Rest API for Azure SSAS cube refreshment

Question

I'm currently trying to create a Rest API to refresh a SSAS cube in Azure. I followed all the steps from this link . Then I'm using that code to refresh the Cube1 :

#r "Microsoft.AnalysisServices.Tabular.DLL"
#r "Microsoft.AnalysisServices.Core.DLL"
#r "System.Configuration"

using System; 
using System.Security; 
using System.Security.Principal; 
using System.Configuration; 
using Microsoft.AnalysisServices.Tabular;

public static void Run(TimerInfo myTimer, TraceWriter log) 
{
    log.Info($"C# Timer trigger function started at: DateTime.Now}");    
    // try  
    // {
    Microsoft.AnalysisServices.Tabular.Server asSrv = new Microsoft.AnalysisServices.Tabular.Server();

    log.Info("Log1");

    var connStr = "Provider=MSOLAP;Data Source=asazure://serveraddress; Initial Catalog=Cube1;User ID=*****;Password=*****"; 
    log.Info("Log2");

    asSrv.Connect(connStr);        

    log.Info("Log3");   

    Database db = asSrv.Databases["Cube1"]; 
    log.Info("Log4");

    Model m = db.Model; 
    m.RequestRefresh(RefreshType.Full);     // Mark the model for refresh
    db.Model.SaveChanges();     //commit  which will execute the refresh
    asSrv.Disconnect();
    // }
    // catch (Exception e)
    // {
    //     log.Info($"C# Timer trigger function exception: {e.ToString()}");
    // }

    log.Info($"C# Timer trigger function finished at: {DateTime.Now}"); 
}

Normally everything should be ok but here is my error message :

Could not load type 'System.Security.Principal.WindowsImpersonationContext' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=*****

Any idea to solve this ?

Thanks a lot.

好像您缺少对nuget包System.Security.Principal的引用

#r "System.Security.Principal"

Please note that there is REST API available for Azure Analysis Services.

You can find it here https://docs.microsoft.com/en-us/azure/analysis-services/analysis-services-async-refresh

To use it just

1. Create Azure AD Service Principal (Application)
2. Add it as admin to the server
3. Get token for this service principal for resource https://*.asazure.windows.net

4. Send POST request to

   https:// rollout .asazure.windows.net/servers/ serverName /models/ resource /refresh

with body

{
  "Type": "Full",
  "CommitMode": "transactional",
  "MaxParallelism": 2,
  "RetryCount": 2,
  "Objects": [
    {
        "table": "DimCustomer",
        "partition": "DimCustomer"
    },
    {
        "table": "DimDate"
    }
  ]
}
