設定與使用

設定CouchDB Session Store

var connect = require('connect')    
  //step1. enable couchdb store    
  , ConnectCouchDB = require('connect-couchdb')(connect)    
  //step2. connection setting to couchdb
  , store = new ConnectCouchDB({
      name: 'session',
      host: "db_server_ip_address",
      port: 5984,
      username: 'username',
      password: 'password',
      ssl: false
    });
var app = express();
app.set('port', process.env.PORT || 3000);  
app.set('views', __dirname + '/views');  
app.set('view engine', 'jade');  
app.use(express.favicon());  
app.use(express.logger('dev'));  
app.use(express.bodyParser());  
//step3. setup session to specific store  
app.use(connect.cookieParser());  
app.use(connect.session({secret: 'YourSecretKey', store: store }));  
//step4. end of session setting  
app.use(express.methodOverride());  
app.use(app.router);  
app.use(express.static(path.join(__dirname, 'public')));

使用session

使用session的部份，原則上與其他persistance的使用方式相同，都是針對req.session這個物件做操作..

//Sample of get session  
app.get('/session/:key', function(req, res){
    console.log(req.session);
    res.end(util.format('key:%s --> value:%s', 
           req.params.key, req.session[req.params.key]));  
});
//Sample of set session
app.get('/session/:key/:value', function(req, res){
    req.session[req.params.key] = req.params.value;
    res.end('OK');  
});
