Question

我正在尝试使用this网站自动从Youtube下载mp3文件。

目的：

访问下载网站
粘贴Youtube链接
点击“转换视频”
等待下载链接显示，然后单击

当我使用browser.find_by_id('dl_link').click()时，我的代码执行时没有任何错误，但文件未下载。为什么？

当我使用browser.click_link_by_partial_text（'下载'）时，我收到如下错误。

这是我的代码：

from splinter.browser import Browser
import time

with Browser() as browser:
   browser.visit("http://www.youtube-mp3.org")
   browser.find_by_id('youtube-url').fill("https://www.youtube.com/watch?v=lgT1AidzRWM")
   browser.find_by_id('submit').click()

   if browser.is_element_present_by_id('dl_link'):
      time.sleep(2)
      browser.click_link_by_partial_text('Download')
      # browser.find_by_id('dl_link').click()
      print "Clicked Download"
      time.sleep(2)

以下是我遇到的错误：

我已经检查了相同的其他问题（错误：“元素当前不可见，因此可能无法与”selenuim“标题进行交互）但我仍然无法解决此问题，因为Download按钮在我的情况下可见。

非常感谢任何帮助

编辑：

每当我尝试使用browser = Browser('firefox', profile=profile)设置个人资料时，都会收到以下错误：

当我使用browser.find_by_id（'dl_link'）。click（）时，我的代码执行时没有任何错误但是browser.click_link_by_partial_text（'Download'）会抛出？

因为您与“静态”元素进行交互。

当您点击“转换视频”按钮时，您将刷新DOM。但是你的驱动程序仍然适用于旧的DOM。这就是使用Answer

当它吵架时，不会下载该文件。为什么？的

可能是因为有一个弹出窗口询问您是否要保存并执行它。 $sort
