如何访问使用app.set（）在express js中设置的变量 [英] How to access variables set using app.set() in express js

问题描述

如何使用express的 app.set（）访问变量集，例如

How do i access the variables set using express's app.set() for e.g

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

从指南中，我明白我可以使用 app.get（< key>），但这是 console.log（app.get（'view engine'））的输出。

From the guide, i understand that i can access the same using app.get(<key>), but this is the output of 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] } }

推荐答案

可通过app.settings对象获得：

They become available through the app.settings object:

app.set('oneSetting', 'one');
app.set('twoSetting', 'two');
app.set('view engine','jade');

console.log(app.settings.oneSetting);
console.log(app.settings.twoSetting);
console.log(app.settings['view engine']);
