在netcore的web项目中使用kindeditor

本项目是一个.net core的mvc项目

1.下载kindeditor 4.1.11 解压后将文件夹置于 wwwroot目录下，如图:

2.在HomeController的Index控制器对应的index视图输入一下代码:

@{
    Layout = null;
}
<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <title>我是管理员首页</title>
    @*首先要引入关键的两个js*@
    <script charset="utf-8" src="/kindeditor/kindeditor-all-min.js"></script>
    <script charset="utf-8" src="/kindeditor/lang/zh-CN.js"></script>
    @*创建KindEditor对象*@
    <script>
        KindEditor.ready(function (K) {
            K.create('#editor_id', {
                //注意kindeditor包里面自带的是一个ashx的一班处理程序 此处改为mvc的控制器方法
                uploadJson: '@Url.Action("KindeditorPicUpload", "KEUpload")',
                //fileManagerJson: '/kindeditor/asp.net/file_manager_json.ashx',
                allowFileManager: true
            });

        });
    </script>
</head>
<body>
    <div>管理从此开始</div>
    <form action="/home/index" method="post">
        <div>
            <textarea id="editor_id" name="content" style="width:700px;height:300px;">
            <strong>HTML内容</strong>
            </textarea>
        </div>
        <div><input type="submit" value="提交" /></div>
    </form>
</body>
</html>

3.在以上代码中使用到了KindeditorPicUpload控制的KEUpload用于处理文本编辑器里面的图片上传

下面是这个控制器代码:

using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using System.Collections.Generic;
using System.IO;
using System.Net.Http.Headers;

namespace Kdeditor.Start.Controllers
{
    public class KEUploadController : Controller
    {
        private IHostingEnvironment hostingEnv;
        public IActionResult Index()
        {
            return View();
        }
        public KEUploadController(IHostingEnvironment env)
        {
            this.hostingEnv = env;
        }
        /// <summary>
        /// Kindeditor图片上传
        /// </summary>
        /// <param name="imgFile">Kindeditor图片上传自带的命名，不可更改名称</param>
        /// <param name="dir">不可更改名称 这里没有用到dir</param>
        /// <returns></returns>
        public IActionResult KindeditorPicUpload(IList<IFormFile> imgFile, string dir)
        {
            //http://www.cnblogs.com/fireicesion/p/9490901.html
            //https://www.cnblogs.com/fishpro/p/how_upload_pic_with_kindeditor_for_asp_net_core.html
            //注意 如果是上传到本地这个文件夹子  那么事先必须创建这个文件夹
            PicUploadResponse rspJson = new PicUploadResponse() { error = 0, url = "/upload/" };
            long size = 0;
            string tempname = "";
            foreach (var file in imgFile)
            {
                var filename = ContentDispositionHeaderValue
                                .Parse(file.ContentDisposition)
                                .FileName
                                .Trim('"');
                //获取每个图片的扩展名
                var extname = filename.Substring(filename.LastIndexOf("."), filename.Length - filename.LastIndexOf("."));
                //创建新的文件名 guid+扩展名
                var filename1 = System.Guid.NewGuid().ToString() + extname;
                tempname = filename1;
                var path = hostingEnv.WebRootPath;
                filename = hostingEnv.WebRootPath + $@"\upload\{filename1}";
                size += file.Length;
                using (FileStream fs = System.IO.File.Create(filename))
                {
                    file.CopyTo(fs);
                    fs.Flush();
                    //这里是业务逻辑
                }
            }
            rspJson.error = 0;
            rspJson.url = $@"../../upload/" + tempname;
            return Json(rspJson);
        }
     
    }
    public class PicUploadResponse
    {
        public int error { get; set; }
        public string url { get; set; }
    }

}
