解析 JSON 输出时输出 Space

Question

我从以下 curl 命令的 JSON 输出中解析了值（感谢 Whosebug），

1.) 但我在输出中看到很好的 spaces（附上示例图像以供参考）。需要输出没有额外的spaces（在输出末尾看到额外的spaces，请参考图片）。请帮助解决这个问题，

（ruby 很新，很抱歉基础知识）

space after last line of output

2.)每个值后还需要space .

样本输出：

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

Answer 1

您在 map 迭代器中执行输出，然后执行额外的 puts。这不是必需的，如您所见，会导致不必要的输出。

将 map 替换为 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
