Nodejs express 4.2 现在无法在路由文件中获取 表单post过来的值

请参考我的文章“使用express4.x版和Jade模板重写《nodejs开发指南》微博实例”， 网址：http://cnodejs.org/topic/53f23e198f44dfa35129c43b

app.js的代码：

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 }); }); }

// production 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: {} }); }); module.exports = app; index.js代码
