python - AutoIT 脚本以某种方式未检测到网站上的下载按钮

问题描述

我正在尝试编写一个 AutoIT 脚本，该脚本将通过 Internet Explorer 自动导航到 URL（https://www.macrotrends.net/1476/copper-prices-historical-chart-data）并单击一个按钮（红色，标记为“下载历史数据”）将下载 Excel 数据文件。通过检查这个按钮，我发现它有一个 id（“dataDownload”），但是我在 AutoIT 中使用 _IEGetObjById 函数的尝试没有成功。这是我的脚本：

#include <IE.au3>

Local $oIE = _IECreate("https://www.macrotrends.net/1476/copper-prices-historical-chart-data", 1)
Local $oButton = _IEGetObjById($oIE, "dataDownload")
_IEAction($oButton, "click")

该脚本正在打开 Internet Explorer，但我认为它没有按预期检测按钮。我的怀疑是，这可能是因为按钮位于框架或容器或您可能称之为的任何内容中？

此外，我的意图是让这个 AutoIT 脚本由 Windows 上的批处理文件调用，并按计划运行。如果您有任何其他推荐的用于此类自动网络抓取的方法，请随时启发。

非常感谢我能得到的所有帮助。

解决方案

这是使用https://www.autoitscript.com/forum/topic/153520-iuiautomation-ms-framework-automate-chrome-ff-ie/的工作示例 您可以忽略大多数全局变量。我将其用作我编写的另一个脚本的模板。
