“根據驗證程序，遠程證書無效?！?使用Gmail SMTP服務器
如何解決“根據驗證程序，遠程證書無效?！?使用Gmail SMTP服務器？
警告：請勿在生產代碼中使用此功能！解決方法是，您可以關閉證書驗證。只有這樣做才能獲得由于證書錯誤而引發錯誤的確認。
在調用之前調用此方法smtpclient.Send()：
[Obsolete("Do not use this in Production code!!!",true)] static void NEVER_EAT_POISON_disable_CertificateValidation() { // disabling certificate validation can expose you to a man-in-the-middle attack // which may allow your encrypted message to be read by an attacker // https://stackoverflow.com/a/14907718/740639 ServicePointManager.ServerCertificateValidationCallback = delegate ( object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors ) { return true; }; }
解決方法
我收到此錯誤：
根據驗證過程，遠程證書無效。
每當我嘗試使用C＃代碼使用Gmail的SMTP服務器發送電子郵件時。有人可以指出我正確的方向來解決這個問題嗎？
