隐式等待的默认值确实为零，这意味着(并且一直意味着)如果找不到该元素，则会立即使findElement失败. "您不应该直接从findElement收到TimeoutException.使用WebDriverWait构造，在使用所谓的显式等待"时，您可能只会收到该信息.

The default value for implicit waits is indeed zero, which means (and always has meant) "fail findElement immediately if the element can't be found." You shouldn't be receiving a TimeoutException directly from findElement. You'll likely only be receiving that when using a so-called "explicit wait", using the WebDriverWait construct.
