Apache Rewrite匹配问号的写法

把 /abc?id=123  =>  /def.php?id=123 的写法：

RewriteEngine on
RewriteCond %{QUERY_STRING} ^id=(.+)$
RewriteRule ^/abc$ /def.php?sid=%1 [L]

RewriteRule 不会去匹配 ? 后面的字符串，需要用RewriteCond来匹配

RewriteEngine on
# Set the RewriteBase to "/" for the root level to base everything on... I guess.
RewriteBase /
RewriteRule ^oldpage.php(.+) newpage.php$1&otherid=0 [R]
-------------------------------------------------
The $1 should have all the variable stuff in it from the php.
So I'm looking for it to essentially do this:
oldpage.php?id=1 redirects to newpage.php?id=1&otherid=0
Why is this not working? Any help would be appreciated.

Because the RewriteRule directive doesn't parse anything beyond the path portion of the requested URL. If you want to capture the query string, you have to use a RewriteCond statement to store the query string in a regex back-reference. You can then make use of the RewriteCond's back-references in a succeeding RewriteRule statement. There's actually a shortcut for doing this (check the QSA flag in the mod_rewrite docs), but you need to modify the query string in the rewritten URL, so you can't use that.

Give this a try:


RewriteCond %{QUERY_STRING} ^(.+)$

RewriteRule ^oldpage.php newpage.php?otherid=0&%1 [R]

So I fiddled around and came up with this:



RewriteRule ^oldpage.php newpage.php?otherid=0 [QSA,R]



Why does this work? The only thing I can figure is that the query  

string is simply added to the end (as is says in the docs) of the new  

page. But I'm not even referencing the query string in the first  

part. Do I not need to do that? Does QSA take whatever the query

Hey,

mod_rewrite is the swiss army knife of web deployment, so how could this be

OT? ;-)



Firstly, you're missing a question mark in your rewrite rule, every request

will at least start with a SLASH (/) and then adding QSA to your rewrite

rule might help in passing over query strings.

(QSA = QeryStringAppend)



^ matches the begining of the requested URI which will always start with a

slash as in:

    http//www.apple.com/hardware

    ^ protocol

         ^ host

                       ^ requested URI including /

   

So give this a try:



RewriteRule ^/oldpage.php(.*) newpage.php?$1&otherid=0 [QSA,R]

             ^                           ^              ^^^

             this is needed              you missed this    this QSA is new



    or even

RewriteRule ^/oldpage.php(.*) newpage.php?$1&otherid=0 [QSA,R=301]

(R=301 makes the redirect a PERMANENT redirect)



I'd even go so far to add a Rewrite Condition, so the rule doesn't have to

be run for all requests:



RewriteCond %{REQUEST_URI} ^/.*\.php.* [NC]

RewriteRule ^oldpage.php(.*) newpage.php?$1&otherid=0 [QSA,R=301]



([NC] turns on case insensitivenes on the matches so .PHP=.php etc.)



Also to debug problems with ModRewrite, it realy helps turning logging on to

see what is actualy happening:



RewriteLog "/var/log/httpd/rewrite.log"

RewriteLogLevel 13
