Question

我有很多web.config文件。在哪个URL中包含计算机名称。

这是我的示例web.config文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.Model>
<client>
      <endpoint address="http://MyMachineName:80/MyProj/Core/NewService/SecurityObject.0/Secretservice.svc" binding="basicHttpBinding" bindingConfiguration="MyProj_Internal_Routing" behaviorConfiguration="UserSIDBehavior" contract="SecurityMgmt.SecurityMgmtContract" name="HttpEndpointSecMgt" />
      <endpoint address="http://MyMachineName:80/MyProj/Core/DataObject/SystemCatalogs1.0/DataObjectservice/DataObjectservice.svc" binding="basicHttpBinding" bindingConfiguration="MyProj_Internal_Routing" behaviorConfiguration="UserSIDBehavior" contract="DataObjectservice.SystemCatalogsDataObjectservice" name="BasicHttpBinding_SystemCatalogsDataObjectservice" />
      <endpoint address="http://MyMachineName:80/MyProj/Core/NewService/Movement.0/Movement.svc" binding="basicHttpBinding" bindingConfiguration="MyProj_Internal_Routing" behaviorConfiguration="UserSIDBehavior" contract="NavigationClientLib.NavigationNewService" name="BasicHttpBinding_NavigationNewService" />
 </client>

 <system.Model>

 </configuration>

当用户更改机器名称时，必须在所有xml文件中更新。

我决定写一个这样的函数。

    Function Update-MachineName ([string] $FilePath,[string] $xpath, [string] $NewMachineName="NewComputer") {


    # Get the config file contents
    $WebConfig = [XML] (Get-content $Filepath)

    #Find the url using xpath which has old Machine name 
    $hostnameString= Select-XML -XML $WebConfig -XPath $Xpath

    Foreach ( $hostname in $hostnameString) { 

           if ( ($hostname.Node.value -match 'http') -eq $true ) {

               $hostname.Node.value
               $MachineOldName = $($($hostname.Node.value.split("/"))[2].split(":"))[0]
               $MachineOldName

               $hostname.Node.value.replace( $MachineOldName,$NewMachineName)

           }
    }

 $WebConfig.Save($FilePath)
}

Update-MachineName "C:\web.config" "//@address"

虽然我用新的机器名替换，但web.config内容仍未更新。如何使用新计算机名称进行更新

Answer 1

如果只是替换上面提到的XML结构中的机器名，那么你真的不需要解析XML并使用XPath ......

$oldMachineName = "MyMachineName"
$newMachineName = "MyBrandNewMachineNAme"

$content = Get-Content -path $filePath
$content | foreach { $_.Replace($oldMachineName, $newMachineName) } | Set-Content $filePath

Answer 2

您的替换值未保存在节点上。改变这一行：

$hostname.Node.value.replace( $MachineOldName,$NewMachineName)

要

$hostname.Node.value=$hostname.Node.value.replace( $MachineOldName,$NewMachineName)

Answer 3

在您的功能中，您必须将文件保存回磁盘。您正在使用内存中的xml进行操作，因此更改只能在控制台中显示，而不能在实际文件中显示。

Answer 4

您可以这样使用：

$nodoEndpointSvcAddress = $($configXml.configuration.'system.serviceModel'.client.endpoint |  where { $_.name -eq "MyEndPoint1" })
[string]$endpointSvcAddress = $nodoEndpointSvcAddress.address
Write-Host $endpointSvcAddress

# Replace
$server = "test"
iif ($endpointSvcAddress.Contains($server))
{
    Write-Host "`r`nReplace $endpointSvcAddress"
    $nodoEndpointSvcAddress.address=$nodoEndpointSvcAddress.address.replace( $server,"PROSERVER")
    Write-Host ("Replaced " + $nodoEndpointSvcAddress.address)

}

$configXml.Save($pathCDR)
