您不能将Invoke Rest API门与Azure DevOps API URL一起使用，因为要检查上次发布状态，您需要检查环境（阶段）状态，为此，您需要发布ID（因此，无法知道它将是什么并将其放入其余的API门URL中。）

但是，您可以使用PowerShell来检查最新版本，如果未成功发布，请通过该阶段。

在您的发行版中添加PowerShell任务以检查上一个发行版：

$headers = @{ Authorization = "Bearer $env:SYSTEM_ACCESSTOKEN"  }

# Replace {org} with your organization
# Replace {project} with your project
# Replace {defId} with your release definition id

$url = "https://vsrm.dev.azure.com/{org}/{project}/_apis/release/releases?definitionId={defId}&api-version=5.1"
$releases = Invoke-RestMethod -Method Get -Uri $url -Headers $headers -ContentType 'application/json'

$releaseUrl = "https://vsrm.dev.azure.com/{org}/{project}/_apis/release/releases/$($releases.value[1].id)?api-version=5.1"
$releaseInfo = Invoke-RestMethod -Method Get -Uri $releaseUrl -Headers $headers -ContentType 'application/json'

$releaseEvnriomentId =  $releaseInfo.environments.Where({ $_.name -eq 'THE STAGE NAME WHERE YOU DO MERGE' }).id

$envUrl = "https://vsrm.dev.azure.com/{org}/{project}/_apis/Release/releases/$($releases.value[1].id)/environments/$($releaseEvnriomentId)?api-version=5.1-preview.1"
$environment = Invoke-RestMethod -Method Get -Uri $envUrl -Headers $headers -ContentType 'application/json'

$envStatus = $environment.status

if($envStatus -ne "succeeded")
{
    Write-Error "Previous release not succeeded!"
}
else
{
    Write-Host "Previous release succeeded :)" 
}

在代理作业选项中，您需要允许脚本访问OAuth令牌：

Azure函数还支持PowerShell，因此您也可以使用Azure函数gate：

1）使用VS代码创建新的Azure函数，如说明的here。

2）在您的run.ps1文件中，将代码替换为以下代码：

using namespace System.Net

# Input bindings are passed in via param block.
param($Request,$TriggerMetadata)

# Write to the Azure Functions log stream.
Write-Host "PowerShell HTTP trigger function processed a request."

$defnitionId = $Request.Query.DefinitionId

# Generate PAT and put it in the {YOUR PAT}
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,"{YOUR PAT}")))
$headers = @{Authorization=("Basic {0}" -f $base64AuthInfo)}

# Replace {org} with your organization
# Replace {project} with your project

$url = "https://vsrm.dev.azure.com/{org}/{project}/_apis/release/releases?definitionId=$($defnitionId)&api-version=5.1"
$releases = Invoke-RestMethod -Method Get -Uri $url -Headers $headers -ContentType 'application/json'
Write-Debug $releases

$releaseUrl = "https://vsrm.dev.azure.com/{org}/{project}/_apis/release/releases/$($releases.value[1].id)?api-version=5.1"
$releaseInfo = Invoke-RestMethod -Method Get -Uri $releaseUrl -Headers $headers -ContentType 'application/json'
Write-Debug $releaseInfo

$releaseEvnriomentId =  $releaseInfo.environments.Where({ $_.name -eq 'THE STAGE NAME WHERE YOU DO MERGE' }).id

$envUrl = "https://vsrm.dev.azure.com/{org}/{project}/_apis/Release/releases/$($releases.value[1].id)/environments/$($releaseEvnriomentId)?api-version=5.1-preview.1"
$environment = Invoke-RestMethod -Method Get -Uri $envUrl -Headers $headers -ContentType 'application/json'
Write-Debug $environment

$envStatus = $environment.status
Write-Debug $envStatus

if($envStatus -ne "succeeded")
{
    $status = [HttpStatusCode]::BadRequest
    $body = "failed"
}
else
{
    $status = [HttpStatusCode]::OK
    $body = "success"
}


# Associate values to output bindings by calling 'Push-OutputBinding'.
Push-OutputBinding -Name Response -Value ([HttpResponseContext]@{
    StatusCode = $status
    Body = $body
})

3）将功能发布到Azure。

4）在您的版本中创建一个“调用Azure功能”门：

另一种方法是，使用上面的代码，将他转换为C＃或使用Rest API的另一种语言，然后将其部署到Web服务器并使用Invoke Rest API Gate。
