推荐答案

Facebook 通过 ReactJS构建，因此要对元素进行 click()，您需要诱使 WebDriverWait 使元素可点击，并且您可以使用以下任一方法以下定位器策略:

Facebook is built through ReactJS so to click() on the element you need to induce WebDriverWait for the element to be clickable and you can use either of the following Locator Strategies:

• 使用 css_selector :

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input[aria-label='Add Photo or Video'][name^='composer_photo'][data-testid='media-sprout']"))).click()

使用 xpath :

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//input[@aria-label='Add Photo or Video' and starts-with(@name, 'composer_photo')][@data-testid='media-sprout']"))).click()

注意:您必须添加以下导入:

Note : You have to add the following imports :

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