I don’t like to import certificates, so i cannot use httpuritype for HTTPS pages and I decided to create package which will work with https as http.
It was pretty easy with java stored procedures 
github/XT_HTTP
java source: xt_http.jsp
create or replace and compile java source named xt_http as
package org.orasql.xt_http;
import javax.net.ssl.HttpsURLConnection;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.HttpURLConnection;
import java.sql.Connection;
import oracle.jdbc.driver.*;
import oracle.sql.CLOB;
public class XT_HTTP {
/**
* Function getPage
* @param String Page URL
* @return String
*/
public static CLOB getPage(java.lang.String sURL)
throws java.sql.SQLException
{
OracleDriver driver = new OracleDriver();
Connection conn = driver.defaultConnection();
CLOB result = CLOB.createTemporary(conn, false, CLOB.DURATION_CALL);
result.setString(1," ");
try {
URL url = new URL(sURL);
HttpURLConnection con = (HttpURLConnection)url.openConnection();
//HttpsURLConnection con = (HttpsURLConnection)url.openConnection();
if(con!=null){
BufferedReader br =
new BufferedReader(
new InputStreamReader(con.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null){
sb.append(line);
}
br.close();
result.setString(1,sb.toString());
}
} catch (MalformedURLException e) {
result.setString(1, e.getMessage());
} catch (IOException e) {
result.setString(1, e.getMessage());
}
return result;
}
public static java.lang.String getString(java.lang.String sURL) {
String result="";
try {
URL url = new URL(sURL);
HttpURLConnection con = (HttpURLConnection)url.openConnection();
if(con!=null){
BufferedReader br =
new BufferedReader(
new InputStreamReader(con.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null){
sb.append(line);
}
br.close();
result = sb.toString().substring(0,3999);
}
} catch (MalformedURLException e) {
return e.getMessage();
} catch (IOException e) {
return e.getMessage();
}
return result;
}
}

package xt_http
create or replace package XT_HTTP is
/**
* Get page as CLOB
*/
function get_page(pURL varchar2)
return clob
IS LANGUAGE JAVA
name 'org.orasql.xt_http.XT_HTTP.getPage(java.lang.String) return oracle.sql.CLOB';
/**
* Get page as varchar2(max=4000 chars)
*/
function get_string(pURL varchar2)
return varchar2
IS LANGUAGE JAVA
name 'org.orasql.xt_http.XT_HTTP.getString(java.lang.String) return java.lang.String';
end XT_HTTP;

We have to grant connection permissions:
dbms_java.grant_permission( grantee => 'XTENDER' -- username , permission_type => 'SYS:java.net.SocketPermission' -- connection permission , permission_name => 'ya.ru:443' -- connection address and port , permission_action => 'connect,resolve' -- types );
And now we can easily get any page:
USAGE example:
declare
c clob;
s varchar2(8000);
begin
--- Through HTTPS as CLOB:
c:=xt_http.get_page('https://google.com');
--- Through HTTP as CLOB
c:=xt_http.get_page('http://ya.ru');
--- Through HTTPS as varchar2:
s:=xt_http.get_string('https://google.com');
--- Through HTTP as varchar2
s:=xt_http.get_string('http://ya.ru');
end;
