Welcome to the forum.

Please become accustomed to provide decent context info of your problem.
It is always helpful to support a request with system info like OS and shell, related environment (variables, options), preferred tools, adequate (representative) sample input and desired output data and the logics connecting the two, and, if existent, system (error) messages verbatim, to avoid ambiguities and keep people from guessing.

I'm pretty sure you won't "curl with these variables:", so please provide complete commands so people don't need to guess what you're doing or want to do. To read, expand, and use data from files, try

Code:

while read A B C D E; do echo "{ \"nodename\": \"$A\", \"ipaddress\": \"$B\", \"poolname\": \"$C\", \"port\": \"$D\", \"loadbalancer\" : \"$E\" }"; done < input_file.txt
{ "nodename": "server001", "ipaddress": "10.10.10.01", "poolname": "serverpool1", "port": "80", "loadbalancer" : "loadbalancer01" }
{ "nodename": "server002", "ipaddress": "10.10.10.02", "poolname": "serverpool1", "port": "80", "loadbalancer" : "loadbalancer01" }
{ "nodename": "server003", "ipaddress": "10.10.10.03", "poolname": "serverpool1", "port": "80", "loadbalancer" : "loadbalancer01" }

	 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

	 /* use a GET to fetch this */
	 curl_easy_setopt(curl, CURLOPT_HTTPGET, 1L);

	 /* Perform the request */
	 curl_easy_perform(curl);
       }
