解析 JSON 输出时输出中的空格

卡蒂克拉吉

我从下面 curl 命令的 JSON 输出中解析值（感谢 stackoverflow），

1.) 但我在输出中看到很大的空格（附上示例图像以供参考）。需要没有多余空格的输出（在输出末尾看到多余的空格，请参考图片）。请对此提供帮助，

（对于基本的东西，ruby 很新表示歉意）

2.) 每个值后也需要空格。

样品输出：

卷曲：

def incidents

value = `curl https://api.statuspage.io/v1/pages/incidents.json -H "Authorization: OAuth a8ef"`

data_hash = JSON.parse(value).map {|h| puts "ID : #{h["id"]} , CREATED AT : #{h["created_at"]} , LINK : #{h["shortlink"]} , ISSUE NAME : #{h["name"]} , DESCRIPTION :  #{h["incident_updates"][1]["body"]} , STATUS : #{h["incident_updates"][1]["status"]} ,DESCRIPTION :  #{h["incident_updates"][0]["body"]} , STATUS : #{h["incident_updates"][0]["status"]}"}

puts data_hash


end

您在map迭代器中执行输出，然后执行附加puts. 这是没有必要的，正如您所看到的，会导致不必要的输出。

替换map为each并删除最后一个puts。类似的东西：

  JSON.parse(value).each do |h|
    puts "ID : #{h["id"]} , CREATED AT : #{h["created_at"]} , LINK : #{h["shortlink"]} , ISSUE NAME : #{h["name"]} , DESCRIPTION :  #{h["incident_updates"][1]["body"]} , STATUS : #{h["incident_updates"][1]["status"]} ,DESCRIPTION :  #{h["incident_updates"][0]["body"]} , STATUS : #{h["incident_updates"][0]["status"]}"
  end
