* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loHttp = CreateObject('Chilkat.Http')

* Implements the following CURL command:

* curl -X POST https://api.dropboxapi.com/2/files/get_temporary_link \
*     --header "Authorization: Bearer DROPBOX_ACCESS_TOKEN" \
*     --header "Content-Type: application/json" \
*     --data "{\"path\": \"/video.mp4\"}"
