Team Foundation Server 2018 API构建定义错误

Question

我正在尝试使用Powershell 5.1通过REST API创建新的构建定义。

我的脚本包含一些文件。在我的脚本中我有这个：

档案1：

 $newDefinitionUrl = "http://tfs:8080/tfs/collection/project/_apis/build/definitions?api-version={2}" -f $CollectionUrl,$TeamProjectName,$BuildApiVersion
        $method = "POST"
        $headers = @{"Content-Type"="application/json"} 
        $body=ConvertTo-Json $template -Depth 20 -Compress  

    #[ERROR 1 - line 80] 
    Invoke-RestMethod -Credential $credentials -Uri $newDefinitionUrl -Method $method -Headers $headers -Body ([System.Text.Encoding]::UTF8.GetBytes($body)) 

文件2：

$templateName = "$bdType $systemTecnology"
$buildDefinitionName = Get-GloboBuildDefinitionName -System $System -BranchName $BranchName -Type $Type

 #[Error 2 - Line 115]
$newDef = New-BuildDefinition -CollectionUrl $Tfs.Uri.AbsoluteUri -TeamProjectName $TeamProjectName -TemplateName $templateName  -BuildDefinitionName $buildDefinitionName -TemplateTeamProjectName $TeamProjectBuildTemplate -OverwriteParameters $parameters 

档案3：

Write-Output "`t-> Criando branch para o $workitemTitle no SourceControl apartir do Release..." -OutVariable +MSGS
        New-TFVCBrach -Tfs $Tfs -SourcePath "$/$TeamProjectName/$System/$branchOrigin" -DestinationPath "$/$TeamProjectName/$System/$branchFolder/$workitemTitle" -ErrorVariable +MSGS | Out-String | Write-Verbose

        Write-Output "`t-> Concedendo permissão ao time ""[$TeamProjectName]\$System"" no branch..." -OutVariable +MSGS
        Get-Content $GloboTFSSetupTemplateFolderPath"\PermissionsFolders.txt" | Set-BranchPermisisons -CollectionUrl $CollectionUrl -TeamProjectName $TeamProjectName -System $System -BranchRelativePath "$branchFolder/$workitemTitle" -Group "[$TeamProjectName]\$System" -ErrorVariable +MSGS | Out-String | Write-Verbose

        Write-Output "`t-> Criando build definition de ""$buildType"" para o ""$WorkItemType""..." -OutVariable +MSGS

#[Error 3 - Line 99]            
New-GloboBuildDefinition -Tfs $Tfs -TeamProjectName $TeamProjectName -System $System -Type $buildType -BranchName $workitemTitle -ErrorVariable +MSGS | Out-String | Write-Verbose 

当我尝试运行脚本时，我得到3个错误，我用＃[Error 1/2/3 - Line x]标记，以便于识别。

这是错误：

在我的TFS 2015中，这个脚本有效。但是现在在2018年的TFS中我得到了这个错误。

谁能帮我这个？

另外我还得到一些错误：

编辑1：我一直试图解决这个问题，我发现了这个：TFS2015 REST API Build definition update

但是我不知道如何解决我的错误。我已经尝试更改我的代码-Depth但我仍然遇到错误。请帮忙。

Answer 1

我从来没有必要使用Text编码来实现此功能。我通常只是将json传递给Invoke-RestMethod请求。我尝试编辑一个已知的好函数来添加编码，它似乎给出了类似的错误。我会尝试将代码调整为：

$newDefinitionUrl = "http://tfs:8080/tfs/collection/project/_apis/build/definitions?api-version={2}" -f $CollectionUrl,$TeamProjectName,$BuildApiVersion
    $method = "POST"
    $headers = @{"Content-Type"="application/json"} 
    $body=ConvertTo-Json $template -Depth 20 -Compress  

#[ERROR 1 - line 80] 
Invoke-RestMethod -Credential $credentials -Uri $newDefinitionUrl -Method $method -Headers $headers -Body $body
