Question

I am automating SQL Reporting services and i need to add proxy settings to the web.config file. I try to do this in powershell but i am unable to figure out how to do this through powershell.

I need to add the following piece of xml code to the end of an existing web.config XML file

  <system.net>
    <defaultProxy enabled="true" useDefaultCredentials="true">
      <proxy bypassonlocal="True" proxyaddress="http://ocs.kennisnet.nl:3128" />
    </defaultProxy>
  </system.net>

The complete xml file needs to be:

I found a lot of code examples but none seem to work, i managed to create bellow code but it doesn't save the file, and i don't know how to add the second key values. Hopefully one of you are more skilled in this than i am ..

$file="web.config"
[xml]$xmlDoc = [System.Xml.XmlDocument](Get-Content $file)

$newEl=$xmlDoc.CreateElement("system.net")
$xmlDoc.configuration.AppendChild($newEl)  
$xmlDoc.Save($file)

$newEl=$xmlDoc.CreateElement("defaultProxy")   
$nameAtt1=$xmlDoc.CreateAttribute("enabled")
$nameAtt1.psbase.value="true"  
$newEl.SetAttributeNode($nameAtt1)  

$nameAtt2=$xmlDoc.CreateAttribute("useDefaultCredentials")  
$nameAtt2.psbase.value="true"    
$newEl.SetAttributeNode($nameAtt2) 
$xmlDoc.configuration["system.net"].AppendChild($newEl)  

$xmlDoc.Save($file)

The eventual result need to create the complete XML file as shown above.

Please help...

Answer 1

以下内容将在运行时元素之后插入新的XML数据：

$webconfig = [xml](Get-Content C:\temp\web.config)
$newxml = [xml](Get-Content c:\temp\new.xml)

$newNode = $webconfig.ImportNode($newxml.'system.net',$true)
$InsertAfterNode = $webconfig.configuration.runtime
$null = $webconfig.configuration.insertAfter($newNode,$InsertAfterNode)
$webconfig.Save("c:\temp\web.config")

$newNode存在，因此我们拥有InsertAfter()方法的正确对象类型。相应的ImportNode()方法输出我们想要的对象类型。 $true被传递，以便我们导入system.net的所有后代元素。

在处理文件时，我使用了完整路径。我相信.Save()方法通常需要完整路径，因为它默认为特定目录。请注意，这不是通用代码，它取决于您专门提供要从中插入新数据的元素。

还有一种使用XElement的方法。

using namespace "System.Xml.Linq"
Add-Type -AssemblyName System.Xml.Linq

$configPath = Convert-Path "web.config"
$newElement = [XElement]@'
  <system.net>
    <defaultProxy enabled="true" useDefaultCredentials="true">
      <proxy bypassonlocal="True" proxyaddress="http://ocs.kennisnet.nl:3128" />
    </defaultProxy>
  </system.net>
'@

$configuration = [XElement]::Load($configPath)
$configuration.Add($newElement)
$configuration.ToString() | Out-File "new.config"

Answer 3

我最终做了以下事情：

$newXml = @'
  <system.net>
    <defaultProxy enabled="true" useDefaultCredentials="true">
      <proxy bypassonlocal="True" proxyaddress="http://ocs.kennisnet.nl:3128" />
    </defaultProxy>
  </system.net>
</configuration>
'@

$File = ".\web.config" 

# Remove last line of file
$Content = Get-Content $File
$Output = $Content[0..($Content.count - 2)]

Out-File -FilePath $File -InputObject $Output

# Add code block to file
Add-Content -Path ".\web.config" -Value $newXml

这不是最好的选择，因为我假设文件的最后一行始终是相同的，但它肯定对我有用。

糟糕的是，我无法像rokumaru所建议的那样使代码正常工作，因为这将是最好的用法，我希望他会补充此代码以使其正常工作。
