Nodejs 连接 mysql时报错 Error: Cannot enqueue Query after fatal error

解决办法，参考：https://github.com/chill117/express-mysql-session/issues/18

 

我们只需在实例化SessionStore的时候，配置useConnectionPooling: true。比如：

var sessionStore = new SessionStore({
    host: 'localhost',
    port: 3306,
    user: 'root',
    password: 'root',
    database: 'session',
    useConnectionPooling: true
});
