我在 Python 中使用 Django 频道的后端。在其中，我有一个选择在线用户并将数据发送给另一个用户的方法。

但是当我要建立连接时，出现了一些错误和不稳定的情况。有时它可以完美运行并建立连接，有时会出现错误。

似乎“ICE Candidate”的发送随机进入了所有内容的前面，导致错误。有时它仅在响应后调用。

这个初始序列在我的 Javascript 中的 WebRTC 中是否正确？（OnIceCandidate 一直在拍摄）

function getUserMediaSuccess(stream) {
    window.localStream = localStream = stream;
    localVideo.srcObject = stream;
    // localVideo.src = window.URL.createObjectURL(stream);

    var iceServers = {
        'iceServers': [
            {'urls': 'stun:stun.services.mozilla.com'},
            {'urls': 'stun:stun.l.google.com:19302'},
        ]
    };


    //creating our RTCPeerConnection object

    peerConnection = new RTCPeerConnection(iceServers);
    console.log("RTCPeerConnection object was created");
    console.log(peerConnection);


    peerConnection.addStream(localStream);

    if ('ontrack' in peerConnection) {
        // WebRTC Spec, Firefox
        peerConnection.ontrack = function (event) {
          remoteVideo.srcObject = event.streams[0];
         };
     } else {
        // Chrome, etc. This can be removed once all browsers support `ontrack`
        peerConnection.onaddstream = function (event) {
          // remoteVideo.src = window.URL.createObjectURL(event.stream);
          remoteVideo.srcObject = event.stream;
        };
     }

    //setup ice handling
    //when the browser finds an ice candidate we send it to another peer
    peerConnection.onicecandidate = function (event) {

       if (event.candidate) {
          send("candidate", {candidate: event.candidate});
       }
    };

    peerConnection.ondatachannel = function(event) {
       var receiveChannel = event.channel;
       receiveChannel.onmessage = function(event) {
          console.log("ondatachannel message:", event.data);
       };
    };
    openDataChannel();
}
