rest-client - 如何使用 ruby​​ 的 rest-client 发布图像？

Question

我正在尝试找到一种使用 Postful API 的方法，我需要在请求正文中发布图像。我正在尝试使用rest-client（但对其他方式持开放态度）：

我发布时收到的错误是 HTTP 状态代码 422

基本上，我一无所知，需要指导。:\

class PostfulsController < ApplicationController
  require 'rest_client'

  def submit

    body = "<?xml version='1.0' encoding='UTF-8'?>
               <mail>
                <documents>
                  <document>
                    <template>
                      <source>gallery</source>
                      <name>Postcard: Image fit front</name>
                    </template>
                    <sections>
                       <section>
                         <name>Text</name>
                         <text>Hello, World!</text>
                        </section>
                     <section>
                        <name>Image</name>
                        <attachment>#{attachment_id}</attachment>
                        </section>
                     </sections>
                  </document>
                </documents>
                <addressees>
                  <addressee>
                    <name>John Doe</name>
                    <address>123 Main St</address>
                    <city>Anytown</city>
                    <state>AZ</state>
                    <postal-code>10000</postal-code>
                  </addressee>
                </addressees>
              </mail>"

      result = RestClient.post 'http://www.postful.com/service/mail', 
               body, :content_type => 'text/plain'

     end 
end

尝试

# result will contain the response
result = RestClient.post('http://www.postful.com/service/mail', 
                    request.body,
                    {:content_type => 'text/plain',
                     'Authorization: Basic' => 'QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
p result.body
p result.code
p result.headers
