Rails不识别从Ruby脚本发布的参数

Question

我有一个带有create方法的Rails控制器,我想从Ruby脚本发布它.当我从基于浏览器的POST中点击此方法时,params哈希值被适当地设置,但是当我从脚本中点击它时,哈希是空的.我已经禁用了protect_from_forgery,并且该方法被调用; 它只是一个空的params.这是控制器方法:

def create
  logger.info "GOT: #{request.body.read}"
  logger.info "PARAMS: #{params.inspect}"
  az = AreaZip.new(params[:area_zip])
  if az.save
    respond_to { |format|
      format.js { render :json => {:id => az.id} }
    }
  else
    logger.warn "FAILED creating AreaZip: #{az.errors.inspect}"
    respond_to { |format|
      format.js { render :json => {:errors => az.errors} }
    }
  end
end

以下是发布帖子的代码:

def self.post(url, path, params={})
  url = "#{url}#{path}"
  uri = URI.parse(url)
  headers = {
    'Content-Type' => 'text/plain; charset=utf-8',
    'Authorization' => "Basic #{Base64.encode64('censored:censored').strip}",
  }

  http = Net::HTTP.new(uri.host, uri.port)
  post_data = params.map {|k,v| "#{CGI::escape(k.to_s)}=#{CGI::escape(v.to_s)}" }.join("&")
  resp, data = http.post(uri.path, post_data, headers)
  return JSON.parse(data)
end   

以下是我发布的内容nc -l -p 12345:

POST /admin/area_zips HTTP/1.1
Accept: */*
Connection: close
Content-Type: text/plain; charset=utf-8
Authorization: Basic sdfnjjsadf[censored]jklsdfsjdfkj
Content-Length: 54
Host: localhost:12345

area_zip%5Bzip%5D=15068-4838&area_zip%5Barea_id%5D=334

如果我发布到我的Rails应用程序,我的日志显示:

Started POST "/admin/area_zips" for 127.0.0.1 at Fri Jul 29 09:45:05 -0400 2011
  Processing by Admin::AreaZipsController#create as */*

正如您所看到的,Rails获取POSTed数据,但它没有使用它来设置params.知道为什么吗？

好的,我解决了这个问题.原来问题是Content-Type标题.我需要设置它application/x-www-form-urlencoded.其实我以为我是这样做的,但显然不是.旧的Content-Type值是一个复制粘贴错误,从我get方法中的代码中删除.
