PowerBI API | Import PBIX

Hello,

 

I have a method to upload a .PBIX file to my PowerBI App, This method return a id as expected. However the reports and datasets doesn't appear on PowerBI

 

My Method :

 

   public static string SendFile()
        {

            string[] files = { "D://David/Documents//PBIX_TEST.pbix" };


            string boundary = "----------------------------" + DateTime.Now.Ticks.ToString("x");
            HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.powerbi.com/beta/myorg/imports?datasetDisplayName=PBI_TESTT");
            httpWebRequest.ContentType = "multipart/form-data; boundary=" + boundary;
            httpWebRequest.Method = "POST";
            httpWebRequest.KeepAlive = true;
            //httpWebRequest./*Credentials*/ = System.Net.CredentialCache.DefaultCredentials;
            httpWebRequest.Headers.Add("Authorization", String.Format("Bearer {0}", nsToken.TokenSingleton.Instance.token.AccessToken));
            Stream memStream = new System.IO.MemoryStream();
            byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n");
            string formdataTemplate = "\r\n--" + boundary + "\r\nContent-Disposition:  form-data; name=\"{0}\";\r\n\r\n{1}";
            string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n Content-Type: application/octet-stream\r\n\r\n";
            memStream.Write(boundarybytes, 0, boundarybytes.Length);
            for (int i = 0; i < files.Length; i++)
            {
                string header = string.Format(headerTemplate, "fieldNameHere", "PBIX_TEST.pbix");
                //string header = string.Format(headerTemplate, "uplTheFile", files[i]);
                byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
                memStream.Write(headerbytes, 0, headerbytes.Length);
                FileStream fileStream = new FileStream(files[i], FileMode.Open,
                FileAccess.Read);
                byte[] buffer = new byte[1024];
                int bytesRead = 0;
                while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
                {
                    memStream.Write(buffer, 0, bytesRead);
                }
                memStream.Write(boundarybytes, 0, boundarybytes.Length);
                fileStream.Close();
            }
            httpWebRequest.ContentLength = memStream.Length;
            Stream requestStream = httpWebRequest.GetRequestStream();
            memStream.Position = 0;
            byte[] tempBuffer = new byte[memStream.Length];
            memStream.Read(tempBuffer, 0, tempBuffer.Length);
            memStream.Close();
            requestStream.Write(tempBuffer, 0, tempBuffer.Length);
            requestStream.Close();
            try
            {
                WebResponse webResponse = httpWebRequest.GetResponse();
                Stream stream = webResponse.GetResponseStream();
                StreamReader reader = new StreamReader(stream);
                string var = reader.ReadToEnd();

                var jsonSerializer = new JavaScriptSerializer();
                var dataset = (dataset)jsonSerializer.Deserialize(var, typeof(dataset));
                return dataset.Id;

            }
            catch (Exception ex)
            {
                throw ex;
            }
            httpWebRequest = null;
        }

 

Can anyone help me ? 

 

Thanks

The call happens async. When you do a call to GET .../imports/{importID} do you see any error message in the status?
