【Hello CC.NET】自動化發布時 Web.config 文件維護

本文轉載自   查看原文   2013-08-02 18:30   2002    CruiseControl.NET/ CC.NET/ CI/ 批處理/ Continuous integration

在 《【Hello CC.NET】CC.NET 實現自動化集成》 的 HellowWorld 中經實現：

1.獲取源碼

2.編譯項目

3.集成測試

4.Ftp發布項目

5.創建安裝包

6.郵件通知

在方案落地的過程中，FTP 上傳開發自測環境（或測試環境）后，仍然需要人手來修改相關配置（比如 Web.config）。

假設項目的 Web.config 配置如下：

  <appSettings>
    <add key="OrgDB" value="xxx_dev_db"/>
    <add key="BusinessDB" value="xxx_DEV_DB"/>
    <add key="RedisCache" value="192.168.10.111:6379"/>
    <add key="SSOService" value="http://192.168.10.111/DEV/V1.1.9/SSOService.svc"/>
    <add key="Coder" value="蔡海華"/>
  </appSettings>

 在發布到測試環境之前，我們需要把 _dev_db 替換為 _test_db，192.168.10.111:6379 替換為 192.168.10.112：6379 ，http://192.168.10.111/DEV/V1.1.9/SSOService.svc 替換為 http://192.168.10.111/Test/V1.1.9/SSOService.svc（忽略大小寫）。

 

一、用 bat 腳本實現文件拷貝和web.config內容替換

1.文件拷貝

為了不影響舊的環境，我們新建一個文件夾 PackageDirectory 來保存修改后的文件。

文件拷貝用批處理來實現：新建一個 txt 文件，輸入以下內容，另存為 DFCopier.bat（directories & files copier），copyfrom 和 copyto 由參數方式傳入。

@echo off  
set from=%1
set to=%2

::rd /q/s "%to%"&&md "%to%"
dir /a /b %to%|findstr .>nul 2>nul && goto havefiles || goto nofiles  
      
:havefiles  
rem echo 有文件  
goto end 
      
:nofiles  
rem echo 沒有文件  
XCOPY %from% %to% /c/q/e/r
:end

 

2.文件內容替換

新建一個 txt 文件，輸入以下內容，另存為 FCReplacer.bat（file content replacer），directory , file, from, to 由參數方式傳入。

@echo off
set dir=%1
set file=%2
set from=%3
set to=%4

setlocal enabledelayedexpansion
pushd %dir%
for /f "tokens=1,2* delims=:" %%i in ('findstr /n ".*" %file%') do (
    set txt=%%j
    if "!txt!" == "" (
        echo.>>%dir%%file%.tmp
    ) else (
        echo !txt:%from%=%to%!>>%dir%%file%.tmp
    )
)
move /y %dir%%file%.tmp %file%
:end

3.配置 ccnet.config

在 tasks 節點中添加以下兩個子節點。假設一個最簡單的場景：替換數據庫命名 xxx_dev_db 為 xxx_test_db。

      <!-- 復制文件到 Package 目錄 -->
      <exec>
        <executable>C:\CC.NET\Server\DFCopier.bat</executable>
        <buildArgs>C:\CC.NET\Server\Test\PublishDirectory C:\CC.NET\Server\Test\PackageDirectory</buildArgs>
      </exec>
      <!-- 替換 Package 目錄下的 WebConfig 文件 -->
      <exec>
        <executable>C:\CC.NET\Server\FCReplacer.bat</executable>
        <buildArgs>C:\CC.NET\Server\Test\PackageDirectory\WcfService Web.config _dev_db _test_db</buildArgs>
      </exec>

ftp 和 package 部分修改如下：

      <!--ftp發布Wcf服務到開發環境-->
      <ftp>
        <serverName>127.0.0.1</serverName>
        <userName>admin</userName>
        <password>admin</password>
        <action>UploadFolder</action>
        <ftpFolderName></ftpFolderName>
        <localFolderName>C:\CC.NET\Server\Test\PackageDirectory\WcfService</localFolderName>
        <recursiveCopy>true</recursiveCopy>
        <timeDifference>1</timeDifference>
      </ftp>
      <package>
        <name>Lib.sln</name>
        <compression>9</compression>
        <manifest type="defaultManifestGenerator" />
        <packageList>
          <packageFile sourceFile="C:\CC.NET\Server\Test\PackageDirectory\WcfService\*.svc" targetFolder="WcfService" />
          <packageFile sourceFile="C:\CC.NET\Server\Test\PackageDirectory\WcfService\*.Release.config" targetFolder="WcfService" />
          <packageFile sourceFile="C:\CC.NET\Server\Test\PackageDirectory\WcfService\bin\*.dll" targetFolder="WcfService\bin" />
          <!--<packageFolder sourceFolder="C:\CC.NET\Server\Test\PublishDirectory\WcfService" targetFolder="WcfService" 
                         fileFilter="*.*" flatten="false" includeSubFolders="false" />-->
        </packageList>
      </package>

