Question

我正在使用以下代码中描述的代码：

发送电子邮件。一切正常。现在，我想添加密件抄送（一个或多个），但我不知道如何。

如果我添加：message ['Bcc'] ='mail@mail.com'，它可以工作，但发件人可以看到密件抄送，但我不希望这样。
我知道使用SMTP可以：

    smtp = smtplib.SMTP('smtp.gmail.com', 587)
    smtp.sendmail(user, [to] + bcc, message.as_string())

但是我不想那样做。

如何使用Google google_auth_oauthlib在发件人不知道的情况下添加密件抄送？

这是我正在使用的代码
