Java支持

使用方法

    from pyhocon import ConfigFactory
    conf = ConfigFactory.parse_file('samples/database.conf')
    host = conf.get_string('databases.mysql.host')
    same_host = conf.get('databases.mysql.host')
    same_host = conf['databases.mysql.host']
    same_host = conf['databases']['mysql.host']
    port = conf['databases.mysql.port']
    username = conf['databases']['mysql']['username']
    password = conf.get_config('databases')['mysql.password']
    password = conf.get('databases.mysql.password', 'default_password') #找不到key使用默认值

非阻塞WebServer，非Wsgi

    override fun onReceivedSslError(view:WebView?,  handler:SslErrorHandler,  error: SslError?) {
                    //handler.cancel(); 默认的处理方式，WebView变成空白页
                    handler.proceed();//接受证书
                    //handleMessage(Message msg); 其他处理
                }
