tinymce 5.0 粘贴word带图片

业务需求

在现有tinymce编辑器的基础上增加复制ctrl+c复制图片和ctrl+v粘贴图片并上传到服务器的功能，需要支持信创国产化环境，因为是给一个国企单位做的项目，现在有这个要求。

技术栈

vue2+js+tinymce 5.0

业务实现

之前的逻辑是将tinymce放到public下面。

//初始化增加配置{paste_data_images:true,//允许粘贴图片images_upload_handler:(blobInfo,success,failure,progress)=>{//blobInfo:粘贴的图片的blob//succuss：上传完成调用//failure：上传失败调用this.handleImgUpload(blobInfo,success,failure,progress)}}

发现问题

从微信、本地、word纯图片复制都可以回显，但是word复制图文混合就不行。

问题原因

原因是word图文混合里面的img标签src都是以file://开头的本地地址

解决问题

tinymce有付费软件powerpaste
自己写 参考了以下两个tinymce6的帖子：

用的是tinymce5 所以参考第二篇文章的回答，改造一下现有的paste插件（只是改造了一下，还是要用安装原来的插件的！！）
改造思路：
1.官方自带的 paste 已经自带过滤器，但是过滤了img->修改自带的过滤器（尝试过完全放弃自带的过滤，取消paste_enabled_default_filter 但是word中的无效元素太多了,自建过滤器在在网上抄了很多还不如原来的)
2. paste_preprocess - 粘贴内容插入编辑器之前的钩子。在这里提取图片，并将图片上传到服务器，再将粘贴内容插入到编辑器中。

处理粘贴插件

tinymce5 粘贴插件用的是ts，从网上下了一份js的。也能将就着用，尝试用第一个文章中的过滤器但是不知道为什么过滤之后还是有很多无效元素，看了paste源码发现自带的过滤器实现已经很好了所以在原来的过滤上做改造。
本步骤主要做了两件事：

删除自带过滤器中对图片的过滤
过滤rtf中word适配低版本ie的vml标签，以免在后面从rtf中正则切割有问题
