我正在尝试使用PowerShell脚本的POST方法刷新power bi数据集,但是不断收到有关媒体类型的错误,所以不知道该怎么做。只是好奇其他人是否有任何解决方案。在此先感谢您的帮助!!

# This sample script calls the Power BI API to progammtically trigger a refresh for the dataset
# It then calls the Power BI API to progammatically to get the refresh history for that dataset
# For full documentation on the REST APIs, see:
# https://msdn.microsoft.com/en-us/library/mt203551.aspx
# Instructions:
# 1. Install PowerShell (https://msdn.microsoft.com/en-us/powershell/scripting/setup/installing-windows-powershell) and the Azure PowerShell cmdlets (https://aka.ms/webpi-azps)
# 2. Set up a dataset for refresh in the Power BI service - make sure that the dataset can be
# updated successfully
# 3. Fill in the parameters below
# 4. Run the PowerShell script
# Parameters - fill these in before running the script!
# =====================================================
# An easy way to get group and dataset ID is to go to dataset settings and click on the dataset
# that you'd like to refresh. Once you do, the URL in the address bar will show the group ID and
# dataset ID, in the format:
# app.powerbi.com/groups/{groupID}/settings/datasets/{datasetID}
$groupID = " FILL ME IN " # the ID of the group that hosts the dataset. Use "me" if this is your My Workspace
$datasetID = " FILL ME IN " # the ID of the dataset that hosts the dataset
# AAD Client ID
# To get this, go to the following page and follow the steps to provision an app
# https://dev.powerbi.com/apps
# To get the sample to work, ensure that you have the following fields:
# App Type: Native app
# Redirect URL: urn:ietf:wg:oauth:2.0:oob
# Level of access: all dataset APIs
$clientId = " FILL ME IN "
# End Parameters =======================================
# Calls the Active Directory Authentication Library (ADAL) to authenticate against AAD
function GetAuthToken

$authContext = New-Object "Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext" -ArgumentList $authority
$authResult = $authContext.AcquireToken($resourceAppIdURI, $clientId, $redirectUri, "Auto")
return $authResult
}
# Get the auth token from AAD
$token = GetAuthToken
# Building Rest API header with authorization token
$authHeader = @{
'Content-Type'='application/json'
'Authorization'=$token.CreateAuthorizationHeader()
}
# properly format groups path
$groupsPath = ""
if ($groupID -eq "me") {
$groupsPath = "myorg"
} else {
$groupsPath = "myorg/groups/$groupID"
}
# Refresh the dataset
$uri = "https://api.powerbi.com/v1.0/$groupsPath/datasets/$datasetID/refreshes"
Invoke-RestMethod -Uri $uri -Headers $authHeader -Method POST -Verbose
# Check the refresh history
$uri = "https://api.powerbi.com/v1.0/$groupsPath/datasets/$datasetID/refreshes"
Invoke-RestMethod -Uri $uri -Headers $authHeader -Method GET -Verbose

我遇到过这个问题。
您基本上是尝试从无法刷新的数据集返回刷新信息(例如,直接查询数据集或内置度量数据集)
您需要添加-ErrorAction SilentlyContinue
或将数据集刷新API调用包装在这样的循环中:
$ datasets = Invoke-RestMethod -Uri $ uri -Headers $ authHeader -Method GET
foreach($dataset in $datasets.value)
{
if($dataset.isRefreshable -eq $true)
{
#Build API String
$uri2 = "https://api.powerbi.com/v1.0/$groupsPath/datasets/$($dataset.id)/refreshes"
#Return refresh info for each dataset
$refreshes = Invoke-RestMethod -Uri $uri2 -Headers $authHeader -Method GET
}
}
