网上有什么做兼职的网站社交网站开发用到的技术

1.下载依赖：
npm install vue-router

在src目录下新建一个文件夹router，在router文件夹下新建一个文件router.js文件,在component目录下新建增加删除和修改的组件，引入router.js当中
此时的init组件为主页面（（二、三）的app.vue），app.vue只用来写路由占位符
router.js：

import Vue from 'vue'
import Router from 'vue-router/dist/vue-router.js'
import init from '../components/init.vue'
import app from '../components/app.vue'
import add from '../components/add.vue'
import del from '../components/del.vue'
import update from '../components/update.vue'
//Vue对象挂载Router对象，所有的vue组件都能使用router当中的内容
Vue.use(Router);export default new Router({routes: [{//访问根路径的时候重定向到init路径path: '/',redirect:'/init'},{path: '/init',component: init},{path: '/add',name:'add',component: add},{path: '/del',name:'del',component: del},{path: '/update',name:'update',component: update},]
})

index.js：

import Vue from 'vue'
import App from './components/App.vue'import router from './router/router.js'const vm = new Vue({el:'#app',render:h=>h(App),router:router
})

app.vue

<template><div id="app"><router-view></router-view></div>
</template><script></script><style scoped="scoped"></style>

init.vue

<template><div class="div1"><div class="div2"><div class="div21">学号</div><div class="div21">姓名</div><div class="div21">性别</div><div class="div21">班级</div><div class="div21"></div><div class="div21"></div></div><div class="div3" v-for="item in people"><div class="div31">{{item.id}}</div><div class="div31">{{item.name}}</div><div class="div31">{{item.sex}}</div><div class="div31">{{item.class}}</div><div class="div31"><router-link to='/update'>更改</router-link></div><div class="div31"><button @click="del">删除</button></div></div><div class="div4"><router-link to='/add'>增加</router-link></div></div>
</template><script>export default {data(){return{msg:'66',people:[]}},mounted:function(){console.log('发送请求');var xhr = new XMLHttpRequest();xhr.open('POST','http://localhost:3000/init');xhr.setRequestHeader('Content-Type','application/x-www-form-urlencoded');xhr.send();var that = this;xhr.onload = function(){that.people = JSON.parse(xhr.responseText);}},methods:{}}console.log('结束')</script>
</script><style scoped="scoped">.div1{width: 800px;margin: auto;border: 1px solid transparent;}.div2{width: 100%;height: 50px;display: flex;}.div21{text-align: center;line-height: 50px;border: 1px solid aqua;flex: 1;}.div3{width: 100%;height: 50px;display: flex;}.div31{border: 1px solid aqua;text-align: center;line-height: 50px;flex: 1;}</style>

页面效果：

接下来完善一下增加、删除和更新的页面，源代码就不展示了，就是原生的HTML、css
