本文介绍了Scala - 大小写匹配部分字符串的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有以下几点:
serv match {
case "chat" => Chat_Server ! Relay_Message(serv)
case _ => null
}
问题是有时我还会在 serv 字符串的末尾传递一个额外的参数,所以:
The problem is that sometimes I also pass an additional param on the end of the serv string, so:
var serv = "chat.message"
有没有办法可以匹配字符串的一部分,这样它仍然会被发送到 Chat_Server?
Is there a way I can match a part of the string so it still gets sent to Chat_Server?
感谢您的帮助,非常感谢:)
Thanks for any help, much appreciated :)
推荐答案
使用正则表达式 ;)
Use regexes ;)
val Pattern = "(chat.*)".r
serv match {
case Pattern(chat) => "It's a chat"
case _ => "Something else"
}
使用正则表达式,您甚至可以轻松拆分参数和基本字符串:
And with regexes you can even easily split parameter and base string:
val Pattern = "(chat)(.*)".r
serv match {
case Pattern(chat,param) => "It's a %s with a %s".format(chat,param)
case _ => "Something else"
}
