ruby - 通过终端在 ruby​​ 中运行 net/http 时出错

Question

在 ruby​​ 中运行 Net::HTTP 发布请求。我在 Ubuntu 中使用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:762:in `block in connect'
from /usr/lib/ruby/1.9.1/timeout.rb:54:in `timeout'
from /usr/lib/ruby/1.9.1/timeout.rb:99:in `timeout'
from /usr/lib/ruby/1.9.1/net/http.rb:762:in `connect'

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”是当您无法解析给定域名或指定无法连接的 IP 地址时引发的套接字级别错误。如果不发布您尝试发布的 URL 和字符串，则没有其他信息可用。
