本文实例为大家分享了CKEditor与dotnetcore实现图片上传的具体代码，供大家参考，具体内容如下

CKEditor的使用

1.引入js库

<script src="https://cdn.ckeditor.com/4.6.1/standard-all/ckeditor.js"></script>

2.定义一个textarea标签

<textarea id="editor"> </textarea>

3.用CkEditor替换textarea即可使用基本功能

CKEDITOR.replace('editor');

4.配置CkEditor

添加图片上传，代码插入工具

CKEDITOR.replace('editor-box', { //GitHub地址：https://github.com/ckeditor toolbar: [ { name: 'document', items: ['Source'] }, { name: 'basicstyles', items: ['Bold', 'Italic'] }, { name: 'paragraph', items: ['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', '-', 'Blockquote'] }, { name: 'links', items: ['Link', 'Unlink'] }, { name: 'insert', items: ['Image','CodeSnippet'] }, { name: 'styles', items: ['Format', 'Styles'] } ], filebrowserImageUploadUrl: '/Blogs/UploadImageUrl', //配置图片上传后台Url customConfig: '', extraPlugins: 'codesnippet,image2,uploadimage', removePlugins: 'image', //mathJaxLib: 'https://cdn.mathjax.org/mathjax/2.6-latest/MathJax.js?config=TeX-AMS_HTML', codeSnippet_theme: 'ir_black', height: 450, contentsCss: ['https://cdn.ckeditor.com/4.6.1/standard-all/contents.css'], format_tags: 'p;h1;h2;h3;pre', removeDialogTabs: 'image:advanced;link:advanced;link:target', stylesSet: [ { name: 'Marker', element: 'span', attributes: { 'class': 'marker' } }, { name: 'Cited Work', element: 'cite' }, { name: 'Inline Quotation', element: 'q' }, { name: 'Special Container', element: 'div', styles: { padding: '5px 10px', background: '#eee', border: '1px solid #ccc' } }, { name: 'Compact table', element: 'table', attributes: { cellpadding: '5', cellspacing: '0', border: '1', bordercolor: '#ccc' }, styles: { 'border-collapse': 'collapse' } }, { name: 'Borderless Table', element: 'table', styles: { 'border-style': 'hidden', 'background-color': '#E6E6FA' } }, { name: 'Square Bulleted List', element: 'ul', styles: { 'list-style-type': 'square' } }, { name: 'Illustration', type: 'widget', widget: 'image', attributes: { 'class': 'image-illustration' } }, { name: 'Featured snippet', type: 'widget', widget: 'codeSnippet', attributes: { 'class': 'code-featured' } }, { name: 'Featured formula', type: 'widget', widget: 'mathjax', attributes: { 'class': 'math-featured' } } ] });

5.后台接收图片

/// <summary> /// 图片上传 /// </summary> /// <param name="env"></param> /// <returns></returns> public async Task<IActionResult> UploadImageUrl([FromServices]IHostingEnvironment env) { // CKEditor提交的很重要的一个参数 string callback = Request.Query["CKEditorFuncNum"]; var form = Request.Form; var img = form.Files[0]; //获取图片 string fileName = img.FileName; var openReadStream = img.OpenReadStream(); byte[] buff = new byte[openReadStream.Length]; await openReadStream.ReadAsync(buff, 0, buff.Length); string filenameGuid = Guid.NewGuid().ToString(); var bowerPath = PathUtils.GetSavePath(filenameGuid, true) + ".jpg";//获取到图片保存的路径，这边根据自己的实现 var savePath = Path.Combine(env.WebRootPath, bowerPath); using (FileStream fs = new FileStream(savePath, FileMode.Create)) { await fs.WriteAsync(buff, 0, buff.Length); //服务器返回JavaScript脚本 string result = $"<script type=\"text/javascript\">window.parent.CKEDITOR.tools.callFunction(\"{callback}\", \"{"/"+bowerPath}\", \"\");</script>"; Response.ContentType = "text/html;charset=UTF-8"; return Content(result); } }

6.注意

服务器返回需要加上这个，否则会遇到前端页面不执行返回的JavaScript脚本的问题

Response.ContentType = "text/html;charset=UTF-8";

配置完成即可使用图片上传功能
