1.在vue.config.js 文件中添加 一下内容

const webpack = require('webpack');

new webpack.ProvidePlugin({
        'window.Quill': 'quill/dist/quill.js',
        'Quill': 'quill/dist/quill.js'
      }),

2.下载安装插件

// 拖拽上传
npm install quill-image-drop-module --save
// 调整上传图片大小
npm i quill-image-resize-module --save 
// 粘贴图片上传
npm install quill-image-extend-module --save

3.在Editor组件中引入插件

修改ruoyi-ui\src\components\Editor下的 index.vue 文件

<template>
  <div>
    <el-upload
      :action="uploadUrl"
      :before-upload="handleBeforeUpload"
      :on-success="handleUploadSuccess"
      :on-error="handleUploadError"
      name="file"
      :show-file-list="false"
      :headers="headers"
      style="display: none"
      ref="upload"
      v-if="this.type == 'url'"
    >
    </el-upload>
    <div class="editor" ref="editor" :style="styles"></div>
  </div>
</template>

<script>
import Quill from "quill";

import "quill/dist/quill.bubble.css";
import { getToken } from "@/utils/auth";

// 拖拽上传
import {ImageDrop} from 'quill-image-drop-module';
// 调整上传图片大小
import ImageResize from 'quill-image-resize-module';
// 粘贴图片上传
import {ImageExtend} from 'quill-image-extend-module';
// 注册事件~~~~
Quill.register('modules/imageDrop', ImageDrop);
Quill.register('modules/imageResize', ImageResize);
Quill.register('modules/imageExtend', ImageExtend);

4.使用Editor组件（特别注意要的加 v-if ）

<template>
  <div class="app-container">
    <!-- 此处一定要加上这个v-if判断，目的：保证那边只执行一次
        不然 editor 那边会触发两次(初始化rtfContent一次，rtfContent值改变一次),
        导致出现quil会出现一些问题。  -->
      <div label="内容" v-if="form.rtfContent!=undefined">
          <editor v-model="form.rtfContent" :min-height="192"/>
      </div>
  </div>
</template>

<script>
import {addProfile, delProfile, getProfile, listProfile, updateProfile} from "@/api/yangdong/centerprofile";

export default {
  name: "Profile",
  data() {
    return {
      rtfContent: undefined,
      },
    };
  },
  created() {
    this.getList();
  },
  mounted() {
    
  },
  methods: {
    /** 查询中心简介列表 */
    getList() {
      this.loading = true;
      listProfile(this.queryParams).then(response => {
        this.rtfContent= response.rows.rtfContent;
      });
    },
   }
};
</script>

<style scoped>
.testParent{
  /*width: 700px;*/
  /*height: 200px;*/
  display: flex;
  flex-direction: row; /*默认也是row可以不写*/
  /*background-color: #428BCA;*/
  align-items: center;  /*这种情况是垂直居中*/
  justify-content: center;/*这种情况是水平居中*/

}

/deep/ .el-table th.must>.cell:before {
  content: '*';
  color: #ff1818;
}

/* 以下为详情遮住样式*/
::v-deep .avue-crud__dialog__header {
  display: -webkit-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  -webkit-box-pack: justify;
  -ms-flex-pack: justify;
  justify-content: space-between;
}
/* 以下为缩放按钮样式*/

  cursor: pointer;
}
::v-deep .el-icon-full-screen:before {
  content: "\e719";
}
</style>

5.bug 之 imageResize的 img的style丢失

原因：

执行this.Quill.pasteHTML(this.currentValue) 的时候，
会把htm的代码渲染在富文本(Quill) ，但是却把在img上面的style被清除掉了,于是就出现了再次编辑时图片位置异常

解决方式：

直接也研究了半天，最后虽然实现了，但是过程很复杂，采取了DOM 操作（加点击事件，重新渲染html、重新渲染quil等等），过程极其难受
本人不是纯弄前端，心累的很。。。。。
后面发现了一篇博客，方式简单（使用了 自定义的Quill.js的Blot（块）），果断用了他的。在此非常感谢
博客地址如下：vue使用quill编辑器自定义图片上传方法、quill-image-resize-module修改图片、监测粘贴的是图片上传到后端、重新进入编辑器img标签丢失style属性

