执行 GetQYAccessToken 函数报什么错？

全局代码

Public Function CheckValidationResult(sender As Object, certificate As System.Security.Cryptography.X509Certificates.X509Certificate, chain As System.Security.Cryptography.X509Certificates.X509Chain, errors As System.Net.Security.SslPolicyErrors) As Boolean
 ' 总是接受   
 Return True
End Function

AfterOpenProject事件

System.Net.ServicePointManager.ServerCertificateValidationCallback = New System.Net.Security.RemoteCertificateValidationCallback(addressof CheckValidationResult)
