使用PowerShell脚本从Teamcity构建生成更改日志文件时出错

Question

我使用以下脚本从teamcity构建生成更改日志。

<#
.SYNOPSIS
    Generates a project change log file.
.LINK
    Script posted over:
    http://open.bekk.no/generating-a-project-change-log-with-teamcity-and-powershell
#>

# Where the changelog file will be created
$outputFile = "%system.teamcity.build.tempDir%\releasenotesfile_%teamcity.build.id%.txt"
# the url of teamcity server
$teamcityUrl = "%teamcity.serverUrl%"
# username/password to access Teamcity REST API
$authToken=[Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes("%system.teamcity.auth.userId%:%system.teamcity.auth.password%"))
# Build id for the release notes
$buildId = %teamcity.build.id%

# Get the commit messages for the specified change id
# Ignore messages containing #ignore
# Ignore empty lines
Function GetCommitMessages($changeid)
{
    $request = [System.Net.WebRequest]::Create("$teamcityUrl/httpAuth/app/rest/changes/id:$changeid")     
$request.Headers.Add("AUTHORIZATION", "$authToken");
$xml = [xml](new-object System.IO.StreamReader $request.GetResponse().GetResponseStream()).ReadToEnd()    
Microsoft.PowerShell.Utility\Select-Xml $xml -XPath "/change" |
    where { ($_.Node["comment"].InnerText.Length -ne 0) -and (-Not $_.Node["comment"].InnerText.Contains('#ignore'))} |
    foreach {"+ $($_.Node["user"].name) : $($_.Node["comment"].InnerText.Trim().Replace("`n"," "))`n"}
}

# Grab all the changes
$request = [System.Net.WebRequest]::Create("$teamcityUrl/httpAuth/app/rest/changes?build=id:$($buildId)")
$request.Headers.Add("AUTHORIZATION", "$authToken");
$xml = [xml](new-object System.IO.StreamReader $request.GetResponse().GetResponseStream()).ReadToEnd()

# Then get all commit messages for each of them
$changelog = Microsoft.PowerShell.Utility\Select-Xml $xml -XPath "/changes/change" | Foreach {GetCommitMessages($_.Node.id)}
$changelog > $outputFile
Write-Host "Changelog saved to ${outputFile}:"
$changelog

当我运行它时，会生成文件，但它始终为空。当我查看构建日志时，我看到PowerShell构建步骤中出现以下错误消息。

任何人都可以告诉我出了什么问题以及我需要改变什么来使这一步有效吗？

使用teamcity版本10观察到这些错误。  将Add（＆＃34; AUTHORIZATION＆＃34;，＆＃34; $ authToken＆＃34;）替换为  添加（＆＃34; AUTHORIZATION＆＃34;，＆＃34; Basic $ authToken＆＃34;）

这些代码适用于我的版本10，版本号为50574。
