访问https服务器上托管的Webservice
我正在访问一个在SSL认证的网络服务器中托管的webserivce https://www.example.net/somewebservice/somemethod.asmx
但是当我创建一个代理类并使用C＃消费它时：我收到了这个错误

您的SSL证书似乎是自签名的，或者不是来自受信任的CA的自签名
System.Net.WebException：基础连接已关闭：无法为SSL / TLS安全通道建立信任关系。
让我相信……最简单的解决方案： 安装一个值得信赖的证书 ……
绝对不适合生产
其他解决方案是修改客户端validation
public class TrustAllCertificatePolicy : System.Net.ICertificatePolicy { public TrustAllCertificatePolicy() {} public bool CheckValidationResult(ServicePoint sp, X509Certificate cert,WebRequest req, int problem) { return true; } } // this needs to be done once before the first webservice call System.Net.ServicePointManager.CertificatePolicy = new TrustAllCertificatePolicy(); 见http://weblogs.asp.net/jan/archive/2003/12/04/41154.aspx
看起来你的服务器提供了无效的SSL证书… 结账这篇文章应该有助于避免这个问题。
