Question

我想使用gmail api发送包含所有html的电子邮件。这是html的预览： https://docs.google.com/drawings/d/1J0nzeTol6VFr8sB1TlMDbTrSVanDncQ8FOelP_SvmY0/edit

但是当我将电子邮件发送到我的测试帐户然后我检查收件箱中的电子邮件时，电子邮件中的所有样式都会丢失。这是发送后电子邮件的屏幕截图。 https://docs.google.com/drawings/d/1yfzmlqzMhJMWbJth-o6mfgSJcGAtUIKr41hpvzlFQGE/edit?usp=sharing

我希望获得电子邮件中的所有样式。我也尝试过charset iso-8859-1，但结果仍然相同。

这是我的PHP代码：

        $service = new Google_Service_Gmail($this->client);
        $user = 'me';
        $strSubject = $subject;
        $strRawMessage = "From: <".$from.">\r\n";
        $strRawMessage .= "To:  <".$to.">\r\n";
        $strRawMessage .= 'Subject: =?utf-8?B?' . base64_encode($strSubject) . "?=\r\n";
        $strRawMessage .= "MIME-Version: 1.0\r\n";
        $strRawMessage .= "Content-Type: text/html; charset=utf-8\r\n";
        $strRawMessage .= 'Content-Transfer-Encoding: quoted-printable' . "\r\n\r\n";
        $strRawMessage .= $message."\r\n";
        // The message needs to be encoded in Base64URL
        $mime = rtrim(strtr(base64_encode($strRawMessage), '+/', '-_'), '=');
        $msg = new Google_Service_Gmail_Message();
        $msg->setRaw($mime);
        //The special value **me** can be used to indicate the authenticated user.
        $service->users_messages->send("me", $msg);

Answer 1

正如OP通过将Content-Transfer-Encoding: quoted-printable更改为Content-Transfer-Encoding: base64所指出的那样解决了问题。

我几乎有同样的问题，能够以同样的方式解决它

Answer 2

解决方案Content-Transfer-Encoding: base64并没有帮助我。电子邮件几乎延迟了，甚至没有收入。而且在70％的情况下-电子邮件正文仍显示为text / plain，而不是text / html。
