selenium.common.exceptions.TimeoutException：消息：尝试打印节目标题时出错

Question

我在运行这个简短的脚本中看到上面的错误：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

url ='https://animelon.com/'

PATH = 'C:\Program Files (x86)\chromedriver.exe'
driver = webdriver.Chrome(PATH)
driver.get(url)

try:
    section = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.CLASS_NAME, 'row ng-show-toggle-slidedown series-content-container'))
    )

    anime = section.find_elements_by_class_name('col-lg-3 col-md-4 col-sm-6 col-xs-12 mini-previews ng-scope')

    for show in anime:
        header = show.find_element_by_class_name('anime-name ng-binding')
        print(header.text)

finally:
    driver.quit()

我看到了这个错误的不同答案，但它们都太过case-specific所以我决定自己做一个post。如果您有任何方法可以解决此错误，请告诉我。提前致谢！

编辑：我尝试简单地将超时从 10 增加到 30 等等。但是出现同样的错误

Answer 1

您使用了错误的定位器。
由于您通过多个 class 名称定位元素，因此您应该使用 CSS_SELECTOR，而不是 By.CLASS_NAME
此外，您应该等待元素可见性，而不仅仅是存在。
此外，要搜索元素内部的元素，建议使用以点 . 开头的 XPath，就像我在此处使用的那样。
看看这是否适合您：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

url ='https://animelon.com/'

PATH = 'C:\Program Files (x86)\chromedriver.exe'
driver = webdriver.Chrome(PATH)
driver.get(url)

try:
    section = WebDriverWait(driver, 10).until(
        EC.visibility_of_element_located((By.CSS_SELECTOR, '.row.ng-show-toggle-slidedown.series-content-container'))
    )

    anime = section.find_elements_by_xpath('.//*[@class="col-lg-3 col-md-4 col-sm-6 col-xs-12 mini-previews ng-scope"]')

    for show in anime:
        header = show.find_element_by_xpath('.//*[@class="anime-name ng-binding"]')
        print(header.text)

finally:
    driver.quit()
