Twilio可编程视频和Ionic 3

Question

我正在开发必须实现Twilio可编程视频的移动应用程序。 我已经在Laravel PHP Framework中使用Twilio SDK 5.24.2开发了一个后端，并且运行良好。

在移动应用程序中，我通过npm安装了twilio-video 2.0.0-beta4软件包，并基于“ video-quickstart-js-1.x”中的示例开发了一个页面。问题是当Twilio尝试连接到会议室时，控制台中的错误如下（在日志末尾）：

我在Ionic中的代码如下：

import { Component, ViewChild } from '@angular/core';
import { IonicPage, NavController, NavParams, LoadingController } from 'ionic-angular';
import { ApiServiceProvider } from '../../providers/api-service';
import TwilioVideo from 'twilio-video';

export class VideoPage
{
  public roomSid: string;
  public activeRoom: any;
  public twilioAccessToken: string;

  @ViewChild('remoteMedia') remoteMedia: any;
  @ViewChild('localMedia') localMedia: any;
  @ViewChild('buttonLeave') buttonLeave: any;

  constructor(
    public navCtrl: NavController, 
    public navParams: NavParams,
    private apiServiceProvider: ApiServiceProvider
  ) {
    this.roomSid = navParams.get('room_sid');
    this.joinToRoom(this.roomSid);
  }

  joinToRoom(roomSid: string) {
    let videoCallData = {
      room_sid: roomSid
    };

    this.apiServiceProvider.joinVideoRoom(videoCallData)
    .then(
      (result) => {
        this.twilioAccessToken = result.access_token;
        this.generateVideoCall();
      },
      (error) => {
        console.log(error);
      }
    )
    .catch((error) => {
      console.log(error);
    });
  }

  generateVideoCall() {
    let connectOptions = {
      name: this.roomSid
    };

    connectOptions['logLevel'] = 'debug';

    TwilioVideo.connect(this.twilioAccessToken, connectOptions)
    .then(this.roomJoined, function(error) {
      console.log('Could not connect to Twilio: ' + error.message);
    });
  }

  roomJoined(room: any) {
    this.activeRoom = room;

    // Attach LocalParticipant's Tracks, if not already attached.
    var previewContainer = this.localMedia;
    if (!previewContainer.querySelector('video')) {
      this.attachParticipantTracks(this.activeRoom.localParticipant, previewContainer);
    }

    // Attach the Tracks of the Room's Participants.
    this.activeRoom.participants.forEach(function(participant) {
      console.log("Already in Room: '" + participant.identity + "'");
      let previewContainer = this.remoteMedia;
      this.attachParticipantTracks(participant, previewContainer);
    });

    // When a Participant joins the Room, log the event.
    this.activeRoom.on('participantConnected', function(participant) {
      console.log("Joining: '" + participant.identity + "'");
    });

    // When a Participant adds a Track, attach it to the DOM.
    this.activeRoom.on('trackAdded', function(track, participant) {
      console.log(participant.identity + " added track: " + track.kind);
      var previewContainer = this.remoteMedia;
      this.attachTracks([track], previewContainer);
    });

    // When a Participant removes a Track, detach it from the DOM.
    this.activeRoom.on('trackRemoved', function(track, participant) {
      console.log(participant.identity + " removed track: " + track.kind);
      this.detachTracks([track]);
    });

    // When a Participant leaves the Room, detach its Tracks.
    this.activeRoom.on('participantDisconnected', function(participant) {
      console.log("Participant '" + participant.identity + "' left the room");
      this.detachParticipantTracks(participant);
    });

    // Once the LocalParticipant leaves the room, detach the Tracks of all Participants, including that of the LocalParticipant.
    this.activeRoom.on('disconnected', function() {
      console.log('Left room');

      if (this.previewTracks) {
        this.previewTracks.forEach(function(track) {
          track.stop();
        });
        this.previewTracks = null;
      }

      this.detachParticipantTracks(this.activeRoom.localParticipant);
      this.activeRoom.participants.forEach(this.detachParticipantTracks);
    });
  }

  // Attach the Participant's Tracks to the DOM.
  attachParticipantTracks(participant, container) {
    var tracks = Array.from(participant.tracks.values());
    this.attachTracks(tracks, container);
  }

  // Attach the Tracks to the DOM.
  attachTracks(tracks, container) {
    tracks.forEach(function(track) {
      container.appendChild(track.attach());
    });
  }

  // Detach the Tracks from the DOM.
  detachTracks(tracks) {
    tracks.forEach(function(track) {
      track.detach().forEach(function(detachedElement) {
        detachedElement.remove();
      });
    });
  }

  // Detach the Participant's Tracks from the DOM.
  detachParticipantTracks(participant) {
    var tracks = Array.from(participant.tracks.values());
    this.detachTracks(tracks);
  }

  // Leave Room.
  leaveRoomIfJoined() {
    if (this.activeRoom) {
      this.activeRoom.disconnect();
    }
  }
}

HTML具有下一个结构：

<ion-content padding>
  <div #remoteMedia></div>

  <div #localMedia></div>

  <div id="buttonContainer">
    <button ion-button icon-only round #buttonLeave (click)="leaveCall($event)">
      <ion-icon name="close"></ion-icon>
    </button>
  </div>
</ion-content>

我使用以下代码在设备中运行该应用程序：

ionic cordova run android --device --livereload

如何解决显示的错误？

谢谢！

Answer 1

为避免此错误，执行Ionic应用程序的正确命令是：

ionic cordova run android --device

不得使用--livereload，因为在这种情况下，应用程序访问开发机器的来源不安全。
