帶有connect-mysql-session的Expressjs

Question

我正在使用expressjs的connect-mysql-session模塊。對於每個請求給服務器，我得到這個：

Express server listening on port 3000 in development mode

爲什麼這樣做呢？

而且我還爲每個請求設置了約8個Cookie（connect.sid），我認爲它爲每個資產likje js，css和圖像設置。爲什麼它被設置了這麼多次？它是否支持？

繼承人我的配置：

app.set('views', __dirname + '/../views'); 
app.set('view engine', 'html'); 
app.register('.html', require('ejs')); 
app.use(express.bodyParser()); 
app.use(expressValidator); 
app.use(express.methodOverride()); 
app.use(express.cookieParser()); 
app.use(express.session({ 
store: new MySQLSessionStore("test_db", "root", "root"), 
    secret: 'cat' 
})); 
app.use(app.router); 
app.use(express.csrf()); 
app.use(express.static(__dirname + '/../public'));

我不是100％地肯定這一點，但我覺得你應該把靜態中間件更之上。關鍵是要有上面的靜態中間件，因爲這不需要會話，cookie和其他中間件，就像這樣：

app.set('views', __dirname + '/../views'); 
app.set('view engine', 'html'); 
app.register('.html', require('ejs')); 
app.use(express.static(__dirname + '/../public')); 
app.use(express.bodyParser()); 
app.use(expressValidator); 
app.use(express.methodOverride()); 
app.use(express.cookieParser()); 
app.use(express.session({ 
store: new MySQLSessionStore("test_db", "root", "root"), 
    secret: 'cat' 
})); 
app.use(app.router); 
app.use(express.csrf());
