无效参数值：重复标头"内容传输编码"

Question

当我试图用电子邮件发送附件时，我收到了这个错误，有人能告诉我我做错了什么吗？这里是我尝试的代码

var payload = `From: 'Amarjeet Singh' <${sender}>
To: ${recipient}
Subject: AWS SES Attachment
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=7f1a313ee430f85a8b054f085ae67abd6ee9c52aa8d056e7f7e19c6e2887
--NextPart
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable
This is the <b>body</b> of the email.
--7f1a313ee430f85a8b054f085ae67abd6ee9c52aa8d056e7f7e19c6e2887
Content-Type: application/json; charset=UTF-8; 
Content-Disposition: attachment; filename="colors.json"
Content-Transfer-Encoding: base64
${file}
--NextPart--`;
var params = {
    RawMessage: {
      Data: payload
    },
    Source: "[e-mail]"
  };

如果你使用的是AWS SES，你的有效负载有两个问题，第一，你的边界不同，第二，请记住换行符，你的字符串模板应该是这样的：

var payload = `From: 'Amarjeet Singh' <${sender}>
To: ${recipient}
Subject: AWS SES Attachment
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=7f1a313ee430f85a8b054f085ae67abd6ee9c52aa8d056e7f7e19c6e2887
