當我在Tkinter和Selenium中使用用戶和密碼的文本框登錄Facebook時出現問題

我想在 tkinter 視窗中輸入用戶名和密碼后登錄 Facebook。問題是，在輸入用戶名和密碼后，當我點擊登錄按鈕時，facebook 頁面打開但沒有登錄。可能是 driver.find_element 有問題。怎么解決？注意：請不要更改我與 Firefox 的連接方式。

uj5u.com熱心網友回復：

如果您要在控制臺中運行代碼，那么您應該會看到有助于您發現問題的錯誤。

你有兩個錯誤。

• 您find_element()以錯誤的方式使用 - 它find_element(By.ID, 'email')最終必須更舊find_element_by_id('email')（對于pass和button

• 你必須使用.get()來獲取文本Entry- 所以你需要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()

還有其他問題（至少在我的計算機上） - 在開始時它顯示有關 cookie 的訊息，我必須關閉它，因為它隱藏loginbutton并且 Selenium 無法單擊它。

編輯：

要關閉 cookie 訊息，您必須使用正確的 css 選擇器

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

你必須等待超過 1 秒。
