XPATH 是比 ID 更好的方法。我尝试过使用 XPATH 并且它对我有用。

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

driver = webdriver.Chrome()
driver.get("https://opensource-demo.orangehrmlive.com/")

wait = WebDriverWait(driver, 20)

# Wait for the username field to be present
username_field = wait.until(EC.presence_of_element_located((By.XPATH, '//*[@id="app"]/div[1]/div/div[1]/div/div[2]/div[2]/form/div[1]/div/div[2]/input')))
username_field.send_keys("Admin")

password_field = driver.find_element(By.XPATH, '//*[@id="app"]/div[1]/div/div[1]/div/div[2]/div[2]/form/div[2]/div/div[2]/input')
password_field.send_keys("admin123")
time.sleep(5)
# Assuming there's a login button with ID 'btnLogin'
login_button = driver.find_element(By.XPATH, '//*[@id="app"]/div[1]/div/div[1]/div/div[2]/div[2]/form/div[3]/button')
login_button.click()
time.sleep(20)
