我有一个小的 ruby 函数来返回查询结果。我想检查我服务器上的环境变量,所以我写了这个函数。但它没有像我预期的那样根据 puts 输出和代码返回 @result 。我究竟做错了什么?
def query(params=nil)
@result = {}
count = 1
ENV.each do |k,v|
@result[count.to_s] = { "name" => k, "company" => v }
puts "[#{count.to_s}] = { 'name' => #{k}, 'company' => #{v} }"
count += 1
end
end
输出:
irb(main):070:0> query
[1] = { 'name' => ALLUSERSPROFILE, 'company' => C:\ProgramData }
[2] = { 'name' => APPDATA, 'company' => C:\Users\xxxx\AppData\Roaming }
[3] = { 'name' => CLIENTNAME, 'company' => xxxx }
[4] = { 'name' => COLUMNS, 'company' => 160 }
[5] = { 'name' => CommonProgramFiles, 'company' => C:\Program Files (x86)\Common Files }
[6] = { 'name' => CommonProgramFiles(x86), 'company' => C:\Program Files (x86)\Common Files }
[7] = { 'name' => CommonProgramW6432, 'company' => C:\Program Files\Common Files }
....
@结果
irb(main):075:0> @result
=> {"ALLUSERSPROFILE"=>"C:\\ProgramData", "APPDATA"=>"C:\\Users\\xxxx\\AppData\\Roaming", "CLIENTNAME"=>"wxxxx", "COLUMNS"=>"160", "CommonProgramFiles"=>"C:
