Indy 10.6.0.5169 + OpenSSL 1.0.2u + Delphi XE7，握手错误 [英] Indy 10.6.0.5169 + OpenSSL 1.0.2u + Delphi XE7, handshake error

问题描述

我想使用Indy从网站上获取数据，但无法正常工作.我收到以下错误:

I would like to get data from a website using Indy, but its not working. I get the following error:

使用SSL连接时出错.
错误:14077410:SSL例程:SSL23_GET_SERVER_HELLO:sslv3警报握手失败

Error connecting with SSL.
error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure

这是代码:

var
  AMS: TMemoryStream;
begin
  AMS := TMemoryStream.Create;
  try
    IdHTTP1.Get('https://www.optionsprofitcalculator.com/ajax/getStockPrice?stock=hca&reqId=0', AMS);
    AMS.SaveToFile('c:\test.txt');
  finally
    FreeAndNil(AMS);
  end;
end;

以及组件:

object IdHTTP1: TIdHTTP
  IOHandler = IdSSLIOHandlerSocketOpenSSL1
  AllowCookies = True
  HandleRedirects = True
  ProxyParams.BasicAuthentication = False
  ProxyParams.ProxyPort = 0
  Request.Connection = 'keep-alive'
  Request.ContentLength = -1
  Request.ContentRangeEnd = -1
  Request.ContentRangeStart = -1
  Request.ContentRangeInstanceLength = -1
  Request.Accept = 
    'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp' +
    ',*/*;q=0.8'
  Request.AcceptEncoding = 'gzip, deflate, br'
  Request.AcceptLanguage = 'hu-HU,hu;q=0.8,en-US;q=0.5,en;q=0.3'
  Request.BasicAuthentication = False
  Request.UserAgent = 
    'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:77.0) Gecko/20100101' +
    ' Firefox/77.0'
  Request.Ranges.Units = 'bytes'
  Request.Ranges = <>
  HTTPOptions = [hoForceEncodeParams]
  Left = 110
  Top = 155
end
object IdSSLIOHandlerSocketOpenSSL1: TIdSSLIOHandlerSocketOpenSSL
  MaxLineAction = maException
  Port = 0
  DefaultPort = 0
  SSLOptions.Method = sslvSSLv23
  SSLOptions.SSLVersions = [sslvSSLv2, sslvSSLv3, sslvTLSv1, sslvTLSv1_1, sslvTLSv1_2]
  SSLOptions.Mode = sslmUnassigned
  SSLOptions.VerifyMode = []
  SSLOptions.VerifyDepth = 0
  Left = 155
  Top = 155
end

我不知道问题出在哪里.如果Indy无法实现，我想知道是否有任何标准的Delphi组件与HTTPS服务器通信?

I have no clue where the problem is. If it cannot be achieved with Indy, I would like to know if there is any standard Delphi component to communicate with HTTPS servers?

推荐答案

奥秘得以解决.

提到的网站使用的是Indy尚不支持的TLS 1.3.

The mentioned site using TLS 1.3 which not supported by the Indy, yet.
