why is download api a post https request with null body?

[petal]

Hi, I noticed that the download api https://content.dropboxapi.com/2/files/download is a post https request, but required a null request body. And I can also download a file correctly with method "get". So I am confused why dropbox make rules like this? I does not think this way for a post request meet the rules of HTTP request.

The Dropbox API uses HTTPS for communication, but it is not a REST API and so does not follow the REST pattern you may be familiar with, for instance. You can find the documentation for the Dropbox API v2 request and response formats here. You may also be interested in these old blog posts about the original design of API v2.
