如何查看AppRTC使用的iceServers

如何查看AppRTC使用的iceServers

WebRTC的demo（AppRTC）提供测试网站/，它返回的参数是这样的：

var loadingParams = {errorMessages: [],isLoopback: false,warningMessages: [],mediaConstraints: {"audio": true, "video": {"optional": [{"minWidth": "1280"}, {"minHeight": "720"}], "mandatory": {}}},offerOptions: {},peerConnectionConfig: {"rtcpMuxPolicy": "require", "bundlePolicy": "max-bundle", "iceServers": []},peerConnectionConstraints: {"optional": []},iceServerRequestUrl: '=AIzaSyA2WoxRAjLTwrD7upuk9N2qdlcOch3D2wU',iceServerTransports: '',wssUrl: 'wss://apprtc-ws.webrtc:443/ws',wssPostUrl: ':443',bypassJoinConfirmation: false,versionInfo: {"gitHash": "7341b731567cfcda05079363fb27de88c22059cf", "branch": "master", "time": "Mon Sep 23 10:45:26 2019 +0200"},};

使用POST方式查看AppRTC的iceServers如下：

root@monica:~# curl -d "key=AIzaSyA2WoxRAjLTwrD7upuk9N2qdlcOch3D2wU"  --referer /
{"lifetimeDuration": "86400s","iceServers": [{"urls": ["stun:64.233.188.127:19302","stun:[2404:6800:4008:c06::7f]:19302"]},{"urls": ["turn:64.233.188.127:19305?transport=udp","turn:[2404:6800:4008:c06::7f]:19305?transport=udp","turn:64.233.188.127:19305?transport=tcp","turn:[2404:6800:4008:c06::7f]:19305?transport=tcp"],"username": "CLmyo/MFEgYo3mLt4vIYzc/s6OMTIICjBQ","credential": "iqHMgEtiki1Mh7hFI4yaKJHLrz4=","maxRateKbps": "8000"}],"blockStatus": "NOT_BLOCKED","iceTransportPolicy": "all"
}

这里要注意：查看所使用的http请求方式，只能POST不能GET，此外还要带上referer才行。
