.net core vue+wangEditor (双向绑定) 上传图片和视频功能

最终效果，是这样的，现在开始记录怎么做:

开始 npm 安装 wangEditor

安装好后,

因为要用vue 双向绑定 ，所以 我就把wangwangEditor 做成了一个封装组件，先看一下目录 :

我是把wangEditor写在了my-components这个项目下，新建一个 vue组件,代码如下:

<template>
    <div id="wangeditor">
        <div ref="editorElem" style="text-align:left"></div>
    </div>
</template>
<script>
    import E from 'wangeditor'
    export default {
        name: 'editorElem',
        data() {
            return {
                editor: null,
                editorContent: ''
            }
        },
        props: ['catchData', 'content'],    // 接收父组件的方法
        watch: {
            content() {
                this.editor.txt.html(this.content)
            }
        },
        mounted() {
            var imgUrl = "";
            this.editor = new E(this.$refs.editorElem)

            this.editor.customConfig.onchange = (html) => {
                this.editorContent = html
                this.catchData(this.editorContent)  // 把这个html通过catchData的方法传入父组件
            }
            this.editor.customConfig.uploadImgServer = '/api/Media/OnPostUpload'
            this.editor.customConfig.uploadVideoServer="/api/Media/OnPostUploadVideo" // 或 /node_modules/wangeditor/release/wangEditor.js 里直接写上传视频接口
            // 下面是最重要的的方法
            this.editor.customConfig.uploadImgHooks = {
                before: function (xhr, editor, files) {
                    // 图片上传之前触发
                    // xhr 是 XMLHttpRequst 对象，editor 是编辑器对象，files 是选择的图片文件

                    // 如果返回的结果是 {prevent: true, msg: 'xxxx'} 则表示用户放弃上传
                    // return {
                    //     prevent: true,
                    //     msg: '放弃上传'
                    // }
                },
                success: function (xhr, editor, result) {
                    // 图片上传并返回结果，图片插入成功之后触发
                    // xhr 是 XMLHttpRequst 对象，editor 是编辑器对象，result 是服务器端返回的结果

                    this.imgUrl = Object.values(result.data).toString()
                },
                fail: function (xhr, editor, result) {
                    debugger;
                    var res = xhr.data;
                    // 图片上传并返回结果，但图片插入错误时触发
                    // xhr 是 XMLHttpRequst 对象，editor 是编辑器对象，result 是服务器端返回的结果
                },
                error: function (xhr, editor) {
                    debugger;
                    // 图片上传出错时触发
                    // xhr 是 XMLHttpRequst 对象，editor 是编辑器对象
                },
                timeout: function (xhr, editor) {
                    // 图片上传超时时触发
                    // xhr 是 XMLHttpRequst 对象，editor 是编辑器对象
                },

                // 如果服务器端返回的不是 {errno:0, data: [...]} 这种格式，可使用该配置
                // （但是，服务器端返回的必须是一个 JSON 格式字符串！！！否则会报错）
                customInsert: function (insertImg, result, editor) {
                    // 图片上传并返回结果，自定义插入图片的事件（而不是编辑器自动插入图片！！！）
                    // insertImg 是插入图片的函数，editor 是编辑器对象，result 是服务器端返回的结果

                    // 举例：假如上传图片成功后，服务器端返回的是 {url:'....'} 这种格式，即可这样插入图片：
                    let url = Object.values(result.data)      // result.data就是服务器返回的图片名字和链接
                    JSON.stringify(url)    // 在这里转成JSON格式
                    insertImg(url)
                    // result 必须是一个 JSON 格式字符串！！！否则报错
                },
            };
            this.editor.customConfig.debug = true;
            this.editor.create()     // 创建富文本实例
            if (!this.content) {
                this.editor.txt.html('请编辑内容1')
            }
        }
    }
</script>

　　然后，再在主页面上，引用 ，和感觉和后端差不多

<template>
<editorElem :catchData="catchData" :content="channelForm.content"></editorElem> (:content 这里就是双向绑定)
</template>

import editorElem from "../../my-components/Editor.vue";

export default {

name: "editor",
   components: {
       editorElem
   }

}

接着，开始改wangEidotr的视频上传代码，原wangEidotr上传视频用的不怎么好，所以我就去网上找了大神的( https://blog.csdn.net/m0_37885651/article/details/83660206 )代码修改了一下,

先找到wangEidotr.js 

//

    this.$elem = $('<div class="w-e-menu"><i class="w-e-icon-play"><i/></div>');

// 修改原型
Editor.prototype = {
    constructor: Editor,

    // 添加视频上传
    _initUploadVideo: function _initUploadVideo() {
        this.uploadVideo = new UploadVideo(this);
    },
    // 创建编辑器
    create: function create() {

        // 添加 视频上传
        this._initUploadVideo();
    },

};

1，源码里找到Video 的构造函数 还有它的prototype，替换成第一部分。(有版本是一样的，可以不替换)
2，找到UploadImg的构造函数，还有它的prototype，这是上传图片的，相应的 你在这后面 加上第二部分UploadVideo的构造和原型，这是专门写的上传视频的。
3，在Editor原型上加个方法，_initUploadVideo , 然后在 创建编辑器 create 里面执行 this._initUploadVideo() ，加上就可以。

下面是后端代码:
