ruby - 如何在使用 Ruby Mechanize 加载页面之前设置 Referer header ？

Question

是否有直接的方法来使用 Mechanize 2.3 设置自定义 header ？

我尝试了 former solution但是得到:

$agent = Mechanize.new
$agent.pre_connect_hooks << lambda { |p|
  p[:request]['Referer'] = 'https://wwws.mysite.com/cgi-bin/apps/Main'
} 

# ./mech.rb:30:in `<main>': undefined method `pre_connect_hooks' for nil:NilClass (NoMethodError)

Answer 1

The docs说:

get(uri, parameters = [], referer = nil, headers = {}) { |page| ... }

例如:

agent.get 'http://www.google.com/', [], agent.page.uri, {'foo' => 'bar'}

或者你可能喜欢:

agent.request_headers = {'foo' => 'bar'}
agent.get url
