I'm trying to Embed Power BI Report using .NET Core Web Application and Angular. For this I used PowerBIEmbedded_AppOwnsData( .NET MVC) sample and successfully able to generate tokens and embed the report there
But in .NET Core Application as there is no AcquireTokenAsync method so I refered this Embed Power BI dashboard in ASP.Net core which uses Resource Owner Password Credentials Grant flow and in the below coding using the same request body as I used earlier in PowerBIEmbedded_AppOwnsData(.NET) App.
private async Task<OAuthResult> AuthenticateAsync()
{
var oauthEndpoint = new Uri("https://login.microsoftonline.com/common/oauth2/token");
using (var client = new HttpClient())
{
var result = await client.PostAsync(oauthEndpoint, new FormUrlEncodedContent(new[]
{
new KeyValuePair<string,string>("resource", "https://analysis.windows.net/powerbi/api"),
new KeyValuePair<string,string>("client_id", ApplicationId),
new KeyValuePair<string,string>("client_secret", ApplicationSecret),
new KeyValuePair<string,string>("grant_type", "password"),
new KeyValuePair<string,string>("username", Username),
new KeyValuePair<string,string>("password", Password),
new KeyValuePair<string,string>("scope", "openid")
}
));
var content = await result.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<OAuthResult>(content);
}
}
But this time I am getting an error response which was succesful in .NET Sample
{
"error": "invalid_grant",
"error_description": "AADSTS50126: Invalid username or password.\r\nTrace ID: e4813657-d71a-480c-87a2-1140a49b6f00\r\nCorrelation ID: ba79a622-32e2-4a12-b7fd-65a21a99f378\r\nTimestamp: 2019-05-07 09:46:05Z",
