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 from /Users/amosng/.rvm/gems/ruby-1.9.3-p194/gems/net-http-persistent-2.7/lib/net/http/persistent/ssl_reuse.rb:70:in `connect' from /Users/amosng/.rvm/gems/ruby-1.9.3-p194/gems/net-http-persistent-2.7/lib/net/http/persistent/ssl_reuse.rb:70:in `block in connect' from /Users/amosng/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/timeout.rb:54:in `timeout' from /Users/amosng/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/timeout.rb:99:in `timeout' from /Users/amosng/.rvm/gems/ruby-1.9.3-p194/gems/net-http-persistent-2.7/lib/net/http/persistent/ssl_reuse.rb:70:in `connect' from /Users/amosng/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/net/http.rb:755:in `do_start' from /Users/amosng/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/net/http.rb:750:in `start' from /Users/amosng/.rvm/gems/ruby-1.9.3-p194/gems/net-http-persistent-2.7/lib/net/http/persistent.rb:511:in `connection_for' from /Users/amosng/.rvm/gems/ruby-1.9.3-p194/gems/net-http-persistent-2.7/lib/net/http/persistent.rb:806:in `request' from /Users/amosng/.rvm/gems/ruby-1.9.3-p194/gems/mechanize-2.5.1/lib/mechanize/http/agent.rb:258:in `fetch' from /Users/amosng/.rvm/gems/ruby-1.9.3-p194/gems/mechanize-2.5.1/lib/mechanize.rb:407:in `get' from (irb):549 from /Users/amosng/.rvm/rubies/ruby-1.9.3-p194/bin/irb:16:in `<main>'
如何在“Mechanize”中加载网页?
解决方法
有时您需要告诉机械化使用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.这意味着你在理论上容易受到中间人的攻击,但是当我在刮网站时,这并不是我一般担心的.
