我有一个脚本,当在控制台中运行时,它会执行一系列 api 调用,并且效果很好。但是当我在服务器上运行它时,我得到一个“getaddrinfo:发生不可恢复的错误..”错误

这是我的一段似乎导致问题的代码:

require "uri"
require "net/http"
require "json"
uri = URI("https://api.domain.com/location/of/api_call/data.json?other=1&query=1&stuff=1")
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
headers = {"Range" => "bytes=1000-",
           "Api-Key" => API_KEY,
           "X-Api-Secret" => API_SECRET}
response = ""
res = http.get(uri.path + "?" + uri.query, headers) do |data|
    response += data
end
if res.code.to_i === 200
    response = JSON.parse(response)
else
    response = {"error" => "api call failed"}
end

相当简单......我不得不稍微按摩一下 http 和 res 对象以获得所需的结果。它在控制台上运行良好,但是当我启动服务器时出现错误。

上下文:我正在运行一个 Dashing 仪表板,它使用 rufus-scheduler 来安排作业。这是我计划每 30 分钟运行一次的工作。Dashing 还使用瘦服务器而不是 Unicorn。

这是我得到的完整错误:

scheduler caught exception:
getaddrinfo: A non-recoverable error occurred during a database lookup.

c:/path/to/file.rb: 215:in `block in <top (required)>'

注意:第 215 行在“res = ...”上

更新:

我对 api 地址进行了 nslookup 并得到了

*** Default servers are not available
Server:  UnKnown
Address:  127.0.0.1
