使用Ruby将XML请求发布到Web服务器

我担心我在网络服务器上发布文档（例如XML）的经验不多，所以如果我对HTTP的理解不足，我会道歉。

I'm afraid I've not got much experience with posting documents (e.g. XML) over web-servers, so I apologise if my understanding of HTTP is lacking.

我在 127.0.0.1 port 2000 上的ruby应用程序中设置了一个基本的Mongrel Web服务器。 （服务器）。

I have a basic Mongrel web server set up in a ruby app on 127.0.0.1 port 2000. (The server).

我在同一台计算机上运行一个单独的Ruby应用程序。 （客户端）。

I am running a separate Ruby app on the same computer. (The client).

我需要客户端将XML文档发布到服务器。

I need the client to POST an XML document to the server.

我有尝试使用Net :: HTTP来做到这一点，但我找不到一个明确的例子告诉我应该做什么。
我已经去了，但遇到了错误。我已经打破了请求，使其尽可能基本：

I have tried using Net::HTTP to do this, but I can't find a clear example which tells me what I should do. I've had a go, but encountered errors. I have broken the request down to make it as basic as possible:

http = Net::HTTP.new("127.0.0.1", 2000)
http.post('file', 'query=foo') #xc.rb line 6

但会导致以下错误

我想我完全错了。请你给我一个例子（或指向我的教程），让我发布一些基本数据，比如< tag1> text< / tag1> 。希望我能够设计出适当的标题并处理响应。

I imagine I'm doing it totally wrong. Please can you give me an example (or point me to a tutorial) that should allow me to post some basic data, like "<tag1>text</tag1>". Hopefully, I will then be able to work out setting the appropriate headers and handling the response.

另外，我不需要使用net / http;任何没有额外商业使用许可限制的免费方法都可以。

Also, I don't need to use net/http; any free method that doesn't come with extra commercial-use licencing restrictions is fine.
