ruby - 如何在ruby中模拟http post请求和解析html响应

Question

我正在尝试模拟与此网页上的表单相关的 http 请求: http://www.ei.applipub-fft.fr/eipublic/competitionRecherche.do然后我需要解析响应 html。

我正在尝试使用 gem 'webmock' 和 'rest-client'。所以在研究了原始的 http 请求之后，我尝试了类似的东西:

def post
  stub_request(:post, "http://www.ei.applipub-fft.fr/eipublic/competitionRecherche.do").
      with(:body => {"data"=>{"dispatch"=>"filtrer", "hoi_atp"=>"T", "dtdate"=>"30/12/2015", "mois"=>"12", "multi_lig_cod"=>"0", "lig_cno_1"=>"01", "bidf"=>"0", "imit_categ_age"=>"0", "hoiCtmcDames"=>"T"}},
           :headers => {'Accept'=>'*/*; q=0.5, application/xml', 'Accept-Encoding'=>'gzip, deflate', 'Content-Length'=>'174', 'Content-Type'=>'application/x-www-form-urlencoded', 'User-Agent'=>'Ruby'}).
      to_return(:status => 200, :body => "", :headers => {})

 resp = RestClient.post('http://www.ei.applipub-fft.fr/eipublic/competitionRecherche.do', "data[dispatch]=filtrer&data[hoi_atp]=T&data[dtdate]=30/12/2015&data[mois]=12&data[multi_lig_cod]=0&data[lig_cno_1]=01&data[bidf]=0&data[imit_categ_age]=0&data[hoiCtmcDames]=T",
  :content_type => 'application/x-www-form-urlencoded')
 puts resp a
end

但我无法获得正确的 html 响应。谁能解释这一切是如何运作的？

我通常会使用 HTTParty gem 来完成。它允许您使用 Ruby 编写发布请求。示例:

HTTParty.post('http://example.com/post_here', 
  body: { subject: 'This is the screen name', 
          description: 'This is the description for the problem'
        }.to_json,
  headers: { 'Content-Type' => 'application/json' } )
