使用Google Apps Script发送邮件时出现异常换行问题

嘿，我看到你在使用Google Apps Script发送邮件时遇到了正文换行位置异常的问题，咱们来快速搞定它～

问题根源 #

你当前用\n/\n\n来实现换行，但Google Apps Script的MailApp.sendEmail()默认发送的是HTML格式邮件。在HTML语法里，普通的换行符\n不会被解析成换行，只会被当作空格处理，这就是导致换行位置不对的核心原因。

两种解决方案 #

方案1：改用HTML换行标签（推荐）

如果希望邮件保留HTML格式（方便后续添加样式），把\n替换成HTML的换行标签<br>，空两行就用<br><br>。修改后的代码示例：

function sendEmail(){ 
  var name = "MyName";
  var body = name + " has issued a challenge. You already have a match currently scheduled so you have the option to decline. Reply to this email with the word 'ACCEPT' or 'DECLINE' in the subject." + "<br><br>NOTE: If you do not respond to this email you will automatically accept the challenge and be responsible for scheduling the match...";
  
  // 发送邮件时指定htmlBody参数
  MailApp.sendEmail({
    to: "recipient@example.com", // 替换成实际收件人邮箱
    subject: "Challenge Notification",
    htmlBody: body
  });
}

方案2：强制发送纯文本邮件

如果不需要HTML格式，直接设置邮件的MIME类型为纯文本，这样\n就能正常生效。代码示例：

function sendEmail(){ 
  var name = "MyName";
  var body = name + " has issued a challenge. You already have a match currently scheduled so you have the option to decline. Reply to this email with the word 'ACCEPT' or 'DECLINE' in the subject." + "\n\nNOTE: If you do not respond to this email you will automatically accept the challenge and be responsible for scheduling the match...";
  
  MailApp.sendEmail({
    to: "recipient@example.com", // 替换成实际收件人邮箱
    subject: "Challenge Notification",
    body: body,
    mimeType: MimeType.PLAIN_TEXT
  });
}

小提醒 #

• 记得给变量声明加上分号（虽然GAS允许省略，但规范写法能避免潜在问题）
• 你的代码里body内容好像没写完，记得补全完整的文本哦～
