【问题描述】：

我的uploadify (v.2.1.4) 和我的MVC 3 项目存在配置问题。这是返回 HTTP 302 代码的代码。

        @{string auth = @Request.Cookies[FormsAuthentication.FormsCookieName] == null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value;}

        $("#fileuploader").uploadify({
            uploader: '@Url.Content("~/Scripts/uploadify.swf")',
            script: '@Url.Action("Upload", "Control")',
            scriptData: { token: "@auth" },
            fileDataName: 'file',
            buttonText: 'Upload file',
            multi: false,
            sizeLimit: 22222222222,
            simUploadLimit: 1,
            cancelImg: '@Url.Content("~/Images/uploadify-cancel.png")',
            auto: true,
            onError: function(event, queueID, fileObj, errorObj) {
                alert("Error!!! Type: [" + errorObj.type + "] Info [" + errorObj.info + "]");
            },
            onComplete: function (event, queueId, fileObj, response, data) {
                alert(response);
            }
        });

public class ControlController : Controller
{        
    [HttpPost]        
    public ActionResult Upload(string token, HttpPostedFileBase file)
    {
        if (file != null && file.ContentLength > 0)
        {
            var appData = Server.MapPath("~/app_data");
            var filename = Path.Combine(appData, Path.GetFileName(file.FileName));
            file.SaveAs(filename);
        }
        return Json(true);
    }
}

1) 控制器的动作没有被触发

2) 我找到了该主题 Getting Uploadify to work with asp.net-mvc，但如果我将该属性用于我的控制器，我会看到“AuthenticationToken”为空（我已登录）

3) 如果我将上传选项“method”设置为“post”，我会得到#2032 error

编辑

控制器是管理控制器，所以我使用该属性：

    protected override bool AuthorizeCore(HttpContextBase httpContext) {

        if (!HttpContext.Current.User.Identity.IsAuthenticated)
            return false;

        if (admin && !um.IsAdmin(HttpContext.Current.User.Identity.Name))
            return false;

        return true;
    }

返回真。我注意到，如果我删除此属性，则上传开始工作。但我需要那个属性

【解决方案1】：

it's help you.
var auth = "@(Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value)";
    var ASPSESSID = "@(Session.SessionID)";

    $("#uploadifyLogo").uploadify({
        ...
        'scriptData': { 'ASPSESSID': ASPSESSID, 'AUTHID': auth  }
    });

在 Global.asax 中：

protected void Application_BeginRequest(object sender, EventArgs e)
    {
      /* we guess at this point session is not already retrieved by application so we recreate cookie with the session id... */
        try
        {
            string session_param_name = "ASPSESSID";
            string session_cookie_name = "ASP.NET_SessionId";

            if (HttpContext.Current.Request.Form[session_param_name] != null)
            {
                UpdateCookie(session_cookie_name, HttpContext.Current.Request.Form[session_param_name]);
            }
            else if (HttpContext.Current.Request.QueryString[session_param_name] != null)
            {
                UpdateCookie(session_cookie_name, HttpContext.Current.Request.QueryString[session_param_name]);
            }
        }
        catch
        {
        }

        try
        {
            string auth_param_name = "AUTHID";
            string auth_cookie_name = FormsAuthentication.FormsCookieName;

            if (HttpContext.Current.Request.Form[auth_param_name] != null)
            {
                UpdateCookie(auth_cookie_name, HttpContext.Current.Request.Form[auth_param_name]);
            }
            else if (HttpContext.Current.Request.QueryString[auth_param_name] != null)
            {
                UpdateCookie(auth_cookie_name, HttpContext.Current.Request.QueryString[auth_param_name]);
            }

        }
        catch
        {
        }
    }

    private void UpdateCookie(string cookie_name, string cookie_value)
    {
        HttpCookie cookie = HttpContext.Current.Request.Cookies.Get(cookie_name);
        if (null == cookie)
        {
            cookie = new HttpCookie(cookie_name);
        }
        cookie.Value = cookie_value;
        HttpContext.Current.Request.Cookies.Set(cookie);
    }
