如何告诉dot-netGraph SDK使用自定义代理

Question

我在获取dotnet图sdk以按预期使用代理设置时遇到问题。我曾尝试在使用GraphClientFactory初始化HttpClient时设置代理，但似乎仍然出现了下面显示的异常。这些相同的设置正在传递给ConfidentialClientApplicationBuilder，并用于成功请求身份验证令牌。它还通过相同的代理设置与内部应用程序API进行通信，没有任何问题。有人能帮我指一下正确的方向吗？我使用的是Graph SDK 4.36.0.0的最新版本

public async Task Initialize(WebProxy webProxy)
{
var httpClientFactory = new GraphIntegrationHttpClientFactory(webProxy);
IConfidentialClientApplication daemonClient;
//Creates a daemon service.
daemonClient = ConfidentialClientApplicationBuilder.Create(_clientId)
.WithAuthority(string.Format(Constants.AuthorityFormat, _tenantId))
.WithClientSecret(_clientSecret)
.WithHttpClientFactory(httpClientFactory)
.Build();
//Gets auth token.
AuthenticationResult authResult = await daemonClient.AcquireTokenForClient(new string[] { Constants.MsGraphScope })
.ExecuteAsync();
ClientCredentialProvider authProvider = new ClientCredentialProvider(daemonClient);
var handlers = GraphClientFactory.CreateDefaultHandlers(authProvider);
handlers.Add(new LoggingHandler(_logService));
var httpClient = GraphClientFactory.Create(handlers, proxy: webProxy);
httpClient.Timeout = TimeSpan.FromMinutes(5);
_graphServiceClient = new GraphServiceClient(httpClient);
}

异常

我找到了一种解决这个问题的方法，通过传递一个客户HttpClientHandler，将所有信息设置为GraphClientFactory Create方法的finalhandler参数。我在github页面上打开了一个关于传递代理无法正常工作的新问题。
