See more Dropbox Examples

Get a temporary link to stream content of a file. This link will expire in four hours and afterwards you will get 410 Gone. Lua

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

local http = chilkat.Http.new()

-- 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\"}"

-- The following JSON is sent in the request body.

-- {
