如何在表格模型部署期间传递数据源的凭据？

Question

问题：当我使用部署向导部署表格模型时。它工作正常。但我们的问题是我们有 20 个数据源，在部署时，我们需要提供 20 次凭据，因为它要求为每个数据源提供凭据。这是非常痛苦的。这就是我们要自动化部署的原因。

方法：我按照这篇文章 https://notesfromthelifeboat.com/post/analysis-services-1-deployment/ 进行了操作，我可以毫无错误地部署表格模型，但是当我刷新模型时。它失败并出现以下错误

无法将修改保存到服务器。返回错误：'OLE DB 或 ODBC 错误：

The credentials provided for the File source are invalid. (Source at \share\acaidatatempshare\data\lumeneventpropertiesexport.tsv.).
OLE DB or ODBC error: The command has been canceled..
OLE DB or ODBC error: The command has been canceled..
OLE DB or ODBC error: The command has been canceled..

我的数据源是tsv文件，下面是model.bim文件的数据源部分。如您所见，它不会将凭证的密码保存在 model.bim、asdatabase 或 xmla 文件中。

如何在部署期间以编程方式传递数据源的凭据？

Answer 1

不幸的是，当您部署模型时，结构化（又名 Power Query）数据源凭据不会保留。我前段时间将此作为产品团队的错误报告，但尚未得到回复。如果可以，请考虑改用遗留（又名提供程序）数据源，因为它们会在部署之间保留凭据。

或者，您可以使用 TMSL "createOrReplace" script 以编程方式应用密码。创建脚本等最简单的方法是在 SSMS 中连接到 Analysis Services，右键单击连接（又名数据源），然后选择 "Script Connection as" > "CREATE OR REPLACE To" > "New Query Editor Window"。在生成的脚本中，确保密码设置正确：

{
  "createOrReplace": {
    "object": {
      "database": [...] ,
      "dataSource": "File/\\Share\AcaiDataTempShare\Data\LumenEventPropertiesExport tsv"
    },
    "dataSource": {
    [...]
    "credential": {
      "AuthenticationKind": "Windows",
      "kind": "File",
      "path": "\\Share\acaidatatempshare\data\lumeneventpropertiesexport.tsv",
      "Username": "domain\username",
      "Password": "<<< YOUR PASSWORD HERE >>>"
    },
    [...]
  }

然后您可以调用此脚本作为部署管道的一部分 - 例如使用 PowerShell Invoke-AsCmd cmdlet。
