“指定的值不能转换为ReleaseStartMetadata类型。”触发器VSTS使用powershell发布API时显示的消息

Question

我试图使用powershell调用VSTS发布API，但下面显示了错误消息。当我在postman中运行api时，它工作得很好。

Invoke-RestMethod：{“$Id”：“1”,“innerexception”：null,“message”：“VS402903:指定的值不能转换为ReleaseStartMetadata类型。请确保它可以转换为ReleaseStartMetadata类型，然后再试一次。”,“typeName”：“Microsoft.VisualStudio.Services.ReleaseManagement.data.exceptions.InvalidRequestException,Microsoft.VisualStudio.Services.ReleaseManagement2.data”,“typeKey”：“char:11+$result=Invoke-RestMethod-uri$uri-method post-body$params-hea...stsrelease.ps1:40 char:6+throw“无法定位发行版定义Id$($DefinitionID)”

Powershell代码：

Param(
   [string]$vstsAccount = "demo",
   [string]$projectName = "Enterprise",
   [string]$definitionId = "860",
   [string]$keepForever = "true",
   [string]$personalAccessToken  = "asdfasdf"
)

# Base64-encodes the Personal Access Token (PAT) appropriately
$headers = @{Authorization = 'Basic ' + [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(":$($personalAccessToken)")) }

# Construct the REST URL
$uri = "https://$vstsAccount.vsrm.visualstudio.com/$projectName/_apis/release/releases?api-version=5.0-preview.3"

Write-Host "Uri :" $uri

$params = 
'[
{
    "definitionId": 860,
    "description": "Create Release from postman.",
    "artifacts": [],
    "isDraft": false,
    "reason": "Demo purpose",
    "manualEnvironments": null,
    "environmentsMetadata": null, 
    "properties": null, 
    "variables": null
}
]'

Write-Host " Json Body :" $params

# Invoke the REST call and capture the results
$result = Invoke-RestMethod -Uri $uri -Method POST -Body $params -Headers $headers -ContentType "application/json" -Verbose -Debug

# This call should only provide a single result; Capture the Build ID from the result
if ($result.count -eq 0)
{
     throw "Unable to locate Release Definition Id $($definitionId)"
}
else
{
    Write-host "Success!!!"
}

邮递员要求：

{
    "definitionId": 860,
    "description": "Create Release from postman.",
    "artifacts": [],
    "isDraft": false,
    "reason": "Demo purpose",
    "manualEnvironments": null
}

您将注意到文档中定义的主体与ReleaseStartMetadata相同。尝试指定powershell$params变量中缺少的属性

$params='[{“definitionid”：860,“description”：“from PowerShell.”,“artifacts”：[],“isdraft”：false,“reason”：“demo purpose”,“manualenvironments”：null,“environmentsmetadata”：null,“properties”：null,“variables”：null}]'
