Este artículo forma parte de un tutorial paso a paso para insertar datos en un conjunto de datos.

En el paso 4 de Insertar datos en un conjunto de datos, Obtener un conjunto de datos para agregar filas a una tabla de Power BI, ha utilizado la operación Obtener conjuntos de datos operación y Newtonsoft.Json para obtener un identificador de conjunto de datos. En este paso, el identificador de conjunto de datos se usa con la operación Agregar filas para agregar filas a un conjunto de datos de Power BI. Para ver ejemplos de cómo usar la API de REST de Power BI, consulte API de REST de Power BI en APIARY.

Al llamar a la operación Agregar filas, se agregan filas a un conjunto de datos.

Aquí se muestra cómo agregar filas a un conjunto de datos mediante la API de Power BI.

Agregar filas a una tabla de Power BI

Nota:

Antes de comenzar, asegúrese de que ha seguido los pasos anteriores del tutorial Insertar datos en un conjunto de datos.

  1. En el proyecto de aplicación de consola que creó en Paso 2: Tutorial para insertar datos, Obtener un token de acceso de autenticación, agregue el código siguiente.
  2. Ejecute la aplicación de consola e inicie sesión en su cuenta de Power BI. Debería ver Rows Added en la ventana de consola. También puede iniciar sesión en Power BI para ver las filas agregadas al conjunto de datos.

Ejemplo de inserción de datos en un conjunto de datos

Agregue este código a Program.cs.

  • En static void Main(string[] args):
   static void Main(string[] args)
   {

       //Get an authentication access token
       token = GetToken();

       //Create a dataset in Power BI
       CreateDataset();

       //Get a dataset to add rows into a Power BI table
       string datasetId = GetDataset();

       //Add rows to a Power BI table
       AddRows(datasetId, "Product");
   }     
  • Agregue un método AddRows():
    #region Add rows to a Power BI table
    private static void AddRows(string datasetId, string tableName)
    {
        string powerBIApiAddRowsUrl = String.Format("https://api.powerbi.com/v1.0/myorg/datasets/{0}/tables/{1}/rows", datasetId, tableName);

        //POST web request to add rows.
        //To add rows to a dataset in a group, use the Groups uri: https://api.powerbi.com/v1.0/myorg/groups/{group_id}/datasets/{dataset_id}/tables/{table_name}/rows
        //Change request method to "POST"
        HttpWebRequest request = System.Net.WebRequest.Create(powerBIApiAddRowsUrl) as System.Net.HttpWebRequest;
        request.KeepAlive = true;
        request.Method = "POST";
        request.ContentLength = 0;
        request.ContentType = "application/json";

        //Add token to the request header
        request.Headers.Add("Authorization", String.Format("Bearer {0}", token));

        //JSON content for product row
        string rowsJson = "{\"rows\":" +
            "[{\"ProductID\":1,\"Name\":\"Adjustable Race\",\"Category\":\"Components\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}," +
            "{\"ProductID\":2,\"Name\":\"LL Crankarm\",\"Category\":\"Components\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}," +
            "{\"ProductID\":3,\"Name\":\"HL Mountain Frame - Silver\",\"Category\":\"Bikes\",\"IsCompete\":true,\"ManufacturedOn\":\"07/30/2014\"}]}";

        //POST web request
        byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(rowsJson);
        request.ContentLength = byteArray.Length;

        //Write JSON byte[] into a Stream
        using (Stream writer = request.GetRequestStream())
        {
            writer.Write(byteArray, 0, byteArray.Length);

            var response = (HttpWebResponse)request.GetResponse();

            Console.WriteLine("Rows Added");

            Console.ReadLine();
        }
    }

    #endregion
