Looking at the test case I think the issue is that I set CURLOPT_POST and
provide neither CURLOPT_POSTFIELDS nor a read function. If the API contract
says I have to do one or the other, fair enough - but should Curl survive if
I don't?
Okay but as a POST request implies a request body, where do you provide said
body?
Without CURLOPT_POSTFIELDS (and *with* CURLOPT_POST set), libcurl only offers
one other way to provide the request body and that is the read callback. If
you don't set it, libcurl has a default read function that does an fread() by
stdin by default.
What did you expect would happen? A zero byte body?
In my mind, CURLOPT_POST explains that you *either* use CURLOPT_POSTFIELDS or
a read callback and that there's no third option, but I'm certainly open for
that we need to extend or clarify the docs somewhere!
