通过终端运行ruby中的net/http时出错

Question

在ruby中运行Net::HTTP post请求。我正在使用Ubuntu中的终端，并收到以下错误消息：

SocketError: getaddrinfo: Name or service not known
from /usr/lib/ruby/1.9.1/net/http.rb:762:in `initialize'
from /usr/lib/ruby/1.9.1/net/http.rb:762:in `open'

from /usr/lib/ruby/1.9.1/net/http.rb:1096:in `post'
from (irb):356
from /usr/bin/irb:12:in `<main>'

运行以下代码：

uri = @@url
http = Net::HTTP.new(uri)
response = http.post('/', @@str)
puts response

“名称或服务未知”是套接字级别的错误，当您无法解析给定的域名或指定无法连接到的IP地址时，将抛出此错误。如果不发布您正在尝试发布的URL和字符串，则没有其他信息可用。
