2年前作者：+++.分類：Toy博客閱讀(15)違法舉報

這篇具有很好參考價值的文章主要介紹了python爬取bilibili，下載視頻。希望對大家有所幫助。如果存在錯誤或未考慮完全的地方，請大家不吝賜教，您也可以點擊"舉報違法"按鈕提交疑問。

一. 內容簡介

python下載bilibili視頻合集

二. 軟件環(huán)境

2.1vsCode

2.2Anaconda

version: conda 22.9.0

2.3代碼

鏈接：https://pan.baidu.com/s/1WuXTso_iltLlnrLffi1kYQ?pwd=1234

三.主要流程

3.1 下載單個視頻

感覺現在下載的清晰度不夠，可以在找找，給這塊替換了就行

3.6 合集視頻更新

原來會出現部分合集顯示下載成功，但是文件夾里面沒有東西，是因為有些合集名字在命令里面沒辦法執(zhí)行，因為一些特殊符號什么的，所以把合集名字手動指定一下下載就可以了，然后多線程加上去，代碼如下

    # 視頻合計每個視頻接口沒有規(guī)律，然后再播放頁中網頁沒有直接的播放鏈接，所以就用合集頁的鏈接來分析
    # 網頁里面的每個鏈接都是動態(tài)加載的，需要訪問json數據獲取，也或者用虛擬瀏覽器那種等頁面加載完成后訪問(這種以后可能會更新，感覺這個有點麻煩)，
