网站建设开票内容些什么个人怎么做免费百度推广

1.安装mockjs和axios

 cnpm install mockjs -Scnpm install axios -S

目录结构(这里的演示只用到这四个文件)

2.创建模拟返回的数据(src/mockjs/http.js),放入以下内容

//模拟的请求数据
export default {getData: () => {return {code: 200,tableData: [{id: "01",name: "get测试001",},{id: "02",name: "get测试002",},{id: "03",name: "get测试003",},{id: "04",name: "get测试004",},],};},postData: () => {return {code: 200,tableData2: [{id: "01",name: "post测试001",},{id: "02",name: "post测试002",},{id: "03",name: "post测试003",},{id: "04",name: "post测试004",},],};},
};

3.引入mock,拦截请求,返回模拟的数据(src/mockjs/index.js)放入以下内容

//引入mock进行请求/拦截请求接口
import Mock from "mockjs";
//导入模拟的数据
import httpdata from "./http.js";
//拦截请求返回模拟的数据（当访问这个接口时，返回响应的数据）
//第一个参数是请求的接口api,第二个参数是请求方式get/post,第三个参数是一个函数(数据),
Mock.mock("/home/getdata", "get", httpdata.getData);
Mock.mock("/home/postdata", "post", httpdata.postData);

4.在全局注册mock(scr/main.js)放入以下内容

import { createApp } from "vue";
import "./style.css";
import App from "./App.vue";//全局引入mock(这里只需要这一行引入)
import "./mockjs/index.js";createApp(App).mount("#app");

5.发送请求测试结果，在(src/App.vue)放入以下内容

<script setup>
//发送请求
import axios from "axios";
import { onMounted } from "vue";
onMounted(() => {//get请求axios.get("/home/getdata").then((res) => {console.log("get请求返回的数据", res);});//post请求axios.post("/home/postdata").then((res) => {console.log("post请求返回的数据", res);});
});
</script><template></template><style scoped lang="scss"></style>
