記一個netcore HttpClient的坑

異常信息

The SSL connection could not be established, see inner exception ---> AuthenticationException: The remote certificate is invalid according to the validation procedure

 

背景

吐血大坑 N小時奮斗    issues  

 

證書問題 原因不詳  

　　　　　　　using (var client = new HttpClient())
            {
                
                client.DefaultRequestHeaders.Add("user-agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/36.0.1985.143 Safari/537.36");
                var html = (client.GetStringAsync("https://*****/").GetAwaiter().GetResult());
                Console.WriteLine(html);
                Console.ReadLine();
            }

　　

我的環境 

system:centos7.2

netcore sdk 2.2

 

最后附上解決方案 

 export DOTNET_SYSTEM_NET_HTTP_USESOCKETSHTTPHANDLER=0;dotnet build

 

感謝@曉晨 幫助 怎么清除證書

 

后記 因為有bug存在 用服務器啟動還是有問題 最后使用docker徹底解決

 

2019-9-19實在不想 容器化解決 也有辦法  參照我的這篇文章
