Route Express.JS Post参数

Question

我正在尝试将参数发布到express.js代码中......

[...]。post（function（req，res）{} 方法不起作用。

var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');

var index = 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', 'vash');

// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use(bodyParser.json());
app.use('/', index);
app.use('/users', users);
app.route('/a/:value').get(function (req, res) {
  res.render('index', {title: req.params.value});
});

//app.route('/').post doesn t work.. the ide (WebStorm) can't find the .post method

// 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 handler
app.use(function(err, req, res, next) {
  // set locals, only providing error in development
  res.locals.message = err.message;
  res.locals.error = req.app.get('env') === 'development' ? err : {};

  // render the error page
  res.status(err.status || 500);
  res.render('error');
});

module.exports = app;

IDE（Webstorm）说它无法找到.post()方法或功能 请你帮助我好吗 ？ 我正在使用node.js的最新版本。
