如何使用app.config安装使用OctopusDeploy安装的Windows服务

Question

到目前为止，我已经能够创建一个Windows服务，然后我可以让TeamCity构建和打包该服务，并使其可用于Octopus Deploy。

我似乎不能做的是，有一个app.config，其中有一个连接字符串，并使用该连接字符串。

以下是我的Deploy.ps1：

# These variables should be set via the Octopus web portal:
#
#   ServiceName         - Name of the Windows service
# 
# sc.exe is the Service Control utility in Windows
# Default the service name
if (! $ServiceName)
{
    $ServiceName = "OctoService"
}
Write-Host "Service Name:" $ServiceName
# Get the exe name based ont the directory
$contentPath = (Join-Path $OctopusPackageDirectoryPath "content")
$configName = (Get-ChildItem $contentPath*.config -Name | Select-Object -First 1)
$binPath  = (Join-Path $OctopusPackageDirectoryPath "libnet40")
$exeName = (Get-ChildItem $binPath*.exe -Name | Select-Object -First 1)
$fullPath = (Join-Path $binPath $exeName)
Write-Host "Service Path:" $fullPath
Write-Host "Config Path:" (Join-Path $contentPath $configName)
Copy-Item (Join-Path $contentPath $configName) $binPath
$service = Get-Service $ServiceName -ErrorAction SilentlyContinue
if (! $service)
{
    Write-Host "The service will be installed"
    New-Service -Name $ServiceName -BinaryPathName $fullPath -StartupType Automatic
}
else
{
    Stop-Service $ServiceName -Force
    $fullPath = Resolve-Path $fullPath
    & "sc.exe" config "$ServiceName" binPath= $fullPath start= auto | Write-Host
    Start-Service $ServiceName
}

这是我的.nuspec文件：

<?xml version="1.0"?>
<package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
  <metadata>
    <id>$id$</id>
    <version>$version$</version>
    <title>$title$</title>
    <authors>$author$</authors>
    <owners>$author$</owners>
    <requireLicenseAcceptance>false</requireLicenseAcceptance>
    <description>$description$</description>
    <copyright>Copyright 2012</copyright>
  </metadata>
  <files>
    <file src="app.config" target="content" />
    <file src="Deploy.ps1" />
  </files>  
</package>

如果我尝试访问ConfigurationManager.ConnectionStrings["MyConnectionString"]，我会得到一个null引用。

有什么建议吗？

我的钱花在了你身上。你需要将你的app.config命名为exename.exe.config，这样你的服务就会收到它。

App.config是ide中使用的"临时"名称，作为构建的一部分，它将被重命名为任何exe名称
