我正在尝试执行以下操作：

page = Mechanize.new.get "https://sis-app.sph.harvard.edu:9030/prod/bwckschd.p_disp_dyn_sched"

但我只得到这个例外：

OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv2/v3 read server hello A: sslv3 alert illegal parameter

有时你需要告诉 mechanize 使用 sslv3：

page = Mechanize.new{|a| a.ssl_version, a.verify_mode = 'SSLv3', OpenSSL::SSL::VERIFY_NONE}.get "https://sis-app.sph.harvard.edu:9030/prod/bwckschd.p_disp_dyn_sched"

请注意，我使用 OpenSSL::SSL::VERIFY_NONE。这意味着理论上你很容易受到中间人攻击，但这并不是我在抓取网站时通常担心的事情。
