怎么在asp.net core中利用CKEditor实现一个图片上传功能?相信很多没有经验的人对此束手无策,为此本文总结了问题出现的原因和解决方法,通过这篇文章希望你能解决这个问题。
1.visual studio 2019 开发环境
2.net core 2.0 及以上版本
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"] = "富文本框"; 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" rel="external nofollow" > <i class="orange ace-icon fa fa-cog bigger-120"></i> 发邮件 </a> </li> <li class="active"> <a href="javascript:void(0);" rel="external nofollow" > <i class="green ace-icon fa fa-home bigger-120"></i> 富文本编辑框 </a> </li> </ul> </div> <!-- /.box-header --> <!-- form start --> <form role="form" id="form1"> <div class="box-body"> <div class="callout callout-success"> <h5>富文本编辑器</h5> <p></p> </div> <table class="form"> <tr> <th class="formTitle">内容</th> <td class="formValue"> @Html.EditorFor(model => model.rules) @*<textarea class="form-control" name="Text" id="Text" placeholder=""></textarea>*@ </td> </tr> </table> </div> <!-- /.box-body --> <div class="box-footer"> <button type="button" id="btnSave" class="btn btn-success">保存</button> </div> </form> </div> <!-- /.tab-content --> </section> @section scripts{ <script src="~/ckeditor/ckeditor.js"></script> <script src="~/js/jquery.base64.js"></script> <script type="text/javascript"> //editor.document.getBody().getText(); //取得纯文本 //editor.document.getBody().getHtml(); //取得html文本 //var editor = CKEDITOR.replace('Text', //{ // toolbar: "Full", // filebrowserUploadUrl: "/Image/ckupload?type=File", //开启文件上传(此项会同时开启图片和FLASH上传) // filebrowserImageUploadUrl: "/Image/ckupload?type=Images", // 开启图片上传 // filebrowserFlashUploadUrl: "/Image/ckupload?type=Flash" //开启FLASH上传 //}); $.base64.utf8encode = true; var editor2 = CKEDITOR.replace('rules', { toolbar: "Full", filebrowserUploadUrl: "/Image/ckupload?type=File", //开启文件上传(此项会同时开启图片和FLASH上传) filebrowserImageUploadUrl: "/Image/ckupload?type=Images", // 开启图片上传 filebrowserFlashUploadUrl: "/Image/ckupload?type=Flash" //开启FLASH上传 }); $(function () { editor2.setData("@(Html.Raw(Model.rules))"); }); $("#btnSave").click(function (ev) { var a = editor2.document.getBody().getHtml(); $("#rules").val( $.base64.btoa(a) ); var $form = $("#form1"); editor2.setData(a); $.ajax({ url: "/demo/ck/", data: $form.serialize(), type: "POST", cache: false, async: false, beforeSend: function () { $("#btnSave").attr("disabled", "disabled"); }, success: function (r) { // if (r.isSucceeded == true) { // location.href = r.goBackUrl;// "/Employee/index?ram=" + Math.random();// r.GoBackUrl; // } // else // 其他问题 // { alert( $.base64.atob(r.message, true)); // } $("#btnSave").removeAttr("disabled"); }, error: function () { alert("保存失败"); $("#btnSave").removeAttr("disabled"); } }); // alert(editor2.document.getBody().getHtml()); // return; //$.post("/demo/ck/", // { // Text: editor2.document.getBody().getHtml(), // }, // function (data, status) { // alert("Data: " + data + "\nStatus: " + status); // }); }); </script> }
/// <summary> /// 富文本框 上传图片 /// </summary> /// <returns></returns> [HttpPost] [IgnoreAuthorize] public IActionResult Ckupload() { uploadfile user = new uploadfile(); var files = Request.Form.Files; if (files == null || files.Count == 0) ViewBag.cc = "no file"; user.ShareImg = files[0]; var contentRoot = Directory.GetCurrentDirectory(); var webRoot = Path.Combine(contentRoot, "wwwroot"); var parsedContentDisposition = ContentDispositionHeaderValue.Parse(user.ShareImg.ContentDisposition); var originalName = parsedContentDisposition.FileName.ToString().Replace("\"", ""); var ext = Path.GetExtension(Path.Combine(webRoot, originalName)); // if (ext != ".jpg") // return Json(new { jsonrpc = "2.0", error = new { code = 101, message = "文件格式错误" }, id = "id" }); string gid = Guid.NewGuid().ToString(); var fileName = Path.Combine("upload", gid + ext); var fileName2 = "upload/" + gid + ext; using (var stream = new FileStream(Path.Combine(webRoot, fileName), FileMode.CreateNew)) { user.ShareImg.CopyTo(stream); } string output = @"<script type=""text/javascript"">window.parent.CKEDITOR.tools.callFunction({0} ,'{1}');</script>"; 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
