Question

我正在处理简单的项目，并且遇到了问题。我想从"div player_data="得到字符串。下面是这个div：

<div id="mediaplayer60597053" 
    player_data='{ 
     "id": "mediaplayer60597053", 
     "ads": { 
     "schedule": [{ 
      "enabled": true, 
      "counter": false, 
      "skip": true, 
      "click": true, 
      "key": "", 
      "tag": "https:\/\/www.cda.pl\/xml.php?type=g_embed&get=pool&ts=1500453286", 
      "repeat": 1, 
      "time": 0, 
      "type": "pool", 
      "displayAs": "prerol" 
     }] 
     }, 
     "video": { 
     "id": "60597053", 
     "file": "http:\/\/vrbx072.cda.pl\/dYXEHM8Nw3y_TZTmTs4e0g\/1500496486\/vl9afb2190473cc908d0c33cdb15bb212994083ca30c797154058bc8717c4ca746.mp4", 
     "manifest": null, 
     "duration": "6115", 
     "durationFull": "01:41:55", 
     "poster": "\/\/static.cda.pl\/v001\/img\/mobile\/poster16x9.png", 
     "type": "plain", 
     "width": 1920, 
     "height": 816, 
     "content_rating": null, 
     "quality": "vl", 
     "ts": 1500453286, 
     "hash": "26be0bc36e8575c32ff32f4329a301889d1f6f7a" 
     }, 
     "nextVideo": null, 
     "autoplay": false, 
     "seekTo": 0, 
     "premium": false, 
     "api": { 
     "client": "json_client", 
     "ts": "1500453286_60686", 
     "key": "9a3859a86e909430bd379badfa68d0d712603626", 
     "method": "" 
     }, 
     "user": { 
     "role": "guest" 
     } 
    }' 
    tabindex="1"> 
</div> 

我想这个字符串：

"http:\/\/vrbx072.cda.pl\/dYXEHM8Nw3y_TZTmTs4e0g\/1500496486\/vl9afb2190473cc908d0c33cdb15bb212994083ca30c797154058bc8717c4ca746.mp4 

感谢您的帮助。

看起来你需要你得到div，然后从那里提取json对象。您可以使用soup.find来提取div，然后使用json.loads将json字符串转换为python字典。

import json 

div = soup.find('div', {'id' : 'mediaplayer60597053' }) 
data = json.loads(div['player_data']) 

print(data['video']['file']) 
# 'http://vrbx072.cda.pl/dYXEHM8Nw3y_TZTmTs4e0g/1500496486/vl9afb2190473cc908d0c33cdb15bb212994083ca30c797154058bc8717c4ca746.mp4'
