我正在尝试通过AWS Simple Email Service发送附件,我可以让它发送没有ATTACHMENTS的原始电子邮件,但是当我尝试使用附件时,它总是会失败。我是否正确构建了我的MIME邮件?
好的,这里是正确发送的MIME:
From: test@example.com
To: test@example.com
Subject: Test Email
Content-Type: multipart/mixed;
boundary="_003_97DCB304C5294779BEBCFC8357FCC4D2"
MIME-Version: 1.0
--_003_97DCB304C5294779BEBCFC8357FCC4D2
Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: quoted-printable
Hello, This is a test email.
当我附上附件时发送失败:
From: test@example.com
To: test@example.com
Subject: Test Email
Content-Type: multipart/mixed;
boundary="_003_97DCB304C5294779BEBCFC8357FCC4D2"
MIME-Version: 1.0
--_003_97DCB304C5294779BEBCFC8357FCC4D2
Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: quoted-printable
Hello, This is a test email.
--_003_97DCB304C5294779BEBCFC8357FCC4D2
Content-Type: text/txt; name="test.txt"
Content-Description: test.txt
Content-Disposition: attachment; filename="test.txt";
Content-Transfer-Encoding: base64
VGhpcyBpcyBhIHRlc3QgYXR0YWNobWVudC4=
--_003_97DCB304C5294779BEBCFC8357FCC4D2
有什么明显的错误吗?
我通过base64对整个消息进行编码并将其添加到此URL的末尾来构建调用:
Action=SendRawEmail&Destinations.member.1=test%40example.com&RawMessage.Data={base64 encoded MIME Message}
解答:
MIME文件存在两个问题。首先
尾随boundery不应该在那里,因为它显然正在寻找MIME消息的另一个方面,例如另一个附件。
定义为“text / txt”的Content-Type实际上应该是“text / plain”
因此,对于这两个更改的含义,您可以获得以下有效的MIME消息:
From: test@example.com
To: test@example.com
Subject: Test Email
Content-Type: multipart/mixed;
boundary="_003_97DCB304C5294779BEBCFC8357FCC4D2"
MIME-Version: 1.0
--_003_97DCB304C5294779BEBCFC8357FCC4D2
Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: quoted-printable
