Status", -1);

  var messages = GmailApp.getMessagesForThreads(threads); //gets messages in 2D array
  for (i = 0; i < 5; ++i)
  {
   try {
       j = messages[i].length; //to process most recent conversation in thread (contains messages from previous conversations as well, reduces redundancy
       messageBody = messages[i][j-1].getBody(); //gets body of message in HTML
       messageSubject = messages[i][j-1].getSubject();
       messageDate = messages[i][j-1].getDate();
       messageFrom = messages[i][j-1].getFrom();

       Logger.log("Message Subject:" + messageSubject);
       Logger.log("Message Date:" + messageDate);
       Logger.log("Message From:" + messageFrom);

       sheet.getRange(row, 1).setValue(messageFrom);
       sheet.getRange(row, 2).setValue(messageSubject);
       sheet.getRange(row, 3).setValue(messageDate);
       sheet.getRange(row, 4).setValue(getTextFromHtml(messageBody));
       row++;
    } catch (error) {
        spreadsheet.toast("Error Occured. Report it @ http://techawakening.org/", "Status", -1);
    }

    if (i == threads.length - 1) {
        spreadsheet.toast("Successfully loaded emails.", "Status", -1);
        spreadsheet.toast("Now mark emails to be forwarded by changing the background color of the cells to green. Then select Forward->Forward selected emails", "Status", -1);
    }

  }
}

这会将每个消息正文（包括它的前一个线程/消息链）排成一行。

function getEmails() {
clearCanvas();
var label = GmailApp.getUserLabelByName(LabelWithEmails);
var threads = label.getThreads();

// var threads = GmailApp.getInboxThreads(0, 50);
var row = getFirstRow() + 1;
var firstmessageId = getfirstmsgid();
UserProperties.setProperty("firstmsgid", firstmessageId);
spreadsheet.toast("Loading emails..Please wait. It could take few seconds", "Status", -1);

var messages = GmailApp.getMessagesForThreads(threads); //gets messages in 2D array
// messages.length
// jknipp - working except it keeps the thread chain
for (var i = 0; i < threads.length; i++) {
    try {
        var messages = threads[i].getMessages();
        for (var m = 0; m < messages.length; m++) {
            sheet.getRange(row, 1).setValue(messages[m].getFrom());
            sheet.getRange(row, 2).setValue(messages[m].getSubject());
            sheet.getRange(row, 3).setValue(messages[m].getDate());
            sheet.getRange(row, 4).setValue(getTextFromHtml(messages[m].getBody()));

            row++;
        }
    } catch (error) {
        spreadsheet.toast("Error Occured. Report it @ http://techawakening.org/", "Status", -1);
    }

    if (i == threads.length - 1) {
        spreadsheet.toast("Successfully loaded emails.", "Status", -1);
        spreadsheet.toast("Now mark emails to be forwarded by changing the background color of the cells to green. Then select Forward->Forward selected emails", "Status", -1);
    }
  }
}

通过确定“先前对话”的开始位置，我只能提取电子邮件的正文。

var sheet = SpreadsheetApp.getActiveSheet();
var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
var LabelWithEmails = sheet.getRange(3, 2).getValue();

function getEmails() {
    clearCanvas();
    var label = GmailApp.getUserLabelByName(LabelWithEmails);
    var threads = label.getThreads();

    var row = getFirstRow() + 1;
    var firstmessageId = getfirstmsgid();
    UserProperties.setProperty("firstmsgid", firstmessageId);
    spreadsheet.toast("Loading emails..Please wait. It could take few seconds", "Status", -1);

    var messages = GmailApp.getMessagesForThreads(threads); //gets messages in 2D array

    for (var i = 0; i < 2;/*threads.length;*/ i++) {
        try {
            var messages = threads[i].getMessages();

            for (var m = 0; m < messages.length; m++) {
                var msg = messages[m];
                var isForward = msg.getBody().search(/---------- Forwarded message/i) != -1;

                if(!isValidMessage) continue;

                sheet.getRange(row, 1).setValue(msg.getFrom());
                sheet.getRange(row, 2).setValue(msg.getTo() + ";" + msg.getCc() + ";" + msg.getBcc());
                sheet.getRange(row, 3).setValue(msg.getSubject());
                sheet.getRange(row, 4).setValue(msg.getDate());

                if(!isForward) {
                    // Get only this messages body, ignore the previous chain
                    var body = msg.getBody();
                    var firstIndexOfThread = body.search(/gmail_quote/i); 
                    body = (firstIndexOfThread == -1) ? body : body.substring(0, firstIndexOfThread);

                        sheet.getRange(row, 5).setValue(getTextFromHtml(body));

                } else {
                    // Use the whole body if its a forward
                    sheet.getRange(row, 5).setValue(getTextFromHtml(msg.getBody()));
                    sheet.getRange(row, 6).setValue("***");
                }

            row++;
        }
    } catch (error) {
            Logger.log(error);
        spreadsheet.toast("Error Occured - please see the logs.", "Status", -1);
    }

    if (i == threads.length - 1) {
        spreadsheet.toast("Successfully loaded emails.", "Status", -1);
    }
  }
}

这是一个“垃圾进，垃圾出”的案例。当您在线程视图中使用 gmail 应用程序时，Google 的服务器正在解析电子邮件正文并巧妙地隐藏旧邮件的正文。这使得线程中的最新消息看起来仅包含该消息的新行，并且您有一个较小消息的“链”。

这是一种错觉。线程中的最后一条消息通常首先包含新内容，然后是所有先前消息正文的内容，作为单个消息正文。不同的电子邮件服务和客户端为此使用不同的模式。

您需要能够识别线程中先前消息的内容在当前消息正文中表示的大部分或全部方式，并使用它来仅提取新内容。
