Ruby 拆分和解析批处理的 HTTP 响应 (multipart/mixed)

Question

我正在使用 GMail API，它允许我获得多个 Gmail objects 的批处理响应。这以 multipart/mixed HTTP 响应的形式返回，其中一组单独的 HTTP 响应由 header 中定义的边界分隔。每个 HTTP sub-Responses 是一个 JSON 格式。

即

result.response.response_headers = {...
  "content-type"=>"multipart/mixed; boundary=batch_abcdefg"...
}

result.response.body = "----batch_abcdefg
<the response header>
{some JSON}
--batch_abcdefg
<another response header>
{some JSON}
--batch_abcdefg--"

是否有库或简单的方法将这些响应从字符串转换为一组单独的 HTTP 响应或 JSON objects？

感谢上面的Tholle...

def parse_batch_response(response, json=true)
  # Not the same delimiter in the response as we specify ourselves in the request,
  # so we have to extract it. 
  # This should give us exactly what we need.
  delimiter = response.split("\r\n")[0].strip
  parts = response.split(delimiter)
  # The first part will always be an empty string. Just remove it.
  parts.shift
  # The last part will be the "--". Just remove it.
  parts.pop

  if json  
    # collects the response body as json
    results = parts.map{ |part| JSON.parse(part.match(/{.+}/m).to_s)}
  else
    # collates the separate responses as strings so you can do something with them
    # e.g. you need the response codes
    results = parts.map{ |part| part}
  end
  result
end
