htaccess不断重新应用匹配的规则并最终循环

时间：2011-11-11 07:37:42

标签： apache .htaccess

根据http://htaccess.madewithlove.be/，以下规则集可以完美运行：

RewriteEngine On
  RewriteBase /

RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^images/([^\?]+)$ /_lib/mask_images.php [L]
  RewriteRule ^search/([^\?]+)/merchant/([^\?]+)/brand/([^\?]+)/page/([^\?]+)$ /search.php?keyword=$1&merchant=$2&brand=$3&page=$4 [L]
  RewriteRule ^search/([^\?]+)/brand/([^\?]+)/page/([^\?]+)$ /search.php?keyword=$1&brand=$2&page=$3 [L]
  RewriteRule ^search/([^\?]+)/merchant/([^\?]+)/page/([^\?]+)$ /search.php?keyword=$1&merchant=$2&page=$3 [L]
  RewriteRule ^search/([^\?]+)/page/([^\?]+)$ /search.php?keyword=$1&page=$2 [L]
  RewriteRule ^search/([^\?]+)/brand/([^\?]+)$ /search.php?keyword=$1&brand=$2 [L]
  RewriteRule ^search/([^\?]+)/merchant/([^\?]+)$ /search.php?keyword=$1&merchant=$2 [L]
  RewriteRule ^search/([^\?]+)/merchant/([^\?]+)/brand/([^\?]+)$ /search.php?keyword=$1&merchant=$2&brand=$3 [L]
  RewriteRule ^search/([^\?]+)$ /search.php?keyword=$1 [L]
  RewriteRule ([^\?]+)/productID/([^\?]+)$ /detail.php?keyword=$1&productID=$2 [L]
  RewriteRule ([^\?]+)$ /detail.php?keyword=$1 [L]

问题在于，当应用并匹配最后两个规则时，Apache会重新应用匹配的规则（以及正确分配的参数）并进入无限循环。

我补充说：

  RewriteCond %{REQUEST_URI} !search.php$
  RewriteCond %{REQUEST_URI} !detail.php$
  RewriteCond %{REQUEST_URI} !index.php$

到上面的规则集。再次，经过htaccess测试人员网站的验证和工作，它现在停止处理并输出“detail.php”作为参数。

正如您所看到的，它匹配正确的规则并且参数设置正确，但由于某种原因，它再次重新应用该内部重定向，并且参数将从应该更改（在此示例中）是“hello”）文件名，detail.php

不知道如何解决这个问题，因为我目前所知道的一切，这应该是有效的，因为/搜索工作非常出色。

修改

这是detail.php包含的内容：

<?
echo $_GET["keyword"]."<br>";
echo $_GET["merchant"]."<br>";
echo $_GET["brand"]."<br>";
echo $_GET["page"]."<br>";
echo $_GET["productID"]."<br>";
exit();
?>

2 个答案:

答案 0 :(得分：0)

/detail.php的最终[L]执行（内部）重定向。因此Apache看到了一个全新的请求 - 重新应用规则。

所以选项可能是为了确保规则不适用于/detail.php（即通过确保参数名称有点不同）或者提前预防^ / detail.php并否定。< / p>

http://www.sitepoint.com/mod_rewrite-no-endless-loops/试图用不同的词语来解释这一点。另一种常见方法是使用以下内容：

# Loop stopping snippets.

# Uncomment if there are specific pages to exempt.
# RewriteCond %{REQUEST_URI} ^/(stats/|missing\.html|failed_auth\.html|error/).* [NC]
# RewriteRule .* - [L]

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule .* - [L]

你在第二遍（在内部重定向之后）检测到这一点并在早期以通用方式保释。

DW传递。

答案 1 :(得分：0)

您的缩进不反映RewriteRule和RewriteCond指令的语义关联。

条件

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

仅在URI模式为^ images /（[^ \？] +）$时才适用。你需要的是逻辑上翻转这个或者至少跳过以下10条规则来申请所有 URI模式：

RewriteCond %{REQUEST_FILENAME} -f        [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule .                   -         [SKIP=10]
