处理URL参数上的斜杠 [英] Handling slashes on URL parameters

问题描述

我遇到了一些问题，试图猜测如何使用Symfony + Twig上的参数处理URL.

I'm running into some issues trying to guess how to handle URLs with parameters on Symfony+Twig.

我有这条路线:

<route id="artist.front" path="/artist/{kw}/">
<default key="_controller">App\Web\Controllers\Front::homePage</default>
</route>

以下是Twig模板上的代码:

And this code on the Twig template:

{% autoescape false %}
<a href="{{ path('artist.front',{'kw':a.urlkeyword|url_encode} )}}">{{ a.name }}</a>
{% endautoescape %}

urlkeyword参数按原样(即先前未编码的URL)在实体构造函数及其getter(getURLKeyword)上传递.

urlkeyword parameter is passed as is (i.e. not URL encoded previously) both on the entity constructor and on its getter (getURLKeyword).

但是，在渲染模板时，我得到了以下HTML代码:

However, when rendering the template I get this HTML code:

<a href="/index.php/artist/AC%252FDC/">AC/DC</a>

(如果我从模板中删除url_encode，Twig会引发调用path()的错误.)

(If I remove the url_encode from the template Twig throws an error calling path()).

目标控制器具有以下代码:

The target controller has this code:

public function artistPage($kw)
{
    $decoded = urldecode($kw);
    $this->log->info("kw:      {$kw}");
    $this->log->info("decoded: {$decoded}");
}

并回声:

kw:      AC%2FDC 
decoded: AC/DC 

所以我认为可以从控制器正确读取kw，但我知道应该将URL编码为AC％2FDC，而不是首先放在最终的HTML代码上:URLEncoded字符串被编码两次.

so I think the kw is read correctly from the controller, but I understand the URL should be encoded as AC%2FDC instead on the final HTML code on the first place: The URLEncoded string is encoded twice.

AC％2FDC是正确的编码，还是有必要在Symfony中使用双重编码(AC％252FDC)?而且，如果可以使用第一种(正确的)URL编码，那么我在做什么错了?

Is AC%2FDC the correct encoding, or is it necessary to use the double encoding (AC%252FDC) in Symfony? And, if it is possible to use the first (correct) URL encoding, what I am doing wrong?

推荐答案

尝试:

<route id="artist.front" path="/artist/{kw}/">
    <default key="_controller">App\Web\Controllers\Front::homePage</default>
    <requirement key="kw">.+</requirement>
</route>

并删除网址编码/解码.

And remove the url encoding/decoding.
