從PS腳本增加DevOps變陣列值時出現錯誤TF400898

我在使用 Powershell 腳本來獲取、遞增并將新值放入 DevOps 變陣列中的變數時遇到問題。

在 $json 物件字串中添加變數似乎存在問題。不知道如何將增量值添加到字串中，請指教！

劇本：

# Base64-encodes the Personal Access Token (PAT) appropriately
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f "","$env:SYSTEM_ACCESSTOKEN")))
$url = "$($env:SYSTEM_TEAMFOUNDATIONCOLLECTIONURI)$env:SYSTEM_TEAMPROJECTID/_apis/distributedtask/variablegroups/1?api-version=6.0-preview.1"

$pipeline = Invoke-RestMethod -Uri $url -Method Get -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
Write-Host "Get Variable Value:" $pipeline.variables.MinorVersion.value

$versionNumber = [int]$pipeline.variables.MinorVersion.value
$versionNumber  
Write-Host "$versionNumber Variable Value:" $versionNumber

$json = '{"id":2555,"type":"Vsts","name":"VersionNumberVG","variables":{"MinorVersion":{"value":$versionNumber}}}'
$pipeline = Invoke-RestMethod -Uri $url -Method Put -Body $json -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
Write-Host "PUT New Variable Value:" $pipeline.variables.MinorVersion.value

$pipeline = Invoke-RestMethod -Uri $url -Method Get -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
Write-Host "Get Variable Value:" $pipeline.variables.MinorVersion.value

我得到的錯誤：

uj5u.com熱心網友回復：

問題的原因是正文格式有問題。

您可以嘗試以下 PowerShell 示例來定義主體并運行 Rest API：

$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f "","$env:SYSTEM_ACCESSTOKEN")))
$url = "$($env:SYSTEM_TEAMFOUNDATIONCOLLECTIONURI)$env:SYSTEM_TEAMPROJECTID/_apis/distributedtask/variablegroups/1?api-version=6.0-preview.1"

$pipeline = Invoke-RestMethod -Uri $url -Method Get -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
Write-Host "Get Variable Value:" $pipeline.variables.MinorVersion.value

$versionNumber = [int]$pipeline.variables.MinorVersion.value
$versionNumber  
Write-Host "$versionNumber Variable Value:" $versionNumber


$json = 
"{
    `"name`":`"VersionNumberVG`",

    `"type`":`"Vsts`",
    `"variables`":{
        `"MinorVersion`":{
            `"isSecret`":false,
            `"value`": `"$versionNumber`"
            }
        }

}"
$pipeline = Invoke-RestMethod -Uri $url -Method Put -Body $json -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
Write-Host "PUT New Variable Value:" $pipeline.variables.MinorVersion.value

$pipeline = Invoke-RestMethod -Uri $url -Method Get -ContentType "application/json" -Headers @{Authorization=("Basic {0}" -f $base64AuthInfo)}
Write-Host "Get Variable Value:" $pipeline.variables.MinorVersion.value

結果：
