Upload a file using c++ via curl

Hi, I was googling for a way to upload a file to any cloud storage using c++ and came across dropbox api. I found the code, so I did a copy and paste to try and see if it works. I entered the Access token and ran the code, the upload failed showing this error:

"Error in call to API function "files/upload": The given OAuth 2 access token is malformed."

I suspect the error could be related to this line of code:

curl_easy_setopt(curl, CURLOPT_URL, "https://content.dropboxapi.com/2/files/upload");

But I am new in this so I have no idea how to solve it.

    Hi hb_,

    Definitely the problem is not in cited code line. Did you set properly CURLOPT_XOAUTH2_BEARER parameter? :thinking:

    Hope this gives some direction. :wink:

      Здравко  Thank you. You were right, I guess this time I set CURLOPT_XOAUTH2_BEARER parameter properly so it gave another error:

      "Error in call to API function "files/upload": Must provide HTTP header "Authorization" or URL parameter "authorization"."

      I am searching to find out what this error could be about. 

      If you can help in any way I would much appreciate.

        hey Здравко  I think it worked

        However I came to find that the code does not do what I actually want, what it does is just creates a new file and write something you specify to it but I want to upload a local file from my computer to my dropbox account?

        Any idea how can I do that?
