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="/UploadFiles/2021-04-02/ckeditor.js">

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"htmlcode">

/// <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
