APICloud平台使用融云模块实现音视频通话实践经验总结分享
需求概要:实现视频拨打、接听、挂断、视频界面大小窗口、点击小窗口实现大小窗口互换。
实现思路:一方拨打后,另一方要能收到相应事件,然后接听。接通后,渲染对方视频画面。那么己方视频画面什么时候渲染呢?对于呼叫方,可以在呼叫后开始渲染,也可以接通事件事件发生后再开始渲染。对于接通方可以在点击接听按钮后开始渲染,也可以在接通事件发生后开始渲染。
有了上述思路,在模块文档中查找相应api,编写代码,就可以验证我们的思路是否可以实现。如果遇到问题,再调整实现思路。
以下是融云模块文档链接:https://docs.apicloud.com/Cli...
简要介绍用到的主要API:
**startCall 发起视频通话" title="音视频通话">音视频通话
addCallReceiveListener 音视频来电事件监听
accept 接听来电
addCallSessionListener 音视频通话事件的监听(包含响铃、接通、挂断等多个事件监听)setVideoView 设置视频区域
resetVideoView 重设视频区域
removeVideoView 移除视频区域
hangup 挂断**
下面讲解代码。
要调用音视频通话功能前应先调用 api.hasPermission 接口检查是否有麦克风、相机权限,如果没有,要先申请权限。
api.requestPermission({ list: ['microphone', 'camera', 'storage', 'photos'],
code: 1
})
融云初始化成功之后,可添加相应事件的监听。didReceiveCall 接到来电事件后,弹出接听页面。接听后,会执行到 didConnect 事件, 此时可设置本地窗口 setVideoView ;稍后会执行到remoteUserDidJoin (对端用户加入通话事件),此时可以通过 setVideoView 设置对端用户窗口。通过videoViewBringToFront 接口将本地小窗口调整到最前方。
apiready = function () { rong = api.require('rongCloud2');
rong.init({
huaweiPush: false
}, function (ret, err) {
if (ret.status == 'error') {
api.toast({
msg: err.code
});
} else {
console.log('初始化成功');
rong.setConnectionStatusListener(function (ret, err) {
console.log("连接状态监听:" + ret.result.connectionStatus);
});
//收到来电事件监听
rong.addCallReceiveListener({
target: 'didReceiveCall'
}, function (ret) {
console.log('didReceiveCall:' + JSON.stringify(ret))
callId = ret.callSession.callId;
api.toast({
msg: '来电请接听'
})
fnopenbtnframe(); //打开接听、挂断按钮所在的frame
});
// 通话连接成功监听
rong.addCallSessionListener({
target: 'didConnect'
}, function (ret) {
console.log('didConnect:' + JSON.stringify(ret))
var myname = api.getPrefs({
sync: true,
key: 'myname'
});
//打开本地窗口
fnsetVideoView(api.winWidth - 200, 100, 160, 200, myname);
//将本地窗口显示到最前方
setTimeout(function () {
rong.videoViewBringToFront({
userId: myname
})
}, 1000)
})
//通话已结束的事件
rong.addCallSessionListener({
target: 'didDisconnect'
}, function (ret) {
console.log('didDisconnect:' + JSON.stringify(ret))
})
//对端用户加入了通话的事件
rong.addCallSessionListener({
target: 'remoteUserDidJoin'
}, function (ret) {
console.log("对端用户加入了通话的事件:" + JSON.stringify(ret));
var uid = ret.userId;
//设置远端窗口
fnsetVideoView(0, 0, api.winWidth, api.winHeight, uid);
});
//监听视频区域点击事件,实现大小窗口切换
rong.addVideoViewListener(function (ret) {
//判断点击的是否是初始小窗口
if (ret.userId == myname && meissmall) {
fnresetVideoView(0, 0, api.winWidth, api.winHeight, ret.userId);
fnresetVideoView(api.winWidth - 200, 100, 160, 200, hename);
meissmall = false;
setTimeout(function () {
rong.videoViewBringToFront({
userId: hename
})
}, 1000)
setTimeout(function () {
fnopenbtnframe()
}, 1200)
}
if (ret.userId == hename && !meissmall) {
fnresetVideoView(0, 0, api.winWidth, api.winHeight, ret.userId);
fnresetVideoView(api.winWidth - 200, 100, 160, 200, myname);
meissmall = true;
setTimeout(function () {
rong.videoViewBringToFront({
userId: myname
})
}, 1000)
setTimeout(function () {
fnopenbtnframe()
}, 1200)
}
})
}
});
};
实现效果如下:
其他经验总结:
返回错误码34001,重启loader可解决,可能换账号登录,wifi 同步重启loader 有缓存用户信息导致。
接听不到来电事件,可尝试用4g 网络测试。有些公司防火墙,或者电脑共享的wifi 热点网络有限制或不稳定。
以上经验都是无数次排错总结出来的,看了至少能帮你节省两个工作日。
