我试图创建一个与数据通道的webRTC连接(仅限),但当我使用下面提供的代码并运行initCall()
时,数据通道的readyState将堆栈在“connecting”上,并且永远不会更改。我正在使用最新版本的chrome。是什么导致的?
检查信令服务器是否正常工作。
var ottowa = initIO({//Init a connection to the signaling server
onMessage: function(data) { //got message from the signalin server
trace("onMessage with data = " + JSON.stringify(data));
//var signal = JSON.parse(data.toString());
var signal = data;
if(signal.title == "offer")
gotOffer(signal.data);
else if (signal.title == "offerResponse")
gotResponse(signal.data);
},
onCount: function(data) {
}
});
var configuration = {
'iceServers': [{
'url':'stun:stun.l.google.com:19302'
}]
};
joinRoom('demo');//Joins a room in the signaloing server
var pc, channel;
pc = new webkitRTCPeerConnection(configuration, { 'optional': [{'DtlsSrtpKeyAgreement': true}, {'RtpDataChannels': true }] });
channel = pc.createDataChannel("data");
pc.onaddstream = function(obj){
trace("onaddstream");
}
function initCall(){
pc.createOffer(function(offer) {
pc.setLocalDescription(new RTCSessionDescription(offer), function() {
send({//send a message thru the signaling server
title: "offer",
data: offer
});
}, error);
},error);
}
function gotOffer(offer) {
pc.setRemoteDescription(new RTCSessionDescription(offer), function() {
pc.createAnswer(function(answer) {
pc.setLocalDescription(new RTCSessionDescription(answer), function(){
send({//send a message thru the signaling server
title:"offerResponse",
data: answer
});
}, error);
},error);
},error);
}
function gotResponse(offer) {
pc.setRemoteDescription(new RTCSessionDescription(offer), function() {
trace("gotResponse and successfully connected");
},error);
}
channel.onopen = function(event) {
trace("onopen with event = " + event);
}
channel.onmessage = function(event) {
trace("onmessage with event = " + event);
}
function trace(text) {
console.log((performance.now() / 1000).toFixed(3) + ": " + text.toString);
}
function error(err) {
trace("error = " + err);
}
最佳答案
是否有防火墙或其他网络设备可能会阻止连接?连接到信令服务器的工作方式通常与传出连接(客户端到服务器)相同,但RTC将客户端到客户端、传出和传入连接大多数防火墙都会阻止它,所以你可以先检查一下。
