数据是从另一个URL动态加载的。要获得该频道的实际观众人数，您可以尝试以下脚本：

import requests
from bs4 import BeautifulSoup

username = 'f1nn5ter'
url = 'https://gql.twitch.tv/gql#origin=twilight'
data = "[{"operationName":"ChannelRoot_SocialMediaSpace","variables":{"channelLogin":""+username+""},"extensions":{"persistedQuery":{"version":1,"sha256Hash":"3cc9b2fc1ce60c0d0bd271e795e6c9d0baef0d7cb8a0f130c5311f4d045157da"}}},{"operationName":"StreamMetadata","variables":{"channelLogin":""+username+""},"extensions":{"persistedQuery":{"version":1,"sha256Hash":"1c719a40e481453e5c48d9bb585d971b8b372f8ebb105b17076722264dfa5b3e"}}},{"operationName":"UseViewCount","variables":{"channelLogin":""+username+""},"extensions":{"persistedQuery":{"version":1,"sha256Hash":"00b11c9c428f79ae228f30080a06ffd8226a1f068d6f52fbc057cbde66e994c2"}}},{"operationName":"UseLiveBroadcast","variables":{"channelLogin":""+username+""},"extensions":{"persistedQuery":{"version":1,"sha256Hash":"5ab2aee4bf1e768b9dc9020a9ae7ccf6f30f78b0a91d5dad504b29df4762c08a"}}},{"operationName":"Drops_ChannelDrops_User","variables":{"login":""+username+"","isLoggedIn":false},"extensions":{"persistedQuery":{"version":1,"sha256Hash":"f309b1d517d288074d50d96512059857cc67d8905d1379e414d70f7b981f2618"}}},{"operationName":"RealtimeStreamTagList","variables":{"channelLogin":""+username+""},"extensions":{"persistedQuery":{"version":1,"sha256Hash":"9d952e4aacd4f8bb9f159bd4d5886d72c398007249a8b09e604a651fc2f8ac17"}}}]"
headers = {
'Client-Id': 'kimne78kx3ncx6brgo4mv6wki5h1ko'
}
def traverse(d):
if isinstance(d, dict):
for k, v in d.items():
if k == 'viewersCount':
yield v
return
yield from traverse(v)
elif isinstance(d, list):
for v in d:
yield from traverse(v)
d = requests.post(url, headers=headers, data=data).json()
print(next(traverse(d)))
