React使用富文本CKEditor 5，上传图片并可设置大小

上传图片

基础使用（标题、粗体、斜体、超链接、缩进段落、有序无序、上传图片）
官网查看：https://ckeditor.com/docs/ckeditor5/latest/installation/integrations/react.html

安装依赖

npm install --save @ckeditor/ckeditor5-react @ckeditor/ckeditor5-build-classic

使用

import { CKEditor } from '@ckeditor/ckeditor5-react';
import ClassicEditor from '@ckeditor/ckeditor5-build-classic';




<CKEditor
   editor={ ClassicEditor }
   data="<p>Hello from CKEditor&nbsp;5!</p>"
   onReady={ editor => {
       // You can store the "editor" and use when it is needed.
       console.log( 'Editor is ready to use!', editor );
   } }
   onChange={ ( event, editor ) => {
       const data = editor.getData();
       console.log( { event, editor, data } );
   } }
   onBlur={ ( event, editor ) => {
       console.log( 'Blur.', editor );
   } }
   onFocus={ ( event, editor ) => {
       console.log( 'Focus.', editor );
   } }
    extraPlugins={[(editor) => {
          	editor.plugins.get( 'FileRepository' ).createUploadAdapter = ( loader ) => {
    return new MyUploadAdapter( loader );
};

/>

在这里插入图片描述

import { PageContainer } from '@ant-design/pro-components';
import { Access, useAccess } from '@umijs/max';
import { Button } from 'antd';
import { CKEditor } from '@ckeditor/ckeditor5-react'
import ClassicEditor from '@/components/Editor/ckeditor';
const AccessPage: React.FC = () => {
  const access = useAccess();
  return (
    <PageContainer
      ghost
      header={{
        title: '权限示例',
      }}
    >
      <Access accessible={access.canSeeAdmin}>
        <Button>只有 Admin 可以看到这个按钮</Button>


      </Access>

      <div style={{ marginTop: 40}}>
        <CKEditor
          editor={ClassicEditor}
          config={{
            toolbar: {
              items: [
                'heading',
                '|',
                'bold',
                'italic',
                'link', //链接
                'bulletedList', //无序排序
                'numberedList', //有序排序

                'outdent',
                'indent',

              ]
            },
            image: {

          }}
          extraPlugins={[(editor) => {
          	editor.plugins.get( 'FileRepository' ).createUploadAdapter = ( loader ) => {
    return new MyUploadAdapter( loader );

图片上传adapter

上传图片逻辑

MyUploadAdapter.js

class MyUploadAdapter {
    constructor( loader ) {
        // The file loader instance to use during the upload.
        this.loader = loader;
    }

    // Starts the upload process.
    upload() {
        // Return a promise that will be resolved when the file is uploaded.
        return loader.file
            .then( file => {
				//上传图片逻辑,必须是异步的，否则在富文本框无法正常渲染图片
					return {
					
						default: ''//图片链接
					}

			} );
    }

    // Aborts the upload process.
    abort() {
    }
}

{
    default: 'http://example.com/images/image–default-size.png'
}
