未在libjingle_peerconnection库中添加TURN服务器

Question

我使用libjingle_peerconnection库进行WebRTC连接，

这是rtc连接的初始化，我在同一网络中工作， 不适用于其他网络

我需要做什么才能使转弯服务器正常工作？

func initalizeWebRTC() -> Void {

    RTCPeerConnectionFactory.initializeSSL()
    self.webRtcClient  = RTCPeerConnectionFactory.init()
    let stunServer = self.defaultStunServer()
    let turnServer = self.getTurn()
    let defaultConstraint = self.createDefaultConstraint()
    let array = [turnServer, stunServer]
    print(array)
    self.peerConnection = self.webRtcClient?.peerConnection(withICEServers: array, constraints: defaultConstraint, delegate: self)
    print(peerConnection)

    self.localVideoView.delegate = self
    self.remoteVideoView.delegate = self
    // webrtc initalized local rendering of video on
    self.addLocalMediaStrem()

}

func defaultStunServer() -> RTCICEServer {
    let url = URL.init(string: "stun:stun.l.google.com:19302");
    let iceServer = RTCICEServer.init(uri: url, username: "", password: "")
    return iceServer!
}

func getTurn() -> RTCICEServer {
    let url = URL.init(string: "turn:xxx.xxx.xx.xxx:xxxx");
    let iceServer = RTCICEServer.init(uri: url, username: "xxxx", password: "xxxxxxxxxxxx")
    return iceServer!
}
