Question

我正在开发一个Rails应用程序，该应用程序向Seamless.gov API发出GET请求以获取表单字段。当我运行以下curl命令时，我可以执行JSON响应。但是，当我从rails上执行操作时，会出现错误：

{“ error”：true，“ error_log”：[{“ error_code”：“ missing_header”， “ error_message”：“请求缺少标头：Authorization”， “错误说明”： “ {\”主机\“：\” nycopp.seamlessdocs.com \“，\”连接\“：\”关闭\“，\” X-

这是我创建的代码：

require 'openssl'
require 'base64'

module SeamlessGov
  class Form
    include HTTParty
    attr_accessor :form_id
    base_uri "https://nycopp.seamlessdocs.com/api"

    def initialize(id)
      @api_key = ENV['SEAMLESS_GOV_API_KEY']
      @signature = generate_signature
      @form_id = id
      @timestamp = Time.now.to_i
    end

    def relative_uri
      "/form/#{@form_id}/elements"
    end

    def create_form
      self.class.get(relative_uri, generate_headers)
    end

    private

    def generate_signature
      OpenSSL::HMAC.hexdigest('sha256', ENV['SEAMLESS_GOV_SECRET'], "GET+#{relative_uri}+#{@timestamp}")
    end

    def generate_headers
      {
        "Authorization"  => "HMAC-SHA256 api_key='#{@api_key}' signature='#{@signature}'",
        "AuthDate" => "#{@timestamp}"
      }
    end
  end
end

在控制器中，我以如下形式传递id：

def display_form
    @form = SeamlessGov::Form.new(ENV['FORM_ID']).create_form
end

标题是否传递错误？

这解决了问题：

self.class.get(relative_uri, headers: generate_headers)

httparty GET请求：“请求缺少标头：“授权”
