Javascript 是否可以通过编程方式创建报表或将报表链接到Azure数据存储

我想使用PowerBIRESTAPI从我的NodeJS后端将报表连接到azure表存储

让我们举一个基本的例子：

我已经创建了一个报告，并使用Power BI Desktop手动将其连接到Azure表

现在我想复制此报告，但将其源更改为另一个Azure表存储（相同的数据结构，仅值更改）

我认为如何进行：

克隆报告

克隆数据集

更新数据集参数（放置新的Azure表凭据）

将克隆的报告参数更新到新的更新数据集

1。我可以用

对于2：我不知道如何使用powerrestapi复制数据集（我应该创建新的数据集吗？）

对于3：我发现了这一点，但是没有太多关于如何格式化body请求的细节

对于4:

是否可以自动将连接的PBI数据集设置为Azure表存储

还有其他方法吗？

克隆报表API将创建新报表，但它将位于同一数据集上。若要使用自己的数据集生成新报表，必须使用重新发布。您还可以使用下载原始报告。从头开始创建数据集要困难得多——创建所有表、它们的模式、关系、数据源和许多其他细节。你可以用电脑来做。如果这样做，则可以使用将报表重新绑定到新数据集

当数据源为Azure Table时，我不知道body请求的确切模式。下面是一个PowerShell示例，说明如何对SQL Server数据源执行此操作：

Import-Module MicrosoftPowerBIMgmt

# Fill these ###################################################
$workspaceName = "Awesome Reports"
$datasetName = "Awesome Report"
$sqlDatabaseServer = "mycompany.database.windows.net"
$sqlDatabaseName = "CompanyData"
$username = "user@example.com"
$password = "strong password" | ConvertTo-SecureString -asPlainText -Force
################################################################


$credential = New-Object System.Management.Automation.PSCredential($username, $password)
Connect-PowerBIServiceAccount -Credential $credential | Out-Null
$workspace = Get-PowerBIWorkspace -Name $workspaceName
$dataset = Get-PowerBIDataset -WorkspaceId $workspace.Id -Name $datasetName
$datasource = Get-PowerBIDatasource -WorkspaceId $workspace.Id -DatasetId $dataset.Id

# Construct url
$workspaceId = $workspace.Id
$datasetId = $dataset.Id
$datasourceUrl = "groups/$workspaceId/datasets/$datasetId/datasources"

# Call the REST API to get gateway Id, datasource Id and current connection details
$datasourcesResult = Invoke-PowerBIRestMethod -Method Get -Url $datasourceUrl | ConvertFrom-Json

# Parse the response
$datasource = $datasourcesResult.value[0]
$gatewayId = $datasource.gatewayId
$datasourceId = $datasource.datasourceId
$sqlDatabaseServerCurrent = $datasource.connectionDetails.server
$sqlDatabaseNameCurrent = $datasource.connectionDetails.database

# Construct url for update
$datasourePatchUrl = "groups/$workspaceId/datasets/$datasetId/Default.UpdateDatasources"

# create HTTP request body to update datasource connection details
$postBody = @{
  "updateDetails" = @(
   @{
    "connectionDetails" = @{
      "server" = "$sqlDatabaseServer"
      "database" = "$sqlDatabaseName"
    }
    "datasourceSelector" = @{
      "datasourceType" = "Sql"
      "connectionDetails" = @{
        "server" = "$sqlDatabaseServerCurrent"
        "database" = "$sqlDatabaseNameCurrent"
      }
      "gatewayId" = "$gatewayId"
      "datasourceId" = "$datasourceId"
    }
  })
}

$postBodyJson = ConvertTo-Json -InputObject $postBody -Depth 6 -Compress

# Execute POST operation to update datasource connection details
Invoke-PowerBIRestMethod -Method Post -Url $datasourePatchUrl -Body $postBodyJson

您可能可以使用查看原始数据集的外观，并更新上面的示例。但是，您可以使用参数指定数据源，而不是使用此API，这样您就可以使用相同的更新参数API重定向数据源

如果数据源的凭据存储在服务中，您可能需要，例如：

Import-Module MicrosoftPowerBIMgmt

# Fill these ###################################################
$workspaceName = "Awesome Reports"
$datasetName = "Awesome Report"
$sqlDatabaseServer = "mycompany.database.windows.net"
$sqlDatabaseName = "CompanyData"
$username = "user@example.com"
$password = "strong password" | ConvertTo-SecureString -asPlainText -Force
################################################################

$credential = New-Object System.Management.Automation.PSCredential($username, $password)
Connect-PowerBIServiceAccount -Credential $credential | Out-Null
$workspace = Get-PowerBIWorkspace -Name $workspaceName
$dataset = Get-PowerBIDataset -WorkspaceId $workspace.Id -Name $reportName
$workspaceId = $workspace.Id
$datasetId = $dataset.Id
$datasources = Get-PowerBIDatasource -WorkspaceId $workspaceId -DatasetId $datasetId

foreach($datasource in $datasources) {
  $gatewayId = $datasource.gatewayId
  $datasourceId = $datasource.datasourceId
  $datasourePatchUrl = "gateways/$gatewayId/datasources/$datasourceId"
  Write-Host "Patching credentials for $datasourceId"

  # HTTP request body to patch datasource credentials
  $userNameJson = "{""name"":""username"",""value"":""$sqlUserName""}"
  $passwordJson = "{""name"":""password"",""value"":""$sqlUserPassword""}"

  $patchBody = @{
    "credentialDetails" = @{
      "credentials" = "{""credentialData"":[ $userNameJson, $passwordJson ]}"
      "credentialType" = "Basic"
      "encryptedConnection" =  "NotEncrypted"
      "encryptionAlgorithm" = "None"
      "privacyLevel" = "Organizational"
    }
  }

  # Convert body contents to JSON
  $patchBodyJson = ConvertTo-Json -InputObject $patchBody -Depth 6 -Compress

  # Execute PATCH operation to set datasource credentials
  Invoke-PowerBIRestMethod -Method Patch -Url $datasourePatchUrl -Body $patchBodyJson
}

感谢回复，我已经有了一个pbix文件并创建了参数，所以我只需更改参数值，即azure表存储名称。我能用powershell做到吗
