ruby – 如何让Mechanize自动将body转换为UTF8？

请参阅Mechanize文档：

pre_connect_hooks()

A list of hooks to call before retrieving a response. Hooks are called with the agent,the URI,the response,and the response body.

post_connect_hooks()

A list of hooks to call after retrieving a response. Hooks are called with the agent,and the response body.

现在您无法更改内部response-body值,因为参数不是数组.所以,下一个最好的方法是用你自己的内部解析器替换：

class MyParser
  def self.parse(thing,url = nil,encoding = nil,options = Nokogiri::XML::ParSEOptions::DEFAULT_HTML,&block)
    # insert your conversion code here. For example:
    # thing = NKF.nkf("-wm0X",thing).sub(/Shift_JIS/,"utf-8") # you need to rewrite content charset if it exists.
    Nokogiri::HTML::Document.parse(thing,url,encoding,options,&block)
  end
end

agent = Mechanize.new
agent.html_parser = MyParser
page = agent.get('http://somewhere.com/')
