Question

我有一个ASP.NET MVC 5应用程序在开发机器上运行良好。我发布了它并在线传输了文件，它会产生以下错误：

<html>

<head>
  <title>Test App</title>
  <style>
    li {
      list-style: none;
    }
    ul {
      background-color: green;
    }
  </style>
</head>

<body>
  <ul class="nav">
    <li>
      George
    </li>

    <li>
      Belly
    </li>

    <li>
      Mac
    </li>
  </ul>
</body>

</html>

我的托管为我提供了一个ASP.NET设置面板。

我的设置如下：

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request failed.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

任何人都可以指导我这是什么问题。它是应用程序还是主机？

Answer 1

大多数托管服务提供商现在都提供FULL Trust托管服务。 MVC不接受部分信任。

<system.web>
     <trust level="Full" />
   </system.web>

如果这不起作用如果您无权访问服务器，请联系您的托管服务提供商。

我们所做的是在我们的开发中运行以下内容。

<system.web>
  <trust level="Medium"/>
</system.web>

更改信任级别会导致登台环境失败并显示共享主机上显示的相同错误，因此您可以更正代码以符合主机要求。如果您要部署到中等信任托管环境，最好将信任级别设置为“预先中等”，以节省时间和精力。
