推荐答案
事实证明,返回的默认共享URL是短url ,并且短url将始终指向Dropbox预览页面.
It turns out that the default share url that is returned is a short url and the short url will always point to the Dropbox preview page.
因此,您需要通过将short_url参数设置为false来获取REST API以返回完整的url.拥有完整的网址后,请在网址末尾添加?dl = 1.
Therefore, you need to get the REST API to return the full url by setting the short_url parameter to false. Once you have the full url, then add ?dl=1 at the end of url.
例如: https://dl.dropbox.com/s /xxxxxxxxxxxxxxxxxx/MyFile.pdf?dl=1
