Error on Report Viewer with Power BI Report Server

floshdraw — Tue, 09 Oct 2018 17:02:08 GMT

Hello all,

I'm testing some ways to embed Power BI reports which store on Power BI Report Server and I am developping a web page in asp.net to view a report.

I have successfully connected to my reports I believe but I have a message "Request failed with empty response" when I get report.

All is ok when I connect directly on browser on portal.

Do you have some ideas about this one ?

Find asp class

using Microsoft.Reporting.WebForms;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Net;
using System.Security.Principal;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace ReportViewer_PowerBI
{
    public partial class WebForm1 : System.Web.UI.Page
    {

        private String username;
        private String pwd;
        private String report;

        protected void Page_Load(object sender, EventArgs e)
        {
            ReportViewer1.ProcessingMode = ProcessingMode.Remote;
        }


        protected void Button1_Click(object sender, EventArgs e)
        {
            username = this.txtUser.Text;
            pwd = this.txtPassword.Text;
            report = this.txtReport.Text;

            ReportViewer1.Reset();
            ReportViewer1.ServerReport.ReportServerCredentials = new CustomReportCredentials(username, pwd, "XX");
            ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://myReport");
            ReportViewer1.ServerReport.ReportPath = "/" + report;

            //ReportViewer1.ServerReport.Refresh();

        }
    }

    /// 
    /// Summary description for CustomReportCredentials
    /// 
    public class CustomReportCredentials :
    Microsoft.Reporting.WebForms.IReportServerCredentials
    {

        // local variable for network credential.
        private string _UserName;
        private string _PassWord;
        private string _DomainName;
        public CustomReportCredentials(string UserName, string PassWord,
    string DomainName)
        {
            _UserName = UserName;
            _PassWord = PassWord;
            _DomainName = DomainName;
        }
        public WindowsIdentity ImpersonationUser
        {
            get
            {
                return null;  // not use ImpersonationUser
            }
        }
        public ICredentials NetworkCredentials
        {
            get
            {

                // use NetworkCredentials
                return new NetworkCredential(_UserName,
    _PassWord, _DomainName);
            }
        }
        public bool GetFormsCredentials(out Cookie authCookie,
    out string user, out string password, out string authority)
        {

            // not use FormsCredentials unless you have 
            //implements a custom autentication.
        authCookie = null;
            user = password = authority = null;
            return false;
        }
    }
}

And also form web

<body>
    <form id="form1" runat="server">
        
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <rsweb:ReportViewer ID="ReportViewer1" runat="server" ProcessingMode="Remote" Height="297px">
                <ServerReport />
        </rsweb:ReportViewer>
        
        <p>
            User<asp:TextBox ID="txtUser" runat="server"></asp:TextBox>
        </p>
        <p id="txtPwd">
            Password<asp:TextBox ID="txtPassword" runat="server" style="margin-bottom: 0px"></asp:TextBox>
        </p>
        <p>
            Report<asp:TextBox ID="txtReport" runat="server" style="margin-bottom: 4px"></asp:TextBox>
        </p>
        <p>
            <asp:Button ID="btnVal" runat="server" OnClick="Button1_Click" Text="Load" />
        </p>
