c++ send request to API on webserver then receive json array response?

I'm wondering the most simple way to send a request to a API on my server then receive the API's response (json array) wihtout using any libraries. I've tried using libs like cURL & boost without any luck which is the reason i want to stay away from them. I've searched for many days for a answer and have not been able to find anything, which is why i've resorted to coming to the stack overflow community!

Even though the question is about not using a library I 'am taking this opportunity to show how easy it is to use a library than the user thinks.

Its better to use pre-built libraries and stop reinventing the wheel. You can use curlcpp library. Its a wrapper for libcurl. Using this library HTTP requests can be made easily. Learning curve is also less and it provides C++ style access which makes it more comfortable to work with.

The following code is taken from their gitHub page - https://github.com/JosephP91/curlcpp

It makes a simple GET request to Google and retrieves the HTML response. You can use this example to hit apis too.

#include "curl_easy.h"
#include "curl_exception.h"

using curl::curl_easy;
using curl::curl_easy_exception;
using curl::curlcpp_traceback;

int main(int argc, const char **argv) {
    curl_easy easy;
    // Add some option to the curl_easy object.
    easy.add<CURLOPT_URL>("http://www.google.it");
    easy.add<CURLOPT_FOLLOWLOCATION>(1L);
    try {
        // Execute the request.
        easy.perform();
    } catch (curl_easy_exception error) {
        // If you want to get the entire error stack we can do:
        curlcpp_traceback errors = error.get_traceback();
        // Otherwise we could print the stack like this:
        error.print_traceback();
        // Note that the printing the stack will erase it
    }
    return 0;
}
