Xamarin IOSのWeb APIにヒットしたときにfaliureの問題が発生しました

Question

Xamarin IOSプロジェクトのWeb APIにヒットしたときに、しばらく私はConnect Failureの問題に直面しています。 APIは正常に動作しており、問題は関連しています。いずれかの人がこの問題を解決するアイデアを持っている場合、または私はこの問題を解決することができるリンクを持っています。 私は多くの解決策を試したが解決できなかったので私に送ってください。

Answer 1

どのくらいの頻度では、Web APIを呼び出すのですか？

私は前にこの問題があります。

マイコード：

HttpClient client = new HttpClient(); 
... 
HttpResponseMessage response = await client.PostAsync (“webapi url” , postContent); 

ソリューション： https://dotblogs.com.tw/rainmaker/2016/06/06/103035

希望します：

using(HttpClient client = new HttpClient()) 
{ 
    ... 
    HttpResponseMessage response = await client.PostAsync("webapi url" , postContent); 
    ... 
} 

それはあなたが

にHttpClientをを配置していないようにこのページを見ることができるようですそれを修正することができます
