Google脚本：从文档生成电子邮件会丢失格式

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Google脚本：从文档生成电子邮件会丢失格式相关的知识，希望对你有一定的参考价值。
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）。然后我的公司使用脚本从工作表中提取名称，并向每个人发送一封电子邮件。
但是，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。超链接工作，所以我敢肯定它尊重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使用包含粗体文本的脚本制作了电子邮件。
示例文档（工具>脚本编辑器>运行以将其草稿放入草稿文件夹。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,
});
}
答案
Per Sandy Good的建议是，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 = /.cd{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="(cd{1,} ){0,}(cd{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Docs导入电子邮件的功能），但它有效。
