尝试使用 Power BI REST API 时出错 - Invoke-RestMethod:找不到接受参数的位置参数

Ped*_*uza 0 rest powershell powerbi

最近,我一直在尝试使用Power BI REST API通过调用 .ps1 程序来自动刷新某个数据集。通过遵循教程,我能够获得代码,如下所示:

$groupID = "me" # the ID of the group that hosts the dataset. Use "me" if this is your My Workspace
$datasetID = "MYDATASETID" # the ID of the dataset that hosts the dataset

$clientId = "MYCLIENTID" 

# Calls the Active Directory Authentication Library (ADAL) to authenticate against AAD
function GetAuthToken
{
       if(-not (Get-Module AzureRm.Profile)) {
         Import-Module AzureRm.Profile
       }

       $redirectUri = "urn:ietf:wg:oauth:2.0:oob"

       $resourceAppIdURI = "https://analysis.windows.net/powerbi/api"

       $authority = "https://login.microsoftonline.com/common/oauth2/authorize";

       $authContext = New-Object "Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext" -ArgumentList $authority

       $authResult = $authContext.AcquireToken($resourceAppIdURI, $clientId, $redirectUri, "Auto")

       return $authResult
}

$token = GetAuthToken

$authHeader = @{
   'Content-Type'='application/json'
   'Authorization'=$token.CreateAuthorizationHeader()
}

$groupsPath = ""
if ($groupID -eq "me") {
    $groupsPath = "myorg"
} else {
    $groupsPath = "myorg/groups/$groupID"
}

$uri = "https://api.powerbi.com/v1.0/$groupsPath/datasets/$datasetID/refreshes" 
Invoke-RestMethod -Uri $uri –Headers $authHeader –Method POST –Verbose

$uri = "https://api.powerbi.com/v1.0/$groupsPath/datasets/$datasetID/refreshes"
Invoke-RestMethod -Uri $uri –Headers $authHeader –Method GET –Verbose

我确保完全按照上面链接中的说明收集参数 ( groupID,clientIDdatasetID)。但是,当我尝试执行此代码时,出现错误:

Invoke-RestMethod : A positional parameter cannot be found that accepts argument 'â€Headers System.Collections.Hashtable â€Method'.

我不太清楚发生了什么,我什至发现了一些类似的案例,但没有一个解决方案对我有用。所以,一些帮助将不胜感激。

看起来这个解决方案是从某处复制/粘贴的,并且破折号被搞砸了:

在此处输入图片说明

删除 中的最后 3 个破折号Invoke-RestMethod,它们看起来像破折号,但其他看起来像破折号的 unicode 符号,并将它们替换为正常的“键盘输入”符号。

希望这可以帮助!
