htaccess重写url并检查404

标签: php .htaccess mod-rewrite redirect url-rewriting

我有一家网店,想用htaccess来缩短链接 有3个网址:

shop.com/shop/18 (number) - products.php?categoryid=$1
shop.com/shop/18/page-2 (number)/(page+number) - products.php?categoryid=$1&page=$2
shop.com/shop/18/9877 (number)/(number) - description?categoryid=$1&productid=$2

我的尝试

RewriteRule ^shop/?$                        shop.php
RewriteRule ^shop/(.*)/([0-9]+)/?$          description.php?categoryid=$1&productid=$2
RewriteRule ^shop/(.*)/page-(.*)/?$         products.php?categoryid=$1&page=$2
RewriteRule ^shop/(.*)/?$                   products.php?categoryid=$1

我的尝试 - 1(工作),2(工作),3(不工作)

  1. 如何重写网址?

  2. 如果例如,我如何重定向到404页面?没有这样的数量     类别或此类产品(猜猜用php和mysql然后再检查     重定向)?

有很多方法可以解决这个问题;

  • 全部在htaccess中(多个深度变得混乱)
  • 组合htaccess和服务器端代码

最好的方法是根据您的商店编码方式适合您的方法。我个人认为在服务器端代码处理它更好,它简化了htaccess文件,并为您提供了更多的控制,以验证数据,以及如何处理发送的内容,处理内容以及处理时的处理方式

例如,在我的htaccess文件中,我有;

<IfModule mod_rewrite.c>
Options +FollowSymlinks
RewriteEngine on
#
# Do not apply rewrite rules for non required areas 
RewriteCond %{REQUEST_URI} "/hidden-areas/" [OR]
RewriteCond %{REQUEST_URI} "/other-areas/"
RewriteRule (.*) $1 [L]

# Do Not apply if a specific file or folder exists
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# The rules on how to rewrite the urls  
RewriteRule (.*) /index.php?url=$1 [QSA,L]
</IfModule>

基本上,简而言之,我不会为某些文件夹重写任何内容,我会直接转发它们。这是为了在外部停止对脚本的调用,或者可以毫无问题地访问额外添加的系统。

然后,我将整个url作为字符串转发到我的索引页面,并处理使用PHP的内容,下面是一个示例。

// collect the passed url
$url = $_GET['url'];
// split the url into parts
$url_parts = explode('/', $url);
/*
* start sorting what is what in the url
*/
// count how many parts there are
$url_parts_count = count($url_parts);
// determine the class/module
$class = $url_parts[0]; // generally the class/method/module depending on your system, thgough could be a category so run some checks
// determine the last part in the array
$last_url_part = ($url_parts_count - 1);
// set the last part of the url to be used
$slug = $url_parts[$last_url_part]; // generally the slug and will be empty if theres a trailing slash
etc etc etc

这只是一个总结,我做得更多,因为这是从我写的CMS中获取的,但是如果你想弄清楚它应该给你一个非常好的起点。当然,如果有必要,我很乐意进一步阐述。

当然,需要注意的是,如果您使用现成的系统,他们应该已经为您提供此代码;)

我根据您更新的问题添加了以下内容,如果您仍然计划按照自己的方式行事,这将有所帮助:)

<IfModule mod_rewrite.c>
  Options +FollowSymlinks
  RewriteEngine on
  RewriteBase /
  #
  # Do not apply rewrite rules for non required areas 
    RewriteCond %{REQUEST_URI} "/hidden-areas/" [OR]
    RewriteCond %{REQUEST_URI} "/other-areas/"
    RewriteRule (.*) $1 [L]

  # Do Not apply if a specific file or folder exists
  # RewriteCond %{REQUEST_FILENAME} !-f
  # RewriteCond %{REQUEST_FILENAME} !-d
  # The rules on how to rewrite the urls

  RewriteRule ^([a-zA-Z0-9_-]+)$ /index.php?slug=$1 [QSA,L]  
  RewriteRule ^([a-zA-Z0-9_-]+)/$ /index.php?type=$1 [QSA,L]  
  RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)$ /index.php?type=$1&slug=$2 [QSA,L]  
  RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/$ /index.php?type=$1&cat=$2 [QSA,L]
  RewriteRule ^([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)/([a-zA-Z0-9_-]+)$ /index.php?type=$1&cat=$2&slug=$3 [QSA,L] 
</IfModule>
