}

Improved point

HttpsURLConnection connect =(HttpsURLConnection)url.openConnection();

  connect.setRequestMethod("GET");//请求方式

  connect.setRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/79.0.3945.130 Safari/537.36");//设置属性

Access to resources but also by the openSteam () becomes getInputsteam ()
