I use a PHP server to manage Dropbox files for customers.
My server records the user's access token.
But When customers want to upload a file to theirs Dropbox,they must first upload file to my server,and my server use http(php curl) send file to Dropbox through Dropbox Api.
This raises some problem：
1:If C + + client use Dropbox API, they can upload files directly from the local,but use PHP server the file just can local->server->Dropbox,This results in a lower user experience and give the server tremendous pressure.
Is there any way for customers to upload files directly to Dropbox instead of PHP server get whole file and forward.
