php - urlencode 问题

我在过滤系统中编码&符号时遇到问题。
例如,如果第一个过滤器用于品牌且品牌名称为“海飞丝”,则 url 应类似于 website/category/brand-head+%26+shoulders,但仅当 url 为 website/category/时过滤器才有效brand-head-%252526+shoulders.
如果选择了另一个过滤器,例如高度,如果 url 是 website/category/brand-head-%25252526+shoulders 等品牌过滤器有效,我必须在百分号前再添加 25。

这是品牌过滤代码

if($brand == false){
$data['brands'] = array();
$brands = $attributes->getBrands($av_list, $_GET['c']);
$brandTotalCnt = 0;

if(!empty($brands)){
foreach ($brands as &$brand) {
if($av_list){
$cur_av_list = $av_list . $brand['brand'];
$cur_av_uri = $_GET['av'] . $brand['brand'];
} else {
$cur_av_list = $brand['brand'];
$cur_av_uri = $brand['brand'];
}
$tmp_uri = explode('/', $ln_uri);
$tmp_uri_array = $attributes->remove_items_by_value($tmp_uri, 'brand');
$new_uri = implode('/', $tmp_uri_array);
$brandTotalCnt += $brand['num'];

$data['brands'][] = array(
'brand' => ucwords(strtolower($brand['brand'])),
'num' => $brand['num'],
'href' => $url->link('/c/'.$_GET['c'], '/brand-'. urlencode(strtolower($brand['brand'].'1')). $new_uri)
);

}
}
$data['brandTotalCnt'] = $brandTotalCnt;
}

每个过滤器的 URL 解码

if(isset($brand)){
$sql .= " AND brand = '".urldecode($brand)."'";
}

if(isset($gramaj)){
$height= $_GET['height'];
$sql .= " AND height= '".urldecode($height)."'";
}

这是来 self 的 htaccess

# rewrite /category/brand-mybrand/country-mycountry/offer-yes/new-yes
# to /index.php/brand-mybrand/country-mycountry/offer-yes/new-yes?c=category
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^c/([^/]+)/([^-]+.+)/?$ /index.php/$2?c=$1 [L,QSA]

# rewrite /index.php/brand-mybrand/country-mycountry/offer-yes/new-yes?c=category
# converts any /name-val/ to query parameter name=val in every rewrite
# stopping when there is no part left after /index.php
RewriteRule ^(index\.php)/([^-]+)-([^/]+)(/.*)?$ /$1$4?$2=$3 [L,QSA]

最佳答案

PHP 在启动期间填充 $_GET[] 时自动解析查询字符串和 URL 解码值。

生成 URL 时 urlencode() 值是正确的,但您不能 urldecode()$_GET[].

更新:

正如 Apache documentation 中所解释的那样:

mod_rewrite has to unescape URLs before mapping them, so backreferences are unescaped at the time they are applied

如果您的重写规则采用路径的一部分并将其放入查询字符串中,标志 [B] (转义反向引用)指示引擎使用未转义的 URL 来匹配规则。

您的问题有两种解决方案:

  1. (简单的解决方案):生成包含非字母数字字符的 URL;仅使用字母、数字和破折号 (-),您就安全了;
  2. (高级解决方案):将 [B] 标志添加到受影响的重写规则中:

    RewriteRule ^c/([^/]+)/([^-]+.+)/?$ /index.php/$2?c=$1 [L,QSA,B]
