将String拆分为值数组
输入字符串： –
str = '"2014-09-04 21:12:05" 5469687123030383463 192.168.1.2 4 7879 0 43 "www.test.com/" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36" 404 123 F 21549 50 0 - Test1 当我用空格分开时： –
str.split(' ') => ["\"2014-09-04", "21:12:05\"", "5469687123030383463", "192.168.1.2", "4", "7879", "0", "43", "\"www.test.com/\"", "\"Mozilla/5.0", "(X11;", "Linux", "x86_64)", "AppleWebKit/537.36", "(KHTML,", "like", "Gecko)", "Chrome/35.0.1916.153", "Safari/537.36\"", "404", "123", "F", "21549", "50", "0", "-", "Test1"]
预期：-
str = ["2014-09-04 21:12:05", "5469687123030383463", "192.168.1.2", "4", "7879", "0", "43", "www.test.com/", "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36", "404", "123", "F", "21549", "50", "0", "-", "Test1"]
我怎样才能通过ruby实现
您的字符串看起来与UNIX shell参数非常相似，我只使用Shellwords :: shellsplit 。 请注意，这会删除引号，但您真的需要它们吗？
require 'shellwords' Shellwords::shellsplit(str) #=> ["2014-09-04 21:12:05", "5469687123030383463", ..., "-", "Test1"]
您可以在正则表达式中单独涵盖这两种情况，并使用|将它们连接起来 ：
str.scan(/"[^"]+"|[^ ]+/)
