AWS：SNS将SMS消息发送到多个电话号码

Question

From my mobile app, I'd like to send the following message to multiple phone numbers:

"John Doe invited you to a meeting. Download meeting material http://alink.com "

This message will be Transactional

I have a Node.js running on an EC2. I am a mobile app developer and new to AWS.

In my SNS console I created a Topic. This created an ARN: arn:aws:sns:us-east-1:xxx1234xxxx:MyAppName

I have the following code in NodeJS:

var AWS = require('aws-sdk');
var auth = require('../snsAuth');

AWS.config.update = auth

var sns = new AWS.SNS();
var params = {
    Message: "John Doe invited you to a meeting. Download meeting material http://alink.com",
    MessageStructure: 'string',
    PhoneNumber: '1xxx1234',
    Subject: 'MyApp'
};

sns.setSMSAttributes(
    {
        attributes: {
            DefaultSMSType: "Transactional"
        }
    },
    function (error) {
        if (error) {
            console.log(error);
        }
    }
);

sns.publish(params, function (err, data) {
    if (err) console.log(err, err.stack); // an error occurred
    else console.log(data);           // successful response
});

I don't know how to send multiple phone numbers as parameters. Based on the docs, it appears that I need to subscribe to a Topic first and then publish the topic. If those are the right steps, how do I do that in code?

You can use the subscribe API to subscribe a phone number to a topic by sms. But the user has to confirm their subscription to the topic before they will get any published events.

var params = {
  Protocol: 'sms',
  TopicArn: 'arn:aws:sns:us-east-1:xxx1234xxxx:MyAppName',
  Endpoint: '1xxx1234'
};
sns.subscribe(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});
