我使用Rails 4.2.7。如何向Net：：HTTP：：Post请求添加头？我试过了

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

字符串
但是当我运行这段代码时，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'

注意我想在对象被发送之前将头添加到对象中。

您可以使用示例来创建带有标题的帖子

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

字符串

除了T J的方法（将头作为参数提供给post()调用）之外，您还可以使用:[]在HTTPRequest对象本身上设置头：

uri = URI('http://example.com/cached_response')
req = Net::HTTP::Get.new(uri)
req['If-Modified-Since'] = file.mtime.rfc2822

这允许您在执行请求之外设置标头。
同样的方法也适用于Net::HTTP::Post对象：

params = {"SubmitButton" => "View"}
req = Net::HTTP::Post.new(uri, params)
req['Referer'] = url
