Example #1

static void handle_sum_call(struct ns_connection *nc, struct http_message *hm) {
  char n1[100], n2[100];

  /* Get form variables */

  ns_printf(nc, "%s", "HTTP/1.0 200 OK\n\n");
  ns_printf(nc, "{ \"result\": %lf }", strtod(n1, NULL) + strtod(n2, NULL));
}

Example #2

File: restful_server.c Project: csyangbinbin/cantk-runtime-v8

  /* Compute the result and send it back as a JSON object */
  result = strtod(n1, NULL) + strtod(n2, NULL);
  ns_printf_http_chunk(nc, "{ \"result\": %lf }", result);
