錯誤。在處理新的asp.net mvc4錯誤的請求時發生錯誤，找不到sql server？

我創建了一個新的asp.net mvc4應用程序。我創建了一個控制器聊天和查看聊天。錯誤。在處理新的asp.net mvc4錯誤的請求時發生錯誤，找不到sql server？

public class ChatController : Controller 
    { 
     // 
     // GET: /Chat/ 

     public ActionResult Index() 
     { 
      return View(); 
     } 

    }

我不會粘貼聊天視圖，因爲我不認爲它與錯誤無關。

在LoginPartial.cshtml我有這樣的：

@if (Request.IsAuthenticated) { 
    <text> 
     Hello, @Html.ActionLink(User.Identity.Name, "Manage", "Account", routeValues: null, htmlAttributes: new { @class = "username", title = "Manage" })! 
     @Html.ActionLink("Dashboard", "Index", "Dashboard", routeValues: null, htmlAttributes: new { id = "dashboard" }) 
     @Html.ActionLink("Chat", "Index", "Chat", routeValues: null, htmlAttributes: new { id = "chat" }) 

     @using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm" })) { 
      @Html.AntiForgeryToken() 
      <a href="javascript:document.getElementById('logoutForm').submit()">Log off</a> 
     } 
    </text> 
} else { 
    <ul> 
     <li>@Html.ActionLink("Register", "Register", "Account", routeValues: null, htmlAttributes: new { id = "registerLink" })</li> 
     <li>@Html.ActionLink("Log in", "Login", "Account", routeValues: null, htmlAttributes: new { id = "loginLink" })</li> 
    </ul> 
}

瀏覽到應用程序和登錄電子後，我點擊聊天，我也得到一個：錯誤。處理您的請求時發生錯誤。

通過使用NLOG我得到這個，我真的不知道是什麼代碼試圖連接到SQL，因爲聊天控制器沒有任何服務器端代碼做任何查詢

在web.config有這個，我檢查了App_data文件夾和MDF文件在那裏。

<connectionStrings> 
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-FullStackSampleApplication-20130404120217;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-FullStackSampleApplication-20130404120217.mdf" providerName="System.Data.SqlClient" /> 
    </connectionStrings>

UPDATE： 通過檢查我的web.config，我看到elmah.axd取決於用戶和角色是受保護的，但沒有角色提供的任何地方，

<location path="elmah.axd" inheritInChildApplications="false"> 
    <system.web> 
     <httpHandlers> 
     <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" /> 
     </httpHandlers> 
     <authorization> 
     <allow roles="admin" /> 
     <allow users="levalencia" /> 
     <deny users="*" /> 
     </authorization> 
    </system.web> 
    <system.webServer> 
     <handlers> 
     <add name="ELMAH" verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" preCondition="integratedMode" /> 
     </handlers> 
    </system.webServer> 
    </location>

是Web配置設置爲使用窗體身份驗證？ – asawyer 2013-04-10 18:24:48

是的。 – 2013-04-10 18:28:04

確保您的項目中有「aspnet-FullStackSampleApplication-20130404120217.mdf」無障礙。錯誤說明您的應用程序無法連接到SQL Server實例。 – HaBo 2013-04-10 18:29:19

這是我如何設法解決問題：

我把customErrors關閉。

<customErrors mode="Off" defaultRedirect="~/Error/General"> 
    <error statusCode="404" redirect="~/Error/Http404"/> 
    <error statusCode="403" redirect="~/Error/Http403"/>  
</customErrors>

然後我發現它試圖找到一個查看調用索引。

所以我改變了loginpartial.cshtml到

@Html.ActionLink("Chat", "Chat", "Chat", routeValues: null, htmlAttributes: new { id = "chat" })

我的錯誤被命名控制器和視圖。關於sql server的問題，我想應該是在應用程序中的其他東西在日誌上的某個地方。

它可能正在嘗試寫一個日誌來告訴你這個錯誤。你真的沒有解決我害怕的問題。 – asawyer 2013-04-10 19:24:03

+1將customErrors設爲Off – 2014-10-01 09:09:10

我解決了這個問題發表意見如下認證標籤：

<authentication mode="Forms"> 
    <forms loginUrl="~/Account/Login" timeout="2880" />
