如何在我的连接字符串上使用 Web.Config 转换? [英] How do I use Web.Config transform on my connection strings?

问题描述

在我当前的项目中，我有一些对本地开发机器有效的连接字符串:

<预><代码><配置><连接字符串><添加名称=应用服务"connectionString="Data Source=localhost;Initial Catalog=MyDB;Integrated Security=SSPI"</connectionStrings>....</配置>

我将如何使用 Web.Config 转换将此表达式转换为对我们的生产服务器有效的表达式?生产服务器看起来像:

<预><代码><配置><连接字符串><添加名称=应用服务"connectionString="Data Source=IPAddress,Port;Initial Catalog=SomeOtherDB;User ID=TopSecretUsername;Password=SecurePassword"</connectionStrings>....</配置>

语法对我来说并不明显，而且我完全无法理解 页面.

解决方案

这对我有用，但我也发现它有时有点古怪.您将需要创建另一个名为 Web.Config.Release 的文件并用以下内容填充它:

<配置xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"><连接字符串><add name="local" connectionString="Data Source=IPAddress,Port;Initial Catalog=SomeOtherDB;User ID=TopSecretUsername;Password=SecurePassword"xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/></connectionStrings><system.web><编译xdt:Transform="RemoveAttributes(debug)"/></system.web><应用设置><add key="default_db_connection" value="local" xdt:Transform="SetAttributes" xdt:Locator="Match(key)"/></appSettings></配置>

In my current project, I have some connection strings that are valid for local development machines:

<configuration>
  <connectionStrings>
    <add name="ApplicationServices"
         connectionString="Data Source=localhost;Initial Catalog=MyDB;Integrated Security=SSPI"
  </connectionStrings>
....
</configuration>

How would I use the Web.Config transforms to convert from this expression to one valid for our production server? The production server one would look something like:

<configuration>
  <connectionStrings>
    <add name="ApplicationServices"
         connectionString="Data Source=IPAddress,Port;Initial Catalog=SomeOtherDB;User ID=TopSecretUsername;Password=SecurePassword"
  </connectionStrings>
....
</configuration>

The syntax isn't obvious to me, and I'm completely failing at grokking the page on it.

解决方案

This works for me but I too have found it to be a bit flakey at times. You will need to create another file called Web.Config.Release and fill it with the following:

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

  <connectionStrings>
    <add name="local" connectionString="Data Source=IPAddress,Port;Initial Catalog=SomeOtherDB;User ID=TopSecretUsername;Password=SecurePassword" 
    xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
  </connectionStrings>

  <system.web>
    <compilation xdt:Transform="RemoveAttributes(debug)" />

  </system.web>
    <appSettings>
        <add key="default_db_connection" value="local" xdt:Transform="SetAttributes" xdt:Locator="Match(key)" />
    </appSettings>
</configuration>
