Question

是否可以以某种方式备份/导出/下载所有工作项？我看了一下REST API，但似乎你无法执行f.e.通过此API查询...

Answer 1

好的，找到了完成工作的方法。我再看一下API文档。页面https://www.visualstudio.com/en-us/docs/integrate/api/wit/overview帮助了我。你首先需要做一个

GET https://{account}.visualstudio.com/defaultcollection/{project}/_apis/wit/queries/{folderpath}?api-version={version}&$expand=wiql

从生成的JSON中，您需要获取wiql部分，这是实际的查询。在此之后你需要做一个

POST https://{account}.visualstudio.com/defaultcollection/{project}/_apis/wit/wiql?api-version={version}

身体是JSON，{{＃34;查询＆＃34; =＆＃34; YOURQUERY＆＃34; }

因此，您将收到一个包含所有工作项网址/ ID的JSON。您需要通过它们并通过

查询每个工作项

GET URL?$expand=all

注意：只有在需要关系和附件时才添加？$ expand = all。我把一些东西放在一起用于PowerShell。注意：我决定对查询进行硬编码并删除错误处理以使其缩短。

function loadJsonFile($fileName) 
{
    return ConvertFrom-Json "$(Get-Content $fileName)"
}
function getLastItemFromURL($url) 
{
    $absPath = ([System.Uri]$url).AbsolutePath
    $lastSlash = $absPath.LastIndexOf("/")
    $absPath.Substring($lastSlash+1)
}
function getWorkItemId($url)
{
    getLastItemFromURL($url)
}

# make sure you enabled alternative credentials and access for them
# you can get the value for YOURCODE i.e. via Fiddler
$headers = @{Authorization="Basic YOURCODE"}

# before this you would need to find the WIQL of the query; left to you
$body = @{  
    "query" = "THEQUERYFROMTHEJSON"
}
$bodyJson = $body | ConvertTo-Json

Invoke-RestMethod -method Post -ContentType application/json -Uri "https://{account}.visualstudio.com/defaultcollection/{project}/_apis/wit/wiql?api-version=1.0" -Headers $headers -Body $bodyJson -OutFile workitems.json

$workItemsJson = $(loadJsonFile workitems.json)
$workItems = $(foreach ($relation in $workItemsJson.workItemRelations)
{
    $relation.target.url
    $relation.source.url
}) | select -Unique | sort

echo "Going to download the following ids from $(getWorkItemId $workItems[0])-$(getWorkItemId $workItems[-1])"

# download the workitems
foreach($workItemUrl in $workItems)
{
    $workItemId = getWorkItemId $workItemUrl
    echo "Download ID: $workItemId"

    $workItemUrl = "$workItemUrl`?`$expand=all"
    $fileName = "workitem_$workItemId.json"
    Invoke-RestMethod -ContentType application/json -Uri "$workItemUrl" -Headers $headers -OutFile "$fileName"

    # download attachments
    $workItemJson = $(loadJsonFile "$fileName")
    foreach($relation in $workItemJson.relations)
    {
        if($relation.rel -eq "AttachedFile") 
        {
            $fileUrl = $relation.url
            Invoke-WebRequest $fileUrl -Headers $headers -OutFile $(getLastItemFromURL $fileUrl)
        }
    }
}

您可以使用Team Foundation加载项将工作项查询导出到Excel，如所述here

VS Team Services上的备份工作项
