我使用這個Python 3代碼從網頁獲取一些下載網址，當網頁打開時，我想向元素發送一個點擊事件，并觸發生成下載網址，然后獲取下載網址，但現在我無法觸發單擊事件，顯示如下錯誤：

這是我觸發下載事件的代碼：
from selenium.webdriver.chrome.service import Service
from selenium import webdriver
from selenium.webdriver.common.by import By
from webdriver_manager.chrome import ChromeDriverManager
class FetchMusic:
def __init__(self):
print("fetch...")
if __name__ == '__main__':
s = Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=s)
# driver.maximize_window()
driver.get('http://tool.liumingye.cn/music/?page=audioPage&type=migu&name=Unstoppable')
driver.implicitly_wait(5)
driver.find_element(By.CSS_SELECTOR, "aplayer-list-download iconfont icon-xiazai").click()
modal_body = driver.find_element(By.CLASS_NAME, "modal-body").get_attribute("href")
# results = driver.page_source
for result in modal_body:
print(result.text)
我該怎么做才能讓它發揮作用？
uj5u.com熱心網友回復：
您忘記.在類名稱之前添加類選擇器。
driver.find_element(By.CSS_SELECTOR, ".aplayer-list-download.iconfont.icon-xiazai").click()
下一行將不起作用
modal_body = driver.find_element(By.CLASS_NAME, "modal-body").get_attribute("href")
因為模態主體 div 沒有屬性呼叫href，所以如果你想提取模態主體 div 內的所有 URL，你可以使用 JavaScript 中的 querySelector API。見下文
urls = [a.get_attribute('href') for a in driver.execute_script('return document.querySelectorAll(".modal-body a[href*=\'http\']")')]
