我有一个 mvc 应用程序，它有一个主页视图，在主页视图中我有按钮来查看报告，它正在加载两个部分视图，一个是获取 ajax 调用并从表中加载外部 api 数据，另一个部分视图是用于负载 powerbi。

在单击按钮时，我加载了不同的 api 并在 1 个局部视图中获取数据，并在加载 PowerBi 的第二个局部视图时，它重定向到 azure 登录并破坏了应用程序。

public ActionResult Index(){
   var @params = new NameValueCollection
        {
            {"response_type", "code"},
            {"client_id", Properties.Settings.Default.ClientID},
            {"resource", "https://analysis.windows.net/powerbi/api"},
            {"redirect_uri", "http://localhost:13526/Redirect"}
        };


        var queryString = HttpUtility.ParseQueryString(string.Empty);
        queryString.Add(@params);

        string authorityUri = "https://login.windows.net/common/oauth2/authorize/";
        var authUri = String.Format("{0}?{1}", authorityUri, queryString);
        Response.Redirect(authUri);
}

身份验证后，Azure 颁发令牌并加载 powerbi。

嵌入PowerBi

public async Task<ActionResult> EmbedPowerBi ()
{
    AuthenticationResult authResult;
    authResult = (AuthenticationResult)Session["authResult"];
    var token = authResult.AccessToken;
    ViewBag.Token = token;

    var tokenCredentials = new TokenCredentials(token, "Bearer");

    // Create a Power BI Client object. It will be used to call Power BI APIs.
    using (var client = new PowerBIClient(new Uri(ApiUrl), tokenCredentials))
    {
        // Get a list of dashboards.
        var dashboards = await client.Dashboards.GetDashboardsInGroupAsync(GroupId);

        // Get the first report in the group.
        var dashboard = dashboards.Value.FirstOrDefault();
        //var dashboard = dashboards.Value.Where(w => w.Id == "DashboardId");


        // Generate Embed Token.
        var generateTokenRequestParameters = new GenerateTokenRequest(accessLevel: "view");
        var tokenResponse = await client.Dashboards.GenerateTokenInGroupAsync(GroupId, dashboard.Id, generateTokenRequestParameters);

        if (tokenResponse == null)
        {
            return View(new EmbedConfig()
            {
                ErrorMessage = "Failed to generate embed token."
            });
        }

        // Generate Embed Configuration.
        var embedConfig = new EmbedConfig()
        {
            EmbedToken = tokenResponse,
            EmbedUrl = dashboard.EmbedUrl,
            Id = dashboard.Id
        };

        return View(embedConfig);
    }

}

我遇到的问题是由于重定向其他部分视图会影响当前应用程序。

在主视图中，我正在加载部分视图。

@Html.Partial("loadProduct"); @Html.Partial("_EmbedPowerBi");

您是否尝试过参考现有的“开发人员示例”？ https://github.com/Microsoft/PowerBI-Developer-Samples

https://github.com/Microsoft/PowerBI-Developer-Samples/blob/master/App%20Owns%20Data/PowerBIEmbedded_AppOwnsData/Controllers/HomeController.cs#L133

似乎重定向问题导致 ViewModel 绑定到您EmbedConfig
