问题

在以下代码中，我无法在相应的字段中发送用户名或密码。我每次都收到一个"元素不可交互"的异常。请问有人可以告诉我如何解决这个问题吗？

from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException, ElementNotInteractableException
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.common.by import By
import sys

def main():
    path = r'path\to\chromedriver.exe'
    options = webdriver.ChromeOptions()
    driver = webdriver.Chrome(executable_path=path, options=options)
    driver.get("https://banking.dkb.de/login")

    try:
        # 接受cookies #
        frame = driver.find_element(By.XPATH, "//iframe[@id='privacy-iframe']")
        driver.switch_to.frame(frame)
        button = driver.find_element(By.XPATH, "//button[@aria-label='Refuse all cookies']")
        button.click()

        # 为了能够在接受cookies后找到元素
        driver.get("https://banking.dkb.de/login")

        # 登录
        element = driver.find_element(By.XPATH, "//input[@id='username']")
        element.send_keys("123456789")
        element = driver.find_element(By.XPATH, "//input[@id='password']")
        element.send_keys("abcdefg")
        element = driver.find_element(By.XPATH, "//div[@class='sc-11z3xzm-3 bFajen']/button")
        element.click()

    except NoSuchElementException:
        print('元素未找到')
        driver.close()
        driver.quit()
        sys.exit(0)

    except TimeoutException:
        print('超时异常')
        driver.close()
        driver.quit()
        sys.exit(0)

    except ElementNotInteractableException:
        print('元素不可交互')
        driver.close()
        driver.quit()
        sys.exit(0)

main()

我尝试设置隐式等待和显式等待，以及通过JavaScript点击字段来设置值，但仍然没有起作用。有人可以帮助我解决这个问题吗？

def main():

        driver.switch_to.frame(frame)
        button = driver.find_element(By.XPATH, "//button[@aria-label='Refuse all cookies']")
        button.click()

        # In order to be able to find the elements after accepting cookies
        driver.get("https://banking.dkb.de/login")

        #Logging in

Selenium Actions应该能帮助您在这种情况下

from selenium.webdriver.common.action_chains import ActionChains

actions = ActionChains(driver)
driver.find_element(By.CSS_SELECTOR("[data-testid=sui-input-username]")).click();
# 登录
element = driver.find_element(By.XPATH, "//input[@id='username']")
actions.send_keys('login', element).perform()

我在Java中为您的网站采用了类似的方法，它对我有效。此外，我认为您在关闭Cookie模态窗口后不需要刷新页面。您只需等待模态窗口不可见，然后切换回默认上下文。

检查模态窗口的不可见性

refuseButtonSelector = "//button[@aria-label='Refuse all cookies']"
wait = WebDriverWait(driver, 10)
button = driver.find_element(By.XPATH, refuseButtonSelector)
button.click()

wait.until(EC.invisibility_of_element_located((By.XPATH, refuseButtonSelector)))
driver.switch_to.default_content()

from selenium.webdriver.common.action_chains import ActionChains
actions = ActionChains(driver)
driver.find_element(By.CSS_SELECTOR("[data-testid=sui-input-username]")).click();
#Logging in
element = driver.find_element(By.XPATH, "//input[@id='username']")
actions.send_keys('login', element).perform()

refuseButtonSelector = "//button[@aria-label='Refuse all cookies']"
wait = WebDriverWait(driver, 10)
button = driver.find_element(By.XPATH, refuseButtonSelector)
button.click()
wait.until(EC.invisibility_of_element_located((By.XPATH, refuseButtonSelector)))
driver.switch_to.default_content()

