是“长轮询”创建Web实时应用程序的最有效方法？ [英] Is "long polling" the most efficient way to create a Web Real Time App?

问题描述

我想创建一个这样的应用程序：

创建这个实时应用程序的最有效方法是什么？

闪光？长期投票？ HTTP流媒体？或者别的什么东西？

谢谢;） 现在，长时间的投票可能是最好的解决方案。许多大牌网站都有长时间的投票实施，包括Facebook，Google和eBay。并非每个人都在其浏览器中安装/启用了Flash。将来 Web Sockets 可能能够为我们做一个更容易的工作。

更新：在撰写本文时，。还有Opera的可供下载的公共快照构建与API的实现。这意味着测试API是广泛可用的。有关详情，请参阅此答案。

What is the most efficient way to create this real time application?

Flash? Long polling? Http Streaming? or something else?

Thanks ;)

解决方案

For now, long polling is probably the best solution. Many big-name sites have long polling implementations, including Facebook, Google and eBay. Not everyone has Flash installed/enabled in their browsers. In the future Web Sockets might be able to do an easier job of it for us.

Update: As of this writing, the WebSocket API is implemented in the latest WebKit (Chrome/Safari) and Firefox 4 beta. There is also a public snapshot build of Opera available for download with an implementation of the API. This means testing the API is widely available. For more information, see this answer.
