rubyのスクレイピングツールmechanizeでhttps://test.comへ通信をしようとしたら以下のエラーが出ました。

エラーとなったrubyのコードは以下↓

require 'mechanize'

module Crawler
 class testtest
 def login
 agent = Mechanize.new
 # agent.verify_mode = OpenSSL::SSL::VERIFY_NONE
 agent.user_agent = 'Windows Mozilla'
 agent.get('https://test.com') do |page|
 # 何か処理をしようとした
 end
 end
 end
end

crawler = Crawler::testtest.new
crawler.login

require 'mechanize'

module Crawler

class testtest

def login

agent = Mechanize.new

# agent.verify_mode = OpenSSL::SSL::VERIFY_NONE

agent.user_agent = 'Windows Mozilla'

agent.get('https://test.com') do |page|

# 何か処理をしようとした

end

crawler = Crawler::testtest.new

crawler.login

windowsから動かしたのでwindowsにopensslを入れてみるやり方もやってみたが解消されず、他のやり方を探したところ以下のコードに変えたら出来ました。

require 'mechanize'

module Crawler
 class testtest
 def login
 agent = Mechanize.new
 agent.verify_mode = OpenSSL::SSL::VERIFY_NONE  # この行を追加
 agent.user_agent = 'Windows Mozilla'
 agent.get('https://test.com') do |page|
 # 何か処理をしようとした
 end
 end
 end
end

crawler = Crawler::testtest.new
crawler.login
