我使用Twilio Javascript sdk和php实现了twilio视频通话功能。如果我在github上的快速入门教程中使用旧的sdk和代码,一切都运行正常。(虽然它不支持IOS)。当我使用最新的sdk时,我收到错误,功能不再有用。
在index.html文件中使用的旧Twilio Javascript sdk
<script src="//media.twiliocdn.com/sdk/js/video/releases/1.0.0-beta2/twilio-video.js"></script>
使用的新Twilio Javascript sdk:
<script src="//media.twiliocdn.com/sdk/js/video/v1/twilio-video.min.js"></script>
我的index.js
文件。
var videoClient;
var activeRoom;
var previewMedia;
var identity;
var roomName;
// Check for WebRTC
if (!navigator.webkitGetUserMedia && !navigator.mozGetUserMedia) {
alert('WebRTC is not available in your browser.');
}
// When we are about to transition away from this page, disconnect
// from the room, if joined.
window.addEventListener('beforeunload', leaveRoomIfJoined);
$(document).ready(function() {
console.log('testing');
$.getJSON('./token.php', function (data) {
identity = data.identity;
console.log(data);
// Create a Video Client and connect to Twilio
videoClient = new Twilio.Video.Client(data.token);
document.getElementById('room-controls').style.display = 'block';
// Bind button to join room
document.getElementById('button-join').onclick = function () {
roomName = document.getElementById('room-name').value;
if (roomName) {
log("Joining room '" + roomName + "'...");
videoClient.connect({ to: roomName}).then(roomJoined,
function(error) {
log('Could not connect to Twilio: ' + error.message);
});
} else {
alert('Please enter a room name.');
}
};
// Bind button to leave room
document.getElementById('button-leave').onclick = function () {
log('Leaving room...');
activeRoom.disconnect();
};
});
});
// Successfully connected!
function roomJoined(room) {
activeRoom = room;
log("Joined as '" + identity + "'");
document.getElementById('button-join').style.display = 'none';
document.getElementById('button-leave').style.display = 'inline';
// Draw local video, if not already previewing
if (!previewMedia) {
room.localParticipant.media.attach('#local-media');
}
room.participants.forEach(function(participant) {
log("Already in Room: '" + participant.identity + "'");
participant.media.attach('#remote-media');
});
// When a participant joins, draw their video on screen
room.on('participantConnected', function (participant) {
log("Joining: '" + participant.identity + "'");
participant.media.attach('#remote-media');
});
// When a participant disconnects, note in log
room.on('participantDisconnected', function (participant) {
log("Participant '" + participant.identity + "' left the room");
participant.media.detach();
});
// When we are disconnected, stop capturing local video
// Also remove media for all remote participants
room.on('disconnected', function () {
log('Left');
room.localParticipant.media.detach();
room.participants.forEach(function(participant) {
participant.media.detach();
});
activeRoom = null;
document.getElementById('button-join').style.display = 'inline';
document.getElementById('button-leave').style.display = 'none';
});
}
// Local video preview
document.getElementById('button-preview').onclick = function () {
if (!previewMedia) {
previewMedia = new Twilio.Video.LocalMedia();
Twilio.Video.getUserMedia().then(
function (mediaStream) {
previewMedia.addStream(mediaStream);
previewMedia.attach('#local-media');
},
function (error) {
console.error('Unable to access local media', error);
log('Unable to access Camera and Microphone');
});
};
};
// Activity log
function log(message) {
var logDiv = document.getElementById('log');
logDiv.innerHTML += '<p>> ' + message + '</p>';
logDiv.scrollTop = logDiv.scrollHeight;
}
function leaveRoomIfJoined() {
if (activeRoom) {
activeRoom.disconnect();
}
}
他们github中的代码(使用quickstart示例作为参考)最近更改了,他们使用的是express.js,因此我不确定它出错的地方。有人可以帮我解决这个问题吗?
答案 0 :(得分:1)
Twilio开发者传道者在这里。
在测试版和发布版之间,我们改变了初始化库的方式。您不再使用构造函数,这就是您看到错误的原因。
相反,你应该使用Twilio.Video.connect(token, { name: 'room-name' })
,它会返回一个你加入房间后解决的承诺。
查看latest Twilio Video JS documentation以获取完整的代码示例,并查看如何使用版本1 SDK。
让我知道这是否有帮助。
