首先我們要會引入TRTC Web SDK

demo中的index.html中說的很明確,哪些是第三方庫,哪些是腳本
先看一下index.html的代碼:

里面有:輸入用戶ID、房間號的輸入框;還有進入房間、離開房間、開始推流、停止推流按鈕
下面來看看邏輯代碼index.js:

/* eslint-disable require-jsdoc */ // initialize userId/roomId $('#userId').val('user_' + parseInt(Math.random() * 100000000)); $('#roomId').val('889988'); let rtc = null; $('#join').on('click', function(e) { e.preventDefault(); console.log('join'); if (rtc) return; const userId = $('#userId').val(); const roomId = $('#roomId').val(); const config = genTestUserSig(userId); rtc = new RtcClient({ userId, roomId, sdkAppId: config.sdkAppId, userSig: config.userSig }); rtc.join(); }); $('#publish').on('click', function(e) { e.preventDefault(); console.log('publish'); if (!rtc) { Toast.error('請先加入房間!'); return; } rtc.publish(); }); $('#unpublish').on('click', function(e) { e.preventDefault(); console.log('unpublish'); if (!rtc) { Toast.error('請先加入房間!'); return; } rtc.unpublish(); }); $('#leave').on('click', function(e) { e.preventDefault(); console.log('leave'); if (!rtc) { Toast.error('請先加入房間!'); return; } rtc.leave(); rtc = null; }); $('#settings').on('click', function(e) { e.preventDefault(); $('#settings').toggleClass('btn-raised'); $('#setting-collapse').collapse(); });
可以看出。先讓給用戶ID和房間號設置了值,
點擊進入房間按鈕的代碼:
$('#join').on('click', function(e) { e.preventDefault(); console.log('join'); if (rtc) return; const userId = $('#userId').val(); const roomId = $('#roomId').val(); const config = genTestUserSig(userId);//根據userId生成一個對象含:sdkAppId、userSig,具體代碼見GenerateTestUserSig.js rtc = new RtcClient({//創建一個rtc實例 傳入userid、房間號、sdkAppId、userSig userId, roomId, sdkAppId: config.sdkAppId, userSig: config.userSig,//簽名 }); rtc.join();//調用join方法 });
GenerateTestUserSig.js:根據SDKAPPID, SECRETKEY(秘鑰), EXPIRETIME(簽名過期時間 默認設置7天不要太短)生成:userSig(簽名)

/* eslint-disable require-jsdoc */ /* * Module: GenerateTestUserSig * * Function: 用於生成測試用的 UserSig,UserSig 是騰訊雲為其雲服務設計的一種安全保護簽名。 * 其計算方法是對 SDKAppID、UserID 和 EXPIRETIME 進行加密,加密算法為 HMAC-SHA256。 * * Attention: 請不要將如下代碼發布到您的線上正式版本的 App 中,原因如下: * * 本文件中的代碼雖然能夠正確計算出 UserSig,但僅適合快速調通 SDK 的基本功能,不適合線上產品, * 這是因為客戶端代碼中的 SECRETKEY 很容易被反編譯逆向破解,尤其是 Web 端的代碼被破解的難度幾乎為零。 * 一旦您的密鑰泄露,攻擊者就可以計算出正確的 UserSig 來盜用您的騰訊雲流量。 * * 正確的做法是將 UserSig 的計算代碼和加密密鑰放在您的業務服務器上,然后由 App 按需向您的服務器獲取實時算出的 UserSig。 * 由於破解服務器的成本要高於破解客戶端 App,所以服務器計算的方案能夠更好地保護您的加密密鑰。 * * Reference:https://cloud.tencent.com/document/product/647/17275#Server */ function genTestUserSig(userID) { /** * 騰訊雲 SDKAppId,需要替換為您自己賬號下的 SDKAppId。 * * 進入騰訊雲實時音視頻[控制台](https://console.cloud.tencent.com/rav ) 創建應用,即可看到 SDKAppId, * 它是騰訊雲用於區分客戶的唯一標識。 */ const SDKAPPID = 1400324973; /** * 簽名過期時間,建議不要設置的過短 * <p> * 時間單位:秒 * 默認時間:7 x 24 x 60 x 60 = 604800 = 7 天 */ const EXPIRETIME = 604800; /** * 計算簽名用的加密密鑰,獲取步驟如下: * * step1. 進入騰訊雲實時音視頻[控制台](https://console.cloud.tencent.com/rav ),如果還沒有應用就創建一個, * step2. 單擊“應用配置”進入基礎配置頁面,並進一步找到“帳號體系集成”部分。 * step3. 點擊“查看密鑰”按鈕,就可以看到計算 UserSig 使用的加密的密鑰了,請將其拷貝並復制到如下的變量中 * * 注意:該方案僅適用於調試Demo,正式上線前請將 UserSig 計算代碼和密鑰遷移到您的后台服務器上,以避免加密密鑰泄露導致的流量盜用。 * 文檔:https://cloud.tencent.com/document/product/647/17275#Server */ const SECRETKEY = 'aaa3e88fffd77e4f3755a423151ea4008a4539aa64d41c0d16c3e1a844e2f3f5'; // a soft reminder to guide developer to configure sdkAppId/secretKey if (SDKAPPID === '' || SECRETKEY === '') { alert( '請先配置好您的賬號信息: SDKAPPID 及 SECRETKEY ' + '\r\n\r\nPlease configure your SDKAPPID/SECRETKEY in js/debug/GenerateTestUserSig.js' ); } const generator = new LibGenerateTestUserSig(SDKAPPID, SECRETKEY, EXPIRETIME); const userSig = generator.genTestUserSig(userID); return { sdkAppId: SDKAPPID, userSig: userSig }; }
我們還發現加入房間的代碼里 new RtcClient();這樣一個代碼,字面意思是創建一個rtc實例對象;
下面來看看rtc-client.js中的代碼:

看到這里,我在本地寫了demo,有個報錯,先到這里,推薦大家看文檔:
文檔地址:https://cloud.tencent.com/document/product/647/16863
可以現充基礎音視頻通話來做,慢慢的我那個下看文檔
也可以看一下最佳實踐里的小例子,很簡短,可以照着實現一個web端的音視頻通話;
文檔地址:https://cloud.tencent.com/document/product/647/32225
下面是基於demo中的一些js文件自己實現的一個實時音視頻的,進入房間、退出房間、開始推流、停止推流的小例子,就提的代碼還沒研究;先貼上代碼:

效果:
。
