试图刮掉市场份额，得到“零”

Question

我用python构建了一个基本脚本，用于、、coinmarketcap帽中的一些数据，但我没有得到，我也不知道为什么，你能帮我吗？

from bs4 import BeautifulSoup as S
import requests

c = input('enter your coin')
url = f'https://coinmarketcap.com/currencies/{c}/'

headers = {'user-agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36'}

r = requests.get(url,headers=headers)

soup = S(r.content,'html.parser')

print(f'the price of {c} now is ')
x = soup.find(id="priceValue___11gHJ")
print(x)```

Answer 1

我已经测试了您的代码，并进行了一些更改以使其工作。

要获得的字段使用类而不是id。

看一看。

#!/usr/bin/env python3
from bs4 import BeautifulSoup as S
import requests

c = input('enter your coin')
url = f'https://coinmarketcap.com/currencies/{c}/'

headers = {'user-agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36'}

r = requests.get(url,headers=headers)
soup = S(r.content,'html.parser')
print(f'the price of {c} now is ')
x = soup.find(class_='priceValue___11gHJ').text
print(x)
