Expressjs 与 connect-mysql-session

Question

我正在使用带有 expressjs 的 connect-mysql-session 模块。对于对服务器的 每个 请求，我得到以下信息：

Express server listening on port 3000 in development mode

为什么要这样做？

我也为每个请求设置了大约 8 个 cookie (connect.sid)，我认为它是为每个资产设置的，如 js、css 和图像。为什么要设置这么多次？应该是吧？

这是我的配置：

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'));

问候

我对此不是 100% 确定，但我认为您应该将静态中间件放在首位。关键是要有上面的静态中间件，因为它不需要会话、cookie 和其他中间件，如下所示：

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());
