視點！B站視頻播放源地址獲取及B站視頻下載

突然之間，我們的B站視頻播放失效了。之前直接使用的ibilibili，發現它的低清版本視頻無法正常加載了。后來加上它的公眾號，才發現，都不容易，十分感謝ibilibili站站長多年的堅持，尤其是聽到他說這個站點每天受到幾千人的攻擊時。ibilibili站提供的高清視頻下載器，下載m4s文件，最后再用ffmpeg轉成mp4。 對于我們而言，視頻的清晰度并不重要，我們需要播放直鏈，僅僅是為了播放和預覽視頻。下載B站視頻本身并不是一個難事，所以下文我將首先介紹如何獲取低清版直鏈，然后談談高清版下載如何是實現。

如果你對這方面有興趣，可以和我們群交流學習，共同進步

之前，通過下面的文章，實現了B站視頻在其他站點的快速預覽和播放。大大地方便了對素材的快速選擇。之前的源地址獲取接口失效后，急需一種新的獲取方式。

1.播放源獲取

通過偽裝移動UA請求網頁，如下

curl "https://m.bilibili.com/video/av70663655.html?from=search" -H "User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1"  --compressed

得到的請求結果中，找到下面這段關鍵信息

就是一個用于播放的鏈接，定位到一個mp4文件。在某些瀏覽器中該文件是沒有辦法播放，是由于reffer檢查，如果要將該鏈接引入到其他站點播放，則需要設置成 no-reffer。

2.高清下載
