1.安装axios

npm install axios --save

2.在main.js中引入

import { createApp } from 'vue'
import axios from 'axios'
import VueAxios from 'vue-axios'
const app = createApp(App)
app.config.globalProperties.$http = axios;
app.use(VueAxios, axios)

3.在根目录下的public文件夹data文件夹下新建一个userlist.json文件内容如下

{
    "data":{
        "sucess":200,
        "userList":[
            {
                "success":200,
                "name":"王三",
                "key":0,
                "age":21,
                "address":"海珠区琶洲会展中心"
            },
            {
                "success":200,
                "name":"李五",
                "key":1,
                "age":32,
                "address":"海珠区花城大道北109号"
            },
            {
                "success":200,
                "name":"嘎子哥",
                "key":2,
                "age":37,
                "address":"深圳市宝安区宝钢大道999号"
            },
            {
                "success":200,
                "name":"红豆",
                "key":3,
                "age":24,
                "address":"阳江市小岗村101号"
            },
            {
                "success":200,
                "name":"大娟",
                "key":4,
                "age":30,
                "address":"河源市白云大道"
            },
            {
                "success":200,
                "name":"嘎子哥",
                "key":4,
                "age":37,
                "address":"深圳市宝安区宝钢大道999号"
            },
            {
                "success":200,
                "name":"红豆",
                "key":6,
                "age":24,
                "address":"阳江市小岗村101号"
            },
            {
                "success":200,
                "name":"大娟",
                "key":7,
                "age":30,
                "address":"河源市白云大道"
            },
            {
                "success":200,
                "name":"嘎子哥",
                "key":8,
                "age":37,
                "address":"深圳市宝安区宝钢大道999号"
            },
            {
                "success":200,
                "name":"红豆",
                "key":9,
                "age":24,
                "address":"阳江市小岗村101号"
            },
            {
                "success":200,
                "name":"大娟",
                "key":10,
                "age":30,
                "address":"河源市白云大道"
            }
        ]
    }
}

4.在需要请求数据的文件里导入axios

import axios from 'axios'

5.请求

<script lang="ts" setup>
    import axios from 'axios';
    const dataSource: Ref<DataItem[]> = ref([]);
    // 获取表格数据
    const getTableList = () => {
       axios.get('http://127.0.0.1:5173/data/userList.json').then((res) => {
        console.log(res, 'res');
        if (res.data.data.sucess == 200) {
          dataSource.value = res.data.data.userList;
          // data = res.data.data.userList;
         } else {
          alert('数据获取失败');
        }
  });
};
</script>

6.效果图
