SharePoint Online：使用 PowerShell 在所有站点上激活功能

要求：使用 PowerShell 为所有网站启用 SharePoint Online 功能。

使用 PowerShell 激活所有网站的网站集功能

您想要在所有 SharePoint Online 网站上激活该功能吗？在管理大量网站时，使用 PowerShell 激活 SharePoint Online 网站上的功能可以节省时间和精力。本指南将向您展示如何使用 PowerShell 激活所有 SharePoint Online 网站上的功能。我们需要为租户中的所有网站集启用 SharePoint Online“默认在客户端应用程序中打开文档”功能。

以下是为所有网站集启用一项功能的 PowerShell：


#Parameters
$TenantAdminURL = "https://Crescent-Admin.SharePoint.com"
#Site Collection feature "Open Documents in Client Applications by Default"
$FeatureId = "8a4b8de2-6fd8-41e9-923c-c7c3c00f8295" 

#Connect to Admin Center
$Cred = Get-Credential
Connect-PnPOnline -Url $TenantAdminURL -Credentials $Cred

#Get All Site collections - Exclude: Seach Center, Mysite Host, App Catalog, Content Type Hub, eDiscovery and Bot Sites
$SitesCollections = Get-PnPTenantSite | Where -Property Template -NotIn ("SRCHCEN#0", "REDIRECTSITE#0","SPSMSITEHOST#0", "APPCATALOG#0", "POINTPUBLISHINGHUB#0", "EDISC#0", "STS#-1")

#Loop through each site collection
ForEach($Site in $SitesCollections)
{
    #Connect to site collection
    Write-host -f Yellow "Trying to Activate the feature on site:"$Site.Url    
    Connect-PnPOnline -Url $Site.Url -Credentials $Cred

    #Get the Feature
    $Feature = Get-PnPFeature -Scope Site -Identity $FeatureId

    #Check if feature is activated
    If($Feature.DefinitionId -eq $null)
    {
        #Enable site collection feature
        Enable-PnPFeature -Scope Site -Identity $FeatureId -Force

        Write-host -f Green "`tFeature Activated Successfully!"
    }
    Else
    {
        Write-host -f Cyan "`tFeature is already active!"
    }
}

此 PowerShell 脚本会激活 SharePoint Online 租户中所有网站上的一项功能。如果您需要在多个站点上快速激活该功能，这会很有用。顺便说一句，您需要网站集管理员权限才能完成这些步骤。

使用 PowerShell 在 SharePoint Online 网站集的所有网站中启用网站功能

如果您想要在所有网站（包括给定网站集的根网站和子网站）上激活 Web 范围的功能，该怎么办？比如说，我们要在 SharePoint Online 网站集中的所有网站（网站）上激活“发布”功能。


#Parameters
$SiteURL = "https://crescent.sharepoint.com/sites/marketing"
$FeatureId = "94c94ca6-b32f-4da9-a9e3-1f3d343d7ecb" #Web Scoped Publishing Feature
 
#Function to Activate a Feature in SharePoint Online Web
Function Activate-PnPWebFeature
{ 
    [cmdletbinding()]
    Param(
        [parameter(Mandatory = $true, ValueFromPipeline = $True)] $Web,
        [parameter(Mandatory = $true, ValueFromPipeline = $False)] $FeatureId
    )
 
    Try {
        Write-host -f Yellow "Trying to Activate Feature on:"$web.Url
        #Get the Feature to activate
        $Feature = Get-PnPFeature -Scope Web -Identity $FeatureId -ErrorAction Stop
  
        #Check if the Feature is Activate
        If($Feature.DefinitionId -eq $null)
        {    
            #Activate feature            
            Enable-PnPFeature -Scope Web -Identity $FeatureId -Force -Verbose -ErrorAction Stop
  
            Write-host -f Green "`tFeature Activated Successfully!"
        }
        Else
        {
            Write-host -f Cyan "`tFeature is already active!"
        }
    }
    Catch {
        write-host "`tError Activating Feature: $($_.Exception.Message)" -foregroundcolor Red
    }
}
 
#Connect to the site collection
Connect-PnPOnline -Url $SiteURL -Interactive
 
#Call the Function for Root Web & all Subwebs
Get-PnPSubWeb -IncludeRootWeb -Recurse | ForEach-Object { Activate-PnPWebFeature $_ -FeatureId $FeatureId}

如果您的 Web 范围的功能对网站集功能有任何依赖性，您必须首先激活网站集功能！在我们的例子中，我们必须在网站集中激活发布功能，然后才能在所有网站上激活该功能。

PowerShell 在租户的所有站点上激活功能

如何为租户中的所有站点激活站点功能？以下 PowerShell 脚本在所有网站上启用给定功能，包括 SharePoint Online 租户中所有网站集的根网站及其子网站。


#Parameters
$TenantAdminURL = "https://Crescent-Admin.SharePoint.com"
$FeatureId = "a7a2793e-67cd-4dc1-9fd0-43f61581207a" #"Following Content" Web Scoped Feature
 
#Function to Activate a Web Feature in SharePoint Online
Function Activate-PnPWebFeature
{ 
    [cmdletbinding()]
    Param(
        [parameter(Mandatory = $true, ValueFromPipeline = $True)] $Web,
        [parameter(Mandatory = $true, ValueFromPipeline = $False)] $FeatureId
    )
 
    Try {
        Write-host -f Yellow "Trying to Activate Feature on:"$web.Url
        #Get the Feature to activate
        $Feature = Get-PnPFeature -Scope Web -Identity $FeatureId -ErrorAction Stop
 
        #Check if the Feature is Activate
        If($Feature.DefinitionId -eq $null)
        {
            #Activate the feature
            Enable-PnPFeature -Scope Web -Identity $FeatureId -Force -ErrorAction Stop 
            Write-host -f Green "`tFeature Activated Successfully!"
        }
        Else
        {
            Write-host -f Cyan "`tFeature is already active!"
        }
    }
    Catch {
        write-host "`tError Activating Feature: $($_.Exception.Message)" -foregroundcolor Red
    }
}
 
#Connect to Admin Center
$Cred = Get-Credential
Connect-PnPOnline -Url $TenantAdminURL -Credentials $Cred
 
#Get All Site collections - Exclude: Seach Center, Mysite Host, App Catalog, Content Type Hub, eDiscovery and Bot Sites
$SitesCollections = Get-PnPTenantSite | Where -Property Template -NotIn ("SRCHCEN#0", "REDIRECTSITE#0","SPSMSITEHOST#0", "APPCATALOG#0", "POINTPUBLISHINGHUB#0", "EDISC#0", "STS#-1")
 
#Loop through each site collection
ForEach($Site in $SitesCollections)
{
    #Connect to site collection
    $SiteConn = Connect-PnPOnline -Url $Site.Url -Credentials $Cred
 
    #Call the Function for Web & all Subwebs
    Get-PnPSubWeb -IncludeRootWeb -Recurse | ForEach-Object { Activate-PnPWebFeature $_ -FeatureId $FeatureId} 
}
