我正在查看这个站点，它应该是测试 TURN 服务器的表（根据这个这个答案）。

plugin.temasys.com.sg/demo/samples/web/content/peerconnection/trickle-ice/index.html

我输入了我的服务器信息，但找不到任何东西来确定服务器是否正常工作。即使没有选择服务器，ice 候选部分看起来也一样。

我的 TURN 服务器安装在 Amazon EC2 上。我在这里按照 coturn 存储库中的安装说明进行操作：

github.com/coturn/coturn/blob/master/INSTALL

以下是我在执行命令启动 TURN 服务器时在服务器中得到的内容，从这里开始：

RFC 3489/5389/5766/5780/6062/6156 STUN/TURN Server

Max number of open files/sockets allowed for this process: 4096
0:
Due to the open files/sockets limitation,
max supported number of TURN Sessions possible is: 2000 (approximately)

它似乎正在工作，但我怎么知道？我为我的无知道歉，我已经阅读了很多关于这方面的文档，我无法跟踪所有内容。

编辑：嗯，事情正在发生:)

每当使用上述网站时，我现在都会在我的回合服务器上收到这些：

64: session 000000000000000004: realm <realm> user <ubuntu>: incoming packet message processed, error 401: Unauthorised

编辑 2：我删除了 ubuntu 部分，现在收到似乎是成功的响应。仍然不知道这意味着什么，但这是一个开始:)

如果你有一个带有 WebRTC 的测试应用程序。

您可以在 Firefox 上强制开启。

标签：about:config

搜索：media.peerconnection.ice.relay_only

将其设置为true

目前 Firefox 只使用 TURN 中继。

编辑： github.io 中的一个很好的实现从评论到另一个答案（在 IceTransports 值中选择“中继”）：

Test TURN Server

在您的浏览器控制台（firefox 或 chrome）中运行以下代码，替换127.0.0.1为您的 aws 的外部 IP，这应该会给您答案：

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   //compatibility for firefox and chrome
      , pc = new myPeerConnection({iceServers:[turnConfig]})
      , noop = function(){};
    pc.createDataChannel("");    //create a bogus data channel
    pc.createOffer(function(sdp){
      if(sdp.sdp.indexOf('typ relay') > -1){ // sometimes sdp contains the ice candidates...
        promiseResolved = true;
        resolve(true);
      }
      pc.setLocalDescription(sdp, noop, noop);
    }, noop);    // create offer and set local description
    pc.onicecandidate = function(ice){  //listen for candidate events
      if(promiseResolved || !ice || !ice.candidate || !ice.candidate.candidate || !(ice.candidate.candidate.indexOf('typ relay')>-1))  return;
      promiseResolved = true;
      resolve(true);
    };
  });   
}

checkTURNServer({
    url: 'turn:127.0.0.1',
    username: 'test',
    credential: 'test'
}).then(function(bool){
    console.log('is my TURN server active? ', bool? 'yes':'no');
}).catch(console.error.bind(console));

PS：确保两件事，在启动 TURN 服务器时将 aws 的外部 ip 作为参数的一部分传递，确保您使用的端口在 aws 设置中为接收和发送打开。
