javascript - RTCDataChannel 就绪状态卡在 chrome 中连接但在 Firefox 中工作

Question

我正在尝试实现 RTCDataChannel (webRTC)。

它在 Firefox 中运行良好，但在 chrome 中运行不佳。

Chrome 和 Firefox 都是最新版本。

Chrome 中的 RTCDataChannel 对象:-

RTCDataChannel {
binaryType: "arraybuffer"
bufferedAmount: 0
bufferedAmountLowThreshold: 0
id: 65535
label: "sendDataChannel"
maxRetransmitTime: 65535
maxRetransmits: 65535
negotiated: false
onbufferedamountlow: null
onclose: null
onerror: ƒ (event)
onmessage: ƒ (event)
onopen: ƒ dataChannelStateChanged()
ordered: true
protocol: ""
readyState: "connecting"
reliable: false__proto__:}

Firefox 中的 RTCDataChannel 对象:-

DataChannel { 
binaryType: "blob"
id: 0
label: "sendDataChannel", 
reliable: true, 
readyState: "open",
bufferedAmount: 0, 
bufferedAmountLowThreshold: 0, 
onopen: dataChannelStateChanged(), 
onerror: create_peer_connection/dataChannel.onerror(), 
onclose: null, 
onmessage: create_peer_connection/dataChannel.onmessage(), 
onbufferedamountlow: null 
protocol:""
ordered:true}

我已经浏览了以下链接:-

1. WebRTC data channel stack on readyState "conecting"
2. WebRTC dataChannel.readyState stalling on "connecting"
3. RTCDataChannel's ReadyState is not 'open' .
4. Webrtc Data Channel always in connecting state and not open

请提出 chrome 问题背后的原因是什么？

我能够使用以下帖子解决它:

WebRTC DataChannel: working in Firefox but not Chrome

我不得不改变

pc = new RTCPeerConnection(configuration,
                {optional: [{RtpDataChannels: true}]});

到

pc = new RTCPeerConnection(configuration);
