2.按F12獲取headers

3.右鍵查看源代碼

4.代碼實現

import requests
import pandas as pd
from bs4 import BeautifulSoup
from pandas import DataFrame
url='https://tophub.today/n/L4MdA5ldxD'
def getHTMLText(url):
    try:
        headers={'user-agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3314.0 Safari/537.36 SE 2.X MetaSr 1.0'}
        r=requests.get(url,timeout=30,headers=headers)
        r.raise_for_status()
        r.encoding='utf-8'
        return r.text
    except:
        return'異常'
def saveHTMLText(title,html,c):
        soup=BeautifulSoup(html,'html.parser')
        a=soup.find_all('span',class_='t')
        print('排名', '標題')
        index=[i for i in range(c)]
        print(index)
        title.append(a)      
        title=[]
        saveHTMLText(title,html,c=10)
        html=getHTMLText(url)
        df=pd.DataFrame(title,columns=['排名','標題'])
        print(df.T)
