1.上傳視頻之前根據(jù)自己需要對所上傳的視頻進行加密設置

下面說一下對于加密視頻的H5播放 重點就在創(chuàng)建playsafe--獲取token

1. 頁面播放器加載

<div id="player"></div> <script src="//player.polyv.net/script/player.js"></script> <script>var player = polyvPlayer({wrap: '#player',width: 800,height: 533,vid: '7d9f485283907d3f2cf12a866910b682_7', playsafe: function(vid, next) { //不是加密視頻playsafe不需要$.ajax({type: 'post',url: '服務端用來獲取token的url',data: {vid: vid},}).done(function (res) {var result = JSON.parse(res);playsafe = result.data.token;next(playsafe);});}}); </script>

2. Token 獲取（服務端來獲取）

　　(1)?獲取客戶端IP

　　(2)?創(chuàng)建加密生成sign所需參數(shù)

　　(3)?將參數(shù) userid、 videoid、 ts、 viewerip、 viewerid、 viewername、 extraparams 按照ASCII升序 key + value + ... + key + value拼接成字符串

　　(4)?將拼接好的字符串首尾拼接secretkey

　　(5)?將拼接好的字符串通過MD5加密 取大寫MD5（32位）

　　(6)?post請求polyv 獲取token

c#代碼如下：

?

public string GetPolyToken(string vid){var userId = "7d9f485283"; // polyv 提供的服務器間的通訊驗證var secret = "1NM4HdSS9P"; // polyv 提供的接口調(diào)用簽名訪問的keyvar ip = "112.53.65.101"; // 客戶端真實ipvar timeStamp = Convert.ToInt64((DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, 0)).TotalMilliseconds).ToString(); // 毫秒級時間戳（13位）var viewerId = "12345"; //觀看者idvar viewerName = "12345"; //用戶昵稱（中文需要urlencode('張三')）var extraParam = "HTML5"; //自定義參數(shù)// 1. 創(chuàng)建加密生成 sign 的所需參數(shù)Dictionary<string, string> parameters = new Dictionary<string, string>{{"userId", userId},{"videoId", vid},{"ts", timeStamp},{"viewerIp", ip},{"viewerId", viewerId},{"viewerName", viewerName},{"extraParams", extraParam}};// 2.將參數(shù) userid、 videoid、 ts、 viewerip、 viewerid、 viewername、 extraparams 按照ASCII升序 key + value + ... + key + value 拼接成字符串 ascDicStrvar ascDic = parameters.OrderBy(o => o.Key).ToDictionary(o => o.Key, p => p.Value.ToString());var ascDicStr = "";foreach (var kv in ascDic){ascDicStr += kv.Key + kv.Value;}// 3. 首尾拼接 secretkeyvar signStr = secret + ascDicStr + secret;// 4. 取大寫MD5（32位） eg：DFC38BAACA122385A055D99739834A6Dvar sign1 = MD5(signStr);var sign = sign1.Replace("-", "");// 5. 將生成的 sign 作為參數(shù)一并傳給polyv用來獲取tokenparameters.Add("sign",sign);string serviceUrl = "https://hls.videocc.net/service/v1/token";//模擬 post 請求HttpWebRequest request = null;HttpWebResponse response = null;Stream reqStream = null;request = (HttpWebRequest)WebRequest.Create(serviceUrl);request.Method = "post"; //設置為post請求request.ReadWriteTimeout = 5000;request.KeepAlive = false;request.ContentType = "application/x-www-form-urlencoded;charset=utf-8";byte[] postData = Encoding.UTF8.GetBytes(BuildQuery(parameters, "utf8")); //使用utf-8格式組裝post參數(shù)reqStream = request.GetRequestStream();reqStream.Write(postData, 0, postData.Length);response = (HttpWebResponse)request.GetResponse();Stream responseStream = response.GetResponseStream();StreamReader streamReader = new StreamReader(responseStream, Encoding.GetEncoding("gb2312"));string retString = streamReader.ReadToEnd();streamReader.Close();responseStream.Close();return retString;}//組裝請求參數(shù)private string BuildQuery(IDictionary<string, string> parameters, string encode){StringBuilder postData = new StringBuilder();bool hasParam = false;IEnumerator<KeyValuePair<string, string>> dem = parameters.GetEnumerator();while (dem.MoveNext()){string name = dem.Current.Key;string value = dem.Current.Value;// 忽略參數(shù)名或參數(shù)值為空的參數(shù)if (!string.IsNullOrEmpty(name)){if (hasParam){postData.Append("&");}postData.Append(name);postData.Append("=");if (encode == "gb2312"){postData.Append(HttpUtility.UrlEncode(value, Encoding.GetEncoding("gb2312")));}else if (encode == "utf8"){postData.Append(HttpUtility.UrlEncode(value, Encoding.UTF8));}else{postData.Append(value);}hasParam = true;}}return postData.ToString();}/// <summary>/// MD5 hash加密/// </summary>/// <param name="s"></param>/// <returns></returns>public static string MD5(string s){var md5 = new System.Security.Cryptography.MD5CryptoServiceProvider();var result = BitConverter.ToString(md5.ComputeHash(UnicodeEncoding.UTF8.GetBytes(s.Trim())));return result;}
