javascript - 使用 Amazon SNS 推送通知( Node )

Question

我正在尝试在 Node.js 中使用 Amazon SNS 实现推送通知。我创建了一个主题并使用以下代码发布了一条消息

创建主题

var createTopicPromise = new AWS.SNS({apiVersion: '2010-03-31'}).createTopic({Name: "TOPIC_NAME"}).promise();

// Handle promise's fulfilled/rejected states
createTopicPromise.then(
  function(data) {
    console.log("Topic ARN is " + data.TopicArn);
  }).catch(
    function(err) {
    console.error(err, err.stack);
  });

我有一个 TopicArn 像这样 arn:aws:sns:us-east-1:xxxxxxxxxx:TOPIC_NAME

发布

// Load the AWS SDK for Node.js
var AWS = require('aws-sdk');
// Set region
AWS.config.update({region: 'REGION'});

// Create publish parameters
var params = {
  Message: 'You Got Message!! Hello....', /* required */
  TopicArn: 'arn:aws:sns:us-east-1:xxxxxxxxxx:TOPIC_NAME'
};

// Create promise and SNS service object
var publishTextPromise = new AWS.SNS({apiVersion: '2010-03-31'}).publish(params).promise();

// Handle promise's fulfilled/rejected states
publishTextPromise.then(
  function(data) {
    console.log("Message ${params.Message} send sent to the topic ${params.TopicArn}");
    console.log("MessageID is " + data.MessageId);
  }).catch(
    function(err) {
    console.error(err, err.stack);
  });

现在消息已经发布，我需要在我的手机上看到它。所以我使用了这样的订阅代码

    var params = {
      Protocol: 'application', /* required */
      TopicArn: 'arn:aws:sns:us-east-1:xxxxxxxxxx:TOPIC_NAME', /* required */
      Endpoint: 'MOBILE_ENDPOINT_ARN'
    };

    // Create promise and SNS service object
    var subscribePromise = new AWS.SNS({ apiVersion: '2010-03-31' }).subscribe(params).promise();

    req;
    res;
    // Handle promise's fulfilled/rejected states
    subscribePromise.then(
      function (data) {
        console.log("Subscription ARN is " + data.SubscriptionArn);
      }).catch(
        function (err) {
          console.error(err, err.stack);
        });
  }

我的问题是订阅参数中的 Endpoint 是什么。我应该从哪里得到这个？到目前为止，我是对的吗？请帮帮我。

此处的端点是您需要向 AWS 注册的移动应用程序的 ARN。这是官方文档的片段

For Amazon SNS to send notification messages to mobile endpoints, whether it is direct or with subscriptions to a topic, you first need to register the app with AWS.
