App中的Web.Config配置錯誤

Question

我已准備好將應用程序上傳到托管，但是當我在服務器上傳文件時，我收到此錯誤：

'/'應用程序中的服務器錯誤。

配置錯誤

描述：處理為此請求提供服務所需的配置文件時發生錯誤。 請查看下面的具體錯誤詳細信息並相應地修改配置文件。

分析器錯誤消息：此配置部分不能在此路徑中使用。 當站點管理員使用繼承的配置文件中的<location allowOverride =“false”>鎖定對此節的訪問權限時，會發生這種情況。

來源錯誤：

服務器上發生應用程序錯誤。 此應用程序的當前自定義錯誤設置可防止遠程查看應用程序錯誤的詳細信息（出於安全原因）。 但是，它可以由運行在本地服務器計算機上的瀏覽器查看。

托管服務台說他們無法更改服務器配置，因此我的web.config文件如下：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location allowOverride="true">
  <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Lampino.mdf;Integrated Security=True" providerName="System.Data.SqlClient"/>
  </connectionStrings>

    <system.web>
      <globalization uiCulture="pl-PL" culture="pl-PL" fileEncoding="utf-8" responseEncoding="utf-8" requestEncoding="utf-8"/>
      <compilation debug="true"/>
      <customErrors mode="Off"/>
      <securityPolicy>
        <trustLevel name="Full"/>
      </securityPolicy>
    </system.web>
  </location>
</configuration>

有沒有選擇它可以在這個托管上工作或我應該找到一個新的？ 也許我的web.config文件確實存在問題？

它與解決IIS問題的方式相同，但沒有任何改變。 此外，我無權訪問服務器配置...

編輯：當我刪除trustLevel標簽時收到此錯誤消息：

Server Error in '/' Application.

Answer 1

當前版本的ASP.NET現在只支持完全信任。您需要找到支持完全信任的托管服務提供商。 例如asphostportal或hostforlife

Answer 2

要使用.mdf ，你需要有充分的信任級別文件（見這里的細節，在實體框架和通用Providers部分）。

您的托管服務提供商不允許您更改信任級別，因此使用<trustLevel name="Full"/>指令會導致原始錯誤。

刪除<trustLevel name="Full"/>指令解決了原始錯誤，但是由於您的Web應用程序仍需要運行完全信任級別（主機提供商不提供），因此您會收到安全性異常。

Answer 3

write \\ in connectionstring.

 <connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=(LocalDB)\\v11.0;AttachDbFilename=|DataDirectory|\\Lampino.mdf;Integrated Security=True" providerName="System.Data.SqlClient"/>
  </connectionStrings>
