【问题描述】：

我正在使用以下脚本从 teamcity 构建中生成变更日志。

<#
.SYNOPSIS
    Generates a project change log file.

#>

# 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，但它始终是空的。当我查看构建日志时，我在 powershell 构建步骤中看到以下错误消息。

谁能告诉我出了什么问题以及我需要进行哪些更改才能使此步骤生效？

【问题讨论】：

查看 TeamCity REST api 文档时，没有任何关于 Authorization 标头的内容。他们只提到用户/密码身份验证。
所以你是说我应该使用用户名和密码而不是那些变量？

【解决方案1】：

在 teamcity 版本 10 上观察到这些错误。将 Add("AUTHORIZATION", "$authToken") 替换为 Add("AUTHORIZATION", "基本 $authToken")

这些代码适用于我的版本 10，内部版本号为 50574。
