Send JSON from HTTPS to HTTP - json

Question

I use Request solution for ajax-request, but I get an error:
reqwest.min.js:6 Mixed Content: The page at 'https://...' was loaded
over HTTPS, but requested an insecure XMLHttpRequest endpoint
'http://...'. This request has been blocked; the content must be
served over HTTPS.
Server-side code (i'm using wordpress plugin for this):
add_action('wp_ajax_nopriv_wpse144893_search', 'wpse144893_search_data'); // allow logged out users
add_action('wp_ajax_wpse144893_search', 'wpse144893_search_data'); // allow logged in users
function wpse144893_search_data(){
header('Content-type: application/json');
header('Access-Control-Allow-Origin: *');
$errors = array();
$data = array(
'status' => 'error',
'message' => '',
'result' => array()
);
if(!isset($_REQUEST['term']) || empty($_REQUEST['term']))
$errors[] = 'No search term given!';
if(!isset($_REQUEST['limit']) || empty($_REQUEST['limit']))
$limit = 10;
else
$limit = (int) $_REQUEST['limit'];
if(empty($errors)){
$term = sanitize_text_field($_REQUEST['term']);
// setup query data
$args = array(
'posts_per_page' => $limit,
's' => $term
);
$query = new WP_Query($args); // run query
$results = array();
if($query->have_posts()): while($query->have_posts()): $query->the_post();
$post_item = array(
'title' => get_the_title(),
'excerpt' => get_the_excerpt(),
'permalink' => get_permalink()
);
$results[] = $post_item;
endwhile;
$data['status'] = 'success';
$data['message'] = 'Results found!';
$data['result'] = $results;
else:
$errors[] = 'No post found!';
$data['message'] = $errors;
endif;
}
echo json_encode($data); // print json
die(); // kill the script
}
Client-side code (request plugin):
reqwest({
url: 'http://...'
, type: 'json'
, method: 'get'
, crossOrigin: true
, withCredentials: true
, error: function (err) { alert('1'); }
, success: function (resp) {
alert('2');
}
})
I tried use this header('Content-type: application/json');header('Access-Control-Allow-Origin: *'); (see in server code above) but it does not solve the problem.

Problem is solved by moving second server to HTTPS...
