当我在 Tkinter 和 Selenium 中使用用户和密码的文本框登录 Facebook 时出现问题

Question

我想在 tkinter window 中输入用户名和密码后登录 Facebook。问题是，在输入用户名和密码后，当我点击登录按钮时，Facebook 页面打开但没有登录。可能是 driver.find_element 的问题。怎么解决？注意：请不要更改我与 Firefox 的连接方式。

如果您运行在控制台中编写代码，那么您应该会看到错误，这有助于您发现问题。

你有两个错误。

你以错误的方式使用 find_element() - 它必须是 find_element(By.ID, 'email') 最终更旧 find_element_by_id('email')（pass 和 [=17 相同=]
您必须使用 .get() 从 Entry 获取文本 - 因此您需要 email.get() 和 password.get()

    username_box = driver.find_element(By.ID, 'email')
    username_box.send_keys(email.get())
      
    password_box = driver.find_element(By.ID, 'pass')
    password_box.send_keys(password.get())
      
    login_box = driver.find_element(By.ID, 'loginbutton')
    login_box.click()

还有其他问题（至少在我的电脑上）- 开始时它显示有关 cookie 的消息，我必须关闭它，因为它隐藏了 loginbutton 并且 Selenium 无法单击它。

编辑：

要关闭 cookie 消息，您必须使用正确的 css 选择器

(By.CSS_SELECTOR, 'button[data-cookiebanner="accept_only_essential_button"]')

而且您必须等待超过 1 秒。
