如何在Zend Framework 2中为RegEx路由的RegEx设置(UTF8)修饰符?

[英]How to set a (UTF8) modifier for RegEx of a RegEx Route in Zend Framework 2?

在URI遇到了(德语)特殊字符的麻烦,想要尝试使用RegEx Route和UTF-8 uPCRE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,路径就会停止工作(错误404) - 既不是URI也不是没有特殊字符的URI。

如何正确设置修改器?

因为我已经在这里打开了这个解决问题的处理程序。

<?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);
    }
}

假设您将文件放在Application/Mvc/Router/Http/UnicodeRegex您的路由定义应该如下所示

'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,
        ),
    ),
),

好,

我猜你可以像许多其他人一样容易解决这个问题。 所以看看其中一些:

UTF-8 in *正则表达式

使用以下修饰符,如\\\\s\\\\p{L}\\\\u\u003c/code>来帮助您。 我希望它能解决! 祝好运。

看我自己的测试:

<?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?

对你来说可能更好!

<?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

?>
