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)

然而，当我运行此代码时，我收到错误

Error during processing: wrong number of arguments (given 3, expected 1..2)

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

注意我想在发送之前将标题添加到对象中。

您可以使用该实例制作带标题的帖子

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

如何在Ruby中向Net :: Http :: Post请求添加标头？
