Upload a file using c++ via curl

:open_mouth: No! Just opposite. Just some more work would be needed, because of missing SDK ready. And Between: again libcurl is C library, not C++, that's why ifstream object can't be 'stream' (i.e. cast) directly. :wink: Be careful.

C code still works on C++, so any C code that can do what I am intending to do would be useful to me.

And I need to know that 'some more work' so I can do it:grin::grin:

Yes, of course. But there are some differences you have to be aware! In C++ you can use overload functions (for example), but not in C. :wink: Again, just be careful.

I have some basic knowledge of C and I am aware of the C limitations

I really thank you Здравко  for investing so much time trying to help me. I really appreciate it.

I will keep looking for a way to do what I want.
Hopefully Greg-DB will come with a solution

You're on the right track. That is, you can upload files to Dropbox using HTTPS requests to /2/files/upload, and you have the basic code to do so already. 

It sounds like you're currently working on how to get the data from the local file system though, which isn't specific to Dropbox, so I'm afraid I can't offer much specific help with that in particular, nor do I have a code sample for that in particular. (I'm also certainly not a C expert.) 

As I said, I will keep looking

Thank you for your time Greg-DB 

As for DropBox I will be expecting an official C++ SDK soon :grin::grin:

Edit: As a note I found  a repo on github, a dropbox api c++ library that on looks seems to do what I want but I haven't figure the whole code out and get it to work

Здравко Greg-DB  if you guys could check it out some time and try to figure the code out and hit me back that would be awsome nit only for me but for anyone that wants to do what I want to do

Just to be clear, I've sent this along as a feature request, but I can't promise if or when Dropbox would release an official C++ SDK for API v2. (I'm not currently of any such work on one.)

I know, I just hope Dropbox releases it not in a distant future

Hi hb_,

The code you find out seems pretty old (last update 6 years ago). Old Dropbox API is implemented there (currently deprecated, although available still). I'm not sure if there is schedule for this API support dropping. From other view point this is good example of Boost library usage (very powerful C++ library). I have no idea, in this context, why libcurl is still used (everything could be done using Boost only). Also this code could be used as good (not the best, but...) example of mixing C and C++ code. :wink: May be this could be used as start point for implementing Dropbox API v2. (at least some tips)

Good luck.

I just took a look at that third party libray, and I can confirm it does use the old Dropbox API v1. To clarify one point, Dropbox API v1 is already retired, and so it not available. Attempting Dropbox API v1 calls will fail.

  thank you guys for your insight, appreciate it

yeah Здравко  I have recently started using boost, as a matter of fact the reason I've been searching a way to use c++ to upload file to dropbox is that I have found out the way to search files recursively by their extension, so I thought of going in Disk D:\\ and uploading all the files with .jpg or .mp4 extensions.
I know what you're thinking, Dropbox application can even upload a whole folder but it is a lot more fun to do that with code, specially since I am C++ beginner.

Greg-DB ooh, thanks for this info, I will stop cracking my head with that library
