Asp.Net Core中配置使用Kindeditor富文本编辑器实现图片上传和截图上传及文件管理和上传（开源代码.net core3.0）

kindeditor使用javascript编写，可以无缝的于java、.net、php、asp等程序接合。 kindeditor非常适合在cms、商城、论坛、博客、wiki、电子邮件等互联网应用上使用，2006年7月首次发布2.0以来，kindeditor依靠出色的用户体验和领先的技术不断扩大编辑器市场占有率，目前在国内已经成为最受欢迎的编辑器之一。

然而很多人缺为在asp.net core中的使用在发愁，于是这个开源demo就这样产生了，那么我现在给各位介绍下它的快速使用吧！

一、前端配置

1.首先引用相关文件

<link rel="stylesheet" href="~/lib/kindeditor/themes/default/default.css" />
<link rel="stylesheet" href="~/lib/kindeditor/plugins/code/prettify.css" />
<script charset="utf-8" src="~/lib/kindeditor/kindeditor-all.js"></script>
<script charset="utf-8" src="~/lib/kindeditor/lang/zh-cn.js"></script>
<script charset="utf-8" src="~/lib/kindeditor/plugins/code/prettify.js"></script>

2.建立编辑器标签（已有的数据直接渲染在标签内即可加载至编辑器）

<textarea name="content" style="width:100%;height:450px;" id="myeidtor">@html.raw(model.context)</textarea>

3.初始化编辑器，并配置图片及文件管理、上传

kindeditor.ready(function (k) {
        window.editor = k.create('#myeidtor', {
            uploadjson: '../../editor/kindsavefiles?title=@html.raw(model.title)&contextid=@model.id',
            filemanagerjson: '@url.action("kindfilemanager", "editor")',
            allowfilemanager: true,
            autoheightmode : true,
                    aftercreate: function () {
                        var editerdoc = this.edit.doc;//得到编辑器的文档对象
                        //监听粘贴事件, 包括右键粘贴和ctrl+v
                        $(editerdoc).bind('paste', null, function (e) {
                            var ele = e.originalevent.clipboarddata.items;
                            for (var i = 0; i < ele.length; ++i) {
                                //判断文件类型
                                if (ele[i].kind == 'file' && ele[i].type.indexof('image/') !== -1) {
                                    var file = ele[i].getasfile();//得到二进制数据
                                    //创建表单对象，建立name=value的表单数据。
                                    var formdata = new formdata();
                                    formdata.append("imgfile", file);//name,value

                                    //用jquery ajax 上传二进制数据
                                    $.ajax({
                                        url: '../../editor/kindsavefiles?dir=image&title=@html.raw(model.title)&contextid=@model.id',
                                        type: 'post',
                                        data: formdata,
                                        // 告诉jquery不要去处理发送的数据
                                        processdata: false,
                                        // 告诉jquery不要去设置content-type请求头
                                        contenttype: false,
                                        datatype: "json",
                                        beforesend: function () {
                                            //console.log("正在进行，请稍候");
                                        },
                                        success: function (responsestr) {
                                            //上传完之后，生成图片标签回显图片，假定服务器返回url。
                                            var src = responsestr.url;
                                            var imgtag = "<img src='" + src + "' border='0'/>";

                                            //console.info(imgtag);
                                            //kindeditor提供了一个在焦点位置插入html的函数，调用此函数即可。
                                            editor.inserthtml(imgtag);


                                        },
                                        error: function (responsestr) {
                                            console.log("error");
                                        }
                                    });

                                }

                            }
                        }
                        )
                    }

        });
     });

4.获取数据保存

 

function btnsave() {
        alert(window.editor.html());//获取了数据，保存就没问题了吧！
    }

 

二、后台配置接收文件处理并返回预定格式的json数据

#region kindeditor
        private string kindstr = "kind";//前缀文件名，可自行修改
        public iactionresult kindeditor()
        {
            article article = new article();
            article.context = "这是编辑器测试数据！";
            article.id = 1;
            article.title = "测试";
            return view(article);
        }

        public async task<iactionresult> kindsavefiles(string dir, string title, long contextid = 0, long articletypeid = 0)
        {
            if (request.form.files.count() == 0)
            {
                return showerror("请选择上传的文件");
            }

            var file = request.form.files[0];//kindeditor的上传文件控件，一次只传一个文件

            //定义允许上传的文件扩展名
            hashtable exttable = new hashtable();
            exttable.add("image", "gif,jpg,jpeg,png,bmp");
            exttable.add("flash", "swf,flv");
            exttable.add("media", "swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb,mp4");
            exttable.add("file", "doc,docx,xls,xlsx,ppt,htm,html,txt,zip,rar,gz,bz2");

            if (string.isnullorempty(dir))
            {
                dir = "image";
            }
            string fname = "";
            string filename = "";
            string md5 = commonhelper.calcmd5(file.openreadstream());
            string fileext = path.getextension(file.filename).tolower();

            if (string.isnullorempty(fileext) || array.indexof(((string)exttable[dir]).split(','), fileext.substring(1).tolower()) == -1)
            {
                return showerror("上传文件扩展名是不允许的扩展名。\n只允许" + ((string)exttable[dir]) + "格式。");
            }

            //创建文件夹
            string dirpath = confighelper.getsectionvalue("filemap:filepath") + "\\"+ kindstr + "\\" + dir + "\\";
            string webpath = "/" + kindstr + "/" + dir + "/";
            if (!directory.exists(dirpath))

            using (filestream fs = system.io.file.create(filename))
            {
                await file.copytoasync(fs);
                fs.flush();
            }
            fname = confighelper.getsectionvalue("filemap:fileweb") + webpath + newfilename;

            hashtable hash = new hashtable();
            hash["error"] = 0;
