C# 在ASP.NET MVC（C）中通过Amazon SNS配置Amazon SES反馈通知

你好！ 我刚开始学习亚马逊SES。 我想在我的asp.NETMVC网站中使用它

我下载并安装用于VisualStudio的AWS工具包，创建AWS简单控制台应用程序。 所以，我有可以使用AmazonSimpleEmailService客户端发送电子邮件的示例代码

第1部分：

using (AmazonSimpleEmailService client = AWSClientFactory.CreateAmazonSimpleEmailServiceClient(RegionEndpoint.USEast1))
{
     var sendRequest = new SendEmailRequest
     {
     Source = senderAddress,
     Destination = new Destination { ToAddresses = new List<string> { receiverAddress } },
     Message = new Message
     {
        Subject = new Content("Sample Mail using SES"),
        Body = new Body { Text = new Content("Sample message content.") }
     }
     };

     Console.WriteLine("Sending email using AWS SES...");
     SendEmailResponse response = client.SendEmail(sendRequest);
     Console.WriteLine("The email was sent successfully.");
 }

我试着写：

// 1. Create an Amazon SQS queue named ses-bounces-queue.
 AmazonSQS sqs = AWSClientFactory.CreateAmazonSQSClient(RegionEndpoint.USWest2);
                    CreateQueueRequest sqsRequest = new CreateQueueRequest();
                    sqsRequest.QueueName = "ses-bounces-queue";
                    CreateQueueResponse createQueueResponse = sqs.CreateQueue(sqsRequest);
                    String myQueueUrl;
                    myQueueUrl = createQueueResponse.CreateQueueResult.QueueUrl;
// 2. Create an Amazon SNS topic named ses-bounces-topic
AmazonSimpleNotificationService sns = new AmazonSimpleNotificationServiceClient(RegionEndpoint.USWest2);
                    string topicArn = sns.CreateTopic(new CreateTopicRequest
                    {
                        Name = "ses-bounces-topic"
                    }).CreateTopicResult.TopicArn;
// 3. Configure the Amazon SNS topic to publish to the SQS queue
                    sns.Subscribe(new SubscribeRequest
                    {
                        TopicArn = topicArn,
                        Protocol = "https",
                        Endpoint = "ses-bounces-queue"
                    });
// 4. Configure Amazon SES to publish bounce notifications using ses-bounces-topic to ses-bounces-queue
                    clientSES.SetIdentityNotificationTopic(XObject);

我在正确的轨道上

如何实现第4部分？如何接收XObject

谢谢

您走在正确的轨道上-对于缺少的第4部分，您需要实现从步骤1中创建的消息队列接收消息。请参阅我的答案，以了解在何处可以找到相应的示例-它归结为以下代码：

// receive a message
ReceiveMessageRequest receiveMessageRequest = new ReceiveMessageRequest();
receiveMessageRequest.QueueUrl = myQueueUrl;
ReceiveMessageResponse receiveMessageResponse = sqs.
   ReceiveMessage(receiveMessageRequest);
if (receiveMessageResponse.IsSetReceiveMessageResult())
{
    Console.WriteLine("Printing received message.\n");
    ReceiveMessageResult receiveMessageResult = receiveMessageResponse.
        ReceiveMessageResult;
    foreach (Message message in receiveMessageResult.Message)
    {
        // process the message (see below)
    }
}

---

在循环中，您需要调用ProcessQueuedBounce或ProcessQueuedCompaint，如中所示。

我最近不得不解决这个问题，但我找不到一个好的代码示例来说明如何处理SNS跳出通知以及.Net网站的主题订阅请求。下面是我提出的处理来自AmazonSES的SNS跳出通知的WebAPI方法

该代码是在VB中，但任何在线应该能够很容易地得到它为您转换

我今天也有同样的问题。我通过在SNS配置中配置WebHook https解决了这个问题。我现在在Web服务器上处理事件。我已经用这个逻辑创建了一个nuget包

我的密码-

[路线识别] [HttpPost] 公共异步任务seNotificationAsync { var body=string.Empty； 使用var reader=new StreamReaderRequest.Body { body=wait reader.ReadToEndAsync； } var notificationProcessor=新notificationProcessor； var result=等待notificationProcessor.ProcessNotificationAsyncbody； //您的处理逻辑。。。 返回StatusCodeStatusCodes.Status200OK； }

非常感谢。但是我实现了在没有SQS的情况下接收SNS通知。我希望这在没有SQS的情况下能起作用。嗨，我写了SES的博客文章。如果您使用HTTP/S端点而不是SQS，则反弹和投诉处理将正常工作。然而，SNS因互联网问题而受到质疑。我在示例代码中使用了SQS，因为SNS到SQS的交付具有明显更高的可靠性，而反弹和投诉处理通常被认为是一项关键操作。
