使用Amazon SES添加列表-取消订阅标头

Question

我正在寻找一个工作的C#示例，以添加列表-取消订阅标题与亚马逊SES。

在读到Amazon-SES现在支持添加头之后，我搜索了一个C#示例，但是找不到。

Answer 1

我找不到nice API like they have for Java。对于C#，我找到了两个替代方案。

最简单的选择可能是切换到SMTP接口和.Net的原生SMTP类(或第三方库)：Send an Email Using SMTP with C#

示例代码使用来自System.Net.Mail的MailMessage class

// Create and build a new MailMessage object
MailMessage message = new MailMessage();
message.IsBodyHtml = true;
message.From = new MailAddress(FROM,FROMNAME);
message.To.Add(new MailAddress(TO));
message.Subject = SUBJECT;
message.Body = BODY;
// Comment or delete the next line if you are not using a configuration set
message.Headers.Add("X-SES-CONFIGURATION-SET", CONFIGSET);

另一个(不太吸引人的)选择是使用SendRawEmailRequest。使用此API，您必须在MemoryStream中对消息及其标头、附件和其他数据进行编码。

示例代码，来自AWS SDK .Net documentation - SES - RawMessage

var sesClient = new AmazonSimpleEmailServiceClient();

var stream = new MemoryStream(
  Encoding.UTF8.GetBytes("From: johndoe@example.com\n" +
    "To: janedoe@example.com\n" +
    "Subject: You're invited to the meeting\n" +
    "Content-Type: text/plain\n\n" +
    "Please join us Monday at 7:00 PM.")
);

var raw = new RawMessage
{
  Data = stream
};

var to = new List<string>() { "janedoe@example.com" };
var from = "johndoe@example.com";

var request = new SendRawEmailRequest
{
  Destinations = to,
  RawMessage = raw,
  Source = from
};

sesClient.SendRawEmail(request);
