如何处理.htaccess规则中的＆和/等特殊字符？

Question

In my .htaccess file I have defined following rule,

RewriteRule ^([-0-9a-zA-Z]+) search.php?id=$1

The above rule works fine if I am browsing http://example.com/abcd I need to use the symbols & % - / in the url like: http://example.com/ab&cd

What changes have to be made to the rule for this to work?

Answer 1

No idea how that rule is working for you. First, it loops. Second, there is no capture groups for $2 and $3 , but it doesn't matter because $1 is always "search" anyways. I'm assuming you've pasted a partial snippet of a rule that you have that works.

The reason why & , % , or / isn't being matched is because your regex says:

[-0-9a-zA-Z]+

which means: one or more letters, numbers, or a dash . So no & , % , or / . So you can add those into the square brackets:

RewriteRule ^([-0-9a-zA-Z/%&]+) search.php?id=$1&ff=$2&ffid=$3

However, keep in mind that the URI is decoded before any rules get applied. This means if the URI looks like:

/foo%28bar

You don't need to match against % , because the URI gets decoded into:

/foo(bar

and you need to match against ( . A better option may to just match against every except dots:

RewriteRule ^([^.]+) search.php?id=$1&ff=$2&ffid=$3

or whatever you don't want in your match.

Try:

RewriteRule ^([^.]+)$ search.php?id=$1 [B]

The difference here is the $ to bound the match to the end of the URI, and the B flag ensures the & gets encoded.

Answer 2

You need to URL encode 'ab&cd' using urlencode so that & gets turned into %26 .

After this, in search.php you'll need to account for it and decode it, using urldecode .

Answer 3

Do the URL like this:

http://example.com/id/ff/ffid

and write your rule around that. Also, why do you need 3 ID parameters? Couldn't you just lookup the other 2 using the first one?
