记一个netcore HttpClient的坑

异常信息

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小时奋斗    issues

证书问题 原因不详

　　　　　　　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();
            }

　　

我的环境

system:centos7.2

netcore sdk 2.2

最后附上解决方案

 export DOTNET_SYSTEM_NET_HTTP_USESOCKETSHTTPHANDLER=0;dotnet build

感谢@晓晨 帮助 怎么清除证书

后记 因为有bug存在 用服务器启动还是有问题 最后使用docker彻底解决

2019-9-19实在不想 容器化解决 也有办法  参照我的这篇文章
