WebRTC的信令通道

Question

我想创建自己的视频聊天应用程序。我使用WebRTC框架。我阅读了一些教程，每个主题都假设信令通道存在。如何实现自己的信令渠道？

Answer 1

Since signalling is not defined for the WebRTC standard at the moment, it leaves you a few options. Check out this article for more info the following articles:

• Signalling Options for WebRTC Applications
• Choosing your signalling protocol

1.SIP over WebSockets

Companies like JSSIP offer a SIP signalling framework over Javascript. The advantage here is that it's interoperable with the usual VoIP structures.

• JSSIP
• SIPJS
• SIPML5

2.The WebRTC Data Channel

Uncharted territory but viable!

• Tutorial by Pusher

3.XMPP

If you take this route, it is probably either because you have an existing XMPP installation

• Jingle

4.JSON over COMET or WebSockets

My favourite! WebRTC signalling shouldn't be done any other way than the Web way.

• Matrix
• Firebase

I hope this helps!

Answer 2

您可以创建Node.js WebSocket服务器或其他WebSocket服务器来代理连接。 Here是一个简单的指南，可以让第一个客户端与服务器通信。另一种选择是PeerJS，它可以处理信令并减轻设置WebRTC呼叫的大部分复杂性。

Answer 3

有了可用的无服务器选项，原始的HTTP AJAX选项可能就可伸缩性和成本而言不错。

使用JSON创建普通的HTTP API交换信息。
