使用Ruby将XML请求发布到Web服务器

Question

我担心在Web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.

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

我在同一台计算机上运行一个单独的Ruby应用程序.(客户端).

我需要客户端将XML文档POST到服务器.

我曾尝试使用Net :: HTTP来做到这一点,但我找不到一个明确的例子,告诉我应该做些什么.我有一个去,但遇到了错误.我已经打破了请求,使其尽可能基本:

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

但它会导致以下错误

    C:/Ruby193/lib/ruby/1.9.1/net/protocol.rb:141:in `read_nonblock': An existing connection was forcibly closed by the remote host. (Errno::ECONNRESET)
    from C:/Ruby193/lib/ruby/1.9.1/net/protocol.rb:141:in `rbuf_fill'

    from C:/Ruby193/lib/ruby/1.9.1/net/http.rb:1316:in `transport_request'
    from C:/Ruby193/lib/ruby/1.9.1/net/http.rb:1293:in `request'
    from C:/Ruby193/lib/ruby/1.9.1/net/http.rb:1286:in `block in request'
    from C:/Ruby193/lib/ruby/1.9.1/net/http.rb:745:in `start'

    from C:/Ruby193/lib/ruby/1.9.1/net/http.rb:1096:in `post'
    from W:/Ruby/A/xc.rb:6:in `<main>'

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.

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.

当使用rest-client gem时，这非常简单

require 'rest-client'

response = RestClient.post "http://127.0.0.1:2000", "<tag1>text</tag1>", :content_type => "text/xml"
