import {defineStore} from 'pinia'
import {ref, computed} from "vue"
import axios from 'axios'

export const useChannelStore = defineStore('Channel', () => {
  // 定义state
  const channelList = ref([])

  // 定义actions
  const getChannelList = async () => {
    const resp = await axios.get('http://geek.itheima.net/v1_0/channels')
    console.log(resp);
    // 赋值给state
    channelList.value = resp.data.data.channels
  }

  return {
    channelList,
    getChannelList,
  }
})

app.vue

<script setup>
// 1. 导入store
const channelStore = useChannelStore();

</script>
<template>
  <button @click="channelStore.getChannelList()">获取新闻列表</button>
  <ul>
    <li v-for="item in channelStore.channelList" :key="item.id">
