以芒果TV播放頁(yè)地址http://www.mgtv.com/v/10/167938/c/2942052.html?為例回溺，說(shuō)說(shuō)如何解析得到真實(shí)視頻地址。

提取視頻ID（即vid）

芒果TV的視頻ID可以從播放頁(yè)地址中得到抡谐。上述播放頁(yè)地址中铁追，2942052就是視頻ID.

請(qǐng)求接口

以視頻ID為參數(shù)請(qǐng)求接口 http://v.api.mgtv.com/player/video?retry=1&video_id=2942052 返回的JSON數(shù)據(jù)如下：

我們可以看到姻成，stream列表里面共有3個(gè)清晰度也祠，stream_domain列表里面共有3個(gè)域名昙楚。假如選擇超清清晰度對(duì)應(yīng)的url，然后在url前面加上3個(gè)域名中的任一個(gè)诈嘿，構(gòu)成一個(gè)地址 http://disp.titan.mgtv.com/vod.do?fmt=2&pno=1000&fid=593B5886239791678A15C4A872A60B08&now=1478094895&gsid=79b4eb17ce3b441084b4828230fdfdd7&file=%2Fmp4%2F2016%2Fxinwen%2Fwjxw_46493%2F593B5886239791678A15C4A872A60B08_20160106_1_1_1100_mp4%2FE2017FFD796C00BB185FBC30B6D7360B.m3u8

那些不以#號(hào)開(kāi)頭的行就是視頻分段地址的一部分淳梦。只不過(guò)，完整的視頻分段地址需要構(gòu)造出來(lái)昔字。如何構(gòu)造呢爆袍？我們用瀏覽器開(kāi)發(fā)者工具觀(guān)察到最終的視頻地址是這樣的：

這兩個(gè)地址的前面一部分是一樣的，有木有李滴？這下該知道如何構(gòu)造完整的視頻分段地址了吧螃宙。
