dubbo rest protocol 调用第三方restful 不支持https

RestProtocol类doRefer的方法中不支持https调用
ResteasyWebTarget target = client.target("http://" + url.getHost() + ":" + url.getPort() + "/" + getContextPath(url));
return target.proxy(serviceType);

Start with the RestProtocol class and its doRefer method, especially the ResteasyWebTarget construction shown in the issue. Check how third-party REST calls are formed for HTTPS and verify that an HTTPS endpoint can be invoked successfully; done means the REST protocol no longer rejects or downgrades HTTPS calls.
