connect.cookieParser和connect.session [英] connect.cookieParser and connect.session

问题描述

我是刚接触框架的人。我想使用cookieParser（）和会话管理。请更正下面的代码及其为什么会显示此错误。

I am new to connect framework. I want to use cookieParser() and session management. Please correct the below code and why it shown this error.

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);

显示错误：

    .use(connect.cookieParser())
                 ^

推荐答案

版本2.21.0（2014-06-20）自连接他们已弃用的cookie解析器集成（ https://github.com/senchalabs/connect /blob/master/History.md ），则应单独安装：

Since version 2.21.0 (2014-06-20) of Connect they deprecated cookie-parser integration (https://github.com/senchalabs/connect/blob/master/History.md) and you should install it separately:

npm install cookie-parser --save

然后按如下所示使用它：

Then use it like shown below:

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