问题
Want to rewrite an URL with a given user-prefix ("u-") from
https://example.com/access/check?user=u-abc&pass=123
to an URL without the prefix:
https://example.com/access/check?user=abc&pass=123
I tried several rules, e.g
RewriteBase /
RewriteRule ^access/check?user=u-(.*)$ check?user=$1
I am stuck with the "?"
IF the rewrite had to apply to slightly the same, but without the "?", it indeed works:
https://example.com/access/checkuser=u-abc&pass=123
RewriteRule ^access/checkuser=u-(.*)$ checkuser=$1
and provides the expected outcome (without the user-prefix "u-")
checkuser=abc&pass=123
I tried to match the "?" with [?] or \x3F, and applied the QSA flag as described on mod_rewrite.org , but still not succeeded.
回答1:
The query string is not part of the RewriteRule pattern
What is matched?
- ...
- If you wish to match against the hostname, port, or query string, use a RewriteCond with the %{HTTP_HOST}, %{SERVER_PORT}, or %{QUERY_STRING} variables respectively.
So in your case, you must check against QUERY_STRING and use the replacement %1 instead of $1
RewriteCond %{QUERY_STRING} user=u-(.*)
RewriteRule ^access/check$ /access/check?user=%1 [L]
回答2:
To match a "?" which is a query string, you need a RewriteCond, query strings can't be matched with a RewriteRule alone.
By definition a query string is everything after the "?", and you can use them in destination of a RewriteRule but to match them you will need a RewriteCond as I just mentioned.
Example:
RewriteCond %{QUERY_STRING} ^user=u-(.*)
RewriteRule ^access/check check?user=%1
Note captured groups from RewriteCond are referred to with the % symbol.
Play a bit with simple examples and try out.
回答3:
QueryString is not part of match in Rule's pattern, you need to match against %{QUERY_STRING} using RewriteCond
RewriteEngine on
RewriteCond %{QUERY_STRING} ^user=u-([^&]+)&pass=([^&]+)$
RewriteRule ^access/check/?$ /access/check/?user=%1&pass=%2 [L]
