最近在玩 asp.net core，不想用UEditor，想使用CKEditor。故需要图片上传功能。
废话不多说，先上效果图：
CKEditor 前端代码：
<text id="content" name="content"></text>
<script>
CKEDITOR.replace('content');
</script>
CKeditor config.js 配置代码：需要配置图片上传路径
CKEDITOR.editorConfig = function( config ) {
// Define changes to default configuration here. For example:
// config.language = 'fr';
// config.uiColor = '#AADC6E';
config.baseHref = "http://" + location.host;
config.filebrowserImageUploadUrl = '/Upload/UploadImage';
config.font_names = '宋体/宋体;黑体/黑体;楷体/楷体;幼圆/幼圆;微软雅黑/微软雅黑;' + config.font_names;
config.allowedContent = true;
};
如上代码，我们使用UploadController的UploadImage方法来处理上传事件。
服务端代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Hosting;
using System.IO;
using Ratuo.Common;
namespace Ratuo.Web.Controllers
{
public class UploadController : Controller
{
private IHostingEnvironment _env;
public UploadController(IHostingEnvironment env)
{
_env = env;
} public async Task<IActionResult> UploadImage()
{
string callback = Request.Query["CKEditorFuncNum"];//要求返回值
var upload = Request.Form.Files[];
string tpl = "<script type=\"text/javascript\">window.parent.CKEDITOR.tools.callFunction(\"{1}\", \"{0}\", \"{2}\");</script>";
if (upload == null)
return Content(string.Format(tpl, "", callback, "请选择一张图片！"), "text/html");
//判断是否是图片类型
List<string> imgtypelist = new List<string> { "image/pjpeg", "image/png", "image/x-png", "image/gif", "image/bmp" };
if(imgtypelist.FindIndex(x=>x == upload.ContentType) == -)
{
return Content(string.Format(tpl, "", callback, "请上传一张图片！"), "text/html");
}
var data = Request.Form.Files["upload"];
string filepath = _env.WebRootPath+"\\userfile\\images";
string imgname = Utils.GetOrderNum() + Utils.GetFileExtName(upload.FileName);
string fullpath = Path.Combine(filepath, imgname);
try
{
if (!Directory.Exists(filepath))
Directory.CreateDirectory(filepath);
if (data != null)
{
await Task.Run(() =>
{
using (FileStream fs = new FileStream(fullpath, FileMode.Create))
{
data.CopyTo(fs);
}
});
}
}
catch (Exception ex)
{
return Content(string.Format(tpl, "", callback, "图片上传失败："+ ex.Message), "text/html");
}
return Content(string.Format(tpl, "/userfile/images/" + imgname, callback, ""), "text/html");
}
}
}
编译，预览一下。即可！
