我是node.js
世界的新手。我正在尝试编写REST服务,但我遇到了会话管理问题。所以我创建了一个单独的应用程序,只是为了看看我是否可以让会话工作,但事实并非如此,这是代码。 req.session.username
始终未定义:
var express = require('express');
var url = require('url');
var app = express()
app.use(express.cookieParser('Hiren'))
app.use(express.session({ secret: 'HirenAdesara' }))
app.use(express.bodyParser())
app.use(app.router)
//Sniff HTTP
app.all('*', function(req, res, next) {
//Check for Authentication
console.log(req.session)
if ((!(/^\/auth/g.test(req.url))) && (!req.session)) {
console.log('in app.all: Unauthorized')
res.send(401)
}
else
{
return next()
}
})
app.post('/auth', function(req, res) {
var query = req.body
console.log('Query' + JSON.stringify(query))
username = query.username;
password = query.password;
if(username == 'Hiren' && password == 'Adesara')
{
req.session.username = 'Hiren';
console.log('New Session Created..')
res.send(200)
}
else
{
console.log('New session could not be created.')
res.send(401)
}
})
app.get('/projects', function(req,res) {
console.log('inside projects' + req.session.username);
res.send(req.session.username); })
app.listen(2048)
console.log('Listening on port 2048...')
它不起作用,我不知道这里有什么问题。
答案 0 :(得分:3)
通过移动app.get('/'...)中的3行来加星:
var express = require('express');
var querystring = require('querystring');
var app = express()
app.use(express.cookieParser('Hiren')); // This line
app.use(express.session({ secret: 'HirenAdesara' })); // This line
app.use(express.bodyParser()); // This line
app.get('/', function(req, res){
res.send('hello from the root page');
})
// the rest of your code
