Delphi XE SOAP SSL

我有一个在Delphi 2009上编写的程序.它使用SOAP over HTTP over SSL.因此,SOAP请求会触发HTTP请求,该请求由Microsoft Internet Explorer通过DLL处理.然后MSIE将弹出一个要求登录的弹出窗口.

但现在我需要在Delphi XE中编译它,我遇到了问题.程序不想登录SSL.根本没有弹出窗口.所以,似乎触发器不想工作.

该错误出现在此代码的第二行：

mantis:=GetMantisConnectPortType(false,mantisurl);
mi := mantis.mc_issue_get(username,password,MantisIssue);

错误是

Project IssueReporter.exe raised exception class ESOAPHTTPException with message 'Authorization Required (401) - 'https://***/mantis/api/soap/mantisconnect.php''.

连接过程列表是

function GetMantisConnectPortType(UseWSDL: Boolean; Addr: string; HTTPRIO: THTTPRIO): MantisConnectPortType;
const
  defWSDL = 'https://***/mantis/api/soap/mantisconnect.php?wsdl';
  defURL  = 'https://***/mantis/api/soap/mantisconnect.php';
  defSvc  = 'MantisConnect';
  defPrt  = 'MantisConnectPort';
var
  RIO: THTTPRIO;
begin
  Result := nil;
  if (Addr = '') then
  begin
    if UseWSDL then
      Addr := defWSDL
    else
      Addr := defURL;
  end;
  if HTTPRIO = nil then
    RIO := THTTPRIO.Create(nil)
  else
    RIO := HTTPRIO;
  try
    Result := (RIO as MantisConnectPortType);
    if UseWSDL then
    begin
      RIO.WSDLLocation := Addr;
      RIO.Service := defSvc;
      RIO.Port := defPrt;
    end else
      RIO.URL := Addr;
  finally
    if (Result = nil) and (HTTPRIO = nil) then
      RIO.Free;
  end;
end;

mc_issue_get是其中的一部分

MantisConnectPortType = interface(IInvokable)

有声明：

function  mc_issue_get(const username: string; const password: string; const issue_id: Int64): IssueData; stdcall;

在浏览器和2009年编译的旧exe中,一切正常.请帮忙解决这个问题.
