Rails5でcookieの中身を見る方法
環境
- Rails 5.2.3
- Ruby 2.6.3
必要な情報
- cookieの値
- secret_key_baseの値
- encrypted_cookie_salt と encrypted_signed_cookie_salt はデフォルト値と想定
- encrypted_cookie_salt (salt) = '
encrypted cookie'
- encrypted_signed_cookie_salt (signed_salt) = '
signed encrypted cookie'
コマンド
def verify_and_decrypt_session_cookie(cookie, secret_key_base)
cookie = CGI::unescape(cookie)
salt = 'encrypted cookie'
signed_salt = 'signed encrypted cookie'
key_generator = ActiveSupport::KeyGenerator.new(secret_key_base, iterations: 1000)
secret = key_generator.generate_key(salt)[0, ActiveSupport::MessageEncryptor.key_len]
sign_secret = key_generator.generate_key(signed_salt)
encryptor = ActiveSupport::MessageEncryptor.new(secret, sign_secret, serializer: JSON)
encryptor.decrypt_and_verify(cookie)
end
cookie = 'cookie value comes here'
secret_key_base = 'secret_key_base value comes here'
verify_and_decrypt_session_cookie(cookie, secret_key_base)
