将 power bi 嵌入到 asp net core 2 mvc 中的身份验证

Question

这里有一个很好的例子来说明如何嵌入 powerbi App Owns Data：
https://powerbi.microsoft.com/en-us/documentation/powerbi-developer-embed-sample-app-owns-data/

但是这个例子是在 .net 平台上运行的
并且示例中使用的一些例程对于 aspnetcore 不存在

还有一篇关于有人试图做同样事情的精彩帖子：
Embed Power BI Report In ASP.Net Core Website
还有这个：
https://community.powerbi.com/t5/Developer/Embed-Power-BI-dashboard-in-ASP-Net-core/td-p/273279

但是我什至无法让这些东西进行身份验证
这是我当前的代码的样子：

    private static readonly string AuthorityUrl = "https://login.windows.net/common/oauth2/authorize/";
    private static readonly string ResourceUrl = "https://analysis.windows.net/powerbi/api";
    private static readonly string ApiUrl = "https://api.powerbi.com/";
    private static readonly string EmbedUrl = "https://app.powerbi.com/";
    private static readonly string ClientId = "xxxxclientid";
    private static readonly string Username = "xxxxusername";
    private static readonly string Password = "xxxxpass";
    private static readonly string GroupId = "xxxxgroup";
    private static readonly string ReportId = "xxxxreportid";

    public async Task<ActionResult> embed(string username, string roles)
    {
        var result = new EmbedConfig();
        try
        {
            result = new EmbedConfig { Username = username, Roles = roles };
            var error = GetWebConfigErrors();
            if (error != null)
            {
                result.ErrorMessage = error;
                return View(result);
            }

            var authenticationResult = await AuthenticateAsync();
            if (authenticationResult == null)
            {
                result.ErrorMessage = "Authentication Failed.";
                return View(result);
            }

            var tokenCredentials = new TokenCredentials(authenticationResult.AccessToken, "Bearer");

            ... [the rest is post-authentication stuff, ie powerbi]
}

    private static async Task<OAuthResult> AuthenticateAsync()
    {
        Uri oauthEndpoint = new Uri(AuthorityUrl);
        using (HttpClient client = new HttpClient()) {
            HttpResponseMessage result = await client.PostAsync(oauthEndpoint, new FormUrlEncodedContent(new[]
            {
                new KeyValuePair<string, string>("resource", ResourceUrl),
                new KeyValuePair<string, string>("client_id", ClientId),
                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"),
            }));

            string content = await result.Content.ReadAsStringAsync();
            return JsonConvert.DeserializeObject<OAuthResult>(content);
        }
    }

oAuthResult 类在哪里

   public class OAuthResult
{
    [JsonProperty("token_type")]
    public string TokenType { get; set; }
    [JsonProperty("scope")]
    public string Scope { get; set; }
    [JsonProperty("experies_in")]
    public int ExpiresIn { get; set; }
    [JsonProperty("ext_experies_in")]
    public int ExtExpiresIn { get; set; }
    [JsonProperty("experies_on")]
    public int ExpiresOn { get; set; }
    [JsonProperty("not_before")]
    public int NotBefore { get; set; }
    [JsonProperty("resource")]
    public Uri Resource { get; set; }
    [JsonProperty("access_token")]
    public string AccessToken { get; set; }
    [JsonProperty("refresh_token")]
    public string RefreshToken { get; set; }
}

我知道我的凭据有效
因为我用他们在经典 .net 中构建了原始解决方案
他们工作得很好

但是，现在在这个版本中，我在 AuthenticateAsync 中收到了这个响应（只有一部分）：
"\r\n\r\n\r\n\r\n\r\n 登录您的帐户\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n\r\n \r\n https://login.windows.net/common/jsdisabled\" />\r\n \r\n https ://secure.aadcdn.microsoftonline-p.com/ests/2.1.7382.8/content/images/favicon_a.ico\" />\r\n \r\n "

这显然不是 JSON 响应，而是 ms 登录框的 html
确实我设法渲染了输出，它看起来像这样

谁能给我指出正确的方向，以便 它会正确验证并向我发送令牌而不是登录框？
谢谢你

更新：
我尝试通过浏览器 url 直接登录
这是我使用的网址：
https://login.windows.net/common/oauth2/authorize/?client_id=myid&grant_type=password&username=myun&password=mypw&scope=openid

对于非敏感信息，该网址至少看起来正确吗？
仍然得到登录框

您应该使用：AuthorityUrl = "https://login.windows.net/common/oauth2/token/" 请看-Embed Power BI Report In ASP.Net Core Website
