我可以知道怎样处理垃圾吗？还是我真的需要处理掉它因为微软也在处理1https://learn.microsoft.com/en-us/dotnet/api/system.net.http.httpclienthandler?view=netcore-3.1
这是我的静态图。

private static HttpClientHandler handlerWithProxy = new HttpClientHandler
        {
            UseCookies = false,
            UseDefaultCredentials = true,
            DefaultProxyCredentials = CredentialCache.DefaultCredentials,
            Proxy = new WebProxy($"{MyProxy.ProxyHost}:{MyProxy.ProxyPort}", false),
            UseProxy = true,
            SslProtocols = SslProtocols.Tls12 | SslProtocols.Tls11 | SslProtocols.Tls,
            ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; }
        };

我在这里宣布弃尸。这是正确的吗？

private static async Task<JsonDocument> ResponseMessage(HttpRequestMessage request, CancellationToken token)
    {
        HttpCompletionOption option = HttpCompletionOption.ResponseHeadersRead;

        using (HttpResponseMessage response = MyProxy.UseProxy ? await clientWithProxy.SendAsync(request, option, token).ConfigureAwait(false)
                                                       : await client.SendAsync(request, option, token).ConfigureAwait(false))
        {
            token.ThrowIfCancellationRequested();
            HttpStatusCode status = response.StatusCode;

            using (Stream stream = await response.Content.ReadAsStreamAsync().ConfigureAwait(false))
            {
                if (stream == null || stream.CanRead == false) { return default; }

                var options = new JsonDocumentOptions { AllowTrailingCommas = true };
                var json = await JsonDocument.ParseAsync(stream, options).ConfigureAwait(false);

                if (!response.IsSuccessStatusCode) { throw new InvalidDataException($"Error occured: {ParseError(uri, json, status)}"); }

                //is this right of calling the dispose if it is already null?
                if (handler == null) { handler.Dispose(); }

                return json;
            }
        }
    }
