[bug]The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

写在前面

在模拟请求的时候，如果url为https的，会报这个错误。大概错误就是：基础连接已关闭：无法建立信任关系的SSL / TLS的安全通道。

      The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

基础连接已关闭：无法建立信任关系的SSL / TLS的安全通道。

解决办法

在模拟请求的方法中加上这样一句话。

 ServicePointManager.ServerCertificateValidationCallback = new System.Net.Security.RemoteCertificateValidationCallback((obj, certificate, chain, sslPolicyErrors) =>
                {
                    return true;
                });
