用msdeploy替换web.config中的连接字符串

Question

我想用msdeploy和powershell替换远程计算机上托管的iis服务的web.config中的connectionString。

脚本运行没有出错时：

$iisPath = "$iisServicePath,computerName=$computerName,userName=$userName,password=$password" 

& "C:\Program Files\IIS\Microsoft Web Deploy V3\msdeploy.exe" ` 
"-source=contentPath=$iisPath" ` 
'-verb=sync' ` 
'-verbose' ` 
'-allowUntrusted' ` 
"-dest=contentPath=$iisPath" ` 
'-setParam=kind=TextFile,match="configuration/connectionStrings/add[@name=MyEntities]/@connectionString",scope=web\.config$,value="$newConString"'; 

脚本的详细输出说：

Verbose: The synchronization completed in 1 pass(es). 
Total changes: 0 (0 added, 0 deleted, 0 updated, 0 parameters changed, 0 bytes copied) 

ConnectionString中Attribute`s值不会被替换。

我该怎么做？

UPDATE

这是错误消息我现在得到：

Verbose: Parameter entry 'MSDeploySetParameter-2080747909/1' could not be applied to 'MyWebSite/MyService\Web.config'. Deployment will continue with the original data. Details: 
No matches were found for the search string '`"configuration/connectionStrings/add[@name=MyEntities]/@connectionString`' (type 'TextFile'). 
Verbose: Attribute 'size' equality changed to False when comparing filePath (MyWebSite/MyService\Web.config) to MyWebSite/MyService\Web.config because of rule Parameterizat 
ion. 
Verbose: Source filePath (MyWebSite/MyService\Web.config) does not match destination (MyWebSite/MyService\Web.config) differing in attributes (parameters). Update pending. 
Verbose: Source filePath (MyWebSite/MyService\Web.config) replaced with changed attributes (size['3710','3707']) because of rule Parameterization. 
Info: Updating file (MyWebSite/MyService\Web.config). 
Verbose: The dependency check 'DependencyCheckInUse' found no issues. 
Verbose: The synchronization completed in 2 pass(es). 
Total changes: 1 (0 added, 0 deleted, 1 updated, 0 parameters changed, 3707 bytes copied) 

有了这个改变代码：

& "C:\Program Files\IIS\Microsoft Web Deploy V3\msdeploy.exe" ` 
"-source=contentPath=$iisPath" ` 
'-verb=sync' ` 
'-verbose' ` 
'-allowUntrusted' ` 
"-dest=contentPath=$iisPath" ` 
'-setParam=kind=TextFile,match=`"configuration/connectionStrings/add[@name=MyEntities]/@connectionString`",scope=web\.config$,value=`"$newConString`"';

更改这里的最后一行，你使用单引号，这将被精确解释为键入（例如，它不会交换变量的值）

我已经用双引号取代了你的单引号，并且继续前进，并逃脱了内引号。如果这不起作用，请告诉我！

-setParam=kind=TextFile,match=`"configuration/connectionStrings/add[@name=MyEntities]/@connectionString`",scope=web\.config$,value=`"$newConString`" ";
