asp.net-mvc - 使用 ASP.NET MVC 上传( session 和身份验证)

Question

当我对 uplodify ( http://www.uploadify.com/ ) 使用的操作或 Controller 使用授权过滤器时，无法访问该操作...

此外， session 不会被检索。

我发现这是为了检索用户 session :

但是如何将其与[Authorize]过滤器和检索的 session 一起使用？

为了纠正这个问题，我向您建议一个解决方案...使用 uploadify 发送身份验证 cookie 值和 session id cookie 值，并在检索 session 之前重新创建它。

这是在 View 中实现的代码:

<script>
    var auth = "<% = Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value %>";
    var ASPSESSID = "<%= Session.SessionID %>";

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

然后在 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);
    }

瞧，用这种方法它是完全透明的。

希望对大家有帮助!! ;)

编辑:使用 formData 而不是 scriptData
