我使用express4写的app.js
var express = require(‘express’);
var path = require(‘path’);
var favicon = require(‘static-favicon’);
var logger = require(‘morgan’);
var cookieParser = require(‘cookie-parser’);
var bodyParser = require(‘body-parser’);
//var partials = require(‘express-partials’);用jade模板，不能使用这个中间件
var session = require(‘express-session’);
var MongoStore = require(‘connect-mongo’)(session);
var settings = require(‘./settings’);
var flash = require(‘connect-flash’);
var routes = require(‘./routes/index’);
var users = require(‘./routes/users’);
var app = express();
// view engine setup
app.set('views’, path.join(__dirname, ‘views’));
app.set('view engine’, ‘jade’);
//app.use(partials());
app.use(favicon());
app.use(logger(‘dev’));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded());
//cookie解析的中间件
app.use(cookieParser());
app.use(express.static(path.join(__dirname, ‘public’)));
app.use(flash());
//提供session支持
app.use(session({
secret: settings.cookieSecret,
store: new MongoStore({
db: settings.db,
})
}));
app.use(function(req, res, next){
console.log(“app.usr local”);
res.locals.user = req.session.user;
res.locals.post = req.session.post;
var error = req.flash(‘error’);
res.locals.error = error.length ? error : null;
var success = req.flash(‘success’);
res.locals.success = success.length ? success : null;
next();
});
app.use('/’, routes);
app.use('/users’, users);
/// catch 404 and forward to error handler
app.use(function(req, res, next) {
var err = new Error(‘Not Found’);
err.status = 404;
next(err);
});
/// error handlers
// development error handler
// will print stacktrace
if (app.get(‘env’) === ‘development’) {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error’, {
message: err.message,
error: err
});
});
}
// proction error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error’, {
message: err.message,
error: {}
});
});
mole.exports = app;
