【问题描述】：
我正在使用 requests.get() 来解析 youtube HTML 文本。当我在传递链接后打印输出时，一个视频出现故障。我正在尝试使用 BeautifulSoup 按顺序播放视频，并且出现故障的视频在所有其他视频之前显示。任何建议或可能的修复都会有所帮助。
true = requests.get(link +searched)
page = true.text
#print(page)
soup = BeautifulSoup(page, 'html.parser')
#print(soup)
search_results = soup.findAll('a', attrs={'class': 'yt-uix-tile-link'})
#print(search_results)
更多参考代码：
import pafy
import vlc
import requests
from bs4 import BeautifulSoup
import time
link="https://www.youtube.com/results?search_query="
youtube = "https://www.youtube.com"
word = "jid playlist"
def findlnks(searched):
if '&list' not in searched:
true = requests.get(link +searched)
page = true.text
#print(page)
soup = BeautifulSoup(page, 'html.parser')
#print(soup)
search_results = soup.findAll('a', attrs={'class': 'yt-uix-tile-link'})
#print(search_results)
else:
true = requests.get(searched)
page = true.text
soup = BeautifulSoup(page, 'html.parser')
#print(soup)
search_results = soup.findAll('a', class_ ="spf-link playlist-video clearfix yt-uix-sessionlink spf-link")
#print(search_results)
return search_results
if 'mix' in word or 'playlist' in word:
total_results = findlnks(word)
i =0
playlist_size=0
#while i< 10:
#print(total_results[i]['title'])
#i+=1
while 'list' not in (total_results[i])['href']:
print(total_results[i]['href'])
i = i + 1
playlist_results=findlnks(youtube + ((total_results[i])['href']))
while playlist_size<40:
#print(youtube + (playlist_results[playlist_size])['href'])
playlist_size = playlist_size +1
while (playlist_results[playlist_size])['href'] !='\0':
url = youtube + (playlist_results[playlist_size])['href']
#print(url)
video = pafy.new(url)
best = video.getbest()
playurl = best.url
Instance = vlc.Instance()
player = Instance.media_player_new()
media = Instance.media_new(playurl)
media.get_mrl()
player.set_media(media)
player.play()
playing = set([1, 2, 3, 4])
time.sleep(1)
duration = player.get_length() / 1000
mm, ss = divmod(duration, 60)
while True:
state = player.get_state()
if state not in playing:
break
continue
playlist_size = playlist_size +1

你能分享你的
link+searched吗？ -
对于您的搜索结果，您到底在寻找什么？

@HjSin 我编辑了我的帖子，所以它包含了我到目前为止的大部分内容。这应该提供更好的上下文。这部分是在初始搜索结果中搜索播放列表，然后再次调用 findlks 来获取播放列表中视频的 url。它有效，它们只是不符合 youtube 提供的顺序。你会注意到我还有一个块，它可以播放从 VLC 媒体播放器的播放列表中检索到的视频。一旦另一个视频结束，我在播放视频时遇到了一些问题。
