为什么ASP.NET FormsAuthentication饼干不是认证用户？

问题描述

我有一个使用默认的SqlMembershipProvider和FormsAuthentication的网站。我可以使用内置的登录控制和/或在程序调用的所有方法来验证用户，并得到同样的结果 - 用户进行身份验证和cookie被创建，但因为我可以cookie不似乎是有效的吨得到进入需要身份验证的任何页面。

I have a site that uses the default SqlMembershipProvider and FormsAuthentication. I can use the built-in Login Controls and/or programmatically call all the methods to authenticate a user and get the same result - the user is authenticated and a cookie is created, but the cookie does not appear to be valid since I can't get into any page that requires authentication.

有没有真正的code，以显示默认的登录控制，因为它应该只是工作，但这里是自定义code我尝试：

There is no real code to show for the default Login Control since it should just "work", but here is the custom code I tried:

protected void ctrlLogin_Authenticate(object sender, AuthenticateEventArgs e)
{
   if (Membership.ValidateUser(ctrlLogin.UserName, ctrlLogin.Password))
   {
      FormsAuthentication.RedirectFromLoginPage(ctrlLogin.UserName, ctrlLogin.RememberMeSet);
      /*
       * I also tried this:
      FormsAuthentication.SetAuthCookie(ctrlLogin.UserName, ctrlLogin.RememberMeSet);
      if (!String.IsNullOrEmpty(Request.QueryString["ReturnUrl"]))
         Response.Redirect(Request.QueryString["ReturnUrl"]);
      Response.Redirect("/index.aspx");
       */
   }
   else
   {
      ctrlLogin.FailureText = "Invalid Username/Password Combination";
   }
}

有了这个code， Membership.ValidateUser（）成功，无一不 FormsAuthentication.RedirectFromLoginPage（）和FormsAuthentication.RedirectFromLoginPage（）成功设置cookie - 这饼干只是不工作来验证我的身份验证。我已删除我的所有Cookie，看着他们得到与FireCookie再次创造证实了这一点。 cookie的名称匹配什么，我有我的web.config，域名为/，并如预期的到期日（见下文）。

With this code, Membership.ValidateUser() succeeds, and both FormsAuthentication.RedirectFromLoginPage() and FormsAuthentication.RedirectFromLoginPage() successfully set a cookie - that cookie just doesn't work to verify my authentication. I have confirmed this by deleting all my cookies and watching them get created again with FireCookie. The cookie name matches what I have in my web.config, the domain is "/", and the expiration date is as expected (see below).

下面是我的web.config的有关章节：

Here are the relevant sections of my web.config:

<authentication mode="Forms">
  <forms loginUrl="~/login/index.aspx" name=".SoeAuth" protection="All"
    slidingExpiration="true" timeout="525599" domain=""></forms>
</authentication>
<membership defaultProvider="SqlMembershipProvider">
  <providers>
    <add connectionStringName="[MY_CS]" applicationName="[MY_APPNAME]"
      minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0"
      enablePasswordReset="true" passwordFormat="Hashed" requiresUniqueEmail="true"
      name="SqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider"
      requiresQuestionAndAnswer="false"/>
  </providers>
</membership>

应当注意的是，我还添加在我的web.config文件中的machineKey条目基于从a非常类似的问题在这里（没有解决我的问题）。此外，以供参考，超时= 525599以上不到一年的时间为1分钟我的持久cookie。

It should be noted that I also added a machineKey entry in my web.config file based on a suggestion from a very similar question here (which didn't solve my problem). Also, for reference, the timeout=525599 above is 1 minute less than a year for my persistent cookies.

推荐答案

我发现这个问题：

由于我是能够创建具有完全相同的源$ C ​​$ C简单的工作测试项目，我确定，问题是在web.config文件中。

Since I was able to create a simple working test project with the exact same source code, I determined that the problem was in the web.config file.

要通过每个部分，我在'的System.Web /的HttpModules部分我有一个＆LT发现元素。这样取出＆LT;添加名称=FormsAuthenticationTYPE =System.Web.Security.FormsAuthenticationModule/＆GT; 在计算机级别的web.config文件中定义的模块。添加回在瞬间解决了这一问题。

Going through each section, I discovered in the 'system.web / httpModules' section I had a <clear/> element. This removed the <add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule"/> module defined in machine-level web.config file. Adding it back in instantly fixed the problem.

的这肯定将是很好得到一个错误信息，当我试图使用FormsAuthentication方法和模块甚至没有加载中... 的
