为什么Chilkat Http会在“ https”上遇到握手错误，而在“ http”上却遇到握手错误？

问题描述

“ http”地址工作正常。 “ https”版本给我一个握手错误：

这是我致电以下电话时收到的错误：

Dim lSuccess&
lSuccess = nHttp.Download("https://autoconfig.thunderbird.net/v1.1/gmx.de","d:\weg.xml") 

lSuccess返回0，表示发生错误。

解决方法

您使用的是奇尔卡特的旧版本。将Chilkat更新到最新版本。多年来，TLS和TLS服务器要求不断发展。当外部世界总是在变化的时候，人们不能指望任何实现永远有效。
