.htaccess regex rewrite rule

问题

I have the following regex:

RewriteRule ^blogs/([^/]*)/([^/]*) blogs/index.php?blogger=$1&blog=$2

This works fine for the following cases:

• http://myurl.com/blogs/blog-name/blog-article/
• http://myurl.com/blogs/blog-name/blog-article
• http://myurl.com/blogs/blog-name/

however it does not handle:

• http://myurl.com/blogs/blog-name

How can I make the "/" separator optional in this regex?

回答1:

I'd use:

^blogs/([^/]*)(/([^/]*))?

And you'd just have to check and make sure that $2 is still correct (with the two capture groups, it might be $3… I can't remember).

回答2:

If the '?' is causing troubles then try:

^blogs/([^/]*)(/([^/]*)){0,1}
