How vuex stores data in store

problem description

I just started using the vue write function, and the data in loginStore is empty. I wonder if I can save the userdata in api.js into store!

related codes

loginStore.js

import {
  login
} from "../Services/api.js";
import {
  to
} from "await-to-js";
import {
  resolve
} from "path";
export default {
  state: {
    username: "admin",
    password: "123456",
    userdata: ""
  },
  mutations: {
    ADD_LOGIN_USER_INFO(
      state, data
    ) { //sessionStorage
      sessionStorage.setItem("userdata", JSON.stringify(data)); 
      state.userdata = data;
    },
  },
  actions: {
    async login({
      state,
      commit,
    }) {//
      let data = await to(
        login.handleLogin({
          userCode: state.username,
          userPassword: state.password
        })
      );
      if (state.username == null || state.username == "" || state.username.replace(/(^\s*)|(\s*$)/g, "") == "") {
        alert("");
        return;
      } else if (state.password == null || state.password == "" || state.password.replace(/(^\s*)|(\s*$)/g, "") == "") {
        alert("");
        return;
      }
      //,return,
      console.log(JSON.stringify(data));
      commit("ADD_LOGIN_USER_INFO", data); 
    }
  },
  getters: {

  }
}

loginStore the data typed here is [null,null]

api.js

import axios from "axios";
import Qs from "qs";
import store from "../store/loginStore"
let  userdata;
export  const login = {
  //
  async handleLogin() {
    let postData = Qs.stringify({
      userCode: store.state.username,
      userPassword: store.state.password
    });
    return axios({
      method: "post",
      url: "/login/loginVerify",
      data: postData
    }).then((res) => {
      if (res.data.code == 1) {
        userdata = res.data.result;
        console.log(userdata) //
        alert("")
      } else {
        alert("!")
        return;
      }
    }).catch(function (error) {
      console.log(error);
    });
  },
}

result

I think it"s worth it in data, so you don"t have to do userdata in api.js
