Notice: when we want to use `this` inside a listener, we must use the traditional `function(this) {}` instead of fat arrow `() => {}` to get `Sayable``this` inside.
```diff
- wechaty.on('login', user => { // 1. fat arrow function `() => {}` will not get `Sayable` this
+ wechaty.on('login', function(this, user) { // 2. traditional `function(this, ...) {}` will get the right `Sayable` `this`
- wechaty.on('login', user => { // 1. do not use fat arrow function if you want a `Sayable` `this`
+ wechaty.on('login', function(this, user) { // 2. use traditional `function(this, ...) {}` instead
this.say(`${user.name()} logined`)
})
``
```
which means there will be a `this.say()` method inside listener call, you can use it sending message to `filehelper`, just for logging / reporting / any usage for your convienience
