若依框架图片上传、富文本框编辑器功能

一、前言

现在的需求是：实现一个项目展示模块，后端管理页面除了需要基础信息外，要加上一个图片上传和富文本框编辑器功能。

二、效果

点击”图片存储地址”：可上传电脑任何位置的图片，并可对图片进行放大，缩小，和旋转。

存入数据库的图片以url地址存放

url直接百度可看到图片：

三、编码过程

1.前端：

index.vue

<template>
  <div class="app-container">
    
    <el-row :gutter="10" class="mb8">
      <el-col :span="1.5">
        <el-button
          type="primary"
          plain
          icon="el-icon-plus"
          size="mini"
          @click="handleAdd"
          >新增
        el-button>
      el-col>
    el-row>
