Websocket and cross-domain
提问by
Currently, I am developing two webapps :
目前，我正在开发两个 webapps ：
- the core, developed in Java with Vert.x, receives data from a lot of other apps and sends it to client)
- the client, developed in PHP/JS, display data from the core.
- 核心，使用 Vert.x 用 Java 开发，从许多其他应用程序接收数据并将其发送到客户端）
- 用 PHP/JS 开发的客户端显示核心数据。
The client isn't on the same domain as my core for the production phase.
在生产阶段，客户端与我的核心不在同一个域中。
Since my development period, the two webapps are hosted in the same computer. I used "ws:\\localhost:9090" to connect my client to my core and I had no problem to transfer data.
在我的开发期间，这两个 webapp 托管在同一台计算机上。我使用“ws:\\localhost:9090”将我的客户端连接到我的核心，并且传输数据没有问题。
But, today, I try to replace localhost with my IP Address and, it didn't work :s
但是，今天，我尝试用我的 IP 地址替换 localhost，但它不起作用：s
I think that it's because the client isn't in the same domain as the core. But I don't know how I can correct this problem ?
我认为这是因为客户端与核心不在同一个域中。但我不知道如何解决这个问题？
Do you have any idea ?
你有什么主意吗 ？
Thanks !
谢谢 ！

Yes, Websocket can do cross-domain, but you will need to have a handshake in order to get this going. You might want to take a look at: http://en.wikipedia.org/wiki/WebSocketsfor an example of a handshake.
是的，Websocket 可以跨域，但你需要握手才能实现这一点。您可能需要查看：http: //en.wikipedia.org/wiki/WebSockets以获取握手示例。
