c# - 代码访问安全和 Sharepoint WebParts

Question

我对代码访问安全性在 Sharepoint 中的工作方式有一个模糊的了解。

我开发了一个自定义 Web 部件并在我的 list 中设置了 CAS 策略

<CodeAccessSecurity>
<PolicyItem>
  <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for Okana">
    <IPermission class="Microsoft.SharePoint.Security.SharePointPermission, Microsoft.SharePoint.Security, Version=12.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" version="1" ObjectModel="True" Impersonate="True" />
    <IPermission class="SecurityPermission" version="1" Flags="Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration" />
    <IPermission class="AspNetHostingPermission" version="1" Level="Medium" />
    <IPermission class="DnsPermission" version="1" Unrestricted="true" />
    <IPermission class="EventLogPermission" version="1" Unrestricted="true">
      <Machine name="localhost" access="Administer" />
    </IPermission>
    <IPermission class="EnvironmentPermission" version="1" Unrestricted="true" />
    <IPermission class="System.Configuration.ConfigurationPermission, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" version="1" Unrestricted="true"/>
    <IPermission class="System.Net.WebPermission, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" />
    <IPermission class="System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" Unrestricted="true" />
    <IPermission class="System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true" PathDiscovery="*AllFiles*" />
    <IPermission class="IsolatedStorageFilePermission" version="1" Allowed="AssemblyIsolationByUser" UserQuota="9223372036854775807" />
    <IPermission class="PrintingPermission" version="1" Level="DefaultPrinting" />
    <IPermission class="PerformanceCounterPermission" version="1">
      <Machine name="localhost">
        <Category name="Enterprise Library Caching Counters" access="Write"/>
        <Category name="Enterprise Library Cryptography Counters" access="Write"/>
        <Category name="Enterprise Library Data Counters" access="Write"/>
        <Category name="Enterprise Library Exception Handling Counters" access="Write"/>
        <Category name="Enterprise Library Logging Counters" access="Write"/>
        <Category name="Enterprise Library Security Counters" access="Write"/>
      </Machine>
    </IPermission>
    <IPermission class="ReflectionPermission" version="1" Unrestricted="true"/>
    <IPermission class="SecurityPermission" version="1" Flags="SerializationFormatter, UnmanagedCode, Infrastructure, Assertion, Execution, ControlThread, ControlPrincipal, RemotingConfiguration, ControlAppDomain,ControlDomainPolicy"  />
    <IPermission class="SharePointPermission" version="1" ObjectModel="True" />
    <IPermission class="SmtpPermission" version="1" Access="Connect" />
    <IPermission class="SqlClientPermission" version="1" Unrestricted="true"/>
    <IPermission class="WebPartPermission" version="1" Connections="True" />
    <IPermission class="WebPermission" version="1">
      <ConnectAccess>
        <URI uri="$OriginHost$"/>
      </ConnectAccess>
    </IPermission>
  </PermissionSet>
  <Assemblies>
     ....
  </Assemblies>

当它被部署到 Sharepoint 服务器上时，它被正确地转换成一个 wss_custom_wss_minimaltrust.config 并且大部分工作。

为了让 WebPart 完全工作，但是我发现我需要在部署后手动修改 wss_custom_wss_minimaltrust.config 并在权限集上设置 Unrestricted="true"

 <PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1">

到

<PermissionSet class="NamedPermissionSet" version="1" Description="Permission set for MyApp" Name="mywebparts.wsp-86d8cae1-7db2-4057-8c17-dc551adb17a2-1" Unrestricted="true">

这都是因为我正在从 Web 部件加载用户控件。我不相信有一种方法可以使用 CAS 来实现这一点，但我愿意被证明是错误的。

有没有办法在 list 中设置一些东西，这样我就不需要手动修复了？

谢谢

您的 web 部件是否在 bin 文件中？

您是否在程序集中设置了部分信任的调用方？

如果不这样做!这是最佳实践。
