1. 文件--首选项--用户代码片段-vue.json : 添加

// {
// 	// Place your global snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and 
// 	// description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope 
// 	// is left empty or omitted, the snippet gets applied to all languages. The prefix is what is 
// 	// used to trigger the snippet and the body will be expanded and inserted. Possible variables are: 
// 	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. 
// 	// Placeholders with the same ids are connected.
// 	// Example:
// 	// "Print to console": {
// 	// 	"scope": "javascript,typescript",
// 	// 	"prefix": "log",
// 	// 	"body": [
// 	// 		"console.log('$1');",
// 	// 		"$2"
// 	// 	],
// 	// 	"description": "Log output to console"
// 	// }
// }
{"生成 vue 模板": {"prefix": "vue","body": ["<template>","<div></div>","</template>","","<script>","//这里可以导入其他文件（比如：组件，工具 js，第三方插件 js，json文件，图片文件等等）","//例如：import 《组件名称》 from '《组件路径》';","","export default {","//import 引入的组件需要注入到对象中才能使用","components: {},","props: {},","data() {","//这里存放数据","return {","","};","},","//计算属性 类似于 data 概念","computed: {},","//监控 data 中的数据变化","watch: {},","//方法集合","methods: {","","},","//生命周期 - 创建完成（可以访问当前 this 实例）","created() {","","},","//生命周期 - 挂载完成（可以访问 DOM 元素）","mounted() {","","},","beforeCreate() {}, //生命周期 - 创建之前","beforeMount() {}, //生命周期 - 挂载之前","beforeUpdate() {}, //生命周期 - 更新之前","updated() {}, //生命周期 - 更新之后","beforeDestroy() {}, //生命周期 - 销毁之前","destroyed() {}, //生命周期 - 销毁完成","activated() {}, //如果页面有 keep-alive 缓存功能，这个函数会触发","}","</script>","<style  scoped>","$4","</style>"],"description": "生成 vue 模板"},"http-get 请求": {"prefix": "httpget","body": ["this.\\$http({","url: this.\\$http.adornUrl(''),","method: 'get',","params: this.\\$http.adornParams({})","}).then(({data}) => {","})"],"description": "httpGET 请求"},"http-post 请求": {"prefix": "httppost","body": ["this.\\$http({","url: this.\\$http.adornUrl(''),","method: 'post',","data: this.\\$http.adornData(data, false)","}).then(({ data }) => { });"],"description": "httpPOST 请求"}