以下是翻译好的部分：

这是完整的解决方案：
```python
import time
from selenium.webdriver import Chrome, Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
import selenium.webdriver.support.expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains

def main():
    driver = Chrome()
    driver.get("https://banking.dkb.de/login")
    wait = WebDriverWait(driver, 10)

    # 切换到iframe并点击拒绝所有cookie的按钮
    iframe = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, 'iframe#privacy-iframe')))
    driver.switch_to.frame(iframe)
    driver.find_element(By.CSS_SELECTOR, 'button.btn.refuse-all').click()

    driver.get("https://banking.dkb.de/login")

    actions = ActionChains(driver)

    wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'div[data-testid="sui-input-username"]'))).click()
    username = driver.find_element(By.CSS_SELECTOR, 'input#username')
    actions.move_to_element(username).send_keys('123456789').perform()

    wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'div[data-testid="sui-input-password"]'))).click()
    password = driver.find_element(By.CSS_SELECTOR, 'input#password')
    actions.move_to_element(password).send_keys('abcdefg').perform()

    password.send_keys(Keys.ENTER)
    time.sleep(2)

main()

输出：

一些注意事项：

• 网站可能会在iframe中显示一个cookie同意弹出窗口。因此，切换到相应的iframe并点击按钮拒绝所有cookie。

  iframe = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, 'iframe#privacy-iframe')))
  driver.switch_to.frame(iframe)
  driver.find_element(By.CSS_SELECTOR, 'button.btn.refuse-all').click()
  

• 初始化ActionChains以执行鼠标移动和按键操作。

  actions = ActionChains(driver)
  

• 使用提供的凭据登录，找到用户名输入字段，点击它，并输入用户名。

  wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'div[data-testid="sui-input-username"]'))).click()
  username = driver.find_element(By.CSS_SELECTOR, 'input#username')
  actions.move_to_element(username).send_keys('123456789').perform()
  

• 找到密码输入字段，点击它，并输入密码。

  wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'div[data-testid="sui-input-password"]'))).click()
  password = driver.find_element(By.CSS_SELECTOR, 'input#password')
  actions.move_to_element(password).send_keys('abcdefg').perform()
  

• 按Enter键提交登录表单。

  password.send_keys(Keys.ENTER)

Here&#39;s the complete solution:
```python
import time
from selenium.webdriver import Chrome, Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.wait import WebDriverWait
import selenium.webdriver.support.expected_conditions as EC
from selenium.webdriver.common.action_chains import ActionChains
def main():
driver = Chrome()
driver.get(&quot;https://banking.dkb.de/login&quot;)
wait = WebDriverWait(driver, 10)
# Switch to the iframe and click on the button to refuse all cookies
iframe = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, &#39;iframe#privacy-iframe&#39;)))
driver.switch_to.frame(iframe)
driver.find_element(By.CSS_SELECTOR, &#39;button.btn.refuse-all&#39;).click()
driver.get(&quot;https://banking.dkb.de/login&quot;)

wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, &#39;div[data-testid=&quot;sui-input-username&quot;]&#39;))).click()
username = driver.find_element(By.CSS_SELECTOR, &#39;input#username&#39;)
actions.move_to_element(username).send_keys(&#39;123456789&#39;).perform()
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, &#39;div[data-testid=&quot;sui-input-password&quot;]&#39;))).click()
password = driver.find_element(By.CSS_SELECTOR, &#39;input#password&#39;)
actions.move_to_element(password).send_keys(&#39;abcdefg&#39;).perform()
password.send_keys(Keys.ENTER)
time.sleep(2)
main()

output:

Few notes:

• The website may display a cookie consent popup within an iframe. Therefore, switch to the respective iframe and click on the button to refuse all cookies.

  iframe = wait.until(EC.presence_of_element_located((By.CSS_SELECTOR, 'iframe#privacy-iframe')))
  driver.switch_to.frame(iframe)
  driver.find_element(By.CSS_SELECTOR, 'button.btn.refuse-all').click()
  

• Initialize ActionChains to perform actions like mouse movements and keystrokes

  actions = ActionChains(driver)
  

• Log in with provided credentials, Find the username input field, click on it, and enter the username.

  wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'div[data-testid="sui-input-username"]'))).click()
  username = driver.find_element(By.CSS_SELECTOR, 'input#username')
  actions.move_to_element(username).send_keys('123456789').perform()
  

• Find the password input field, click on it, and enter the password.

  wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'div[data-testid="sui-input-password"]'))).click()
  password = driver.find_element(By.CSS_SELECTOR, 'input#password')
  actions.move_to_element(password).send_keys('abcdefg').perform()
  

• Press the Enter key to submit the login form.

  password.send_keys(Keys.ENTER)
