使用webRTC时
有时需要自己搭建turn服务器
如何测试搭建好的turn服务器是否可用
下面给出代码
修改checkTURNServer里面对象的
url/username/credential分别对应url/用户名/密码

function checkTURNServer(turnConfig, timeout){
return new Promise(function(resolve, reject){
setTimeout(function(){
if(promiseResolved) return;
resolve(false);
promiseResolved = true;
}, timeout || 5000);
var promiseResolved = false,
myPeerConnection = window.RTCPeerConnection || window.mozRTCPeerConnection || window.webkitRTCPeerConnection, // 兼容firefox和chrome
pc = new myPeerConnection({iceServers:[turnConfig]}),
noop = function(){};
pc.createDataChannel(""); // 创建一个伪数据通道
pc.createOffer(function(sdp) {
if(sdp.sdp.indexOf('typ relay') > -1){ // 有时sdp包含ice候选项…
promiseResolved = true;
resolve(true);
}
pc.setLocalDescription(sdp, noop, noop);
}, noop); // 创建报价并设置本地描述
pc.onicecandidate = function(ice){ // 监听候选事件
if(promiseResolved || !ice || !ice.candidate || !ice.candidate.candidate || !(ice.candidate.candidate.indexOf('typ relay')>-1)) return;
promiseResolved = true;
resolve(true);
};
});
}
checkTURNServer({
url: 'turn:53.83.181.100:3478',
username: '1232131311:abc',
credential: 'sfffqwerfwef3243524fx='
}).then(function(bool){
console.log('is my TURN server active? ', bool? 'yes':'no');
}).catch(console.error.bind(console));
