You must add extra empty line after headers, to tell server where they
end and content starts. So you should send this:
"POST /emp/ HTTP/1.1\r\nAuthorization: Basic
YWRtaW46cGFzcw==\r\nContent-Type: application/json\r\n\r\n%s"

Before coming here I realized curl_easy_setopt has no effect setting
username and password so I tried to send it as part of post message
using curl_easy_send() as below but I am not receiving any response
back from server making me believe authentication did not go properly
and wondering what is the correct way of doing it.

You have literally told curl to connect and do nothing else. BasicAuth
is a part of HTTP protocol and done via HTTP headers which will not be
send with CURLOPT_CONNECT_ONLY. If you want to continue using
CURLOPT_CONNECT_ONLY, you'll have to do the HTTP part yourself.

SUBJECT: How to authenticate when using “CURLOPT_CONNECT_ONLY” so
I can use non-blocking curl_easy_send() and curl_easy_recv()
Hello there!, I am using libcurl to interface with over the shelf http
server box and having issue with authentication while using
“CURLOPT_CONNECT_ONLY” option to be able to use curl_easy_send()
and curl_easy_recv(), so my question is:
HOW TO (BASIC) AUTHENTICATE WHEN USING “CURLOPT_CONNECT_ONLY” SO I
CAN USE NON-BLOCKING CURL_EASY_SEND() AND CURL_EASY_RECV() ?
To give some background, I am able to authenticate and able to work
with the box with the blocked call ( without CURLOPT_CONNECT_ONLY
option) with no control over the curl connection. The problem is,
since the response from the box is a stream of data there is no way
for me to stop the stream and send an another request. So from the
documentation I figured out “CURLOPT_CONNECT_ONLY” is the way to
go, and using the socket handle I can manage the communication to the
box but after adding “CURLOPT_CONNECT_ONLY” option, I am not
receiving the data stream as expected, I guess my request went through
as there are no errors thrown, but looking closely I did not see
authentication happening – I assume that is the problem, I am not
doing anything fancy here just basic authentication only. Searched the
web but could not get an answer and I am stuck. What am I missing
here, does this option go in tandem with some other option I could not
figure out or is there a different approach to authenticate while
using this option.
Below is the verbose logs I captured with and without the option and
very much appreciate your help.
