connect.cookieParser和connect.session

Question

我是连接框架的新手。我想使用cookieParser()和会话管理。请更正以下代码以及显示此错误的原因。

var connect = require("connect");
var app = connect();
connect()
    .use(connect.cookieParser())
    .use(connect.session({ secret: 'some secret text', cookie: { maxAge:       30000}}))
    .use(function(req, res) {
        var sess = req.session,
        url = req.url.split("/");

    if (url[1] == "name" && url[2]) {
        sess.name = url[2];
        res.end("name saved: " + url[2]);
    } else if (sess.name) {
        res.write("session-stored name: " + sess.name);    
        res.end("stored for another: " + (sess.cookie.maxAge / 1000) +seconds");
    } else {
        res.end("no stored name; go to /name/{name} to save a name");
    }
}).listen(3000);

下面是显示的错误：

C:\Users\Sagar\workspace\Node_connect\public\session.js:5
    .use(connect.cookieParser())
                 ^
TypeError: undefined is not a function

Answer 1

var express = require('express') var cookieParser =require(‘cookie解析器’)

var app = express() app.use(cookieParser())

参考：https://www.npmjs.com/package/cookie-parser

Answer 2

从Connect的2.21.0 (2014-06-20)版本开始，他们就弃用了cookie解析器集成(https://github.com/senchalabs/connect/blob/master/History.md)，你应该单独安装它：

npm install cookie-parser --save

然后按如下所示使用：

var connect = require('connect'),
        cookieParser = require('cookie-parser');
var app = connect()
    .use(cookieParser())
    .use(...)
