IIS 在 Powershell 中启用 HTTP Keep-Alive答案

http://technet.microsoft.com/en-us/library/cc772183(v=ws.10).aspx 页面解释了如何启用 HTTP Keep-Alive 响应标头 (IIS 7)

我想在 WMI 的 Powershell 中执行此操作

上面写着：

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

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

【解决方案1】：

要发现特定命名空间中的类，试试这个

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

要找到匹配项，请执行此操作

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();

然后您可以执行类似的操作来获取 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()

【解决方案2】：

您也可以使用Set-WebConfiguration cmdlet 进行设置：

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

非常感谢，谢伊。我最终使用了这个解决方案，尽管它不像我最初询问的那样基于 WMI。像我这样的新手需要运行的唯一一件事是：Import-Module WebAdministration。此外，可能以下命令更简单： Set-WebConfigurationProperty "/system.webServer/httpProtocol" -name allowKeepAlive -value "true"
是的，我应该提到 Import-Module :)
我收到“在此对象上找不到属性 'AllowKeepAlive'。验证该属性是否存在并且可以设置。”一切似乎都很好。想法？ AllowKeepAlive 属性 bool AllowKeepAlive {get;set;}
