html – 电子邮件标记 – Gmail修改标记以添加额外的字符串“3D

%script{ type: "application/ld+json" }
  {
  "@context" : "http://schema.org","@type" : "FoodEstablishmentReservation","reservationNumber" : "#{reservation.id}",...
  }

我还将电子邮件的发件人和收件人修改为与here中提到的相同的电子邮件ID,以便在开发模式下测试架构.

当我在Gmail收件箱中收到电子邮件时,我发现之前没有任何不同之处.当我查看电子邮件的原始消息时,它显示：

Return-Path: <breezebhoewal@gmail.com>
...
Date: Wed,21 Dec 2016 13:14:45 +0530
From: breezebhoewal@gmail.com
To: breezebhoewal@gmail.com
...
Mime-Version: 1.0
Content-Type: multipart/alternative; boundary="--==_mimepart_585a32ecf2d94_143673fd10d24128893014"; charset=UTF-8
Content-Transfer-Encoding: 7bit

----==_mimepart_585a32ecf2d94_143673fd10d24128893014
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
...
<script type=3D'application/ld+json'>
  {
  "@context" : "http://schema.org","reservationNumber" : "<reservation-id>",...
  }
</script>
...

现在,如果我验证了这个< script>标签内容在Email markup tester中,它说“没有结构化数据”,但只要我从< script>中删除“3D”标记并使其成为< script type ='application / ld json'>,它为所有字段正确提取结构化数据.

所以,我无法弄清楚为什么这个额外的字符串“3D”被添加到HTML？是因为哈姆尔？还是Gmail呢？是否有任何我可以修复在开发环境中测试此电子邮件标记.如果需要更多信息,请与我们联系.
