“Hyak.Common.Cloudexception Authentication Failed” 尝试连接到 azure 并加载订阅时

如果在尝试使用我的代码登录 Azure 并对 Azure 进行身份验证时遇到 cloudexception以下 ASP.NET 错误

代码出错的地方

private void LoadSubscriptions()
{
    if (Session["AzureAuthentication"] == null)
        return;

    var mainAuthRes = 
(Task<AuthenticationResult>)Session["AzureAuthentication"];

    var subscriptionCredentials = new TokenCloudCredentials(mainAuthRes.Result.AccessToken);

    var cancelToken = new CancellationToken();
    using (var subscriptionClient = new SubscriptionClient(subscriptionCredentials))
    {
        var tenants = subscriptionClient.Tenants.ListAsync(cancelToken).Result;
        foreach (var tenantDescription in tenants.TenantIds)

我不知道为什么它会在以下位置出现错误：
var tenants = subscriptionClient.Tenants.ListAsync(cancelToken).Result;

mainAuthRes.Result.AccessToken 实际上在 Debug 中显示了一个 Accesstoken

我的授权码

将身份验证作为会话发送到 LoadSubscriptions 类

public void GetAuthorizationCode()
{
    JObject response = new JObject();

    var parameters = new Dictionary<string, string>
        {
            { "response_type", "code" },
            { "client_id", clientId },
            { "redirect_uri", url },
            { "prompt", "login"},
            { "scope", "openid"}
        };

    var requestUrl = string.Format("{0}/authorize?{1}", EndPointUrl,BuildQueryString(parameters));

    Response.Redirect(requestUrl);

}

public string AcquireTokenWithResource(string resource)
{
    var code = Request.Params["code"];
    AuthenticationContext ac = new AuthenticationContext(string.Format("https://login.microsoftonline.com/{0}", directoryId));
    ClientCredential clcred = new ClientCredential(clientId, clientSecret);
        var result = ac.AcquireTokenByAuthorizationCodeAsync(code, new Uri(url), clcred, resource);

    Session["AzureAuthentication"] = result;

    return result.Result.AccessToken;
}

private string BuildQueryString(IDictionary<string, string> parameters)
{
    var list = new List<string>();

    foreach (var parameter in parameters)
    {
        list.Add(string.Format("{0}={1}", parameter.Key, HttpUtility.UrlEncode(parameter.Value)));
    }

    return string.Join("&", list);
}

protected string EndPointUrl
{
    get
    {
        return string.Format("{0}/{1}/{2}", "https://login.microsoftonline.com", directoryId, @"oauth2/");
    }
}

谁能看出哪里出错了。
