保利威視頻播放
首先上線播放視頻容易出的問題就是下載，以及盜錄的問題，保利威視提供的API能夠幫助我們解決這個問題~
解決下載的問題就是通過加密視頻的形式，解決盜錄是通過跑馬燈的形式來實現的，那么我們來看下文檔~到底要怎么做
注冊賬號，上傳視頻等
注冊一個保利威的賬號得到user_id以及secretKey
網站上還有上傳以及視頻設置等功能~~
加密以及跑馬燈功能的實現
注意: 一定要仔細閱讀文檔~~特別是下面PHP代碼的例子~~類比着實現~~
個人認為保利威文檔寫的不太清晰~一定要細心~~~~
播放加密視頻的流程
1--播放加密視頻需要在保利威視頻播放器里加一個playsafe的參數
2--playsafe參數的值是token 也可以是一個function 這個function有兩個參數
一個是vid 一個是next 這個next方法必須被執行~ next(token) 而且要把token當做參數
3-- 那這個token到底是什么呢？
這個token需要我們像保利威的接口發POST請求獲取~
接口地址是 https://hls.videocc.net/service/v1/token ~文檔中有~
發送POST請求帶的參數是文檔要求的~
如果攜帶的參數對~這個接口會給我們返回驗證通過的token~
我們把token放入播放器的playsafe就可以播放了~~
播放跑馬燈視頻
播放跑馬燈視頻要求先必須用新的播放器~也就是引入新的js~
還有要在視頻設置里配置一個回調的url~~
1--使用新的播放器去播放視頻的時候，如果視頻是授權跑馬燈的，
保利威會默認向你提供的回調接口發送GET請求~
2-- GET請求會攜帶一些參數，需要我們這個接口返回文檔要求的信息~~
3-- 按照文檔的實例來編寫接口~成功后就可以播放視頻~並且攜帶跑馬燈~

特別注意:
不能用Response 只能用HttpResponse
以及代碼中哪些字符串加密成sign
