regex 删除查询字符串并匹配 url 中的剩余部分 [英] regex to remove the querystring and match the remaining segments from the url
问题描述
npinti 帮助我创建了一个正则表达式来删除查询字符串并匹配 url /seattle 中的剩余部分/restaurant/sushi?page=2:像这样应该产生 3 个组:/(.*?)/(restaurant)/([^?]+).*.第 1 组是座位，第 2 组是餐厅，第 3 组是寿司.如果在最后一个/之后有一个 ?，正则表达式会丢弃 ? 以及后面的所有内容."
npinti helped me create a regex to remove the querystring and match the remaining segments from the url /seattle/restaurant/sushi?page=2: "Something like so should yield 3 groups: /(.*?)/(restaurant)/([^?]+).*. Group 1 being seatthe, group 2 being restaurant and group 3 being sushi. If after the last /there is a ?, the regex discards the ? and everything which follows."
我尝试修改上面的内容以在 url /seattle/restaurant?page=2 上执行相同的技巧，但我无法做到.不知道会不会有af querystring或者querystring的参数.所以我需要上面正则表达式的灵活性，它会匹配并丢弃 ?以及接下来的一切.
I have tried modifying the above to do the same trick on the url /seattle/restaurant?page=2 but I could not get it right. I don't know if there will be af querystring or not or the parameters of the querystring. So I need the flexibility from the regex above which will match and discard the ? and everything which follows.
推荐答案
您的重写规则可能如下所示:
Your rewriterules may look like:
RewriteRule /([^/]+)/restaurant/([^/]+)$ mynewpage.php?group1=$1&group2=$2 [QSA,NC,L]
感谢我在下面提供的链接，您可以搜索QSA、NC 和L 的含义.

很抱歉，您的问题听起来很像我不是很好，所以有人可以帮我完成这项工作吗?".我的意思是，环顾四周，你会得到很多答案，只要把手弄脏.
I'm sorry but your question sound very like "I'm not very good, so can someone do the job for me?". I mean, just look around, you'll get a lot of answer, just get your hands dirty.
如果这还不够:
如果您不是在托管环境中(=如果它是您自己的服务器并且您可以修改虚拟主机，不仅是 .htaccess 文件)，尝试使用 RewriteLog 指令:它可以帮助您追踪此类问题:
If you're not in a hosted environment (= if it's your own server and you can modify the virtual hosts, not only the .htaccess files), try to use the RewriteLog directive: it helps you to track down such problems:
# Trace:
# (!) file gets big quickly, remove in prod environments:
RewriteLog "/web/logs/mywebsite.rewrite.log"
RewriteLogLevel 9
RewriteEngine On
