您需要將事件回調(diào)移至加入頻道成功之外?？蛻舳嘶卣{(diào)需要在與客戶端初始化相同的塊內(nèi)發(fā)生。
通過等待 joinChannel 成功，為時(shí)已晚，引擎在添加偵聽器之前就觸發(fā)了該事件。
使用上面的 JS 代碼，它應(yīng)該如下所示：
// rtc object
var rtc = {
client: null,
joined: false,
published: false,
localStream: null,
remoteStreams: [],
params: {}
};
// Options for joining a channel
var option = {
appID: "MY_APP_ID",
channel: "MY_Channel_Name",
uid: null,
token: "Channel_Token"
}
$('#create').click(function() {
// Create a client
rtc.client = AgoraRTC.createClient({
mode: "live",
codec: "h264"
});
// Initialize the client
rtc.client.init(option.appID, function() {
console.log("init success");
// The value of role can be "host" or "audience".
rtc.client.setClientRole("host");
// define callbacks before joining the channel
rtc.client.on("stream-added", function(evt) {
var remoteStream = evt.stream;
var id = remoteStream.getId();
if (id !== rtc.params.uid) {
rtc.client.subscribe(remoteStream, function(err) {
console.log("stream subscribe failed", err);
})
}
console.log('stream-added remote-uid: ', id);
});
rtc.client.on("stream-subscribed", function(evt) {
var remoteStream = evt.stream;
var id = remoteStream.getId();
// Add a view for the remote stream.
addView(id);
// Play the remote stream.
remoteStream.play("remote_video_" + id);
console.log('stream-subscribed remote-uid: ', id);
})
// Join a channel
rtc.client.join(option.token ? option.token : null, option.channel, option.uid ? +option.uid : null, function(uid) {
console.log("join channel: " + option.channel + " success, uid: " + uid);
rtc.params.uid = uid;
// Create a local stream
rtc.localStream = AgoraRTC.createStream({
streamID: rtc.params.uid,
audio: true,
video: true,
screen: false,
})
// Initialize the local stream
rtc.localStream.init(function() {
console.log("init local stream success");
// Publish the local stream
rtc.client.publish(rtc.localStream, function(err) {
console.log("publish failed");
console.error(err);
})
}, function(err) {
console.error("init local stream failed ", err);
})
}, function(err) {
console.error("client join failed", err)
})
}, (err) => {
console.error(err);
});
});
$('#leave').click(function() {
// Leave the channel
rtc.client.leave(function() {
// Stop playing the local stream
rtc.localStream.stop();
// Close the local stream
rtc.localStream.close();
// Stop playing the remote streams and remove the views
while (rtc.remoteStreams.length > 0) {
var stream = rtc.remoteStreams.shift();
var id = stream.getId();
stream.stop();
removeView(id);
}
console.log("client leaves channel success");
}, function(err) {
console.log("channel leave failed");
console.error(err);
})
});
function addView(id, show) {
if (!$("#" + id)[0]) {
$("<div/>", {
id: "remote_video_panel_" + id,
class: "video-view",
}).appendTo("#video");
$("<div/>", {
id: "remote_video_" + id,
class: "video-placeholder",
}).appendTo("#remote_video_panel_" + id);
$("<div/>", {
id: "remote_video_info_" + id,
class: "video-profile " + (show ? "" : "hide"),
}).appendTo("#remote_video_panel_" + id);
$("<div/>", {
id: "video_autoplay_" + id,
class: "autoplay-fallback hide",
}).appendTo("#remote_video_panel_" + id);
}
}
function removeView(id) {
if ($("#remote_video_panel_" + id)[0]) {
$("#remote_video_panel_" + id).remove();
}
}
