Thank you all for your help, I have it working, along with an extra line after header it also need Host for authentication and Content-Length for the message to be properly parsed.
"POST /emp/ HTTP/1.1\r\nHost: 192.168.16.10\r\nAuthorization: Basic YWRtaW46cGFzcw==\r\nContent-Type: application/json\r\nContent-Length: 1471\r\n\r\n%s\r\n" -----Original Message----- From: curl-library [mailto:curl-library-boun...@cool.haxx.se] On Behalf Of Daniel F via curl-library Sent: Tuesday, July 20, 2021 3:22 AM To: libcurl development <curl-library@cool.haxx.se> Cc: dan...@poradnik-webmastera.com Subject: Re: How to authenticate when using “CURLOPT_CONNECT_ONLY” so I can use non-blocking curl_easy_send() and curl_easy_recv() You must add extra empty line after headers, to tell server where they end and content starts.
