取得或設定驗證伺服器憑證的回呼方法。 此回呼是 SSL 信號交換的一部分。

public:
 property Func<System::Net::Http::HttpRequestMessage ^, System::Security::Cryptography::X509Certificates::X509Certificate2 ^, System::Security::Cryptography::X509Certificates::X509Chain ^, System::Net::Security::SslPolicyErrors, bool> ^ ServerCertificateValidationCallback { Func<System::Net::Http::HttpRequestMessage ^, System::Security::Cryptography::X509Certificates::X509Certificate2 ^, System::Security::Cryptography::X509Certificates::X509Chain ^, System::Net::Security::SslPolicyErrors, bool> ^ get(); void set(Func<System::Net::Http::HttpRequestMessage ^, System::Security::Cryptography::X509Certificates::X509Certificate2 ^, System::Security::Cryptography::X509Certificates::X509Chain ^, System::Net::Security::SslPolicyErrors, bool> ^ value); };

public Func<System.Net.Http.HttpRequestMessage,System.Security.Cryptography.X509Certificates.X509Certificate2,System.Security.Cryptography.X509Certificates.X509Chain,System.Net.Security.SslPolicyErrors,bool>? ServerCertificateValidationCallback { get; set; }

member this.ServerCertificateValidationCallback : Func<System.Net.Http.HttpRequestMessage, System.Security.Cryptography.X509Certificates.X509Certificate2, System.Security.Cryptography.X509Certificates.X509Chain, System.Net.Security.SslPolicyErrors, bool> with get, set

Public Property ServerCertificateValidationCallback As Func(Of HttpRequestMessage, X509Certificate2, X509Chain, SslPolicyErrors, Boolean)

屬性值

Func<HttpRequestMessage,X509Certificate2,X509Chain,SslPolicyErrors,Boolean>

如果伺服器證書被視為有效且應該傳送要求，則回呼應該傳回 true 。 否則，傳回 false。

備註

預設值是 null。 如果此屬性為 null，則會使用標準已知證書頒發機構單位來驗證伺服器證書。
