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/Client-API/Open-SDK/rongCloud2
简要介绍用到的主要API:
-startCall 发起音视频通话
-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。
