捕获事件后可进行的

useMessage​

在响应事件（如消息被创建）时，发送消息。

src/response/**/*/res.ts
import { Text, useMessage } from 'alemonjs'
export const selects = onSelects(['message.create'])
export default onResponse(selects, (event, next) => {
  // 创建
  const [message] = useMessage(event)
  message.send(format(Text('hello word !')))
})
src/response/**/*/res.ts
import { Text } from 'alemonjs'
export const selects = onSelects(['message.create'])
export default onResponse(selects, () => {
  return {
    // 即将要发送的数据
    data: format(Text('hello word !'))
  }
})

需要注意的是。虽然参数支持任何数量的forma参数。

但send会对数据保持单一消息原则。

即，不能合并在一起的数据，只会发送最近的一个。

如：多个Image。只会发送第一张。而多个Text则会合并。Image+Text会一起发送。（受限于平台）

如果想自由发送图片和文字,并配合按钮使用。需要使用 Markdown。

useMention​

解析得到被提及的数据

response/**/*/res.ts
import { useMention } from 'alemonjs'
export const selects = onSelects(['message.create'])
export default onResponse(selects, async (event, next) => {
  const [mention] = useMention(event)
  // 查找用户类型的 @ 提及，且不是 bot
  const user = await mention.findOne()
  if (!user) {
    return // 未找到用户Id
  }

  console.log('User:', user)

  // 处理被AT的用户...
})

useSubscribe​

订阅模式，在某个事件周期中进行观察

response/**/*/res.ts
import { Text, useMessage, useSubscribe } from 'alemonjs'
export const regular = /^(#|\/)?login$/
export const selects = onSelects([
  'message.create',
  'private.message.create'
])
export default onResponse(selects, event => {
  const [message] = useMessage(event)
  const [subscribe] = useSubscribe(event, selects)

  message.send(format(Text('请输入密码'), Text('123456')))

  // 订阅 res 挂载之前的
  const sub = subscribe.mount(
    (event, next) => {
      // 创建
      const [message] = useMessage(event)
      // 获取文本
      const text = event.MessageText
      // 检查
      if (text === '123456') {
        message.send(format(Text('密码正确')))
        clearTimeout(timeout)
      } else if (text == '/close') {
        message.send(format(Text('取消登录')))
        clearTimeout(timeout)
      } else {
        message.send(format(Text('密码不正确')))
        // 继续
        next()
      }
    },
    ['UserId']
  )

  const timeout = setTimeout(() => {
    // 取消订阅
    subscribe.cancel(sub)
    // 发送消息
    message.send(format(Text('登录超时')))
  }, 1000 * 10)
})
response/**/*/res.ts
import { useSubscribe } from 'alemonjs'

export const selects = onSelects(['message.create'])

const res$1 = onResponse(selects, (event, next) => {
  // 创建
})

const res$2 = onResponse(selects, (event, next) => {
  // 响应之前
})

const res$3 = onResponse(selects, (event, next) => {
  // 响应之后
})

export default onResponse(selects, (event, next) => {
  const [subscribe] = useSubscribe(event, selects)
  subscribe.create(res$1.current, [])
  subscribe.mount(res$2.current, [])
  subscribe.unmount(res$3.current, [])
})
middleware/**/*/res.ts
import { Text, useMessage, useSubscribe } from 'alemonjs'
export const regular = /^(#|\/)?login$/
export const selects = onSelects([
  'message.create',
  'private.message.create'
])
export default onResponse(selects, event => {
  const [message] = useMessage(event)
  const [subscribe] = useSubscribe(event, selects)

  message.send(format(Text('请输入密码'), Text('123456')))

  // 订阅 res 挂载之前的
  const sub = subscribe.mount(
    (event, next) => {
      // 创建
      const [message] = useMessage(event)
      // 获取文本
      const text = event.MessageText
      // 检查
      if (text === '123456') {
        message.send(format(Text('密码正确')))
        clearTimeout(timeout)
      } else if (text == '/close') {
        message.send(format(Text('取消登录')))
        clearTimeout(timeout)
      } else {
        message.send(format(Text('密码不正确')))
        // 继续
        next()
      }
    },
    ['UserId']
  )

  const timeout = setTimeout(() => {
    // 取消订阅
    subscribe.cancel(sub)
    // 发送消息
    message.send(format(Text('登录超时')))
  }, 1000 * 10)
})

useState​

声明res/mw的状态,可用于管理是否启用

命名规则 子应用名:response:文件夹1:文件夹2...

如默认main为： main:response:login

注意

响应文件夹由apps（旧版本）命名为response

response/**/*/res.ts
import { Text, useSends, useState } from 'alemonjs'
export const regular = /^(#|\/)?close:/
export const selects = onSelects(['message.create'])
export default onResponse(selects, (event, next) => {
  //   /close:login
  const name = event.MessageText.replace(regular, '')
  const [state, setState] = useState(name)
  if (state) {
    next()
    return
  }
  setState(false)
  const [send] = useSends(event)
  send(format(Text('关闭成功')))
  return
})

可以在任意地方订阅状态的更改。

response/**/*/res.ts
import { onState, unState } from 'alemonjs'

const key = 'main:response:login'

const state = (val: boolean) => {
  // 订阅 key 的状态变化
}

onState(key, state)
unState(key, state)
