Question

如何通过http确认Amazon SNS的订阅？我目前正在为我的应用程序使用Rails，并希望收到有关我的电子邮件退回的通知。所以，我尝试浏览亚马逊论坛，我找到的最接近的是：https://forums.aws.amazon.com/thread.jspa?threadID=87555告诉我使用request.raw_post获取请求，JSON解析它。但是，当我尝试这样做时，它给我一个错误，说请求是空的。我是以正确的方式做到的吗？有人可以指导我如何从Amazon SNS获取订阅令牌，以便我可以确认我的订阅吗？谢谢！：）

Answer 1

这对我有用。在您的控制器中，创建一个类似下面代码的操作。你想要令牌路线，所以你可以在那里看到它。但我选择了SubscribeURL路线，只需在URL上进行GET。

  def sns
     request_json = JSON.parse(request.raw_post, {symbolize_names: true})
     subscribe_url = request_json[:SubscribeURL]
     token = request_json[:Token]
  end

这是一个适用于我的php scrit。（有一些日志行将其写入文件i /tmp/log.txt，这有助于调试正在进行的操作。首先，我从https://sns.us-east-1.amazonaws.com/SimpleNotificationService-f3ecfb7224c7233fe7bb5f59f96de52f.pem下载了亚马逊证书。请务必同时使用utf8

对我来说，它只适用于http。当我订阅https网址时，我在服务器中看不到任何访问权限。

使用PHP：

您可以进入file_get_contents('php://input');

您会收到类似json结构的人

{
  "Type" : "SubscriptionConfirmation",
  "MessageId" : "4..050670318",
  "Token" : "2336412f37fb687f5d51e6e2425f00....",
  "TopicArn" : "arn:aws:sns......",
  "Message" : "You have chosen to subscribe to the topic arn:aws:sns:us-east-1:430......\nTo confirm the subscription, visit the SubscribeURL included in this message.",
  "SubscribeURL" : "https://sns.us-east-1.amazonaws.com/?Action=ConfirmSubscription&TopicArn=arn:aws:sns:us-....&Token=2336412f37fb687f5d51e6e2425f004aef17b3ebbd98e122....",
  "Timestamp" : "2020-06-30T14:31:43.953Z",
  "SignatureVersion" : "1",
  "Signature" : "i3zpoQ3mAbcxTr18m/z5PL9Ls...",
  "SigningCertURL" : "https://sns.us-east-1.amazonaws.com/..."
}
