Godaddy 上的 Asp.net MVC 5 网站托管：System.Security.SecurityException

Question

我使用带有 .netframework 4.5.2 的 Visual Studio 2015 创建了一个网站。该网站在本地机器上运行良好，但是当我上传了在 Godaddy 中发布网站时。首先我得到错误自定义错误需要关闭。我添加了标签来解决这个问题。

<customErrors mode="Off"/>

然后我收到信任权限错误“System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed” . 我google了一下，发现需要在服务器的web.config和asp.net设置中将信任级别设置为full。 我在 Godaddy 服务器和 web.config 设置中将 CAS 信任级别设置为完全，但仍然无法正常工作。

<trustLevel name="Full" policyFile="internal"/> 

我收到内部服务器错误。 我又试了一次，还是同样的错误。

<securityPolicy>
    <trustLevel name="Full" policyFile="internal"/>
 </securityPolicy>

我不确定需要对 web.config 文件进行哪些更改才能正常工作。请找到我的 web.config

我是否缺少 web.config 的某些设置？

Answer 1

你必须清除 system.Codedom 删除该部分并添加<system.codedom/>

这对我有用

Answer 2

你应该做几件事来找出问题

1) 检查连接字符串是否包含“integrated Security=true”，如果为真则表示网站尝试使用windows凭据连接数据库，尽量不要使用windows凭据

2）如果这不能解决问题，则暂时打开自定义错误，然后浏览网站，它应该会给出一些有意义的错误消息
