无法使用请求从网页中抓取特定字段的值

我正在努力挖掘价值Balance使用请求模块从网页。我找过这个名字Balance在开发工具和页面源代码中但找不到。我希望应该有任何方法来获取价值Balance从该网页，无需使用任何浏览器模拟器。

我追求的输出：

我尝试过：

import requests
from bs4 import BeautifulSoup

link = 'https://tronscan.org/?fbclid=IwAR2WiSKZoTDPWX1ufaAIEg9vaA5oLj9Yd_RUfpjE6MWEQKRGBaK-L_JdtwQ#/contract/TCSPn1Lbdv62QfSCczbLdwupNoCFYAfUVL'

headers = {"User-Agent":"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36"}

res = requests.get(link,headers=headers)
soup = BeautifulSoup(res.text,'lxml')
balance = soup.select_one("li:has(> p:contains('Balance'))").get_text(strip=True)
print(balance)

The reason the page's HTML doesn't have the balance is because the page is making AJAX requests which are sending back the information you want after the page is loaded. You can look at these requests by loading up your developer window by pressing F12 in Chrome (it might be different in other browsers), go to the Network tab and you'll see this:

在这里你可以看到你想要的请求是account?address=接下来是页面 URL 字符串中的代码，将鼠标悬停在该代码上会显示 AJAX 请求的完整 URL（以珊瑚色突出显示），而包含所需数据的响应部分则在右侧以绿松石色突出显示。

您可以通过以下方式查看回复here https://apilist.tronscan.org/api/account?address=TCSPn1Lbdv62QfSCczbLdwupNoCFYAfUVL并找到tokenBalances.

为了在 Python 中获得平衡，您可以运行以下命令：

import requests, json

url = 'https://apilist.tronscan.org/api/account?address=TCSPn1Lbdv62QfSCczbLdwupNoCFYAfUVL'
headers = {"User-Agent":"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.111 Safari/537.36"}

response = requests.get(url, headers=headers)
response = json.loads(response.text)

balance = response['tokenBalances'][0]['balance']

print(balance)