 

4.測試

Forcebuild 得到以下結果（只截取了 DFCopier.bat 和 FCReplacer.bar 相關的部分）：

打開 Web.config 文件卻發現中文會變成亂碼。

二、自己實現文件內容替換功能

批處理的方式在中文面前顯得有點蒼白無力，另外一些更復雜的場景是無法簡單地 replace 來解決。一番 Google 折騰后我決定自己寫一個 replacer，支持正則來處理可能出現的復雜需求。

1.實現 replacer

新建一個項目，命名為 FCReplacer。實現的代碼 100 行不到。編譯得到 FCReplacer.exe

    class Program
    {
        static void Main(string[] args)
        {
            var file = GetFileName(args);
            var replacers = GetReplaers(args);

            if (file == null || replacers == null || replacers.Count() == 0)
                return;

            var txt = File.ReadAllText(file);

            Console.WriteLine(string.Format("Replace content of file({0})", file));
            foreach (var replacer in replacers)
            {
                Console.WriteLine(string.Format("Replace {0} to {1}", replacer.From, replacer.To));
                txt = replacer.Replace(txt);
            }
            File.WriteAllText(file, txt);
        }
        static string GetFileName(string[] args)
        {
            string filename = null;
            var fileRegex = new Regex("^/file=(=?.*)$", RegexOptions.Compiled);
            foreach (var arg in args)
            {
                var match = fileRegex.Match(arg); 
                if (match.Groups.Count == 2)
                {
                    filename = match.Groups[1].Value.Trim();
                    break;
                }
            }
            return filename;
        }
        static IEnumerable<Replacer> GetReplaers(string[] args)
        {
            var list = new List<Replacer>();
            var replacerRegex = new Regex("^/from=(=?.*)/to=(=?.*)$", RegexOptions.Compiled);
            foreach (var arg in args)
            {
                var match = replacerRegex.Match(arg);
                if (match.Groups.Count == 3)
                {
                    var from = match.Groups[1].Value.Trim();
                    var to = match.Groups[2].Value.Trim();
                    list.Add(new Replacer() { From = from, To = to });
                }
            }
            return list;
        }
        class Replacer
        {
            public string From { get; set; }
            public string To { get; set; }
            public string Replace(string txt, RegexOptions regexOption = RegexOptions.IgnoreCase)
            {
                txt = Regex.Replace(txt, this.From, this.To, regexOption);
                return txt;
            }
        }
    }

 

 

2.配置 ccnet.config

把文件替換的批處理部分改為 FCReplacer.exe。替換的邏輯通過參數方式傳入。假設三個更復雜的場景：

（1） 替換數據庫名 xxx_dev_db 為 xxx_test_db

（2）替換 redis 緩存服務的地址 192.168.10.111:PORT 為 192.168.10.112:PORT，端口設置不變

（3）替換 SSO 服務地址，版本號不變

      <!-- 復制文件到 Package 目錄 -->
      <exec>
        <executable>C:\CC.NET\Server\DFCopier.bat</executable>
        <buildArgs>C:\CC.NET\Server\Test\PublishDirectory C:\CC.NET\Server\Test\PackageDirectory</buildArgs>
      </exec>
      <!-- 替換 Package 目錄下的 WebConfig 文件 -->
      <!--<exec>
        <executable>C:\CC.NET\Server\FCReplacer.bat</executable>
        <buildArgs>C:\CC.NET\Server\Test\PackageDirectory\WcfService Web.config _dev_db _test_db</buildArgs>
      </exec>-->
      <exec>
        <executable>C:\CC.NET\Server\FCReplacer.exe</executable>
        <buildArgs> /file=C:\CC.NET\Server\Test\PackageDirectory\WcfService\Web.config
 /from=_dev_db/to=_test_db
 /from=http://192.168.10.111/Dev/V(=?\d+(.\d+)*)/SSOService.svc/to=http://192.168.10.111/Test/V$1/SSOService.svc
        </buildArgs>
      </exec>

 

3.測試

Forcebuild 得到以下結果（只截取了 DFCopier.bat 和 FCReplacer.exe 相關的部分）：

打開 Web.config 文件，三個替換邏輯都已經實現，中文也不再是亂碼。

 

完整的 ccnet.config 配置如下：

到這里，一個簡單場景的自動化發布部分已經實現。TODO 列表里仍須解決的幾個主要問題：

1.Build 成功，人工測試未通過時，如何一鍵回滾

2.數據庫的更新和回滾如何實現自動化
