vue+ckEditor5 复制粘贴wold文字+图片并保存格式

第一步在vue2项目下安装

复制代码

npm install --save @ckeditor/ckeditor5-build-decoupled-document

第二项目下新建一个plugins的文件夹将这个包ckeditor5-build-classic放入

（包在页面最上方有个下载按钮可以下载）

刚开始时 ckeditor5-build-classic文件夹下无node_modules,需要找到项目下的ruoyi-ui\src\plugins\ckeditor5-build-classic文件地址，cmd打开，然后输入npm install 安装下 ckeditor5-build-classic文件夹下就有这个了node_modules

第三步（为了兼容wold和pdf的粘贴）

找到plugins\ckeditor5-build-classic\node_modules@ckeditor\ckeditor5-paste-from-office\src\filters\image.js 这个文件，然后打开，搜索regexPictureHeader，将某段代码进行替换如下

复制代码

//图片替换
regexPictureHeader = /{\pict[\s\S]+?({\*\blipuid\s?[\da-fA-F]+})+?/;

第四步（为了兼容wold和pdf的粘贴）

找到plugins\ckeditor5-build-classic\node_modules@ckeditor\ckeditor5-paste-from-office\src\filters\space.js 这个文件，然后打开，搜索htmlDocument.querySelectorAll，将这段代码替换如下

复制代码

htmlDocument.querySelectorAll('span[style*=spacerun]').forEach(el => {
 if (/[^\b]/.test(el.innerText.trim()) === false) {
 const innerTextLength = el.innerText.length || 0;
 el.innerHTML = Array(innerTextLength + 1).join('\u00A0 ').substr(0, innerTextLength);
 }
 });

第五步在api文件下新建upload.js

复制代码

import { getToken } from "@/utils/auth";
// upload.js中
class MyUploadAdapter {
  constructor(loader) {
    // 要在上载期间使用的文件加载器实例
    this.loader = loader;
  }

  // 启动上载过程
  upload() {
    return this.loader.file.then(
      (file) =>
        new Promise((resolve, reject) => {
          this._initRequest();
          this._initListeners(resolve, reject, file);
          this._sendRequest(file);
        })
    );
  }

  // 中止上载过程
  abort() {
    if (this.xhr) {
      this.xhr.abort();
    }
  }

  // 使用传递给构造函数的URL初始化XMLHttpRequest对象.
  _initRequest() {
    const xhr = (this.xhr = new XMLHttpRequest());
    // 后端上传图片接口     `${process.env.VUE_APP_BASE_API}/common/upload`,
    xhr.open(
      "POST",
      `${process.env.VUE_APP_BASE_API}/common/upload`,
      true
    );
    xhr.responseType = "json";
  }

  // 初始化 XMLHttpRequest 监听.
  _initListeners(resolve, reject, file) {
    const xhr = this.xhr;
    const loader = this.loader;
    const genericErrorText = `无法上传文件: ${file.name}.`;

    xhr.addEventListener("error", () => reject(genericErrorText));
    xhr.addEventListener("abort", () => reject());
    xhr.addEventListener("load", () => {
      //这个例子假设XHR服务器的"response"对象将附带
      //一个"error"，它有自己的"message"，可以传递给reject()
      //你的集成可能以不同的方式处理上传错误，所以请确保
      //当上传失败时，必须调用reject()函数。
      const response = xhr.response;
      // 当上传失败时，必须调用reject()函数。
      if (!response || response.error) {
        // reject方法会调用浏览器的alert事件 并清除页面上的图片展示
        return reject(
          response && response.error
            ? response.error.message
            : genericErrorText
        );
      }
      // 上传成功，从后台获取图片的url地址
      // resolve方法会将default中的值插入到页面中img标签的src中
      resolve({
        default: response.url,
      });
    });

    // 支持时上传进度。文件加载器有#uploadTotal和#upload属性，用于在编辑器用户界面中显示上载进度栏。
    if (xhr.upload) {
      xhr.upload.addEventListener("progress", (evt) => {
        if (evt.lengthComputable) {
          loader.uploadTotal = evt.total;
          loader.uploaded = evt.loaded;
        }
      });
    }
  }

  // 准备数据并发送请求
  _sendRequest(file) {
    // 通过FormData构造函数创建一个空对象
    const data = new FormData();
    // 通过append()方法在末尾追加key为files值为file的数据
    data.append("file", file); // 上传的参数data
    /**
     * 重要提示:这是实现诸如身份验证和CSRF保护等安全机制的正确位置。
     * 例如，可以使用XMLHttpRequest.setRequestHeader()设置包含应用程序先前生成的CSRF令牌的请求头。
     */
    this.xhr.setRequestHeader("Authorization", getToken());
    this.xhr.send(data);
  }
}

function MyCustomUploadAdapterPlugin(editor) {
  editor.plugins.get('FileRepository').createUploadAdapter = (loader) => {
    // 在这里将URL配置为后端上载脚本
    return new MyUploadAdapter(loader)
  }
}

export {
  MyUploadAdapter,
  MyCustomUploadAdapterPlugin
}
