Extraits de code pour migrer du contenu à partir de Power BI EmbeddedCode snippets for migrating content from Power BI Embedded

Voici quelques extraits de code pour les opérations de base nécessaires à la migration de contenu.Here are some code snippets of basic operations needed for content migration. Pour les flux liés à certains types de rapports, consultez la page Comment migrer le contenu d’une collection d’espaces de travail Power BI Embedded vers Power BI.For related flows for certain report types, see How to migrate Power BI Embedded workspace collection content to Power BI.

Un outil de migration est à votre disposition pour vous aider à copier le contenu de Power BI Embedded (PaaS) vers le service Power BI (SaaS).A migration tool is available for you to use in order to assist with copying content from Power BI Embedded (PaaS) to the Power BI service (SaaS). Celui-ci est particulièrement utile si votre contenu est volumineux.Especially if you have a lot of content. Pour plus d’informations, consultez Outil de migration Power BI Embedded.For more information, see Power BI Embedded migration tool.

Extraire la chaîne de connexion DirectQuery du rapport PaaSExtract DirectQuery connection string from PaaS report

Ceci sert à mettre à jour le PBIX après la migration vers SaaS.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 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);

Définir les informations d’identification de DirectQuery dans l’espace de travail SaaSSet DirectQuery credentials in SaaS workspace

Dans cet extrait de code, nous utilisons des informations d’identification non chiffrées par souci de simplicité. Il est possible d’envoyer des informations d’identification chiffrées.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);

Jeu de données et rapport de transmissionPush dataset & report

Vous devez régénérer le rapport pour le jeu de données créé.You will need to rebuild the report for the created dataset.

Dans cet extrait de code, nous supposons que le jeu de données utilisant le service push est déjà dans un espace de travail d’application dans l’environnement SaaS.In this snippet, we assume that the pushable dataset is already in an app workspace within the SaaS environment. Pour plus d’informations sur l’API push, consultez Transmission de données à un jeu de données Power BI.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);
