誰能幫我？
我正在 Windows PC 上的 Visual Studio 2022 中開發 Xamarin Forms 應用程式。我將 VS 連接到 MacinCloud Mac 和連接到 Windows PC 的 iPhone。
我的應用程式在 iPhone 上部署并啟動，但是當我登錄時它崩潰了。
它崩潰的代碼行是呼叫 HttpClient.PostAsync 以回呼我們的 API 進行身份驗證。
錯誤和故障轉儲如下。
有任何想法嗎？
謝謝，
保羅。

uj5u.com熱心網友回復：
我已經設法通過創建一個處理程式并將其傳遞給我的 Http 客戶端的建構式來解決這個問題。
var handler = new HttpClientHandler();
var httpClient = new HttpClient(handler);
我以為我之前已經嘗試過這個解決方案但無濟于事，但我找到了第二個地方，它正在創建客戶端并在那里實作它，也解決了這個問題。
