nginx rewrite of url with query string

Question

I have been googling for a good while and can't figure this one out. It seems simple, and I am sure it is, but I am not a server expert.

My url is: http://www.example.com/blog/?tag=Word1+Word2

Some of the tags are a single word (ex: bicycle), some are longer (ex: Two wheel bicycle).

I need this url to be output as: example.com/blog/tag/word1-word2/

How can I get a rewrite to achieve this?

I had looked at that one. The question I come back to is that /blog/ is the root of my blog. Those responses in that other post all have /location/file.asmx. I need the blog to work, and post urls like /blog/post-title/. — TJ Sherrill, Dec 18 '15 at 17:54

You should send - in your query instead of + to get same format and make an easier request :

location ~ /blog/ {
    if ($args ~* "tag=(.*)") {
        set $w1 $1;
        rewrite .* /blog/tag/$w1/? permanent;
    }
}

Based on the link i posted

? at the end will remove the query string parameters (from rewrite doc )

If you specify a ? at the end of a rewrite then Nginx will drop the original $args (arguments)

another to achieve it is to set args to nothing:

set $args '';

I tried variations on that and got 404's. what happens if the tag is only a single word like "bicycle"? – TJ Sherrill Dec 18 '15 at 18:28
in this case it will not works, so try first with 2 words, if it work i will modify to works for your case. Are there max 2 words, or can it be (n) words ? – Froggiz Dec 18 '15 at 18:42
it can be (n) words. It did not work when I tested on a two word tag. The rewrite you have there resulted in this url: http://www.urlt.com/blog/tag/-/?tag=Reliance+Nitro – TJ Sherrill Dec 18 '15 at 18:48
ok i did some change can you confirm it works now with 2 parameters ? – Froggiz Dec 18 '15 at 18:55
that resulted in: http://www.url.com/blog/tag/-/ – TJ Sherrill Dec 18 '15 at 18:58
