Delphi 連接 SSL TLS 1.2 第三方支付金流問題

台灣最近銀行與第三方支付、行動支付發展越來越快，而Delphi使用indy元件時，如果處理SSL網站時不是很容易。
後來找到了ipwork的元件還不錯用。
列一下關鍵的程式

  ipwhttp1 := Tipwhttp.Create(Application);
 ipwhttp1.Config('CodePage=65001');
 posturl:=posturl+'barcode='+sBarcode;
 ipwhttp1.Post(sPaymentURL+'?'+posturl); 
 result:=UTF8ToString(ipwhttp1.TransferredData);
  ipwhttp1.free;

另外處理像SHA/AES等加解密也很方便

function GetTokenKey(s:String):String;
var ipcHash1: TipcHash;
begin
  ipcHash1 := TipcHash.Create(Application);
  ipcHash1.Reset();
  ipcHash1.Algorithm := TipcHashAlgorithms(haSHA256);
  ipcHash1.InputMessage := s;    
  ipcHash1.ComputeHash();
  result :=lowercase(ipcHash1.HashValue);
  ipcHash1.Free;
end;

終於完成了Delphi XE 10.2.3的升級 感謝embarcadero及台灣QCom


今年3月份embarcadero發佈10.2.3升級後，卻發生一直無法正常解除10.2.2的問題，後來求助台灣QCom捷康的幫忙後也無法解決，台灣捷康幫忙與總部聯繫。在連假第三天終於解決了！感謝台灣捷康Eddie Chang以及embarcadero support。
