处理并保留node.jsexpress会话

处理并保留node.js / express会话

在

fs.mkdir

您删除会话后，听起来很异国。（我发现了您的其他问题）

但是回到问题，这里有一些代码片段，您可以使用会话（redis）。

var express = require('express')  , fs = require('fs')  , http = require('http')  , RedisStore = require('connect-redis')(express)  , sessionStore = new RedisStore()  , app = express()  ;app.configure(function(){  app.set('port', 3000);  app.use(express.bodyParser());  app.use(express.methodOverride());  app.use(express.cookieParser('secret'));  app.use(express.session({    store: sessionStore  }));  app.use(express.static(__dirname + '/public'));  app.use(express.errorHandler({ dumpExceptions: true, showStack: true }));});app.get( '/', function(req, res){  res.setHeader("Content-Type", "text/html");  console.log( req.session );  console.log( '------------------------' );  res.end( 'root' );});app.get( '/dir/:id', function(req, res){  console.log( req.session );  console.log( '------------------------' );  fs.mkdir( req.params.id );  if ( req.session.dirs === undefined )    req.session.dirs = [];  req.session.dirs.push( req.params.id );  console.log( req.session );  console.log( '------------------------' );  res.setHeader("Content-Type", "text/html");  res.end( 'dir' );});server = http.createServer(app).listen(3000);

您应该阅读express的文档，并浏览express
的示例
