Android WebRTC无法连接到coTURN服务器：错误401：未经授权

编程问答 2022-06-10

问题描述

我已使用lt-cred-mech选项设置了coTURN服务器（使用TURN REST API）。我生成的用户如下：

  • 用户：1601871288:4e4d54c1-7b69-40a2-b355-ff2b40e003c4
  • 通过：doSnY8s16/vK6ynnALMkbl0DcLo=

我已经通过trickle-ice进行了测试，并且我的浏览器可以连接到我的服务器：

从coTURN服务器登录：

但是当我使用Android应用拨打电话时，应用无法连接。

我的android代码：

PeerConnection.IceServer iceServer = PeerConnection.IceServer
        .builder("turn:x.x.x.x:3478")
        .setUsername("1601871288:4e4d54c1-7b69-40a2-b355-ff2b40e003c4")
        .setPassword("doSnY8s16/vK6ynnALMkbl0DcLo=")
        .setTlsCertPolicy(PeerConnection.TlsCertPolicy.TLS_CERT_POLICY_INSECURE_NO_CHECK)
        .createIceServer();

iceServers.add(iceServer);

PeerConnection.RTCConfiguration rtcConfig = new PeerConnection.RTCConfiguration(iceServers);

// TCP candidates are only useful when connecting to a server that supports
// ICE-TCP.
rtcConfig.tcpCandidatePolicy = PeerConnection.TcpCandidatePolicy.disABLED;
rtcConfig.bundlePolicy = PeerConnection.BundlePolicy.MAXBUNDLE;
rtcConfig.rtcpMuxPolicy = PeerConnection.RtcpMuxPolicy.REQUIRE;
rtcConfig.continualGatheringPolicy = PeerConnection.ContinualGatheringPolicy.GATHER_CONTINUALLY;
rtcConfig.iceTransportsType = PeerConnection.IceTransportsType.ALL;
// Use ECDSA encryption.
 rtcConfig.keyType = PeerConnection.KeyType.ECDSA;

// disable when use loopback
rtcConfig.enableDtlsSrtp = true;
rtcConfig.sdpSemantics = PeerConnection.SdpSemantics.UNIFIED_PLAN;

peerConnection = factory.createPeerConnection(rtcConfig,pcObserver);

但是我从服务器error 401: Unauthorized

收到错误消息

从服务器登录：

241236: session 001000000000000943: realm <> user <>: incoming packet message processed,error 401: Unauthorized
241236: session 001000000000000944: realm <> user <>: incoming packet message processed,error 401: Unauthorized
241236: session 001000000000000943: realm <> user <>: incoming packet message processed,error 401: Unauthorized
241236: session 000000000000000591: realm <> user <>: incoming packet message processed,error 401: Unauthorized

有人可以告诉我我的错误在哪里吗？

谢谢。

解决方法

也许它将帮助您找到一些线索，基本上发生的是您的STUN / TURN服务器未对iceCandidates进行身份验证。 取自RFC docs：

case $age in
  *[!0-9]*) echo "Age must not contain non-numeric digits";;
