Can HTML5 Websockets connect 2 clients (browsers) directly without using a server? (P2P)
提问by Justin
Using HTML5 Websockets, can I open a socket directly between 2 clients (browsers) (assuming I know their IP addresses and there are no NAT traversal issues). I want to send some data directly from one browser to another browser, essentially creating a P2P network. Everything I've read so far on the web, websockets are all used to communicate between client and server, but nothing about client to client.
使用 HTML5 Websockets，我可以直接在 2 个客户端（浏览器）之间打开一个套接字（假设我知道他们的 IP 地址并且没有 NAT 遍历问题）。我想将一些数据直接从一个浏览器发送到另一个浏览器，本质上是创建一个 P2P 网络。到目前为止我在网上读到的所有内容，websockets 都用于在客户端和服务器之间进行通信，但与客户端到客户端无关。
Thanks

Update:
更新：
The WebRTCprotocol and API is making rapid progress and allows a Data Channel to be established between two peers (you still may need a STUN/TURN server for the initial NAT traversal and setup).
所述的WebRTC协议和API正在迅速进展，并允许两个对等体（可能仍然需要用于初始NAT遍历和设置一个STUN / TURN服务器）之间建立数据信道。

From past to future: Pick your implementation.
从过去到未来：选择您的实现。
- Most modern browsers support peer to proxy to peer using Websockets.
- Peer to peer is only available using certain browsers plug-ins for example Opera Uniteand FireFox Pow.
- Major browsers are in the process of implementing WebRTCwhich will allow peer to peer.
- 大多数现代浏览器都支持使用Websockets对等代理。
- 点对点只能使用某些浏览器插件，例如Opera Unite和FireFox Pow。
- 主要浏览器正在实施WebRTC，这将允许点对点。

If you just don't want to implement server your self you can use https://httprelay.io. No additional libraries required, all communication based on simple AJAX calls.
如果您只是不想自己实现服务器，则可以使用https://httprelay.io。不需要额外的库，所有通信都基于简单的 AJAX 调用。
