通过 REST API 的 VSTS 工作项列表

Question

如何使用 REST API 从 VSTS 获取工作项列表？

根据文档，该ids参数是可选的，但是当我省略它时，我会收到404错误消息。如果我添加ids参数，我可以获得项目。

失败的请求：
GET https://{account}.visualstudio.com/DefaultCollection/_apis/wit/workitems?api-version=1.0

成功请求：
GET https://{account}.visualstudio.com/DefaultCollection/_apis/wit/workitems?ids=252&api-version=1.0

两者的身份验证相同。

要解决的完整问题是：获取特定 VSTS 项目中的所有功能

关键是使用API 的WIQL部分，而不是工作项。例如，要获取某种类型的工作项的平面列表，请使用：https : //www.visualstudio.com/en-us/docs/integrate/api/wit/wiql#a-flat-query

PowerShell 中的示例（显示处于关闭状态的所有用户故事）：

    # using env vars passed from VSTS build
    $collectionuri = $Env:SYSTEM_TEAMFOUNDATIONCOLLECTIONURI
    $token = $Env:SYSTEM_ACCESSTOKEN # need to configure build to allow passing OAuth tokens

    $basicAuth = "{0}:{1}"-f "ivan-the-terrible", $token
    $basicAuth = [System.Text.Encoding]::UTF8.GetBytes($basicAuth)
    $basicAuth = [System.Convert]::ToBase64String($basicAuth)
    $headers = @{Authorization=("Basic {0}"-f $basicAuth)}

    $WorkItemType = 'User Story'

    $url = $collectionuri + 'DefaultCollection/_apis/wit/wiql?api-version=1.0'

    $WIQL_query = "Select [System.Id], [System.Title], [System.State] From WorkItems Where [System.WorkItemType] = '" + $WorkItemType + "' AND [State] = 'Closed' order by [Microsoft.VSTS.Common.Priority] asc, [System.CreatedDate] desc"
    $body = @{ query = $WIQL_query }
    $bodyJson=@($body) | ConvertTo-Json

    $response = Invoke-RestMethod -Uri $url -headers $headers -Method Post -ContentType "application/json" -Body $bodyJson

    $workitems = $response.workItems

    Write-Host "Found" $workitems.Count "work items of type:" $WorkItemType
