Question

我正在尝试在数组中发送关键值的一些数据，但是难以接受。

这是我的数组中的内容：

data = [ "name=abc", "title=analyst", "group=IT", "id=123"]

我想要翻译的地图：

mapping = { "name" => "EmployeeName", "title" => "JobTitle", "group" => "BusinessGroup", "id" => "EmployeeID"}

我追求的预期结果：

data = [ "EmployeeName=abc", "JobTitle=analyst", "BusinessGroup=IT", "EmployeeID=123"]

Answer 1

data.map {|s| s.sub /\w+/, mapping }
# => ["EmployeeName=abc", "JobTitle=analyst", "BusinessGroup=IT", "EmployeeID=123"]

Answer 2

data.map { |str| str.split(/\s*=\s*/).tap { |k,_| k.replace(mapping[k]) }.join('=') }
  #=> ["EmployeeName=abc", "JobTitle=analyst", "BusinessGroup=IT",  "EmployeeID=123"]

如果/\s*=\s*/之前或之后有任何空格，我会在"="而不是=上拆分。

Answer 3

根据您的data数组和mapping哈希，您可以使用Array#map执行以下操作：

  data.map do |i|
    key, value = i.split('=')
    "#{mapping[key]}=#{value}"
  end
# => ["EmployeeName=abc", "JobTitle=analyst", "BusinessGroup=IT", # "EmployeeID=123"]

Answer 4

> data.map{|a| a.split("=")}.map{|e| mapping.has_key?(e[0]) ? "#{e[0] = mapping[e[0]]}=#{e[1]}" : "#{e[0]}\=#{e[1]}"}
 => ["EmployeeName=abc", "JobTitle=analyst", "BusinessGroup=IT", "EmployeeID=123"]
