如何通过VSTS版本定义覆盖Windows Services .exe.config文件中的键 [英] How to override the keys in windows services .exe.config file through VSTS release definition

问题描述

我正在处理用于部署Windows Services Project的VSTS发布任务.不幸的是，我们没有为创建放置文件夹创建任何构建定义. 但是，我的客户将为此项目提供放置文件夹，我需要的是发布级别的我想覆盖现有.exe.config文件的键".

I am working on VSTS release task for deploying the Windows Services Project. Unfortunately, we are not creating any Build Definition for creating drop folder. But, my client will provide drop folder for this project, what I need is "I want to override the keys of an existing .exe.config file" at release level.

对于创建Windows Services部署任务，我遵循了以下 Windows服务扩展程序

For creating the Windows Services Deploy task,I followed this Windows Services Extension

例如，我的放置文件夹如下所示:

For example my drop folder looks like below:

非常感谢您提供此参考资料 article ，这对于使用Power Shell命令更改配置文件中的值非常有用.我对此参考链接表示怀疑: 例如，如果有这样的代码:

Many thanks for this reference article and It's a very useful for changing values in config file using Power Shell commands. I have doubt in from that reference link : For Example, If had a Code like this :

<erecruit.tasks>
<tasks>
  <task name="AA" taskName="AA">
    <parameters>
      <param key="connectionString">Server="XXXX"</param>
    </parameters>
</task>

如何更改上面的连接字符串值?

推荐答案

您可以在

安装发布管理实用程序任务扩展

添加带有XPath/正则表达式任务的Tokenizer以释放定义(指定源文件名和配置Json文件名)

配置文件示例:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <appSettings>
      <add key="TestKey1" value="__Token1__" />
      <add key="TestKey2" value="__Token2__" />
      <add key="TestKey3" value="__Token3__" />
      <add key="TestKey4" value="__Token4__" />
    </appSettings>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />
    </startup>
</configuration>

配置Json文件(默认环境是发行版definitioin中的环境名称):

Configuration Json file (Default Environment is the environment name in release definitioin):

{
   "Default Environment":{
      "CustomVariables":{
         "Token2":"value_from_custom2",
         "Token3":"value_from_custom3"
      },
      "ConfigChanges":[
         {
            "KeyName":"/configuration/appSettings/add[@key='TestKey1']",
            "Attribute":"value",
            "Value":"value_from_xpath"
         }
      ]
   }
}

然后TestKey1(键)的值将与value_from_xpath相关，而TestKey2和TestKey3的值将与value_from_custom2和value_from_custom3相关.

Then the value of TestKey1 (key) will be related to value_from_xpath and the values of TestKey2 and TestKey3 will be related to value_from_custom2 and value_from_custom3.

另一方面，如果您未指定Configuration Json文件名，则可以直接使用发布变量.

On the other hand, you can use release variables directly if you don’t specify Configuration Json filename.

例如，您的配置文件中有__TokenVariable1__，发行版本定义中有TokenVariable1 release/environment变量，则__TokenVariable1__将通过 Tokenizer 任务替换.

For example, there is __TokenVariable1__ in your config file and TokenVariable1 release/environment variable in release definition, then the __TokenVariable1__ will be replaced through Tokenizer task.

相关文章:更新:

您还可以直接通过PowerShell进行操作.

You also can do it through PowerShell directly.
