php - .htaccess URL 重写失败 - 在此服务器上找不到请求的 URL

Question

Apache/PHP 新手问题:

我正在尝试让 http://yourls.org/ 安装正常工作。

一切似乎都已安装好，我可以添加新的 url 并缩短它们。

但是链接生成了 404。 http://mydoma.in/4 应该重定向但没有

.htaccess 文件如下所示:

# BEGIN YOURLS
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /yourls-loader.php [L]
</IfModule>
# END YOURLS

如果我浏览到页面 http://mydoma.in/yourls-loader.php，它会将我重定向到主页。

我猜需要有一个 ID 参数需要通过重写传递给 /yourls-loader.php

/yourls-loader.php 看起来像这样:

<?php
// Handle inexistent root favicon requests and exit
if ( '/favicon.ico' == $_SERVER['REQUEST_URI'] ) {
    header( 'Content-Type: image/gif' );
    echo base64_decode( "R0lGODlhEAAQAJECAAAAzFZWzP///wAAACH5BAEAAAIALAAAAAAQABAAAAIplI+py+0PUQAgSGoNQFt0LWTVOE6GuX1H6onTVHaW2tEHnJ1YxPc+UwAAOw==" );
    exit;
}

// Handle inexistent root robots.txt requests and exit
if ( '/robots.txt' == $_SERVER['REQUEST_URI'] ) {
    header( 'Content-Type: text/plain; charset=utf-8' );
    echo "User-agent: *\n";
    echo "Disallow:\n";
    exit;
}

// Start YOURLS
require_once( dirname( __FILE__ ) . '/includes/load-yourls.php' );

// Get request in YOURLS base (eg in 'http://site.dom/yourls/abcd' get 'abdc')
$request = yourls_get_request();

// Make valid regexp pattern from authorized charset in keywords
$pattern = yourls_make_regexp_pattern( yourls_get_shorturl_charset() );

// Now load required template and exit

yourls_do_action( 'pre_load_template', $request );

// At this point, $request is not sanitized. Sanitize in loaded template.

// Redirection:
if( preg_match( "@^([$pattern]+)/?$@", $request, $matches ) ) {
    $keyword = isset( $matches[1] ) ? $matches[1] : '';
    $keyword = yourls_sanitize_keyword( $keyword );
    yourls_do_action( 'load_template_go', $keyword );
    require_once( YOURLS_ABSPATH.'/yourls-go.php' );
    exit;
}

// Stats:
if( preg_match( "@^([$pattern]+)\+(all)?/?$@", $request, $matches ) ) {
    $keyword = isset( $matches[1] ) ? $matches[1] : '';
    $keyword = yourls_sanitize_keyword( $keyword );
    $aggregate = isset( $matches[2] ) ? (bool)$matches[2] && yourls_allow_duplicate_longurls() : false;
    yourls_do_action( 'load_template_infos', $keyword );
    require_once( YOURLS_ABSPATH.'/yourls-infos.php' );
    exit;
}

// Prefix-n-Shorten sends to bookmarklet (doesn't work on Windows)
if( preg_match( "@^[a-zA-Z]+://.+@", $request, $matches ) ) {
    $url = yourls_sanitize_url( $matches[0] );
    if( $parse = yourls_get_protocol_slashes_and_rest( $url, array( 'up', 'us', 'ur' ) ) ) {
        yourls_do_action( 'load_template_redirect_admin', $url );
        $parse = array_map( 'rawurlencode', $parse );
        // Redirect to /admin/index.php?up=<url protocol>&us=<url slashes>&ur=<url rest>
        yourls_redirect( yourls_add_query_arg( $parse , yourls_admin_url( 'index.php' ) ), 302 );
        exit;
    }
}

// Past this point this is a request the loader could not understand
yourls_do_action( 'loader_failed', $request );
yourls_redirect( YOURLS_SITE, 302 );
exit;

yourls_get_request() 函数如下所示:

function yourls_get_request() {
    // Allow plugins to short-circuit the whole function
    $pre = yourls_apply_filter( 'shunt_get_request', false );
    if ( false !== $pre )
        return $pre;

    static $request = null;

    yourls_do_action( 'pre_get_request', $request );

    if( $request !== null )
        return $request;

    // Ignore protocol & www. prefix
    $root = str_replace( array( 'https://', 'http://', 'https://www.', 'http://www.' ), '', YOURLS_SITE );
    // Case insensitive comparison of the YOURLS root to match both http://Sho.rt/blah and http://sho.rt/blah
    $request = preg_replace( "!$root/!i", '', $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'], 1 );

    // Unless request looks like a full URL (ie request is a simple keyword) strip query string
    if( !preg_match( "@^[a-zA-Z]+://.+@", $request ) ) {
        $request = current( explode( '?', $request ) );
    }

    return yourls_apply_filter( 'get_request', $request );
}

为了使用 mod_rewrite，您可以在终端中键入以下命令:(假设您使用的是基于 debian 的服务器)

$sudo a2enmod rewrite

之后重启apache2

$sudo /etc/init.d/apache2 restart

或

$sudo service apache2 restart

然后使用你的.htaccess

# BEGIN YOURLS
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ /yourls-loader.php [L]
</IfModule>
# END YOURLS
