python - 使用phantomjs获取链接地址

Question

我正在尝试获取此页面上每个 div 的文章网址:https://www.google.com/trends/home/all/IN我可以获得图像链接和标题，但对于文章链接，它给出

Traceback (most recent call last):
  File "google.py", line 25, in getGooglerends
    print s.find_elements_by_class_name('image-wrapper').get_attribute('href')
AttributeError: 'list' object has no attribute 'get_attribute'

代码:

driver = webdriver.PhantomJS('/usr/local/bin/phantomjs')
driver.set_window_size(1124, 850)
driver.get("https://www.google.com/trends/home/all/IN")
trend = {}
def getGooglerends():
    try:
    #Does this line makes any sense
        #element = WebDriverWait(driver, 20).until(lambda driver: driver.find_elements_by_class_name('md-list-block ng-scope'))
        for s in driver.find_elements_by_class_name('md-list-item-block'):
            print s.find_element_by_tag_name('img').get_attribute('src')
            print s.find_element_by_tag_name('img').get_attribute('alt')
            print s.find_elements_by_class_name('image-wrapper').get_attribute('href')
    except:
        import traceback
        print traceback.format_exc()
getGooglerends()

对于从 anchor 标记获取文章链接有什么建议吗？

Answer 1

WebDriver.find_elements_by_class_name返回元素列表，而不是单个元素。

s.find_elements_by_class_name('image-wrapper')
              ^

使用WebDriver.find_element_by_class_name而不是WebDriver.find_elements_by_class_name .

s.find_element_by_class_name('image-wrapper')
