以下几行是我需要在lua中使用的任意正则表达式。有没有办法在lua(raw)中定义自动转义的字符串?
['\";=]
!^(?:(?:[a-z]{3,10}\s+(?:\w{3,7}?://[\w\-\./]*(?::\d+)?)?/[^?#]*(?:\?[^#\s]*)?(?:#[\S]*)?|connect (?:\d{1,3}\.){3}\d{1,3}\.?(?::\d+)?|options \*)\s+[\w\./]+|get /[^?#]*(?:\?[^#\s]*)?(?:#[\S]*)?)$

而且有很多人在那里,这些来自..... 点,你可能会注意到,第一种情况下只有"
是逃脱\"
机器人不是'
因此,
rex_pcre.new('['\";=]')
不起作用。
rex_pcre.new("['\";=]")
应该工作,但是,在正则表达式的部分,如\-
。
我也不能使用
[[ ]]
因为有正则表达式与]
(第一个例子)结束 破线在
rex_pcre.new([[
['\";=]
]])
会为我的情况下,如不能正常工作第三个以)
结尾,并且还引发了意外符号的错误。
r"UNESCAPED STRING"
或C#的
@"UNESCAPED STRING"
..
我认为没有这样的,但不知道什么是得到一个类似的功能的方式,鉴于,我只消耗这些值(正则表达式),并就如何撰写原来他们无法控制..
这是我目前的解决方案 我只是尝试编译线,用[[ ]]
,如果失败了,搬到"
和然后到“'”/
EscapeRegEx = function (xp)
-- try with [[ ]]
local opening = '[['
local closing = ']]'
local codeline = "rex_pcre.new(" .. opening .. xp .. closing .. ")"
_, err = loadstring(codeline)
if not err then return codeline end
-- then try with "
opening = '"'
closing = '"'
codeline = "rex_pcre.new(" .. opening .. xp .. closing .. ")"
_, err = loadstring(codeline)
if not err then return codeline end
-- then try with '
opening = "'"
closing = "'"
codeline = "rex_pcre.new(" .. opening .. xp .. closing .. ")"
_, err = loadstring(codeline)
if not err then return codeline end
end
做了工作!没有意识到这[=== [游戏。 –
