vb.net - 验证服务器证书 - ServerCertificateValidationCallback

Question

我正在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 RemoteCertificateChainErrors。如何解决。

Answer 1

您的回调与系统默认验证没有任何不同。 sslPolicyErrors 的值将指示失败是什么，您可以查询证书、链和发件人的属性，以决定是否要通过返回 true 来覆盖失败。
