vuex—actions

store.js

import Vue from "vue"
import Vuex from "vuex"
import { Login } from "@/api/login"
Vue.use(Vuex)

export default new Vuex.Store({
state:{
},
getters:{
},
mutations:{
},
actions:{
    login(context, requestData) { //参数一：context  参数二：传的参数
	return new Promise((resolve, reject) => {    //new Promise({    }) resolve,reject分别是两个函数
	       //接口
		Login(requestData).then(response => {  
			resolve(response)    //异步成功时调用resolve（）函数，并将请求结果 response 返回出去。
		}).catch(error => {
			reject(error)
		})
	})
}

})

Login.vue vue3.0语法

const login = () => {
      const requestData = {
        username:ruleForm.username,
        password:sha1(ruleForm.password),
        code:ruleForm.code
      }
  
      
      root.$store.dispatch("login",requestData).then(response => {
        console.log(response);
        root.$router.push("/console")
      })

    }
