如何在字符之间获取字符串（多字）

Question

您好，我正在尝试在两个括号之间获取字符串

str = "Reason = Failed to connect ( Nickname: Mc Gee ), Banned by: Andrew"

我只想得到昵称：Mc Gee

我到处找，但我看到的所有答案都是针对单字字符串的，不适用于 ()

Answer 1

您可以使用允许指定要匹配的括号的%b模式：

str = "Reason = Failed to connect ( Nickname: Mc Gee ), Banned by: Andrew"
print(str:match("%b()"):gsub("[()]","")) -- prints ` Nickname: Mc Gee `
