推荐答案

我们可以将json消息发送到AWS SNS，以将推送通知发送到应用程序端点.这样我们就可以发送平台(APNS，FCM等)的特定字段和自定义内容.

We can send json message to AWS SNS to send push notification to application endpoint. Which allows us to send platform (APNS, FCM etc) specific fields and customizations.

用于APNS的json消息示例是

Example json message for APNS is,

{
"aps": {
    "alert": {
        "body": "The text of the alert message"
    },
    "badge": 1,
    "sound": "default"
 }
}

这是发送请求的方式，

   var sns = new AWS.SNS();
   var payload = {
      default: 'This is the default message which must be present when publishing a message to a topic. The default message will only be used if a message is not present for 
  one of the notification platforms.',
      APNS: {
        aps: {
          alert: 'The text of the alert message',
          badge: 1,
          sound: 'default'
        }
      }
    };

    // stringify inner json object
    payload.APNS = JSON.stringify(payload.APNS);
    // then stringify the entire message payload
    payload = JSON.stringify(payload);

    sns.publish({
      Message: payload,      // This is Required
      MessageStructure: 'json',
      TargetArn: {{TargetArn}} // This Required
    }, function(err, data) {
      if (err) {
        console.log(err.stack);
        return;
      }
    });
  });

如果您需要支持多个平台，则根据AWS文档，

If you need to support multiple platforms then as per AWS docs,

要将消息发送到在多个平台(例如FCM和APNS)的设备上安装的应用程序，您必须首先将移动终端节点订阅Amazon SNS中的主题，然后将消息发布到 topic .

可以找到 AWS SNS文档可在此处找到将特定于平台的自定义有效负载发送到移动设备

AWS SNS documentation can be found here Send Custom, Platform-Specific Payloads to Mobile Devices
