Exportieren des Berichts aus dem PaaS-ArbeitsbereichExport report from PaaS workspace

    // Create a token credentials with "AppKey" type
    var credentials = new TokenCredentials(<myAppKey==>, "AppKey");

    // Instantiate your Power BI client passing in the required credentials
    var client = new PowerBIClient(credentials);

    client.BaseUri = new Uri("https://api.powerbi.com");

    var response = client.Reports.ExportReportWithHttpMessagesAsync(<myWorkspaceCollectionName>, <myWorkspaceId>, <myReportId>);

    if (response.Result.Response.StatusCode == HttpStatusCode.OK)
    {
        var stream = response.Result.Response.Content.ReadAsStreamAsync();

        using (FileStream fileStream = File.Create(@"C:\Migration\myfile.pbix"))
        {
            stream.Result.CopyTo(fileStream);
            fileStream.Close();
        }
    }

Importieren des Berichts in den SaaS-ArbeitsbereichImport report to SaaS workspace

    AuthenticationContext authContext = new AuthenticationContext("https://login.windows.net/common/oauth2/authorize");
    var PBISaaSAuthResult = authContext.AcquireToken("https://analysis.windows.net/powerbi/api", <myClientId>, new Uri("urn:ietf:wg:oauth:2.0:oob"), PromptBehavior.Always);
    var credentials = new TokenCredentials(PBISaaSAuthResult.AccessToken);
    var client = new PowerBIClient(new Uri($"{"https://api.powerbi.com"}"), credentials);
    using (var file = File.Open(@"C:\Migration\myfile.pbix", FileMode.Open))
    {
        client.Imports.PostImportWithFileInGroup(<mySaaSWorkspaceId>, file, "importedreport", "Abort");
        while (true) ;
    }

Extrahieren der DirectQuery-Verbindungszeichenfolge aus dem PaaS-BerichtExtract DirectQuery connection string from PaaS report

Hiermit wird die PBIX-Datei nach der Migration zu SaaS aktualisiert.This is for updating the PBIX after migrating to SaaS.

    // Extract connection string from PaaS - DirectQuery report
    // Create a token credentials with "AppKey" type
    var credentials = new TokenCredentials(<myAppKey==>, "AppKey");

    // Instantiate your Power BI client passing in the required credentials
    var client = new PowerBIClient(credentials);

    client.BaseUri = new Uri("https://api.powerbi.com");

    var reports = client.Reports.GetReports(<myWorkspaceCollectionName>, <myWorkspaceId>);

    Report report = reports.Value.FirstOrDefault(r => string.Equals(r.Id, <myReportId, StringComparison.OrdinalIgnoreCase));

    var datasource = client.Datasets.GetDatasources(<myWorkspaceCollectionName>, <myWorkspaceId>, report.DatasetId);

Aktualisieren der DirectQuery-Verbindungszeichenfolge im SaaS-ArbeitsbereichUpdate DirectQuery connection string is SaaS workspace

    public class ConnectionString
    {
        [JsonProperty(PropertyName = "connectionString")]
        public string connection { get; set; }
    }

    AuthenticationContext authContext = new AuthenticationContext("https://login.windows.net/common/oauth2/authorize");
    var PBISaaSAuthResult = authContext.AcquireToken("https://analysis.windows.net/powerbi/api",<myclient_id>, new Uri("urn:ietf:wg:oauth:2.0:oob"), PromptBehavior.Always);
    var credentials = new TokenCredentials(PBISaaSAuthResult.AccessToken);
    var client = new PowerBIClient(new Uri($"{"https://api.powerbi.com"}"), credentials);

    ConnectionString connection = new ConnectionString() { connection = "data source = <server_name>; initial catalog = <db_name>; persist security info = True; encrypt = True; trustservercertificate = False" };

    client.Datasets.SetAllConnectionsInGroup(<myWorkspaceId>, <dataset_id>, connection);

Festlegen von DirectQuery-Anmeldeinformationen im SaaS-ArbeitsbereichSet DirectQuery credentials in SaaS workspace

In diesem Codeausschnitt werden zur Vereinfachung unverschlüsselte Anmeldeinformationen verwendet. Senden von verschlüsselten Anmeldeinformationen wird aber ebenfalls unterstützt.In this snippet, we are using unencrypted credentials for simplicity, sending encrypted credentials is supported as well.

    public class ConnectionString
    {
        [JsonProperty(PropertyName = "connectionString")]
        public string connection { get; set; }
    }

    public class BasicCreds
    {
        [JsonProperty(PropertyName = "username")]
        public string user { get; set; }

