我如何访问使用express的变量设置app.set()为例如

app.set('view engine','jade');
app.set('jsDirectory',/js/');

从指南,我明白我可以访问相同的使用app.get(<key>),但这是输出console.log(app.get('view engine')).

{ router:
   { app:
      { stack: [Object],
        domain: null,
        _events: [Object],
        _maxListeners: 10,
        _connections: 0,
        connections: [Getter/Setter],
        allowHalfOpen: true,
        _handle: null,
        httpAllowHalfOpen: false,
        cache: {},
        settings: [Object],
        redirects: {},
        isCallbacks: {},
        _locals: [Object],
        dynamicViewHelpers: {},
        errorHandlers: [],
        route: '/',
        routes: [Circular],
        router: [Getter],
        root: 'C:\\Users\\Shahal\\Works\\App',
        models: {},
        extensions: {},
        disconnectSchemas: [Function: disconnectSchemas],
        passport: [Object] },
     routes: {},
     params: {},
     _params: [],
     middleware: [Function] } }
