使用powershell修改web.config

Question

我需要尝试更新web.config文件以更改web.config的IP地址我已经包含了代码部分我正在寻找powershell来编写更改脚本.

<connectionStrings>
    <add name="connectionString" connectionString="provider=SQLOLEDB;Server=192.168.1.100;database=sample;Trusted_Connection=Yes" providerName="System.Data.OleDb" />
    <add name="sqlConnectionString" connectionString="Data Source=192.168.1.100;Initial Catalog=sample;Trusted_Connection=Yes" providerName="System.Data.SqlClient" />
  </connectionStrings>

我想要一个非常简单的解决方案,只需更新ServerIP地址即可.

任何人都知道使用PowerShell执行此操作的简单方法.

Answer 1

我想到以下几点

$cfg = [xml](gc web.config)
# Replace all references of the IP in all connection string
$cfg.configuration.connectionStrings.add|%{
   $_.connectionString = $_.connectionString -replace "192.168.1.100", "1.0.0.1";
}
$cfg.Save("Web.config");

如果您只是想要替换特定的连接字符串,我会像这样获取它:

$con= $cfg.configuration.connectionStrings.add|?{$_.name -eq "SqlDataCon"};
# Replace the content
$con.connectionString = $con.connectionString -replace "192.168.1.100", "1.0.0.1"

Answer 2

你可以试试 ：

$xml = [xml](Get-Content c:\temp\web.config)
$conString = $xml.connectionStrings.add[0].connectionString
$conString2 = $conString -replace '192.168.1.100','10.10.10.10'
$xml.connectionStrings.add[0].connectionString = $conString2
$conString = $xml.connectionStrings.add[1].connectionString
$conString2 = $conString -replace '192.168.1.100','10.10.10.10'
$xml.connectionStrings.add[1].connectionString = $conString2
$xml.Save('c:\temp\web2.config')

这将完成两个连接字符串的工作。如果您不想对旧的IP地址进行硬编码，则可以使用：

$conString -replace 'Server=.*;','Server=10.10.10.11;'
