需求：遍历QQ邮箱的在线文档并下载  
关于QQ邮箱自动登录的问题可以参考：[python实现滑动验证][python]

> 文件列表的xpath:/html/body/div\[2\]/div/div\[2\]/div\[2\]/div\[2\]/ul  
> 每个文件的xpath:/html/body/div\[2\]/div/div\[2\]/div\[2\]/div\[2\]/ul/li\[i\]

直接上代码：

def download_onlinedoc():
        global browser
        onlinedoc_button=browser.find_element_by_id('folder_onlinedoc_td')
        onlinedoc_button.click()
        time.sleep(2)
        browser.switch_to.frame('mainFrame')
        current_url1=browser.current_url
        print("进入第一层框架:",current_url1)
        time.sleep(2)
        browser.switch_to.frame('onlineDoc_detail_iframe')
        current_url2 = browser.current_url
        print("进入第二层框架:", current_url2)
        time.sleep(2)
        docList=browser.find_element_by_class_name('index_docList')
        alldocs=docList.find_elements_by_class_name('index_docItem')
        print("一共含有{}个文件".format(len(alldocs)))
        for x in alldocs:
            print(x)
            opreations=x.find_element_by_class_name("index_docItem_operation")
            opreations.click()
            time.sleep(2)
            menus=opreations.find_element_by_class_name('od_dropdownMenu')
            menusidd=menus.find_element_by_id('menu')
            dowload_button=menusidd.find_element_by_class_name('od_dropdownMenu_item.od_tipsBubbleWrap')
            dowload_button.click()
            # pyautogui.hotkey('down')
            pyautogui.hotkey('enter')
            time,sleep(2)
            pyautogui.click(250,600)
        browser.refresh()
        time.sleep(5)

注意：  
\*\*1.alldocs=docList.find\_elements\_by\_class\_name(‘index\_docItem’)获取文件列表，得到一个list  
2.嵌套元素元素需要一层一层的获取，不能跨层获取，不熟悉的话可以用xpath来理一下  
3.网页元素会变动（比如点击按钮出现新的下拉框），获取到哪一层就前进到那层并使用find\_element\_xxx定位，不要提前点开，否则可能会出错！\*\*比如下面这个：

最右边的那个元素：

> class=“index\_docItem\_operation”

但是点击之后就变了：

> class=“index\_docItem\_operation index\_docItem\_operation\_BottomShow”

个人踩坑记录，欢迎交流讨论！
