使用Express-express时出错

Question

问题：当我尝试使用session = require（“express-session”）时，安装快速会话时出错，但我已经使用npm install express-session安装了它。 我收到的错误是：

vishal@rocker:~/clg/project1/node_modules/express$ nodejs server.js

Error: Most middleware (like session) is no longer bundled with Express and must be installed separately. Please see https://github.com/senchalabs/connect#middleware.

现在安装快速会话后，我的目录结构是

node_modules
   express
       server.js // file where i am using it

   express-session

Server.js

var express = require("express"),
http = require("http"),
session = require("express-session"),
login = require("./server/login"),
app;
app = express();

http.createServer(app).listen(3000);

// set up a static file directory to use for default routing
app.use(express.static(__dirname+"/client"));

// set up express session to create session when user successfully        login
app.use(express.session({secret: '123456'}));

// set up our routes
// for user login
app.get("/login", function (req, res) {

var result = login.validate(req,res);
if(result){
    req.session.username="admin";
    res.send("successfully logged in");
}
else{

    res.append("error","Authentication Failed");
    res.sendFile(__dirname+"/client/index.html");
}

});

app.get("/goodbye", function (req, res) {
res.send("Goodbye World!");
});

我的新package.json

{
"name": "askr",
"version": "0.0.1",
"description": "Class project for 473",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "BSD-2-Clause",
"dependencies": {
"express-session": "~1.10.3",
"express": "~4.12.2"
}
}

express.session是直接折旧使用会话 。 如果在使用其他模块时遇到此错误，请确保已正确提及方法名称。
