如何从Ruby发出HTTP POST请求

Question

我之前从未在Ruby中做过POST，而且我错过了一些简单的东西。

我正在尝试提出此请求：

curl -s -X POST "http://example.com:8280/purest/chatbot/actions/message" --data "message=hello there&rooms=myroom"

我有：

    url = "http://example.com:8280"
    uri = URI.parse(url)

    http = Net::HTTP.new(uri.host, uri.port)
    http.set_debug_output($stdout)

    request = Net::HTTP::Post.new("/purest/chatbot/actions/message")
    request.body = "message=hey from me in ruby&rooms=myroom"

    response = http.request(request)

这是输出：

<- "POST /purest/chatbot/actions/message HTTP/1.1\r\nAccept-Encoding: gzip;q=1.0,deflate;q=0.6,identity;q=0.3\r\nAccept: */*\r\nUser-Agent: Ruby\r\nConnection: close\r\nHost: example.com:8280\r\nContent-Length: 60\r\n\r\n"

有人能帮助我吗？
