当我使用app.locals时,我得到了未定义。我只是使用app.local作为配置变量。我如何在listen(PORT)中使用它
app.js
app.locals = {
socket_io_host: 'http://localhost:3001',
socket_io_port: "3001",
};
路由/ index.js
var express = require('express');
var router = express.Router();
var server = require('http').Server(express).listen(app.locals.socket_io_port);
var io = require('socket.io')(server);
console.log("["+app.locals.socket_io_port+"]");
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express',point1: point1,point2: point2 });
});

您必须要求:
app.js:
module.exports = {
socket_io_host: 'http://localhost:3001',
socket_io_port: "3001",
}
index.js:
// put as the first line
var app = require('./app');
