JSON API Auth Plugin not working for Add Comment

This question is not related to this plugin but here’s the answer.

To post comment the way you want it, use following post_comment method, you can add this in respond.php file. This can’t be done with the JSON API respond controller submit_comment method.

function post_comment(){
	   global $json_api;

 if ( !$json_api->query->post_id ) {
      $json_api->error("No post specified. Include 'post_id' var in your request.");
    } 

if ( !$json_api->query->user_id )  {
      $json_api->error("Please include 'user_id' var in your request.");
    }

 if (!$json_api->query->content ) {
      $json_api->error("Please include 'content' var in your request.");
    }

	$user_info = get_userdata( $json_api->query->user_id );

	 $time = current_time('mysql');
	 $agent = $_SERVER['HTTP_USER_AGENT'];
	 $ip=$_SERVER['REMOTE_ADDR'];

$data = array(
    'comment_post_ID' => $json_api->query->post_id,
    'comment_author' => $user_info->user_login,
    'comment_author_email' => $user_info->user_email,
    'comment_author_url' => $user_info->user_url,
    'comment_content' => $json_api->query->content,
    'comment_type' => '',
    'comment_parent' => 0,
    'user_id' => $user_info->ID,
    'comment_author_IP' =>  $ip,
    'comment_agent' => $agent,
    'comment_date' => $time,
    'comment_approved' => 1,
);

//print_r($data);

$comment_id = wp_insert_comment($data);
return array(
			"status" => 'ok',
            "comment_id" => $comment_id
             );
  }
