无法使用Agora Web SDK NG在移动数据上发布RTC客户端

分类：编程问答

如何解决无法使用Agora Web SDK NG在移动数据上发布RTC客户端

我是WebRTC和Websockets的新手。我尝试使用Agora Web SDK NG进行一对一的视频通话，并且在同一网络上的两个设备（一台PC和一个Android移动设备）都能正常工作。将智能手机用于移动数据后，尽管它仍然可以同时在连接到路由器的PC上运行，但我无法再加入呼叫了。

这是我的函数，用于在Angular服务中启动呼叫：

async startCall(userId: string) {
    this.callStatus$.next('connecting');
    this.rtc.client = AgoraRTC.createClient({ mode: "rtc",codec: "vp8" });

    // * Listen to new users joining the channel
    this.rtc.client.on('user-published',async (user,mediaType) => {
      console.log('remote user published');
      // Subscribe to a remote user.
      await this.rtc.client.subscribe(user,mediaType);
      console.log('subscribe to remote user success');
      this.callStatus$.next('online');

      // If the subscribed track is video.
      if (mediaType === 'video') {
        // Get `RemoteVideoTrack` in the `user` object.
        const remoteVideoTrack = user.videoTrack;

        // Play the remote video track.
        // Pass the DIV container and the SDK dynamically creates a player in the container for playing the remote video track.
        // remoteVideoTrack.play(playerContainer);

        // Or just pass the ID of the DIV container.
        remoteVideoTrack.play('video-player');
      }

      // If the subscribed track is audio.
      if (mediaType === 'audio') {
        // Get `RemoteAudioTrack` in the `user` object.
        const remoteAudioTrack = user.audioTrack;
        // Play the audio track. No need to pass any DOM element.
        remoteAudioTrack.play();
      }
    });

    // * Listening for users leaving the channel
    this.rtc.client.on('user-unpublished',user => {
      console.log('remote user unpublished');
      this.callStatus$.next('waiting');
    });

    this.rtc.client.on('exception',(event) => console.error('RTC CLIENT ERROR ',event));

    // * Joining the channel
    try {
      // Join channel
      await this.rtc.client.join(agoraConfig.appId,agoraConfig.channel,agoraConfig.token,userId);
      // Create an audio track from the audio sampled by a microphone.
      this.rtc.localAudioTrack = await AgoraRTC.createMicrophoneAudioTrack();
      // Create a video track from the video captured by a camera.
      this.rtc.localVideoTrack = await AgoraRTC.createCameraVideoTrack({ facingMode: 'user' });
      // Publish the local audio and video tracks to the channel.
      // ---------------- THE STATEMENT BELOW IS WHERE IT HANGS ---------------------
      await this.rtc.client.publish([this.rtc.localAudioTrack,this.rtc.localVideoTrack]);
      // ----------------------------------------------------------------------------

      // If peer already connected set status to online otherwise set as waiting
      if (this.rtc.client.remoteUsers.length)
        this.callStatus$.next('online');
      else
        this.callStatus$.next('waiting');

      console.log('self join and publish success !');
    } catch (e) {
      this.callStatus$.error('join-error');
      console.error(e);
    }
  }

它会产生各种错误，并会继续尝试在上面带有注释的语句上重新发布流。以下是导航到该页面然后尝试从我的移动设备加入通话的Web控制台日志：

如您所见，它在Client.publish timeout和receive p2p lost之后的pub p2p gateway lost处发布失败。然后，它会无限期地重试start reconnect pc。

什么可能导致此行为？

如果需要提供有关此问题的更多信息，请告诉我。

解决方法

可以按照Agora Error FAQs中所述的不同方式解决p2p错误。
