我有一个 PowerShell 脚本，它调用 TeamCity 的 REST API 进行备份。

这个脚本工作在 v7.1 上，但是当我升级到 8.0.5 时，脚本停止工作。

脚本：

$ErrorActionPreference = 'Stop'

function Execute-HTTPPostCommand()
 {
    param(
        [string] $url
    )

    $webRequest = [System.Net.WebRequest]::Create($url)
    $webRequest.ContentType = "text/html"
    $PostStr = [System.Text.Encoding]::Default.GetBytes("")
    $webrequest.ContentLength = $PostStr.Length
    $webrequest.AuthenticationLevel = [System.Net.Security.AuthenticationLevel]::MutualAuthRequested
    $webrequest.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials
    $webRequest.Method = "POST"

    $requestStream = $webRequest.GetRequestStream()
    $requestStream.Write($PostStr, 0, $PostStr.length)
    $requestStream.Close()

    [System.Net.WebResponse] $resp = $webRequest.GetResponse();
    $rs = $resp.GetResponseStream();
    [System.IO.StreamReader] $sr = New-Object System.IO.StreamReader -argumentList $rs;
    [string] $results = $sr.ReadToEnd();

    return $results;
}

function Execute-TeamCityBackup()
 {
    param(
        [string] $server,
        [string] $addTimestamp,
        [string] $includeConfigs,
        [string] $includeDatabase,
        [string] $includeBuildLogs,
        [string] $includePersonalChanges,
        [string] $fileName
    )
    $TeamCityURL = [System.String]::Format("{0}/app/rest/server/backup?addTimestamp={1}&includeConfigs={2}&includeDatabase={3}&includeBuildLogs={4}&includePersonalChanges={5}&fileName={6}",
                                            $server,
                                            $addTimestamp,
                                            $includeConfigs,
                                            $includeDatabase,
                                            $includeBuildLogs,
                                            $includePersonalChanges,
                                            $fileName);
    Write-Host "URL: " $TeamCityURL
    Execute-HTTPPostCommand $TeamCityURL
}


$server = "http://localhost"
$addTimestamp = $true
$includeConfigs = $true
$includeDatabase = $true
$includeBuildLogs = $true
$includePersonalChanges = $true
$fileName = "TeamCity_Backup_"

Execute-TeamCityBackup $server $addTimestamp $includeConfigs $includeDatabase $includeBuildLogs $includePersonalChanges $fileName

这将失败并显示消息“远程服务器返回错误：(500) 内部服务器错误”。

我已经在 Web 浏览器（ntlm 提示符）中测试了脚本运行的凭据，并且 TC 站点加载没有问题。

任何想法我做错了什么？

根据文档，您可以使用基本身份验证。

http://confluence.jetbrains.com/display/TCD8/REST+API#RESTAPI-RESTAuthentication

这应该可以代替 Execute-HTTPPostCommand。

Invoke-RestMethod -Uri $url -Method Post -UseDefaultCredentials
