httpget和post模板

一直用的hbuilder，到这里发现怎么设置也不生效，于是转vscode了

new global snippets file，手工创建模板vue.config-snippets

 

 模板内容

    "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"
    },

本节主要用到了

MessageBox 弹框

this.$confirm(`确认提示`, "提示", {
        confirmButtonText: "确定",
        cancelButtonText: "取消",
        type: "warning",
      })
     .then(() => {})
     .catch(() => {});

Message 消息提示

            this.$message({
              message: "提示消息",
              type: "success",
            });

default-expanded-keys

指定展开节点的key，及node-key

 我的category.vue源码

<template>
  <div>
    <el-tree
      :data="menus"
      :props="defaultProps"
      show-checkbox=""

      :expand-on-click-node="false"
      :default-expanded-keys="expandedkey"

      <span class="custom-tree-node" slot-scope="{ node, data }">

            @click="() => append(data)"
          >
