【Kindeditor编辑器】文件上传、空间管理

包括图片上传、文件上传、Flash上传、多媒体上传、空间管理（图片空间、文件空间等等）

一、编辑器相关参数

二、简单的封装类

这里只是做了简单的封装，欢迎大家指点改正。

三、使用

    public JsonResult Upload(RequestUploadMessage model)
    {
        model.savePath = String.Format(@"f:\richtextbox\{0}\", model.dir.ToString());
        model.webUrl = String.Format("http://localhost:52527/richtextbox/{0}/", model.dir.ToString());
        ResponseUploadMessage result = KindeditorHelper.Upload(model);
        return Json(result, JsonRequestBehavior.DenyGet);
    }

    public JsonResult FileManager(RequestManageMessage model)
    {
        model.webUrl = String.Format("http://localhost:52527/richtextbox/{0}/", model.dir.ToString());
        model.savePath = String.Format(@"f:\richtextbox\{0}\", model.dir.ToString());

        ResponseManageMessage result = KindeditorHelper.Manage(model);
        return Json(result, JsonRequestBehavior.AllowGet);
    }
