使用python中的api将图像从驱动器插入幻灯片

Question

我正在尝试将google drive中的图像插入到现有幻灯片演示文稿中，但出现错误

Invalid requests[0].createImage: The provided image was not found

我已经尝试了几种方法来生成一个可以工作的链接(fig_url 2-8)。此外，我手动设置文件夹，幻灯片文件和图像文件的权限为“任何人与此链接可以查看”。但是，唯一有效的链接仍然是在线链接(fig_url1)。

此外，如果有一种方法可以在不运行flow (打开浏览器)的情况下完成这项工作，那将是最好的。

Answer 1

你需要做两件事

1. documentation指定必须将图像设置为可公开访问(您已经这样做了)
2. 此外，需要指定为documentation的图像的链接是
3. url

两者的组合应该使您能够将图像插入到幻灯片中。
