Question

我的任务是将this javascript file重建为ruby，但我收到的回复对我来说没有意义（错误）：

{"api_error_code"=>1, "message"=>"Parameter 'username_or_email' is required.", "code"=>"API_ERROR", "target"=>"<webapp.resources.user_session_resource.UserSessionResource object at 0xb8e2a90>", "http_status"=>400}

这没有任何意义，因为我确实提供了username_or_email参数，你可以在这里看到我在做出请求之前对身体进行了放置：

{"source_url":"/login/","data":"{\"options\":{\"username_or_email\":\"testusername@host.com\",\"password\":\"testpassword\"},\"context\":{}}","module_path":"App()>LoginPage()>Login()>Button(class_name=primary, text=Log In, type=submit, size=large)"}

通过执行@curl.post_body = payload或@curl.http_post(payload)或@curl.http_post(url,payload)来设置有效负载似乎也无关紧要，它只是响应相同的错误。顺便提一下，@curl是Curl::Easy的实例。

我已经匹配了json数据请求，因为原来它已经发生了什么？

到目前为止，这是请求：

require_relative "curb_dsl"
require 'json'
module Pin
  class Client
    Login_URL = "https://www.pinterest.com/resource/UserSessionResource/create/"
    Repin_URL = "https://www.pinterest.com/resource/RepinResource/create/"
    include Curb_DSL
    class << self
      def login(username_or_email, password)
        self.new do
          set_uri Login_URL
          header 'Accept', 'application/json, text/javascript, */*; q=0.01'
          header 'Accept-Language', 'en-US,en;q=0.5'
          header 'Cache-Control', 'no-cache'

          header 'X-CSRFToken', 'K4C0QUu35Eoq1xjajbMluw7hOKibpQSW'

          header 'X-Pinterest-AppState', 'active'
          header 'X-Requested-With', 'XMLHttpRequest'
          set_cookies({ ":_auth" => '0',csrftoken: 'K4C0QUu35Eoq1xjajbMluw7hOKibpQSW'})

          set_payload({
            source_url: "/login/",
            data: {
              options: {
                username_or_email: username_or_email,
                password: password
              },
              context: {}
          }.to_json,
            module_path: "App()>LoginPage()>Login()>Button(class_name=primary, text=Log In, type=submit, size=large)"
          })
          set_type_converter -> (payload) {payload.to_json}
          set_error_handler -> {
            JSON.parse(body)['resource_response']['error'].to_s
          }
          puts post_body
          post
          @csrftoken = resp_cookies['csrftoken']
        end
      end
    end
  end
end

好的，所以我发现问题，在分析了与javascript相同但用PHP编写的内容（link）后，我意识到我发布的数据不正确，我需要发送数据，而不是JSON但是当查询字符串（k = v＆amp; k = v）改变时：

 PDFKit.configure do |config|
   config.wkhtmltopdf = '/path/to/wkhtmltopdf'
 end

到

set_type_converter -> (payload) {payload.to_json}

导致set_type_converter -> (payload) {query_params(payload)}为：

post_body

似乎已经解决了这个问题。
