.htaccess code to protect a single URL?

问题:

Is it possible to protect a single URL through .htaccess? For example I will have website.com/index.php?skin=name. Can I password protect only this url? (with no PHP changes, only .htaccess)

website.com/index.php or website.com/index.php?skin=other_name should not be restricted.

回答1:

You can rewrite the address to protect it like this:

RewriteEngine On
RewriteCond %{REQUEST_URI}  ^/index\.php$
RewriteCond %{QUERY_STRING} ^skin=(name)$
RewriteRule ^(.*)$ /skin/%1 [PT]

<LocationMatch "/skin/name">
     AuthType Basic
     AuthName "By Invitation Only"
     AuthUserFile /path/to/passwords
     Require valid-user
</LocationMatch>

回答2:

You can if you use mod-rewrite to rewrite the address to something else and protect that.

You can't use LocationMatch, even though it would appear that you could.

Your best bet is to do it in PHP. A quick google search later and I found a great way to use PHP_AUTH which looks a lot like the .HTACCESS login prompt

<?php
$login_successful = false;

// check user & pwd:
if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW'])){

    $usr = $_SERVER['PHP_AUTH_USER'];
    $pwd = $_SERVER['PHP_AUTH_PW'];

    if ($usr == 'jonas' && $pwd == 'secret'){
        $login_successful = true;
    }
}

// login ok?
if (!$login_successful){

    // send 401 headers:
    // realm="something" will be shown in the login box 
    header('WWW-Authenticate: Basic realm="Secret page"');
    header('HTTP/1.0 401 Unauthorized');
    print "Login failed!\n";

}
else {
    // show secret page:
    print 'you reached the secret page!';
}
