ValidateServerCertificate - ServerCertificateValidationCallback

Question

我使用以下代码进行证书验证。

System.Net.ServicePointManager.ServerCertificateValidationCallback = New System.Net.Security.RemoteCertificateValidationCallback(AddressOf ValidateServerCertificate)

Public Shared Function ValidateServerCertificate(ByVal sender As Object, ByVal certificate As X509Certificate, ByVal chain As X509Chain, ByVal sslPolicyErrors As Net.Security.SslPolicyErrors) As Boolean
    If sslPolicyErrors = Net.Security.SslPolicyErrors.None Then
        Return True
    End If
    Return False
End Function

我收到了RemoteCertificateChainErrors。如何解决它。

您的回调并未执行与系统默认验证不同的任何操作。 sslPolicyErrors的值将指示失败是什么，并且您可以查询证书，链和发送方的属性，以决定是否要通过返回true来覆盖失败。
