Is it possible to receive an Amazon SNS message on a JS script?
提问by tvdias
I know some options using ruby on rails and/or node.js and PubNuB, a service that has many APIs so you can send/receive notifications between (almost) any platform.
我知道一些使用 ruby on rails 和/或 node.js 和 PubNuB 的选项，该服务具有许多 API，因此您可以在（几乎）任何平台之间发送/接收通知。
I now how to send messages from PHP and how to receive them there using Amazon SNS, but how can I receive a push notification (a SNS message) on a JS/jQuery script?
我现在如何从 PHP 发送消息以及如何使用 Amazon SNS 在那里接收它们，但是如何在 JS/jQuery 脚本上接收推送通知（SNS 消息）？

Yes, but not directly and you'll have to poll for messages on a timer...
是的，但不是直接的，你必须在计时器上轮询消息......
In the Product Details pageunder the heading "Flexible", you'll see that none of the currently supported formats/transports can be hosted in the browser.
在“灵活”标题下的“产品详细信息”页面中，您将看到当前支持的格式/传输均无法在浏览器中托管。
However... Amazon SQSis one of the supported transports, and it in turn can be accessed from JavaScript - see an example app here: http://aws.amazon.com/code/Amazon-SQS/1254. (The example shows JavaScript accessing SQS).
但是…… Amazon SQS是受支持的传输方式之一，反过来可以从 JavaScript 访问它 - 请在此处查看示例应用程序：http: //aws.amazon.com/code/Amazon-SQS/1254。（该示例显示了 JavaScript 访问 SQS）。
You'd have to manually poll though, as there is no "push" to the browser with SQS.
不过，您必须手动轮询，因为使用 SQS 没有“推送”到浏览器。
(Alternatively, you could do it all server-side, and then you could use potentially use websockets to push the messages to the browser.)
（或者，您可以在服务器端完成所有操作，然后您可以使用潜在的 websockets 将消息推送到浏览器。）

Use a service worker in your project and set up a Push Notification handler... I created a GCM project and made a little node.js server and it seems to receive messages from SNS... No polling required.
在您的项目中使用 Service Worker 并设置推送通知处理程序...我创建了一个 GCM 项目并制作了一个小 node.js 服务器，它似乎从 SNS 接收消息...不需要轮询。
