如何在Delphi中发出HTTPS POST请求？

Question

在Delphi中执行HTTPS POST请求的最简单方法是什么？我在发出HTTP POST请求时遇到问题,但是如何使用SSL呢？我已经google了一下,并没有发现任何能够解释得很好的东西.

这是我试过的代码:

procedure TForm1.FormCreate(Sender: TObject);
var
  responseXML:TMemoryStream;
  responseFromServer:string;
begin
  responseXML := TMemoryStream.Create;
  IdSSLIOHandlerSocketOpenSSL1 := TIdSSLIOHandlerSocketOpenSSL.Create(self);
  with idSSLIOHandlerSocketOpenSSL1 do
    begin
      SSLOptions.Method := sslvSSLv2;
      SSLOptions.Mode := sslmUnassigned;
      SSLOptions.VerifyMode := [];
      SSLOptions.VerifyDepth := 0;
      host := '';
    end;

  IdHTTP1 := TIdHTTP.Create(Self);
  with IdHTTP1 do
    begin
      IOHandler := IdSSLIOHandlerSocketOpenSSL1;
      AllowCookies := True;
      ProxyParams.BasicAuthentication := False;
      ProxyParams.ProxyPort := 0;
      Request.ContentLength := -1;
      Request.ContentRangeEnd := 0;
      Request.ContentRangeStart := 0;
      Request.Accept := 'text/html, */*';
      Request.BasicAuthentication := False;
      Request.UserAgent := 'Mozilla/3.0 (compatible; Indy Library)';
      HTTPOptions := [hoForceEncodeParams];
    end;
  responsefromserver := IdHTTP1.Post('https://.../','name1=value1&name2=value2&....');
end;

当我尝试运行它时,我收到以下错误:

Project myProject.exe raised exception class EFOpenError with message 'Cannot open file "C:\...\Projects\Debug\Win32\name1=value1name2=value2 The system cannot find the file specified'.

我不明白.我发送参数,虽然错误听起来像我会发送文件.

我还在myProject.exe文件夹中包含了libeay32.dll和ssleay32.dll.

您没有指定您的 Delphi 版本或 indy 版本，但我之前使用 Delphi 2009 和 HTTPS 捆绑的 Indy 遇到了一些问题，当我从indy svn获取最新源代码时，问题解决了。
