Pinia中action使用方法详解

export const useUsers = defineStore('users',{
	state:()=>{
		userData:null
	},
	actions:{
		async registerUser(login,password){
			...
			this.userData = 1
		}
	}
})

<script setup>
	import { useUsers } from '...'
	const store = useUsers()
	store.registerUser()//可以直接调用

</script>

//新建一个测试仓库
import { defineStore } from 'pinia'
export const testStore = defineStore('test', {
    state() {
        return {
            count:1
        }
    },
    actions: {
        testOnAction(id) {
            this.count++
            console.log(this.count)
            return Promise.resolve('这是testOnAction返回的值')
        },
        testOnAction2(...args) {
            console.log(...args)
            return Promise.reject('这是testOnAction222错误返回的值')
        }

    }
})
//在setup的语法糖里
import { testStore } from '../../pinia/modules/test'
const myTestStore = testStore()

store.$onAction(({
  name,
  store,
  args,
  after,
  onError
})=>{
	if(name==='testOnAction'){
		after((reject)=>{
			//这里可以执行一些操作
		})
	}
	//onError钩子类似一个错误级中间件，当函数抛出promise的失败状态就会调用
  onError((error)=>{
    console.log(error)
  })
})
store.testOnAction(1)
store.testOnAction2(1,2,3,45)
