uploadify Cookie 验证登入上传问题

浏览数：27 / 时间：2015年06月09日

上传文件时必须验证是否已登入。

当用FormsAuthentication做登入，使用FormsAuthentication.FormsCookieName进行验证是否已登入即可。

<script type="text/javascript">
var auth = "@(Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty :
 Request.Cookies[FormsAuthentication.FormsCookieName].Value)";   
    $(window).load(
    function () {
        $("#fileuploader").fileUpload({
            ‘uploader‘: ‘/Scripts/uploader.swf‘,
            ‘cancelImg‘: ‘/Images/cancel.png‘,
            ‘buttonText‘: ‘Select Image‘,
            ‘script‘: ‘Home/Upload‘,
            ‘folder‘: ‘/uploads‘,
            ‘fileDesc‘: ‘Image Files‘,
            ‘fileExt‘: ‘*.jpg;*.jpeg;*.gif;*.png‘,
            ‘multi‘: true,
            ‘auto‘: true,
            scriptData: { token: auth }
        });
    }
);
    </script>

<div id="fileuploader"></div>

        [HttpPost]
        public string Upload(HttpPostedFileBase fileData, string token)
        {
            if (string.IsNullOrEmpty(token))
            {
                return "noLogin";
            }
            FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(token);
            if (ticket != null)
            {
                var identity = new FormsIdentity(ticket);
                if (identity.IsAuthenticated)
                {
                    var fileName = this.Server.MapPath("~/uploads/" + System.IO.Path.GetFileName(fileData.FileName));
                    fileData.SaveAs(fileName);
                }
            }
            return "ok";
        }
