SpwebConfigModification类将不会更新Central Admin Application的Web.config文件

Question

使用SharePoint 2010，我正在尝试使用SpwebConfigModification类在农场中的应用程序上对Web.config文件进行一些基本更改，包括Central Adminissment.Config Files使用Web应用程序范围范围文件，并使用功能接收器处理添加/删除的功能修改：

public override void FeatureActivated(SPFeatureReceiverProperties properties)
    {
        SPWebApplication webApp = properties.Feature.Parent as SPWebApplication;
        String ownerId = properties.Feature.DefinitionId.ToString();
        List<SPWebConfigModification> modsToAdd = new List<SPWebConfigModification>();

        #region Authentication Providers

        modsToAdd.Add(new SPWebConfigModification()
        {
            Name = "defaultProvider",
            Owner = ownerId,
            Path = "configuration/system.web/membership",
            Sequence = 0,
            Type = SPWebConfigModification.SPWebConfigModificationType.EnsureAttribute,
            Value = "FBA_AD_MP"
        });

        modsToAdd.Add(new SPWebConfigModification()
        {
            Name = "add [@name=\"FBA_AD_MP\"] [@type=\"System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a\"] [@connectionStringName=\"ADFBAConnectionString\"] [@enableSearchMethods=\"true\"] [@attributeMapUsername=\"userPrincipalName\"]",
            Owner = ownerId,
            Path = "configuration/system.web/membership/providers",
            Sequence = 0,
            Type = SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode,
            Value = "<add name=\"FBA_AD_MP\" type=\"System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a\" connectionStringName=\"ADFBAConnectionString\" enableSearchMethods=\"true\" attributeMapUsername=\"userPrincipalName\" />"
        });

        #endregion

        #region Connection Strings

        modsToAdd.Add(new SPWebConfigModification()
        {
            Name = "connectionStrings",
            Owner = ownerId,
            Path = "configuration",
            Sequence = 0,
            Type = SPWebConfigModification.SPWebConfigModificationType.EnsureSection,
            Value = "<connectionStrings />"
        });

        modsToAdd.Add(WebConfigModificationsUtility.CreateConnectionStringModification(ownerId, 1, "ADFBAConnectionString", properties.Feature.Properties["ADFBAConnectionString"].Value));

        #endregion

        WebConfigModificationsUtility.AddWebConfigModifications(webApp, modsToAdd.ToArray());
    }

WebConconfigmodificationutility类是这些功能接收器共享的简单实用程序：

public static void AddWebConfigModifications(SPWebApplication webApp, params SPWebConfigModification[] modificationsToAdd)
    {
        AddWebConfigModifications(webApp, true, modificationsToAdd);
    }
public static void AddWebConfigModifications(SPWebApplication webApp, Boolean persistChanges, params SPWebConfigModification[] modificationsToAdd)
    {
        foreach (SPWebConfigModification curMod in modificationsToAdd)
        {
            SPWebService.ContentService.WebApplications[webApp.Id].WebConfigModifications.Add(curMod);                
        }

        if (persistChanges)
        {
            PersistWebConfigModifications(webApp);
        }
    }
public static void PersistWebConfigModifications(SPWebApplication webApp)
    {
        SPWebService.ContentService.WebApplications[webApp.Id].Update();                        
        SPWebService.ContentService.ApplyWebConfigModifications();
    }

一切都在内容应用程序上正常工作，但是在尝试激活中央管理Web应用程序上的功能时，SpwebConfigmodificaiton项目从未写入Web.config文件。我已经验证了该代码正在执行无例外。此外，我的功能接收器尝试删除任何修改时都对停用了任何修改：

