我制作了一個點擊各種 Instagram 提示的程式，我使用 CSS_SELECTOR 來識別這些按鈕并點擊它們。問題是，它只是有時有效。在這些情況下
wait.until(ec.element_to_be_clickable((By.CSS_SELECTOR, ".aOOlW.bIiDR"))).click()
wait.until(ec.element_to_be_clickable((By.CSS_SELECTOR, ".aOOlW.HoLwm"))).click()
CSS_SELECTOR 作業正常，但在這種情況下
wait.until(ec.element_to_be_clickable((By.CSS_SELECTOR, "sqdOP.L3NKy.y3zKF"))).click()
它不起作用并回傳此錯誤：
Traceback (most recent call last):

我做錯了什么，我怎樣才能讓 selenium 識別每個按鈕，而不僅僅是一些？
（這是我的完整代碼：）

uj5u.com熱心網友回復：
您的代碼沒有錯，但在定位器策略中沒有錯。
By.CSS_SELECTOR, ".aOOlW.bIiDR"表示您正在使用類名來定位元素，并且這些類名是動態生成的。因此，每次訪問 AUT（被測應用程式）時，您都不會找到以前執行的類名，因為它們是在每次訪問時重新隨機生成的。
因此找不到所需的元素，并且由于wait包裝器，您會看到TimeoutException錯誤。
