LoginView.vue

<template>
  <div class="box">
    <p>
      用户名：

    </p>
    <p>
      密码：

<script setup>
import {ref} from "vue";
import {useRouter} from "vue-router";
import {userInfoStore} from "@/stores/user.js";
import _axios from "@/plugins/axios.js";

const msg = ref({
  username: "",
  password: ""
})
const router = useRouter()
const store = userInfoStore()

const doLogin = function () {
  // 1、获取数据
  console.log(msg.value)
  // 2、发送网络请求
  _axios.get("/api/v1/course/category/free/?courseType=free").then((res) => {
    console.log(res.data)
  })
  // 3、本地存储用户信息（登录凭证）
  // localStorage.setItem("name", msg.value.username)
  let info = {id: 1, name: msg.value.username, token: "ddsafhsjdfkj"}
  store.doLogin(info)
  // 3、跳转到首页
