如何使用Powershell脚本从Azure DevOps获取信息并显示以增强BI服务的功能？

Question

可能有一些方法可以从我的研究中访问RESTful API。 Httpclient？使用ID和密码可能不安全。 使用个人令牌访问Azure Devops的方式是什么？ 任何示例代码？ 下面的代码是我尝试过的，它显示凭据失败。

谢谢。

powershell代码

 function InputToPowerBI {
  param ([string]$type,[string]$title,[string]$assignedTo,[string]$state)
$endpoint =  "address of the end point"
$payload = @{
"Type" =$type
"Title" =$title
"Assigned To" =$assignedTo
"State" =$state
"Area Path" =$areaPath
"Tags" =$tag
"Comment Count" =$commentCount
}

$json = ConvertTo-Json @($payload);

Invoke-RestMethod -Method Post -Uri "$endpoint" -Body $json
}

GetData;



function GetData
{
    try
    {
        $personalAccessToken="Personal token such as eiejr22837482";
        $token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($personalToken)"))
        $header = @{authorization = "Basic $token"}
        $projectsUrl = "address of the current sprint from Azure DevOps"

        $projects = Invoke-RestMethod -Uri $projectsUrl -Method Get -ContentType "application/json" -Headers $header
        $projects.value | ForEach-Object {

}
    }
    catch
    {

    }
