我想使用 Powershell 中的 REST API 向 TFS 项目添加标签。
我正在尝试根据 Visual Studio Integration的文档提出此请求
我这样称呼：
[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.TeamFoundation.Client')
[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.TeamFoundation.WorkItemTracking.Client')
if ( (Get-PSSnapin -Name "Microsoft.TeamFoundation.Powershell" -ErrorAction SilentlyContinue) -eq $null )
{
Add-PSSnapin "Microsoft.TeamFoundation.Powershell"
}
$SrcCollectionUrl = 'http://tfs.myCompany.com:8080/tfs/MyCollection'
$SrcProjectName = 'myProject'
[psobject] $tfs = [Microsoft.TeamFoundation.Client.TeamFoundationServerFactory]::GetServer($SrcCollectionUrl)
[Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStoreFlags]$WorkItemBypass = [Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStoreFlags]::BypassRules
$tfstp = New-Object Microsoft.TeamFoundation.Client.TfsTeamProjectCollection($SrcCollectionUrl)
$WorkItemStore = New-Object -TypeName 'Microsoft.TeamFoundation.WorkItemTracking.Client.WorkItemStore' -ArgumentList $tfs.TfsTeamProjectCollection, $WorkItemBypass
$SrcProject = $WorkItemStore.Projects[$SrcProjectName]
$ProjectGuid = Split-Path $SrcProject.Uri -Leaf
$AddTagsUrl = '{0}/_apis/tagging/scopes/{1}/tags?api-version=1.0' -f $SrcCollectionUrl,$ProjectGuid
$newTagParams = @{name="PWCreateTag2"}
$outjson = $newTagParams | ConvertTo-Json
$nresp = Invoke-RestMethod -Method POST -Uri $AddTagsUrl -UseDefaultCredentials -Body $outjson -ContentType 'application/json'
一切正常。第一次。但是文档指出：“如果该名称的标签已经存在，则不会创建任何标签。相反，响应正文包含具有该名称的现有标签。”
第二次调用我得到的行：“远程服务器返回错误：（400）错误请求。”
有人知道为什么第二次失败了吗？
仅供参考：TFS 服务器是 2015，Powershell 是 V4
