如何通过 Sinatra Ruby 应用程序处理 POSTed XML

发布于 2024-08-11 01:58:35 字数 818 浏览 1 评论 0原文

我计划将 Sinatra 用于一个新的小型网络服务 (WS)，我需要为客户组装该服务。

WS 只有两种方法，一种通过 GET 访问，一种通过 POST 访问。对于 POST 方法，客户端将向 sinatra WS 发送一个 XML 数据包，后者将解析数据并发出 200 OK HTTP 响应或 40x 错误代码。

我的问题是如何在 Sinatra 中解析传入的 POSTed XML 数据包？

下面是传入数据包的示例：

<?xml version="1.0" encoding="utf-8" ?>
<Counts>
  <OccupiedCount>300</OccupiedCount>
  <ReservedCount>40</ReservedCount>
  <VacantCount>160</VacantCount>
  <TotalCount>500</TotalCount>
  <Checksum>0777d5c17d4066b82ab86dff8a46af6f</Checksum>
  <Timestamp>2009-11-21T14:06:19Z</Timestamp>
  <ApiKey>1234567890qwerty</ApiKey>
</Counts>

是否有某种方法可以通过 Sinatra params 对象访问数据包，以便我可以使用 Crack XML 之类的内容来解析它？或者我是否需要使用某种 Rack 变量来获取发布到我的 WS 的整个 XML 数据包？

I'm planning on using Sinatra for a new tiny webservice (WS) that I need to put together for a client.

The WS will only have two methods, one accessed via GET and one via POST. For the POST method, the client will send an XML packet to the sinatra WS which will parse the data and issue either a 200 OK HTTP response or a 40x error code.

My question is how do I parse the incoming POSTed XML packet in Sinatra?

Here is an example of what the incoming data packet will look like:

<?xml version="1.0" encoding="utf-8" ?>
<Counts>
  <OccupiedCount>300</OccupiedCount>
  <ReservedCount>40</ReservedCount>
  <VacantCount>160</VacantCount>
  <TotalCount>500</TotalCount>
  <Checksum>0777d5c17d4066b82ab86dff8a46af6f</Checksum>
  <Timestamp>2009-11-21T14:06:19Z</Timestamp>
  <ApiKey>1234567890qwerty</ApiKey>
</Counts>

Is there someway to access the data packet via the Sinatra params object so that I can parse it with something like Crack XML? Or do I need to use some kind of Rack variable to get at the whole XML data packet that was POSTed to my WS?

sinatra app

require 'rubygems'
require 'sinatra'

post '/form' do
    puts params[:xml]
end

使用您的数据发布请求：

curl -d "xml=<?xml version="1.0" encoding="utf-8" ?>
<Counts>
  <OccupiedCount>300</OccupiedCount>
  <ReservedCount>40</ReservedCount>
  <VacantCount>160</VacantCount>
  <TotalCount>500</TotalCount>
  <Checksum>0777d5c17d4066b82ab86dff8a46af6f</Checksum>
  <Timestamp>2009-11-21T14:06:19Z</Timestamp>
  <ApiKey>1234567890qwerty</ApiKey>
</Counts>
" http://localhost:4567/form

结果：

- - [11/Nov/2009:12:05:40 PST] "POST /form HTTP/1.1" 200 0
- -> /form
<?xml version=1.0 encoding=utf-8 ?>
<Counts>
  <OccupiedCount>300</OccupiedCount>
  <ReservedCount>40</ReservedCount>
  <VacantCount>160</VacantCount>
  <TotalCount>500</TotalCount>
  <Checksum>0777d5c17d4066b82ab86dff8a46af6f</Checksum>
  <Timestamp>2009-11-21T14:06:19Z</Timestamp>
  <ApiKey>1234567890qwerty</ApiKey>
</Counts>

sinatra app

require 'rubygems'
require 'sinatra'

post '/form' do
    puts params[:xml]
end

Posting a request using your data:

curl -d "xml=<?xml version="1.0" encoding="utf-8" ?>
<Counts>
  <OccupiedCount>300</OccupiedCount>
  <ReservedCount>40</ReservedCount>
  <VacantCount>160</VacantCount>
  <TotalCount>500</TotalCount>
  <Checksum>0777d5c17d4066b82ab86dff8a46af6f</Checksum>
  <Timestamp>2009-11-21T14:06:19Z</Timestamp>
  <ApiKey>1234567890qwerty</ApiKey>
</Counts>
" http://localhost:4567/form

Result:

- - [11/Nov/2009:12:05:40 PST] "POST /form HTTP/1.1" 200 0
- -> /form
<?xml version=1.0 encoding=utf-8 ?>
<Counts>
  <OccupiedCount>300</OccupiedCount>
  <ReservedCount>40</ReservedCount>
  <VacantCount>160</VacantCount>
  <TotalCount>500</TotalCount>
  <Checksum>0777d5c17d4066b82ab86dff8a46af6f</Checksum>
