如何將逗號分隔的字符串轉換爲數組？

Question

有什麼辦法在Ruby中將逗號分隔的字符串轉換爲數組？例如，如果我有這樣一個字符串：

"one,two,three,four" 

我該如何將它轉換成這樣的數組？如果你想忽略前/後空格使用

"one,two,three,four".split(',') 
# ["one","two","three","four"] 

：

"one , two , three , four".split(/\s*,\s*/) 
# ["one", "two", "three", "four"] 

如果要分析多行（即

["one", "two", "three", "four"] 

Answer 1

使用split方法來做到這一點CSV文件）轉換爲獨立陣列：

require "csv" 
CSV.parse("one,two\nthree,four") 
# [["one","two"],["three","four"]] 

Answer 2

>> "one,two,three,four".split "," 
=> ["one", "two", "three", "four"] 

Answer 3

require 'csv' 
CSV.parse_line('one,two,three,four') #=> ["one", "two", "three", "four"]
