我试图弄清楚如何使用AWS .NET SDK来确认订阅SNS主题.
订阅是通过HTTP进行的
端点将位于.net mvc网站中.
我在任何地方找不到任何.net示例？
一个工作的例子太棒了.
我正在尝试这样的事情
Dim snsclient As New Amazon.SimpleNotificationService.AmazonSimpleNotificationServiceClient(ConfigurationSettings.AppSettings("AWSAccessKey"),ConfigurationSettings.AppSettings("AWSSecretKey"))
Dim TopicArn As String = "arn:aws:sns:us-east-1:991924819628:post-delivery"
If Request.Headers("x-amz-sns-message-type") = "SubscriptionConfirmation" Then
Request.InputStream.Seek(0,0)
Dim reader As New System.IO.StreamReader(Request.InputStream)
Dim inputString As String = reader.ReadToEnd()
Dim jsSerializer As New System.Web.Script.Serialization.JavaScriptSerializer
Dim message As Dictionary(Of String,String) = jsSerializer.Deserialize(Of Dictionary(Of String,String))(inputString)
snsclient.ConfirmSubscription(New Amazon.SimpleNotificationService.Model.ConfirmSubscriptionRequest With {.AuthenticateOnUnsubscribe = False,.Token = message("Token"),.TopicArn = TopicArn})
End If
解决方法
以下是使用MVC WebApi 2和最新AWS .NET SDK的工作示例.
var jsonData = Request.Content.ReadAsStringAsync().Result;
var snsMessage = Amazon.SimpleNotificationService.Util.Message.ParseMessage(jsonData);
//verify the signaure using AWS method
if(!snsMessage.IsMessageSignatureValid())
throw new Exception("Invalid signature");
if(snsMessage.Type == Amazon.SimpleNotificationService.Util.Message.MESSAGE_TYPE_SUBSCRIPTION_CONFIRMATION)
{
var subscribeUrl = snsMessage.SubscribeURL;
var webClient = new WebClient();
webClient.DownloadString(subscribeUrl);
return "Successfully subscribed to: " + subscribeUrl;
}
