public static class Util { //由于api的特殊性，需要在我们发出请求前，解决未能建立安全通信通道问题，为这次连接设置安全认证 public static void SetCertificatePolicy() { ServicePointManager.ServerCertificateValidationCallback += RemoteCertificateValidate; } private static bool RemoteCertificateValidate( object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors error) { // trust any certificate!!! System.Console.WriteLine("Warning, trust any certificate"); return true; } } |
写一个utils类，当你在

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url); |
上面这个代码前添加这个方法 Util.SetCertificatePolicy(); 为本次连接设置证书。 from:https://blog.csdn.net/quentien/article/details/122326973
