如何在Ruby中向Net :: Http :: Post请求添加标头？

Question

我正在使用Rails 4.2.7。 如何将标头添加到Net :: HTTP :: Post请求？ 我试过了

    params = {"SubmitButton" => "View"}
    …
      headers = {"Referer" => url}
      req = Net::HTTP::Post.new(uri, params.to_query, headers)

但是，当我运行此代码时，我得到了错误

Error during processing: wrong number of arguments (given 3, expected 1..2)
/Users/davea/.rvm/rubies/ruby-2.3.0/lib/ruby/2.3.0/net/http/request.rb:14:in `initialize'
/Users/davea/Documents/workspace/myproject/app/services/marathon_guide_race_finder_service.rb:97:in `new'

/Users/davea/.rvm/gems/ruby-2.3.0/gems/nokogiri-1.6.8/lib/nokogiri/xml/node_set.rb:186:in `each'

注意我要在发送对象之前将标头添加到对象。

您可以使用实例制作带有标题的帖子

headers  = {"Referer" => url}
http     = Net::HTTP.new(uri.host)
response = http.post(uri.path, params.to_query, headers)
