我想从winston logger.js中的配置文件(config/default.json等(中提取主机和端口。
但我找不到方法，可以吗？
config/default.json
{
"host": "localhost",
"port": 3030,
"public": "../public/",
"paginate": {
"default": 10,
"max": 50
},
}
winston-logger.js
// How to get app.settings in this file?
const logger = expressWinston.logger({
...
})
module.exports = logger
app.js
const winstonLogger = require('./winston-logger');
app.use(winstonLogger)
更新
当我按照注释的建议设置winston-logger.js时，
出现错误。
TypeError: app.get is not a function
winston-logger.js
// How to get app.settings in this file?
const app = require('./app');
console.log(app.get('host'), app.get('port'));
const logger = expressWinston.logger({
...
})
module.exports = logger
app.js
const path = require('path');
const favicon = require('serve-favicon');
const compress = require('compression');
const helmet = require('helmet');
const cors = require('cors');
const logger = require('./logger');
const winstonLogger = require('./winston-logger');
const feathers = require('@feathersjs/feathers');
const configuration = require('@feathersjs/configuration');
const express = require('@feathersjs/express');
const socketio = require('@feathersjs/socketio');
const middleware = require('./middleware');
const services = require('./services');
const appHooks = require('./app.hooks');
const channels = require('./channels');
const authentication = require('./authentication');
const sequelize = require('./sequelize');
const app = express(feathers());
// Load app configuration
app.configure(configuration());
// Enable security, CORS, compression, favicon and body parsing
app.use(helmet({
contentSecurityPolicy: false
}));
app.use(cors());
app.use(compress());
app.use(express.json({ limit: '10mb' }));
app.use(express.urlencoded({ limit: '10mb', extended: true }));
app.use(favicon(path.join(app.get('public'), 'favicon.ico')));
// Host the public folder
app.use('/', express.static(app.get('public')));
// Set-Up http request logger
app.use(winstonLogger)
// Set up Plugins and providers
app.configure(express.rest());
app.configure(socketio());
app.configure(sequelize);
// Configure other middleware (see `middleware/index.js`)
app.configure(middleware);
app.configure(authentication);
// Set up our services (see `services/index.js`)
app.configure(services);
// Set up event channels (see channels.js)
app.configure(channels);
// Configure a middleware for 404s and the error handler
app.use(express.notFound());
app.use(express.errorHandler({ logger }));
app.hooks(appHooks);
module.exports = app;
这些值可通过@feathersjs/configuration通过app.get获得(另请参阅示例(：
// How to get app.settings in this file?
const app = require('./app');
console.log(app.get('host'), app.get('port'));
const logger = expressWinston.logger({
...
})
module.exports = logger
