SSL通信-证书认证错误忽略

.NET的SSL通信过程中，使用的证书可能存在各种问题，某种情况下可以忽略证书的错误继续访问。

经过下面的处理服务器证书验证中不会有错误发生，证书认证一直通过，并正常通信

1.设置回调属性ServicePointManager.ServerCertificateValidationCallback

注：这个属性设置为要用于客户端的服务器证书的自定义验证方法

C#代码

1 ServicePointManager.ServerCertificateValidationCallback =
2           new RemoteCertificateValidationCallback(
3                    OnRemoteCertificateValidationCallback); 

VB.NET代码

1 ServicePointManager.ServerCertificateValidationCallback = _
2           New RemoteCertificateValidationCallback( _
3                     AddressOf OnRemoteCertificateValidationCallback) 

2.把证书认证函数OnRemoteCertificateValidationCallback返回值True

C#代码

1 // 忽略证书认证错误处理的函数
2 private bool OnRemoteCertificateValidationCallback(
3   Object sender,
4   X509Certificate certificate,
5   X509Chain chain,
6   SslPolicyErrors sslPolicyErrors)
7 {
8   return true;  // 认证正常，没有错误
9 } 

VB.NET代码

‘ 忽略证书认证错误处理的函数
Private Function OnRemoteCertificateValidationCallback( _
  ByVal sender As Object, _
  ByVal certificate As X509Certificate, _
  ByVal chain As X509Chain, _
  ByVal sslPolicyErrors As SslPolicyErrors _
) As Boolean
  Return True  ‘ 认证正常，没有错误End Function
