Question

我正在尝试从Google文档生成电子邮件。我们的想法是在Doc中保留一个预制的响应;随着Doc的更新，预制响应也是如此（而不是在脚本中对其进行硬编码）。然后我的公司使用该脚本从工作表中提取名称并向他们发送每封电子邮件。

截至上周，格式化不会复制。例如，如果Google文档中有粗体文本，则会将文本复制到草稿中，但不会加粗。当我将HTML直接从Doc复制到Gmail时，我唯一能想到的是Gmail不尊重CSS。超链接有效，所以我确信它尊重html。

如果问题是它不尊重css，我的替代方案是什么？此外，我确信这在上周工作，因为我在我的发件箱中发了一封电子邮件，我用这个包含粗体文本的脚本。

示例文档（工具＆gt;脚本编辑器＆gt;运行将草稿放入您的草稿文件夹。您必须登录Gmail并授予其权限）：

https://docs.google.com/document/d/15Y4lGHq-gsftz6JEzpvql57ZOBTe9CWgk0x29OW0onc/edit

脚本代码：

var docId="15Y4lGHq-gsftz6JEzpvql57ZOBTe9CWgk0x29OW0onc";

function makeNewEmail(){
  var subject="Test Email";
  var forDriveScope = DriveApp.getStorageUsed(); //needed to get Drive Scope requested
  var url = "https://docs.google.com/feeds/download/documents/export/Export?id="+docId+"&exportFormat=html";
  var param = {
    method      : "get",
    headers     : {"Authorization": "Bearer " + ScriptApp.getOAuthToken()},
    muteHttpExceptions:true,
  };
  var html = UrlFetchApp.fetch(url,param).getContentText();

  GmailApp.createDraft(Session.getActiveUser().getEmail(), subject, "HTML is not enabled in your email client. Sad face!", {
    htmlBody: html,
  });  
}

Per Sandy Good的建议，我能够通过让脚本将内部样式表移动到内联来格式化电子邮件。

请注意，它目前只处理.c标记（没有h标记）并假设head不以.c标记开头。

var docId="1VnidBWgxxn1-287yo6Qf8CjKOlQhX-9qF1mIaWugTK4";
var classArray=[];

function makeNewEmail(){
  //get html from Doc
  var subject="Test Email";
  var forDriveScope = DriveApp.getStorageUsed(); //needed to get Drive Scope requested
  var url = "https://docs.google.com/feeds/download/documents/export/Export?id="+docId+"&exportFormat=html";
  var param = {
    method      : "get",
    headers     : {"Authorization": "Bearer " + ScriptApp.getOAuthToken()},
    muteHttpExceptions:true,
  };
  var html = UrlFetchApp.fetch(url,param).getContentText();

  //docs uses css in the head, but gmail only takes it inline. need to move css inline.
  //DOES NOT HANDLE HEADER CLASSES (eg h1, h2).
  var headEnd = html.indexOf("</head>");
  //get everything between <head> and </head>, remove quotes
  var head = html.substring(html.indexOf("<head>")+6,headEnd).replace(/"/g,"");
  //split on .c# with any positive integer amount of #s
  var regex = /\.c\d{1,}/;
  var classes = head.split(regex);
  //get class info and put in an array index by class num. EG c4{size:small} will put "size:small" in classArray[4]
  var totalLength = 0;
  for(var i = 1; i < classes.length; i++){
    //assume the first string (classes[0]) isn't a class definition
    totalLength = totalLength + classes[i-1].length;
    var cNum = head.substring(totalLength+2,head.indexOf("{",totalLength)); //totallength+2 chops off .c, so get what's between .c and {
    totalLength = totalLength + 2 + cNum.length //add .c and the number of digits in the num
    classArray[cNum] = classes[i].substring(1,classes[i].indexOf("}")); //put what's between .c#{ and } in classArray[#]
  }

  //now we have the class definitions, let's put it in the html  
  html = html.substring(headEnd+7,html.indexOf("</html>")); //get everything between <html> and </html>
  var classMatch = /class=\"(c\d{1,} ){0,}(c\d{1,})\"/g
  //matches class="c# c#..." where c#[space] occurs any number of times, even zero times, and c#[no space] occurs after it, exactly once
  html = html.replace(classMatch,replacer); //replace class="c# c#..." with the definitions in classArray[#]

  //make the e-mail!
  GmailApp.createDraft(Session.getActiveUser().getEmail(), subject, "HTML is not enabled in your email client. Sad face!", {
    htmlBody: html,
  });
}

function replacer(match){
  var csOnly = match.substring(7,match.length-1); //class=" has 7 chars, remove the last "
  var cs = csOnly.split(" "); //get each c#
  var ret = "style=\""
  for(var cCount = 0; cCount < cs.length; cCount++){
    ret = ret + classArray[cs[cCount].substring(1)];
  }
  return ret+"\"";
}

这显然有点烦人（理想情况下，Gmail会（1）允许内部样式表或（2）提供从文档导入电子邮件的功能），但它可以正常工作。
