Upload a file using c++ via curl

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.

Здравко I have spent some trying to figure the code out and I did, not everything though, but I couldn't apply it to my code. It looks like it is the hard way to do that

Greg-DB any clue?

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.

The same. In addition you can use CURLOPT_POSTFIELDSIZE (you can't rely on zero termination). :wink:

Good example could be foud here.

hb_ :grinning: :sunglasses: Yes definitely. You are trying to implement something like new SDK, in fact. :wink: That's why I proposed this on the thread! To be more easy, at least for future. May be an easier way would be take a look on some existing SDK (on language familiar to you) and reimplement what's there (at least needed parts).

Здравко so you are saying that currently there's no way to upload file from my computer to my dropbox account using c++ via curl?? :cry::cry:

: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
