我正在嘗試在網站上抓取一張桌子。問題是<tbody>html代碼中沒有。我厭倦了請求和硒，但總是相同的結果。有沒有人有任何想法？
這是代碼（帶有請求）網站：https : //bscscan.com/token/0xAdeaE50E0097fBf8139Bdff45e7ed00de4b14170#balances
from urllib.request import Request, urlopen
import bs4
link="https://bscscan.com/token/0xAdeaE50E0097fBf8139Bdff45e7ed00de4b14170#balances"
req = Request(link, headers={'User-Agent': 'Mozilla/5.0'})
webpage = urlopen(req).read()
soup = bs4.BeautifulSoup(webpage,"html.parser" )
print(soup)
這是硒：
import time
import bs4
from selenium import webdriver
from webdriver_manager.microsoft import EdgeChromiumDriverManager
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
driver = webdriver.Edge(service=Service(EdgeChromiumDriverManager().install()))
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver.get("https://bscscan.com/token/0xAdeaE50E0097fBf8139Bdff45e7ed00de4b14170#balances")
time.sleep(7)
html=driver.page_source
soup=bs4.BeautifulSoup(html,"lxml" )
print(soup)
WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".table > tbody:nth-child(2)")))
print(driver.page_source)
uj5u.com熱心網友回復：
您嘗試訪問的表位于 iframe 內。您需要切換到該 iframe 才能訪問該元素：
import time
import bs4
from selenium import webdriver
from webdriver_manager.microsoft import EdgeChromiumDriverManager
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
driver = webdriver.Edge(service=Service(EdgeChromiumDriverManager().install()))
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
driver.get("https://bscscan.com/token/0xAdeaE50E0097fBf8139Bdff45e7ed00de4b14170#balances")
time.sleep(7)
html=driver.page_source
soup=bs4.BeautifulSoup(html,"lxml" )
print(soup)
WebDriverWait(driver, 10).until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR,"iframe#tokeholdersiframe")))
WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".table > tbody:nth-child(2)")))
print(driver.page_source)
完成后，您將不得不切換回默認內容
driver.switch_to.default_content()
