AttributeError：'str'对象没有属性'findAll'，在使用BeautifulSoup从Youtube抓取数据中没有输出

Question

我正在尝试从YouTube抓取热门视频。我无法从youtbue获取href标签。我的代码和预期输出如下。您将可以用url = 'https://www.youtube.com/watch?v=tL8AOS9ZRMg'提取数据，并注释将要使用的零件for link in youtubelinks: and correct the indentation。导入BeautifulSoup，urllib，ssl，os。我正在尝试转换为json格式并保存。

我的代码在下面

import urllib.request
import urllib.parse
import urllib.error
from bs4 import BeautifulSoup
import ssl
import json
import ast
import json
import os
from urllib.request import Request, urlopen

# For ignoring SSL certificate errors

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

# Input from user

#url = input('Enter Youtube Video Url- ')
#url = 'https://www.youtube.com/watch?v=MxnkDj8PIxQ'
url = 'https://www.youtube.com/feed/trending'
# Making the website believe that you are accessing it using a mozilla browser

req = Request(url, headers={'User-Agent': 'Mozilla/5.0'})
webpage = urlopen(req).read()

# Creating a BeautifulSoup object of the html page for easy extraction of data.

soup = BeautifulSoup(webpage, 'html.parser')
html = soup.prettify('utf-8')
video_details = {}
other_details = {}

#All the trending youtube links
a = soup.select('a[href^="/watch?v="]')[:3]
youtubelinks = list(set("https://www.youtube.com" + do.get('href', None) for do in a))
youtubelinks
#print (doc)
for link in youtubelinks:
    for span in link.findAll('span',attrs={'class': 'watch-title'}):
        #video_details['TITLE'] = span.text.strip()
        video_details['TITLE'] = span.text.encode('utf8')

    for script in link.findAll('script',attrs={'type': 'application/ld+json'}):
            channelDesctiption = json.loads(script.text.strip())
            video_details['CHANNEL_NAME'] = channelDesctiption['itemListElement'][0]['item']['name']

    for div in link.findAll('div',attrs={'class': 'watch-view-count'}):
        video_details['NUMBER_OF_VIEWS'] = div.text.strip()

    for button in link.findAll('button',attrs={'title': 'I like this'}):
        video_details['LIKES'] = button.text.strip()

    for button in link.findAll('button',attrs={'title': 'I dislike this'}):
        video_details['DISLIKES'] = button.text.strip()

    for span in link.findAll('span',attrs={'class': 'yt-subscription-button-subscriber-count-branded-horizontal yt-subscriber-count'}):
        video_details['NUMBER_OF_SUBSCRIPTIONS'] = span.text.strip()

    hashtags = []
    for span in link.findAll('span',attrs={'class': 'standalone-collection-badge-renderer-text'}):
        for a in link.findAll('a',attrs={'class': 'yt-uix-sessionlink'}):
            hashtags.append(a.text.strip())
    video_details['HASH_TAGS'] = hashtags

    with open('output_file.html', 'wb') as file:
        file.write(html)

    with open('data.json', 'w', encoding='utf8') as outfile:
        json.dump(video_details, outfile, ensure_ascii=False,indent=4)

    print ('----------Extraction of data is complete. Check json file.----------')

我的期望值

{ 1. {
    "TITLE": "A",
    "CHANNEL_NAME": "B"
    "NUMBER_OF_VIEWS": "8,945 views",
    "LIKES": "71",
    "DISLIKES": "6",
    "NUMBER_OF_SUBSCRIPTIONS": "13.3K",
    "HASH_TAGS": [
        "#A",
        "#B",
        "#C"
    ]
}

2.{
    "TITLE": "D",
    "CHANNEL_NAME": "E",
    "NUMBER_OF_VIEWS": "8,945 views",
    "LIKES": "71K",
    "DISLIKES": "6K",
    "NUMBER_OF_SUBSCRIPTIONS": "1.3M",
    "HASH_TAGS": [
        "#M",
        "#F",
        "#G"
    ]
}
}
