Question

我正在使用Delphi 2007和Indy 10来发布https帖子请求，我正在使用httpbin进行测试，但它不起作用......它正在提升：

First chance exception at $77503E28. Exception class EIdOSSLCouldNotLoadSSLLibrary with message 'Could not load SSL library.'. Process Recarga.exe (21392)

这是我的代码：

unit UMAIN;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, IdHttp, IdMultipartFormData, IdSSLOpenSSL;

type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
const
  URL = 'https://httpbin.org/post';
var
  idHttp: TIdHTTP;
  data: TIdMultiPartFormDataStream;
  retorno: string;
  LHandler: TIdSSLIOHandlerSocketOpenSSL;
begin
  idHttp:= TIdHTTP.Create(nil);
  data := TIdMultiPartFormDataStream.Create;
  LHandler := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
  with LHandler do
    begin
      SSLOptions.Method := sslvSSLv2;
      SSLOptions.Mode := sslmUnassigned;
      SSLOptions.VerifyMode := [];
      SSLOptions.VerifyDepth := 0;
      host := '';
    end;

  data.AddFormField('serv', 'atualizar');

  try
    try
      idHttp.IOHandler := LHandler;
      idHttp.Request.Accept := 'text/html, */*';
      idHttp.Request.UserAgent := 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:25.0) Gecko/20100101 Firefox/25.0';
      idHttp.Request.ContentType := 'application/x-www-form-urlencoded';
      idHttp.HandleRedirects := True;
      retorno := UTF8Decode(idHttp.Post(URL, data));
      ShowMessage('Resultado: ' + retorno);
    except on E: Exception do
      ShowMessage('Erro: ' + E.Message);
    end;
  finally
    LHandler.Free;
    idHttp.Free;
  end;

end;

end.

我在SO和其他网站上阅读了我需要 libeay32.dll 和 ssleay32.dll 库但我确实拥有它们并且位于我所在的同一目录中最后的exe，没有任何作用，正如我上面所说。怎么了？这是一个错误吗？

Answer 1

我必须在上班前测试很多dll，根据this回答我需要一个特定版本的dll。经过努力和测试所有openssl版本provided by Indy后，9.6 one为我工作。
