Question

我正在尝试生成[url_audioenci，url_caratula，titulo_cancion，nombre_artista]数组，以从http://los40.com.ar/lista40/下载音乐列表。我知道如何使用请求库下载媒体，但是我无法提取页面中的链接和链接

from bs4 import BeautifulSoup
import requests
# import re
url = 'http://los40.com.ar/m/lista40/'
videos = []
response = requests.get(url)
bs = BeautifulSoup(response.text)
for i in range (1,41):
    videos[i]= bs.find_all('datos_camcion_'+i))
# responses= bs.find_all('script', language="javascript", type="text/javascript")

print(videos)

<h3>LISTA DEL 08/06/2019</h3>
<script language="javascript" type="text/javascript">
  var datos_cancion_1 = Array();
  datos_cancion_1['url_audioenci']         = 'https://recursosweb.prisaradio.com/audios/dest/570005645440.mp4';
  datos_cancion_1['url_muzu']         = '';
  datos_cancion_1['url_youtube']      = 'https://www.youtube.com/watch?v=XsX3ATc3FbA';
  datos_cancion_1['url_itunes']       = '';
  datos_cancion_1['posicion']         = '1';
  datos_cancion_1['url_caratula']     = 'https://recursosweb.prisaradio.com/fotos/dest/570005645461.jpg';
  datos_cancion_1['titulo_cancion']   = 'Boy with luv';
  datos_cancion_1['nombre_artista']   = 'BTS;Halsey';
  datos_cancion_1['idYes']            = 'BTS';
  datos_cancion_1['VidAu']            = 0;
</script>

我希望

videos=[['https://recursosweb.prisaradio.com/audios/dest/570005645440.mp4','https://recursosweb.prisaradio.com/fotos/dest/570005645461.jpg','Boy with luv','BTS;Halsey'].....]

Answer 1

我尝试过滤数据：

from bs4 import BeautifulSoup
import requests

url = 'http://los40.com.ar/m/lista40/'
videos = []
response = requests.get(url)
bs = BeautifulSoup(response.text, features="html5lib")

scripts = bs.find_all('script', language='javascript', type='text/javascript') 
end = len( bs.find_all('script', language='javascript', type='text/javascript') )
start = end - 40
data = []

for i in range( start, end ):
    data.append( str(scripts[ i ]) )

print( data[0] )

输出：

<script language="javascript" type="text/javascript">
  var datos_cancion_1 = Array();
  datos_cancion_1['url_audioenci']         = 'https://recursosweb.prisaradio.com/audios/dest/570005645440.mp4';
  datos_cancion_1['url_muzu']         = '';
  datos_cancion_1['url_youtube']      = 'https://www.youtube.com/watch?v=XsX3ATc3FbA';
  datos_cancion_1['url_itunes']       = '';
  datos_cancion_1['posicion']         = '1';
  datos_cancion_1['url_caratula']     = 'https://recursosweb.prisaradio.com/fotos/dest/570005645461.jpg';
  datos_cancion_1['titulo_cancion']   = 'Boy with luv';
  datos_cancion_1['nombre_artista']   = 'BTS;Halsey';
  datos_cancion_1['idYes']            = 'BTS';
  datos_cancion_1['VidAu']            = 0;
</script>

Data [0:39]包含字符串的前40位和所有相关数据，但是我不确定如何从字符串中提取信息。

在this thread中通过import json或import re提出了一些建议，但我无法使它们起作用。

使用Python下载* .mp4文件形式的url
