C# .NET HttpWebRequest 按每个（单个）请求跳过证书校验

C# .NET HttpWebRequest 按每个（单个）请求跳过证书校验

自签名证书 HTTPS TLS 。

使用.NET 4.5 新加的属性 HttpWebRequest.ServerCertificateValidationCallback。

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

request.ServerCertificateValidationCallback = (_s, _x509s, _x509c, _ssl) => { return (true); };

.NET 4.5 之前只能用全局的配置：

ServicePointManager.ServerCertificateValidationCallback

System.Net.ServicePointManager.ServerCertificateValidationCallback += (s, cert, chain, sslPolicyErrors) => true;

ServicePointManager.SecurityProtocol。
