我在uri中遇到(德语)特殊字符的麻烦，并想尝试用RegEx路由和用于UTF-8 u的PCRE模式修饰符来解决它。
'router' => array(
'routes' => array(
// ...
'city' => array(
'type' => 'regex',
'options' => array(
'regex' => '/catalog/(?<city>[a-zA-Z0-9_-äöüÄÖÜß]*)'/u',
'defaults' => array(
'controller' => 'Catalog'Controller'Catalog',
'action' => 'list-sports',
),
'spec' => '/catalog/%city%',
),
'may_terminate' => true,
),
),
),
但是当我设置它时，路由完全停止工作(错误404)—无论是对于带有特殊字符的uri还是对于没有特殊字符的uri。
如何正确设置修饰语?
因为我已经打开了这个，所以这里有一个处理程序来解决这个问题。
<?php
namespace Application'Mvc'Router'Http;
use Zend'Mvc'Router'Http'Regex;
use Zend'Mvc'Router'Http'RouteMatch;
use Zend'Stdlib'RequestInterface as Request;
class UnicodeRegex extends Regex
{
/**
* match(): defined by RouteInterface interface.
*
* @param Request $request
* @param integer $pathOffset
* @return RouteMatch
*/
public function match(Request $request, $pathOffset = null)
{
if (!method_exists($request, 'getUri')) {
return null;
}
$uri = $request->getUri();
// path decoded before match
$path = rawurldecode($uri->getPath());
// regex with u modifier
if ($pathOffset !== null) {
$result = preg_match('('G' . $this->regex . ')u', $path, $matches, null, $pathOffset);
} else {
$result = preg_match('(^' . $this->regex . '$)u', $path, $matches);
}
if (!$result) {
return null;
}
$matchedLength = strlen($matches[0]);
foreach ($matches as $key => $value) {
if (is_numeric($key) || is_int($key) || $value === '') {
unset($matches[$key]);
} else {
$matches[$key] = $value;
}
}
return new RouteMatch(array_merge($this->defaults, $matches), $matchedLength);
}
}
假设你把文件放在Application/Mvc/Router/Http/UnicodeRegex中，你的路由定义应该是这样的
'router' => array(
'routes' => array(
// ...
'city' => array(
'type' => 'Application'Mvc'Router'Http'UnicodeRegex',
'options' => array(
'regex' => '/catalog/(?<city>['p{L}]+)',
// or if you prefer, your original regex should work too
// 'regex' => '/catalog/(?<city>[a-zA-Z0-9_-äöüÄÖÜß]*)',
'defaults' => array(
'controller' => 'Catalog'Controller'Catalog',
'action' => 'list-sports',
),
'spec' => '/catalog/%city%',
),
'may_terminate' => true,
),
),
),
嗯，
我想你可以像其他许多人遇到同样的问题一样轻松地解决它。来看看其中的一些:
*正则表达式中的UTF-8
使用以下修饰符，如''s, ''p{L}和''u来帮助您。我希望它能解决!好运。

见my own test:
<?php
$toss_the_dice = utf8_decode ("etc/catalog/Nürnberg");
preg_match ('/'/catalog'/([''s''p{L}]*)/m', $toss_the_dice, $dice);
echo utf8_encode ($dice[1]);
// Now it prints
// Nürnberg
?>
你能意识到吗?

这对你来说会更好!
<?php
$toss_the_dice = "etc/catalog/Nürnberg";
preg_match ('/'/catalog'/([''s''p{L}]*)/u', $toss_the_dice, $dice);
echo $dice[1];
// Now it also prints
// Nürnberg
?>
