我们是从一个旧网站切换到新站点的搜索引擎优化更好的URL。 我试图做到这一点：
We're switching from an old site to a new site with better URLs for SEO. I'm trying to do this:
RewriteRule ^products/boots/materialid/(.*)/colour/(.*)$ http://www.mydomain.com/boots/$2/$1 [R=301,L]
但问题是：
1），而不是使用（。*），我可以指定这个可以有以下字符
1) Instead of using (.*), can I specify that this can have the following characters
A-ZA-Z0-9
在欧洲的任何字符，例如德国的特殊UTF8字符
_ 和 - 符号
也可以包含 + 符号（如黑+皮）
any alphanumeric character a-zA-Z0-9
any Euro character such as German special UTF8 characters
_ and - symbols
also can contain a + symbol (e.g. black+leather)
2）如果以上都不行，以及我对这个常识，如何更新上面，这样斜线是可选的？例如。对于上述规则，将
2) If the above won't work, and for my general knowledge on this, how do I update the above so that a trailing slash is optional? E.g. for the above rule, going to
www.mydomain.com/materialid/leather/colour/blue/
送我到
www.mydomain.com/blue//leather
额外的斜线来，因为在原来的网址蓝之后的斜线，但我需要排除这一点。
The extra slash comes because of the slash after "blue" in the original URL, but I need to exclude this.
推荐答案
试试这个：
RewriteRule ^products/boots/materialid/([^/]*)/colour/([^/]*)/?$ http://www.mydomain.com/boots/$2/$1 [R=301,L]
[^ /] 匹配任何字符不是斜线。 / 表示可选尾随斜线（注意，这是捕获括号外面，因此它不会被包括在重写URL）。
[^/] matches any character that is NOT a slash. /? means an optional trailing slash (note that it is outside of the capturing parentheses, so that it will not be included in the rewritten URL).
修改
根据您的评论，添加一个可选的index.php：
As per your comment, to add an optional /index.php:
RewriteRule ^products/boots/materialid/([^/]*)/colour/([^/]*)(/|/index.php)?$ http://www.mydomain.com/boots/$2/$1 [R=301,L]