1.先创建一个image.js的文件

由于我这边是若依框架里面的。所以的位置为 ruoyi-ui\src\components\Editor,和index.vue 并级

import Quill from 'quill'
const EmbedBlot = Quill.import('formats/image')
// 添加style,解决重进编辑器ima标签丢掉style属性问题
const ATTRIBUTES = ['alt', 'height', 'width', 'style']

class Image extends EmbedBlot {
  static blotName = 'image';
  static tagName = 'IMG';

  static create(value) {
    const node = super.create(value)
    if (typeof value === 'string') {
      // 保留原来的图片方法
      node.setAttribute('src', this.sanitize(value))
    } else {
      // 自定义图片方法
      node.setAttribute('src', value.src)
      // 使用了vue-photo-preview所以添加preview，preview-text这两个属性
      node.setAttribute('preview', '1') // preview相同的为一组
      node.setAttribute('preview-text', value.title) // 图片名称，预览时显示使用
    }
    return node
  }

  static formats(domNode) {
    return ATTRIBUTES.reduce((formats, attribute) => {
      if (domNode.hasAttribute(attribute)) {
        formats[attribute] = domNode.getAttribute(attribute)
      }
      return formats
    }, {})
  }

  static match(url) {
    return /\.(jpe?g|gif|png)$/.test(url) || /^data:image\/.+;base64/.test(url)
  }

  static register() {
    if (/Firefox/i.test(navigator.userAgent)) {
      setTimeout(() => {
        // Disable image resizing in Firefox
        // @ts-expect-error
        document.execCommand('enableObjectResizing', false, false)
      }, 1)
    }
  }

  static sanitize(url) {
    return sanitize(url, ['http', 'https', 'data']) ? url : '//:0'
  }

  static value(domNode) {
    return domNode.getAttribute('src')
  }

  format(name, value) {
    if (ATTRIBUTES.indexOf(name) > -1) {
      if (value) {
        this.domNode.setAttribute(name, value)
      } else {
        this.domNode.removeAttribute(name)
      }
    } else {
      super.format(name, value)
    }
  }
}
function sanitize(url, protocols) {
  const anchor = document.createElement('a')
  anchor.href = url
  const protocol = anchor.href.slice(0, anchor.href.indexOf(':'))
  return protocols.indexOf(protocol) > -1
}

export default Image

2.引入并注册 image.js 到Editor的vue文件中

import Image from "./image";
Quill.register(Image, true);

完整的代码如下

<template>
  <div>
    <el-upload
      :action="uploadUrl"
      :before-upload="handleBeforeUpload"
      :on-success="handleUploadSuccess"
      :on-error="handleUploadError"
      name="file"
      :show-file-list="false"
      :headers="headers"
      style="display: none"
      ref="upload"
      v-if="this.type == 'url'"
    >
    </el-upload>
    <div class="editor" ref="editor" :style="styles"></div>
  </div>
</template>

<script>

import {ImageDrop} from 'quill-image-drop-module';
// 调整上传图片大小
import ImageResize from 'quill-image-resize-module';

// 注册事件~~~~
Quill.register('modules/imageDrop', ImageDrop);
Quill.register('modules/imageResize', ImageResize);
Quill.register('modules/imageExtend', ImageExtend);

import Image from "./image";
Quill.register(Image, true);

6.配置监听黏贴事件（看个人需求）

参考：若依框架前后分离版本富文本增加图片上传及移动和放大缩小

（1）首先得安装jq

npm install jquery --save-dev

（2）引入jq

//引入jq
import $ from 'jquery';

（3）修改以下代码

• 原来

<div class="editor" ref="editor" :style="styles"></div>

• 改为

<div class="editor" ref="editor" :style="styles" @paste="handlePaste($event)"></div>

增加

handlePaste(evt) {
      let that = this
      if (evt.clipboardData &&
        evt.clipboardData.files &&
        evt.clipboardData.files.length) {
        evt.preventDefault();
        [].forEach.call(evt.clipboardData.files, (file) => {
          if (!file.type.match(/^image\/(gif|jpe?g|a?png|bmp)/i)) {
            return;
          }
          const formData = new FormData();
          formData.append("file", file);//后台上传接口的参数名
          // 实现上传
          $.ajax({
            type: "post",
            url: process.env.VUE_APP_BASE_API +'/common/upload', // 上传的图片服务器地址
            data: formData,
            headers:{'Authorization': "Bearer " + getToken()},//必须
            dataType: "json",
            processData: false,
            contentType: false,//设置文件上传的type值，必须
            success: (response) => {
              if (response.code == 200 || response.code == 0) {
                //当编辑器中没有输入文本时，这里获取到的 range 为 null
                // 获取富文本组件实例
                let quill = that.Quill;
                var range = quill.selection.savedRange;
                //图片插入在富文本中的位置
                var index = 0;
                if (range == null) {
                  index = 0;
                } else {
                  index = range.index;
                }
                //将图片链接插入到当前的富文本当中
                quill.insertEmbed(index, "image", response.url);
                // 调整光标到最后
                quill.setSelection(index + 1); //光标后移一位
              }
            },
            error: function () {
              this.$message.error('上传失败！')
            },
          });
        });
      }
    },

完整的代码如下

<template>
  <div>
    <el-upload
      :action="uploadUrl"
      :before-upload="handleBeforeUpload"
      :on-success="handleUploadSuccess"

      ref="upload"
      v-if="this.type == 'url'"
    >
