背景
本文为大家分享了asp.net core 如何集成CKEditor ,并实现图片上传功能的具体方法,供大家参考,具体内容如下。

准备工作
1.visual studio 2019 开发环境
2.net core 2.0 及以上版本

实现方法
1、新建asp.net core web项目

2、下载CKEditor
这里我们新建了一个系统自带的样本项目,去 CKEditor官网下载一个版本,解压后拷贝大wwwroot中

3、增加图片上传控制器
@using CompanyName.ProjectName.Web.Host.Web.Model
@model demock
@{
    ViewData["title"] = "堆代码 duidaima.com";
    Layout = "_SimpleTable";
}
@section headers{
    @*<style>
            .nav.nav-tabs.padding-18 {
                padding-left: 18px;
            }
            .nav-tabs {
                border-color: #c5d0dc;
                margin-bottom: 0 !important;
                margin-left: 0;
                position: relative;
                top: 1px;
            }
</style>*@
}

<section class="content">
    <div class="box box-primary">
        <div class="box-header with-border">
            <ul class="nav nav-tabs padding-18">
                <li>

                    <a href="/demo/sendmail">
                        <i class="orange ace-icon fa fa-cog bigger-120"></i>
                        发邮件
                    </a>
                </li>
                <li class="active">
                    <a href="javascript:void(0);">

                        <i class="green ace-icon fa fa-home bigger-120"></i>

            var files = Request.Form.Files;

            string url = "http://" + Request.Host.Value;
            output = string.Format(output, Request.Query["CKEditorFuncNum"], url + "/" + fileName2);
            ViewBag.cc = output;
            return View();
        }
4、增加图片上传控制器注意返回是一个json对象,因此建了一个简单的对象返回。

运行效果
