[英]Configuring Amazon SES Feedback Notifications via Amazon SNS in ASP.NET MVC (C#)
Good day! 美好的一天! I'm just started with Amazon SES.
我刚开始使用Amazon SES。 I want use this in my asp.net mvc (C#) website.
我想在我的asp.net mvc(C#)网站上使用它。
I download and install AWS Toolkit for Visual Studio, create AWS simple console application. 我下载并安装适用于Visual Studio的AWS Toolkit,创建AWS简单控制台应用程序。 So, I have sample code that can send email, using AmazonSimpleEmailService client.
所以,我有使用AmazonSimpleEmailService客户端发送电子邮件的示例代码。
PART 1: 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.");
}
Further, I must configuring Amazon SES Feedback Notifications via Amazon SNS. 此外,我必须通过Amazon SNS配置Amazon SES反馈通知。 I find nice topic with sample code:
我用示例代码找到了很好的主题:
PART 3: http://sesblog.amazon.com/post/TxJE1JNZ6T9JXK/Handling-Bounces-and-Complaints 第3部分: http : //sesblog.amazon.com/post/TxJE1JNZ6T9JXK/Handling-Bounces-and-Complaints
So, I need make PART 2 where I'll get ReceiveMessageResponse response and send it into PART 3. 因此,我需要制作第2部分,我将获得ReceiveMessageResponse响应并将其发送到第3部分。
I need implement in C# this steps: Set up the following AWS components to handle bounce notifications: 我需要在C#中实现这一步骤:设置以下AWS组件来处理退回通知:
1. Create an Amazon SQS queue named ses-bounces-queue.
2. Create an Amazon SNS topic named ses-bounces-topic.
3. Configure the Amazon SNS topic to publish to the SQS queue.
4. Configure Amazon SES to publish bounce notifications using ses-bounces-topic to ses-bounces-queue.
I try write it: 我试着写下来:
// 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);
I'm on the right track? 我走在正确的轨道上?
How I can implement 4 part? 我如何实施4部分? How receive XObject?
如何接收XObject?
Thanks! 谢谢!
You are on the right track - for the missing part 4 you need to implement receiving of a message from the Amazon SQS message queue you created in step 1. See my answer to Example of .net application using Amazon SQS for where to find a respective example - it boils down to the following code: 您正走在正确的轨道上 - 对于缺失的第4部分,您需要实现从步骤1中创建的Amazon SQS消息队列接收消息。请参阅我对使用Amazon SQS的.net应用程序示例的答案,了解各自的位置示例 - 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)
}
}
Within the loop you need to call either ProcessQueuedBounce()
or ProcessQueuedComplaint()
as illustrated in Handling Bounces and Complaints . 在循环中,您需要调用
ProcessQueuedBounce()
或ProcessQueuedComplaint()
如处理退回和投诉中所示 。
I've recently had to tackle this problem and I couldn't find a good code example on how to handle the SNS bounce notification (as well as topic subscription request) from a .Net website. 我最近不得不解决这个问题,我找不到一个关于如何从.Net网站处理SNS退回通知(以及主题订阅请求)的好代码示例。 Here's the Web API method I came up with to handle SNS bounce notifications from Amazon SES.
这是我提出的处理来自Amazon SES的SNS退回通知的Web API方法。
The code is in VB but any online VB to C# converter should be able to easily get it converted for you. 代码在VB中,但任何在线VB到C#转换器都应该能够轻松地为您转换。

I have the same problem today. 我今天也有同样的问题。 I solved the problem by configuring a WebHook (https) in the SNS configuration.
我通过在SNS配置中配置WebHook(https)解决了这个问题。 On the webserver i process now the events.
在网络服务器上,我现在处理事件。 I have create a nuget package with the logic.
我用逻辑创建了一个nuget包。
