node.js - Node Express 模块抛出 'has no method urlencoded' 错误

Question

var express=require('express')
var app=express();

console.log("Encoded ",express.urlencoded());

app.use(express.urlencoded());

上面的代码抛出以下错误:

[user@localhost nodejs]$ node program.js

/home/user/Desktop/nodejs/program.js:41
console.log("Encoded ",express.urlencoded());
                               ^
TypeError: Object function createApplication() {
  var app = function(req, res, next) {
    app.handle(req, res, next);
  };

  mixin(app, proto);
  mixin(app, EventEmitter.prototype);

  app.request = { __proto__: req, app: app };
  app.response = { __proto__: res, app: app };
  app.init();
  return app;
} has no method 'urlencoded'

这里似乎有一个类似的问题 - express.js trouble with connect modules 但我已经使用此处列出的建议检查了express3.0.0 - Find the version of an installed npm package

我还阅读了此处的 Api 文档 - http://expressjs.com/api.html，它们列出了 urlencoded()

请帮忙。

我还想指出，我也尝试使用 bodyParser() 但也给出了相同的错误 has no method

快速指南有点过时了。

对于其他有同样问题的人，解决方案是将这些方法转移到新模块body-parser

示例代码

var express=require('express');
var app=express();
var bodyParser = require('body-parser');

app.use(bodyParser.urlencoded());
