重定向特定的网址变量

Question

My site used to generate URLs like this:

/data.php?s=1432862823&type=basic

I have modified the program so the new URLs generated are:

/d.php?s=1432862823&t=basic

Since some people have bookmarked the old URLs I want to write a Rewrite rule that will get them to the new url.

I've not this so far:

RewriteEngine  on
RewriteRule    "^/data\.php$"  "/d.php"

but I can't figure out how to account for the variables.

Answer 1

Try this :

RewriteEngine On
RewriteCond %{QUERY_STRING} ^s=([^&]+)&type=([^&]+) [NC] 
RewriteRule ^data.php$ /d.php?s=%1&t=%2 [NC,R,L]

This will externally redirect a request for :

/data.php?s=foo&type=bar 

to

/d.php?s=foo&t=bar

Answer 2

Edit: I do apologise, I only noticed now that you have changed the type parameter to t . As such, this solution will not fit your needs, unless for a URI where the query string parameters do not change. I'm leaving this answer here so that others may learn from it - you'll be surprised how many people don't know that the query string is automatically transferred to the new destination. Starkeen's answer, therefore, is the correct answer.

You could follow Starkeen's solution, which specifically checks for the query string and explicitly adds it to d.php . Alternatively, for simplicity, you could just use this:

RewriteEngine on   
RewriteRule ^data.php$ /d.php [R=302,L]

The query string will automatically be transferred from data.php to d.php , and you will be redirected accordingly.

To make the redirect permanent and cached by browsers and search engines, change 302 to 301 .
