如何使用beautifulsoup从中获取价值？

Question

我正在尝试学习beautifulsoup，并正在抓取该网站。 我的python代码如下所示：

import requests
from bs4 import BeautifulSoup


print("Enter the last 3 characters from the share link")
share_link = input()
link = "https://website.com" + share_link
print(link)
r = requests.get(link)
raw = r.text

soup = BeautifulSoup(raw, features="html.parser")

print(soup.prettify)

inputTag = soup.find("input", {"id": "hiddenInput"})
output = inputTag["value"]

print(output)

它给了我这个输出：

{"broadcastId":"BroadcastID: 252940","rtmp_url":"rtmp://live.gchao.cn/live/23331_9wx2w0c9","sex":0,"accountType":"26073","hls_url":"http://live.gchao.cn/live/23331_9wx2w0c9.m3u8","onlineNum":99,"likeNum":67,"live_id":282878,"flv_url":"http://live.gchao.cn/live/23331_9wx2w0c9.flv?txSecret=40d318efbbbca6afb8be2450b8d1f8fa&txTime=5D6086D1","user_id":252940,"stream_id":"23331_9wx2w0c9","nick_name":"Princess","sdkAppID":"1400088004","info_id":33189,"info_name":"Hi","IM_ID":"@TGS#aXMZYZ7FB","earning":424}

我如何才能进入其中，并通过beautifulsoup获得值？

Answer 1

如果是json，则可以加载json库，然后解析例如

import json

s = '{"broadcastId":"BroadcastID: 252940","rtmp_url":"rtmp://live.gchao.cn/live/23331_9wx2w0c9","sex":0,"accountType":"26073","hls_url":"http://live.gchao.cn/live/23331_9wx2w0c9.m3u8","onlineNum":99,"likeNum":67,"live_id":282878,"flv_url":"http://live.gchao.cn/live/23331_9wx2w0c9.flv?txSecret=40d318efbbbca6afb8be2450b8d1f8fa&txTime=5D6086D1","user_id":252940,"stream_id":"23331_9wx2w0c9","nick_name":"Princess","sdkAppID":"1400088004","info_id":33189,"info_name":"Hi","IM_ID":"@TGS#aXMZYZ7FB","earning":424}'
data = json.loads(s)
print(data['broadcastId'])
