WebRTC：强制对等方使用TURN服务器 [英] WebRTC: force peers to use TURN server

问题描述

我有一个webrtc应用程序，它工作正常，但出于测试目的，我需要测试我的TURN服务器是否工作，但因为两个测试设备都在同一个网络中，我无法测试，想到下面的代码会将候选人限制为只使用TURN服务器的人，

I have a webrtc application, it works fine, but for testing purposes, I need to test if my TURN server works, but because both the testing devices are within the same network, I am unable to test, thought below code would restrict candidates to only the ones using TURN server,

function onIceCandidate(event, targetSessionID, targetUserName) {
    if (event.candidate) {
    var candidate = event.candidate.candidate;
    if(candidate.indexOf("relay")<0){ // if no relay address is found, assuming it means no TURN server
        return;
    }
    sendMessage(candidate); // using socket.io to send to the otherside
...

但我注意到了那个（非常沮丧），这不起作用，因为当同伴创建答案描述时，

but I noticed that( with much frustration), this does not work, because when peer is creating answer description,

....
a=candidate:0 1 UDP 2128609535 13.198.98.221 58779 typ host
a=candidate:0 2 UDP 2128609534 13.198.98.221 58780 typ host
....

这意味着，通信是直接的，而不是通过TURN服务器，我假设这是正确的吗？现在，我如何强制webrtc使用TURN服务器？

this means, the communcation is direct and not through TURN server, am I correct in assuming this? Now, how do I force the webrtc to use the TURN server?

推荐答案

只需添加此项以关闭问题，

just adding this to close the question,

function onIceCandidate(event, targetSessionID, targetUserName) {
    if (event.candidate) {
    var candidate = event.candidate.candidate;
    if(candidate.indexOf("relay")<0){ // if no relay address is found, assuming it means no TURN server
        return;
    }...

以上代码有效，检查到 wireshark ，

The above code works, checked to wireshark,

添加 if（candidate.indexOf（relay）< 0）条件，只能通过TURN服务器进行通信，如果服务器不存在/错误的详细信息，连接状态得到新

after adding the if(candidate.indexOf("relay")<0) condition, communication takes place only through TURN server, if server is not present/ incorrect details, connection state get's struck at new

编辑： iceTransportPolicyrel =nofollow> w3 webrtc ，传递 relay 作为 iceTransportPolicy 应该有效，但我尚未检查它是否已在Firefox和Chrome中实现...

like cullen has said in his answer, according to w3 webrtc, passing relay as iceTransportPolicy should work, but I haven't checked if it is implemented in Firefox and Chrome yet...
