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