public override void FeatureDeactivating(SPFeatureReceiverProperties properties)
        {
            SPWebApplication webApp = properties.Feature.Parent as SPWebApplication;
            String ownerId = properties.Feature.DefinitionId.ToString();
            WebConfigModificationsUtility.RemoveWebConfigModifications(webApp, ownerId);
        }
public static void RemoveWebConfigModifications(SPWebApplication webApp, String ownerId, Boolean persistChanges)
        {            
            RemoveWebConfigModifications(webApp, persistChanges, webApp.WebConfigModifications.Where(x => x.Owner == ownerId).ToArray());
        }
public static void RemoveWebConfigModifications(SPWebApplication webApp, Boolean persistChanges, params SPWebConfigModification[] modificationsToRemove)
        {
            foreach (SPWebConfigModification curMod in modificationsToRemove)
            {
                SPWebService.ContentService.WebApplications[webApp.Id].WebConfigModifications.Remove(curMod);                
            }

            if (persistChanges)
            {
                PersistWebConfigModifications(webApp);
            }
        }

当此代码在中央管理Web应用程序上运行时，它会发现功能激活中创建的四个修改并成功地删除它们，但是 两者都不 这些操作实际上正在更改Web应用程序的web.config文件；它甚至没有触摸，最后编辑日期的时间戳记在整个过程中保持不变。

我发现各种博客都在谈论SpwebConfigModification类的继承棘手，其中大多数问题都是使用名称和所有者属性正确地适当地解决了使用SpweBservice静态属性的正确更改，但是我可以告诉我，我可以告诉我我关注的是所有推荐的做法。我开始怀疑API中有一个错误，但是我想知道是否有人成功地在SharePoint 2010中成功地做到了这一点，或者我是否应该破解打开反射器并尝试查看给出的东西？

Answer 1

我只是从Stack Overflow中收到了一条通知，我根据视图获得了这个问题的徽章，我什至不记得在Spoverflow上问这个问题，因为当时它并不真正存在。

关键是，我还问了这个问题，并在那里得到了正确的答案：

“就像ContentService一样，SpweBservice也有一个管理对象，该对象还具有WebApplications Collection。使用induranceService来获取您的Centraladmin Web应用程序。”

我假设该功能是Web应用程序范围的。

您是否正在通过浏览器（Central Admin）激活该功能？

尝试从PowerShell/stsadm激活它。我总是发现，如果我尝试从使用web.config的过程中修改web.config，事情似乎会变得不好。

function New-WebConfigMod {
    param(
        [Parameter(Mandatory=$true, ValueFromPipeline=$true, Position=0)][Microsoft.SharePoint.PowerShell.SPWebApplicationPipeBind]$WebApplication,
        [string]$path,
        [string]$name,
        [string]$owner,
        [string]$value,         
        [Microsoft.SharePoint.Administration.SPWebConfigModification+SPWebConfigModificationType]$type=[Microsoft.SharePoint.Administration.SPWebConfigModification+SPWebConfigModificationType]::EnsureChildNode
    )
    process {       
        $WebApp = $WebApplication.Read()

        $mod = New-Object Microsoft.SharePoint.Administration.SPWebConfigModification 
        $mod.Path = $path;
        $mod.Name = $name;
        $mod.Sequence = 0;
        $mod.Owner = $owner;
        $mod.Type = $type;
        $mod.Value = $value;        
        $WebApp.WebConfigModifications.Add($mod) 
        $WebApp.Update() 
        $WebApp.WebService.ApplyWebConfigModifications();

        $WebApplication
    } 
} 

Get-SPWebApplication -IncludeCentralAdministration |? {
        $_.Url -eq "http://xyz:8080/"
    } | New-WebConfigMod -path "configuration" -name "connectionStrings" -owner "connectionStrings" -value "<connectionStrings></connectionStrings>" | 
        out-null

或将其转换为您的功能

webApp.WebConfigModifications.Add(curMod);
webApp.Update();
webApp.WebService.ApplyWebConfigModifications();

不确定，但是尝试使用此代码...

    public static void AddWebConfigModifications(SPWebApplication webApp, Boolean persistChanges, params SPWebConfigModification[] modificationsToAdd)    
    {
    foreach (SPWebConfigModification curMod in modificationsToAdd)
        {          
        webApp.WebConfigModifications.Add(curMod);
        webApp.Update();
        webApp.Farm.Services.GetValue<spwebservice></spwebservice>().ApplyWebConfigModifications();  
    }
