Question

页面http://technet.microsoft.com/en-us/library/cc772183(v=ws.10).aspx说明了如何启用HTTP保持活动响应标头（IIS 7）

我想通过WMI Powershell 执行此操作

它说：

使用以下WMI类，方法或属性来执行此操作程序： HTTPProtocolSection.AllowKeepAlive 属性

我试过了：

PS > Get-WmiObject -Class HTTPProtocolSection
Get-WmiObject : Invalid class
At line:1 char:14
+ Get-WmiObject <<<<  -Class HTTPProtocolSection
    + CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], ManagementException
    + FullyQualifiedErrorId : GetWMIManagementException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

使用此HTTPProtocolSection类并启用AllowKeepAlive属性的正确方法是什么？

Answer 1

您还可以使用Set-WebConfiguration cmdlet设置它：

Set-WebConfiguration -Filter system.webServer/httpProtocol -PSPath MACHINE/WEBROOT/APPHOST -Value @{allowKeepAlive=$true}

Answer 2

要发现特定命名空间中的类，请尝试使用

PS c:\>Get-WmiObject -List * "root\webadministration"

并找到匹配执行此操作

PS c:\>Get-WmiObject -List * "root\webadministration" | Where-Object {$_.name -match "Http"}


PS C:\>Get-WmiObject -Namespace "root\webadministration" -class HttpProtocolSection | Get-Member

TypeName: System.Management.ManagementObject#root\webadministration\HttpProtocolSection

AllowKeepAlive      Property      bool AllowKeepAlive {get;set;}
CustomHeaders       Property      System.Management.ManagementObject#CustomHeaderSettings CustomHeaders {get;set;}
Location            Property      string Location {get;set;}
Path                Property      string Path {get;set;}
RedirectHeaders     Property      System.Management.ManagementObject#RedirectHeaderSettings RedirectHeaders {get;set;}
SectionInformation  Property      System.Management.ManagementObject#SectionInformation SectionInformation {get;set;}
__CLASS             Property      string __CLASS {get;set;}
__DERIVATION        Property      string[] __DERIVATION {get;set;}
__DYNASTY           Property      string __DYNASTY {get;set;}
__GENUS             Property      int __GENUS {get;set;}
__NAMESPACE         Property      string __NAMESPACE {get;set;}
__PATH              Property      string __PATH {get;set;}
__PROPERTY_COUNT    Property      int __PROPERTY_COUNT {get;set;}
__RELPATH           Property      string __RELPATH {get;set;}
__SERVER            Property      string __SERVER {get;set;}
__SUPERCLASS        Property      string __SUPERCLASS {get;set;}
ConvertFromDateTime ScriptMethod  System.Object ConvertFromDateTime();
ConvertToDateTime   ScriptMethod  System.Object ConvertToDateTime();

然后你可以做这样的事情来获得AllowKeepAlive

的值

PS C:\> (get-wmiobject -namespace "root\webadministration" -class HttpProtocolSection).AllowKeepAlive 
True

PS C:\>$a = Get-WmiObject -Namespace "root\webadministration" -class HttpProtocolSection
PS C:\>$a.AllowKeepAlive = $false
PS C:\>$a.Put()

IIS在Powershell中启用HTTP Keep-Alive