        [JsonProperty(PropertyName = "password")]
        public string pwd { get; set; }
    }

    var basicCreds = new BasicCreds() { user = <sqldb_username>, pwd = <sqldb_password> };
    var body = new SetCredsRequestBody() { credentialType = "Basic", basicCreds = basicCreds };

    var url = string.Format("https://api.powerbi.com/v1.0/myorg/gateways/{0}/datasources/{1}", <gateway_id>, <datasource_id>);
    var request = new HttpRequestMessage(new HttpMethod("PATCH"), url);
    // Set authorization header from you acquired Azure AD token
    AuthenticationContext authContext = new AuthenticationContext("https://login.windows.net/common/oauth2/authorize");
    var PBISaaSAuthResult = authContext.AcquireToken("https://analysis.windows.net/powerbi/api", <myclient_id>, new Uri("urn:ietf:wg:oauth:2.0:oob"), PromptBehavior.Always);

    request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", PBISaaSAuthResult.AccessToken);

    request.Content = new StringContent(JsonConvert.SerializeObject(body), Encoding.UTF8, "application/json");

    HttpClient simpleClient = new HttpClient();
    var response = await simpleClient.SendAsync(request);

Übertragen von Dataset und Bericht per PushPush dataset & report

Sie müssen den Bericht für das erstellte Dataset neu erstellen.You will need to rebuild the report for the created dataset.

Für diesen Codeausschnitt wird angenommen, dass sich das im Pushverfahren übertragbare Dataset bereits in einem App-Arbeitsbereich in der SaaS-Umgebung befindet.In this snippet, we assume that the pushable dataset is already in an app workspace within the SaaS environment. Informationen über die Push-API finden Sie unter Übertragen von Daten in ein Power BI-Dataset per Push.For information about the push API, see Push data into a Power BI dataset.

    var credentials = new TokenCredentials(<Your WSC access key>, "AppKey");

    // Instantiate your Power BI client passing in the required credentials
    var client = new Microsoft.PowerBI.Api.V1.PowerBIClient(credentials);
    client.BaseUri = new Uri("https://api.powerbi.com");

    // step 1 -> create dummy dataset at PaaS worksapce
    var fileStream = File.OpenRead(<Path to your dummy dataset>);
    var import = client.Imports.PostImportWithFileAsync(<Your WSC NAME>, <Your workspace ID>, fileStream, "dummyDataset");
    while (import.Result.ImportState != "Succeeded" && import.Result.ImportState != "Failed")
    {
        import = client.Imports.GetImportByIdAsync(<Your WSC NAME>, <Your workspace ID>, import.Result.Id);
        Thread.Sleep(1000);
    }
    var dummyDatasetID = import.Result.Datasets[0].Id;

    // step 2 -> clone the pushable dataset and rebind to dummy dataset
    var cloneInfo = new Microsoft.PowerBI.Api.V1.Models.CloneReportRequest("pushableReportClone",null, dummyDatasetID);
    var clone = client.Reports.CloneReportAsync(<Your WSC NAME>, <Your workspace ID>, <Your pushable report ID>, cloneInfo);
    var pushableReportCloneID = clone.Result.Id;


    // step 3 -> Download the push API clone report with the dummy dataset
    var response = client.Reports.ExportReportWithHttpMessagesAsync(<Your WSC NAME>, <Your workspace ID>, pushableReportCloneID);
    if (response.Result.Response.StatusCode == HttpStatusCode.OK)
    {
        var stream = response.Result.Response.Content.ReadAsStreamAsync();
        using (fileStream = File.Create(@"C:\Migration\PushAPIReport.pbix"))
        {
            stream.Result.CopyTo(fileStream);
            fileStream.Close();
        }
    }

    // step 4 -> Upload dummy PBIX to SaaS workspace
    AuthenticationContext authContext = new AuthenticationContext("https://login.windows.net/common/oauth2/authorize");
    var PBISaaSAuthResult = authContext.AcquireToken("https://analysis.windows.net/powerbi/api", <Your client ID>, new Uri("urn:ietf:wg:oauth:2.0:oob"), PromptBehavior.Always);
    var credentialsSaaS = new TokenCredentials(PBISaaSAuthResult.AccessToken);
    var clientSaaS = new Microsoft.PowerBI.Api.V2.PowerBIClient(new Uri($"{"https://api.powerbi.com"}"), credentialsSaaS);
    using (var file = File.Open(@"C:\Migration\PushAPIReport.pbix", FileMode.Open))
    {

        var importSaaS = clientSaaS.Imports.PostImportWithFileAsyncInGroup(<Your GroupID>, file, "importedreport1", "Abort");
        while (importSaaS.Result.ImportState != "Succeeded" && importSaaS.Result.ImportState != "Failed")
        {
            importSaaS = clientSaaS.Imports.GetImportByIdAsync(importSaaS.Result.Id);
            Thread.Sleep(1000);
        }
        var importedreport1ID = importSaaS.Result.Reports[0].Id;


        // step 5 -> Rebind report to "real" push api dataset
        var rebindInfoSaaS = new Microsoft.PowerBI.Api.V2.Models.RebindReportRequest(<Your pushable dataset  ID at power bi>);
        var rebindSaaS = clientSaaS.Reports.RebindReportInGroupWithHttpMessagesAsync(<Your GroupID>, importedreport1ID, rebindInfoSaaS);

    }
