如何通过http确认订阅Amazon SNS？我目前正在使用Rails应用程序，希望收到电子邮件退回通知。因此，我尝试浏览Amazon论坛，找到的最接近的是：https://forums.aws.amazon.com/thread.jspa?threadID=87555，它告诉我使用request.raw_post获取请求并进行JSON解析。然而，当我尝试这样做时，它给我一个错误消息，说请求为空。我的方法正确吗？有人能指导我如何从Amazon SNS获取订阅令牌，以便我确认订阅吗？

这对我很有效。在你的控制器中，创建一个类似下面代码的动作。你想要令牌路由，所以你可以在那里看到它。但是我选择了SubscribeURL路由，并且只对URL做一个GET。

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

这是一个适合我的php脚本。（有一些日志行将其写入文件i/tmp/log.txt，这有助于调试正在发生的事情。首先，我从https://sns.us-east-1.amazonaws.com/SimpleNotificationService-f3ecfb7224c7233fe7bb5f59f96de52f.pem下载了amazon cert。请确保也可以在任何地方使用utf8。
对我来说，它只适用于http，当我订阅https url时，我看不到服务器上的任何访问。

使用PHP：

你可以进入file_get_contents('php://input');
你会收到类似于下面的json结构：

{
  "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/..."
}
