python - Selenium 无法获取结果页面上第一张图像的 Alt 属性

问题描述

Selenium 无法获取图像的属性，这是我通过以下方法（类名）获得的。我究竟做错了什么？这发生在亚马逊惠普上。

def getByClass(InputElement, amazonDriver):
    getByClass = WebDriverWait(amazonDriver, 10).until(EC.visibility_of_element_located((By.CLASS_NAME, InputElement)))
    return getByClass

现在我这样称呼它：

amazonResultImage = getByClass('s-image', amazonDriver)
assert 'George Duke' in amazonResultImage.get_attribute("alt")

现在我收到此错误消息：

  File "./amazon.py", line 23, in <module>
    assert 'Dream on by George Duke (2011-11-22)' in amazonResultImage.get_attribute("alt")
  File "/usr/local/lib/python3.6/dist-packages/selenium/webdriver/remote/webelement.py", line 143, in get_attribute
    resp = self._execute(Command.GET_ELEMENT_ATTRIBUTE, {'name': name})
