.htaccess mod_rewrite规则不起作用

Question

I'm trying to get mod-rewrite to work in a htaccess file.

The URL I'm trying to achieve is:

blog/{id}-{title}/

So for example:

http://localhost/blog.php?id=12&title=this-is-a-test

Would become:

http://localhost/blog/12-this-is-a-test/

No what I've been trying is:

RewriteEngine On
RewriteRule ^blog/([0-9]+)-([a-zA-Z-])/$ blog.php?id=$1&title=$2

When I go to http://localhost/blog/12-this-is-a-test/ I get a 404 error but if I go to http://localhost/blog.php the test page with the test text displays as expected.

Maybe I've written the rule incorrectly, if so can anyone suggest edits or are there any good tutorials, I've been reading through the http://httpd.apache.org/docs/2.0/misc/rewriteguide.html but haven't been able to figure out where I'm going wrong.

Any help is greatly appreciated or even pointing me in the right direction, thanks.

EDIT:

I was getting this on every link that the redirect rule applied:

http://localhost/C:/Apache/htdocs/test5/blog/1-Lorem-ipsum-dolor-sit-amet

After I added in the below to the vhost:

<Directory "{path}">
    Options All               
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

And I had to clear out the browser cache as it was also causing issues. Once these two actions where taken, anubhava's answer below worked and solved my issues.

Your regex is missing quantifier + which is causing 2nd capture group to fail since it is expecting only 1 character:

Options -MultiViews
RewriteEngine On
RewriteBase /

RewriteRule ^blog/([0-9]+)-([a-zA-Z-]+)/?$ blog.php?id=$1&title=$2 [L,NC,QSA]

Also better to turn off MultiViews since your php file name blog.php is same as directory name blog .
