Question

所以，基本上我试图运行这个脚本https://github.com/JeffreyATW/mbfc_crawler，它给了我 这个错误：

C:/Ruby23-x64/lib/ruby/2.3.0/net/http.rb:933:in `connect_nonblock': SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A (OpenSSL::SSL::SSLError)

我已经从Ruby Installer for Windows安装了Ruby 2.3.3。

我还为我的机器（来自同一站点）安装了DevKit-mingw64-64-4.7.2-20130224-1432-sfx.exe。

我做错了什么？谢谢你的时间。

Answer 1

也许它需要CA证书。

从此处将其保存在您的m / c中：concatMap

使用以下命令设置路径：

setx SSL_CERT_FILE path_where_you_have_placed_above_file

Answer 2

停止使用SSLv3，并开始使用TLS 1.0（或更高版本）和Server Name Indication (SNI)。

这是你在Ruby上做的事情：

这是你应该用Ruby做什么的。注意TLS 1.0和SNI：

$ openssl s_client -connect github.com:443 -ssl3
CONNECTED(00000003)
3069617360:error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure:s3_pkt.c:1275:SSL alert number 40
