带有德语特殊字符的 URI 在 Zend Framework 2 中不起作用(错误 404) [英] URIs with german special characters don't work (error 404) in Zend Framework 2

问题描述

我想获得一个城市列表，其中每个城市名称都被链接并引用该城市的一个页面:

I want to get a list of cities, where each city name is linked and refers a page for this city:

链接(在视图脚本中创建)如下所示:

The links (created in the view script) look like this:

http://project.loc/catalog/Berlin (in the HTML source code url-encoded: Berlin)
http://project.loc/catalog/Erlangen (in the HTML source code url-encoded: Erlangen)
http://project.loc/catalog/Nürnberg (in the HTML source code url-encoded: N%C3%BCrnberg)

"Berlin", "Erlangen" 等工作，但如果城市名称包含德语特殊字符 (ä, ö, ü>、Ä、Ö、Ü 或 ß) 像纽伦堡"一样，会出现 404 错误:

"Berlin", "Erlangen" etc. work, but if the city name contains a german special character (ä, ö, ü, Ä, Ö, Ü, or ß) like "Nürnberg", a 404 error occurs:

发生 404 错误页面未找到.请求的 URL 不能为通过路由匹配.没有可用的异常

A 404 error occurred Page not found. The requested URL could not be matched by routing. No Exception available

为什么?以及如何让它发挥作用?

Why? And how to get this working?

提前致谢！

我的路由器设置:

'router' => array(
    'routes' => array(
        'catalog' => array(
            'type'  => 'literal',
            'options' => array(
                'route' => '/catalog',
                'defaults' => array(
                    'controller' => 'Catalog\Controller\Catalog',
                    'action'     => 'list-cities',
                ),
            ),
            'may_terminate' => true,
            'child_routes' => array(
                'city' => array(
                    'type'  => 'segment',
                    'options' => array(
                        'route' => '/:city',
                        'constraints' => array(
                            'city'  => '[a-zA-ZäöüÄÖÜß0-9_-]*',
                        ),
                        'defaults' => array(
                            'controller' => 'Catalog\Controller\Catalog',
                            'action'     => 'list-sports',
                        ),
                    ),
                    'may_terminate' => true,
                    'child_routes' => array(
                    // ...
                    ),
                ),
            ),
        ),
    ),
),

推荐答案

您需要更改约束，您可以使用匹配 UTF8 字符的正则表达式，例如:

You need to change your constraints, you can use a regular expression which will match UTF8 characters, something like this:

'/[\p{L}]+/u'

注意/u 修饰符(unicode).

Notice the /u modifier (unicode).

问题已解决.

说明:

RegEx 路由将 URI 与 preg_match(...)(行 116 或 118 的 Zend\Mvc\Router\Http\Regex).为了处理带有特殊字符"(128+)的字符串，必须将模式修饰符 u 传递给 preg_match(...).像这样:

The RegEx Route maches the URIs with preg_match(...) (line 116 or 118 of Zend\Mvc\Router\Http\Regex). In order to mach a string with "special chars" (128+) one must pass the pattern modifier u to preg_match(...). Like this:

$thisRegex = '/catalog/(?<city>[\p{L}]*)';
$regexStr = '(^' . $thisRegex . '$)u'; // <-- here
$path = '/catalog/Nürnberg';
$matches = array();
preg_match($regexStr, $path, $matches);

并且由于 RegEx Route 将 url 编码的字符串传递给 preg_match(...)，因此需要先对字符串进行进一步解码:

And since RegEx Route passes a url-enccoded string to preg_match(...), it's furthermode needed to decode the string first:

$thisRegex = '/catalog/(?<city>[\p{L}]*)';
$regexStr = '(^' . $thisRegex . '$)u';
$path = rawurldecode('/catalog/N%C3%BCrnberg');
$matches = array();
preg_match($regexStr, $path, $matches);

RegEx Route 中没有提供这两个步骤，所以 preg_match(...) 得到了类似 '/catalog/N%C3%BCrnberg'并尝试将其转换为像 '/catalog/(?<city>[\\p{L}]*)/u'

These two steps are not provided in the RegEx Route, so that preg_match(...) gets a steing like '/catalog/N%C3%BCrnberg' and tries to mach it to a regex like '/catalog/(?<city>[\\p{L}]*)/u'

解决方案是使用自定义 RegEx 路由.这里是一个例子.

The solution is to use a custom RegEx Route. Here is an example.
