来自 Web 应用程序的 Azure 异步身份验证令牌

我正在尝试从 Azure AD 系统检索身份验证令牌。我尝试了多种不同的方式来配置异步方法和 await 命令，但每次我都收到错误“任务被取消”。

我的 aspx 页面中有 async="true" 。

为了获得成功的请求并检索令牌，我需要做什么不同的想法。

相同的代码在控制台应用程序中工作，因此，我假设问题与异步操作的发生方式有关。

我的代码如下：

protected async void Login_click(object sender, EventArgs e)
{
    response1.Text = "Started";
    var tentantID = ConfigurationManager.AppSettings["tenantID"];
    var clientId = ConfigurationManager.AppSettings["applicationID"];
    var secret = ConfigurationManager.AppSettings["secret"];

    await Authorize(tentantID , clientId, secret);
}
private async Task<AuthenticationResult> GetToken(string clientId, string tenantDomain, string clientSecret)
{
    AuthenticationResult result = null;

    var context = new AuthenticationContext("https://login.microsoftonline.com/" + tenantDomain);

    try
    {
        ClientCredential clientCredential = new ClientCredential(clientId, clientSecret);
        return result = await context.AcquireTokenAsync("https://management.core.windows.net/", clientCredential).ConfigureAwait(false);

    }   
    catch (AdalException ae)
    {
        //Error code
        return null;
    }
    catch (Exception e)
    {
        //Error code
        return null;
    }
}

private async Task Authorize(string tenant, string clientId, string clientSecret)
{
    var authenticationResult = await GetToken(clientId, tenant, clientSecret).ConfigureAwait(false);

    string token = authenticationResult.AccessToken;
}

编辑...我更新的代码：

protected void Login_click(object sender, EventArgs e)
{
    response1.Text = "Started";

    RegisterAsyncTask(new PageAsyncTask(Authorize));
}  
public async Task Authorize()
{

    var tentantID = ConfigurationManager.AppSettings["tenantID"];
    var clientId = ConfigurationManager.AppSettings["applicationID"];
    string myKey = ConfigurationManager.AppSettings["myKey"];
    var tenantDomain = ConfigurationManager.AppSettings["tenantDomain"];

    var context = new AuthenticationContext("https://login.microsoftonline.com/" + tenantDomain, false);

    try
    {
        ClientCredential clientCredential = new ClientCredential(clientId, myKey);
        var result = context.AcquireTokenAsync("https://management.core.windows.net/", clientCredential).ConfigureAwait(false);

        AuthenticationResult resVal = await result;
        token = resVal.AccessToken;
    }
    catch (AdalException ae)
    {
        //error code
        token = ae.InnerException.Message;
    }
}
