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

Question

这里有一个关于如何嵌入 powerbi App Owns Data 的优秀示例：
https://powerbi.microsoft.com/en-us/documentation/powerbi-developer-embed-sample-app-owns-data/

但是这个例子是针对 .net 平台上的运行
示例中使用的一些例程对于 aspnetcore

不存在

关于有人试图做同样的事情，还有另一个很棒的 post：

还有这个：
https://community.powerbi.com/t5/Developer/Embed-Power-BI-dashboard-in-ASP-Net-core/td-p/273279

但是我什至无法验证这些东西
这是我当前的代码：

    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);
        }
    }

其中 oAuthResult class 是

   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
因为我用它们classic .net 构建了原始解决方案
他们工作得很顺利

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 account\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
事实上，我设法渲染了输出，它看起来像这样

任何人都可以指出我正确的方向以便它正确验证并向我发送令牌而不是登录框？
谢谢

更新:
我试过直接通过浏览器登录url
这是 url 我使用的是：
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，url 至少看起来正确吗？
仍在获取登录框

你应该使用：AuthorityUrl = "https://login.windows.net/common/oauth2/token/" 请参阅 -
