我已经在react.js应用程序中集成了power-bi服务（应用程序拥有数据/服务原理）。此外，我还想在同一应用程序中集成RLS（行级安全）。如power-bi文档中所述，需要添加嵌入令牌的c#代码，以生成和验证行级安全。
c#代码：

public EmbedToken GetEmbedToken(Guid reportId, IList<Guid> datasetIds, [Optional] Guid targetWorkspaceId)
{
    PowerBIClient pbiClient = this.GetPowerBIClient();

   // Defines the user identity and roles.
    var rlsIdentity = new EffectiveIdentity(
        username: "France",
        roles: new List<string>{ "CountryDynamic" },
        datasets: new List<string>{ datasetId.ToString()}
    );
   
    // Create a request for getting an embed token for the rls identity defined above
    var tokenRequest = new GenerateTokenRequestV2(
        reports: new List<GenerateTokenRequestV2Report>() { new GenerateTokenRequestV2Report(reportId) },
        datasets: datasetIds.Select(datasetId => new GenerateTokenRequestV2Dataset(datasetId.ToString())).ToList(),
        targetWorkspaces: targetWorkspaceId != Guid.Empty ? new List<GenerateTokenRequestV2TargetWorkspace>() { new GenerateTokenRequestV2TargetWorkspace(targetWorkspaceId) } : null,
        identities: new List<EffectiveIdentity> { rlsIdentity }
    );

    // Generate an embed token
    var embedToken = pbiClient.EmbedToken.GenerateToken(tokenRequest);

    return embedToken;
}
