Question

我收到了一封电子邮件：

Dear xxx,

Thank you. You have just ordered the ultimate treat for your taste buds.

Your yummy, lip smacking delight is being prepared with utmost love and attention at your own neighbouring Pizza Hut – Bengaluru - Airport Road....

但是当我说“show original”时，它显示为：

Gmail客户端如何解码此混淆文本中的内容？此外，这是一个特定于Gmail API的qn：这是Gmail API在返回内容时会为我解码的内容吗？

Answer 1

邮件是base64编码的。在浏览器中按F12打开开发人员工具，然后对消息进行base64解码

这将为您提供原始邮件。

Answer 2

这是base64编码。任何SMTP（简单邮件传输协议）MIME对象都包含以下格式：

MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=frontier

This is a message with multiple parts in MIME format.
--frontier
Content-Type: text/plain

This is the body of the message.
--frontier
Content-Type: application/octet-stream
Content-Transfer-Encoding: base64

PGh0bWw+CiAgPGhlYWQ+CiAgPC9oZWFkPgogIDxib2R5PgogICAgPHA+VGhpcyBpcyB0aGUg
Ym9keSBvZiB0aGUgbWVzc2FnZS48L3A+CiAgPC9ib2R5Pgo8L2h0bWw+Cg==
--frontier--

正文（在您的情况下是邮件内容）始终是base64编码的。如果您想阅读，Wiki链接会更多地与您联系。

http://en.wikipedia.org/wiki/MIME

解码只需使用任何base64解码库（在javascript中）来读取内容。（
