调研方向

使用 Routes.php 中的路由重现失败,并在 Routing.php 的 multipleSegmentsOneParam 两种设置下比较 url_to 和 route_to。首先从命名正则表达式路由开始跟踪路由参数的处理;完成的标准是所有显示的链接都能生成,不出现 InvalidArgumentException,并保留预期的参数。

由索引模型根据 Issue 内容生成。

What happened?

The following route definition works fine as long as you don't use url_to or route_to to refer to it:

$routes->get('/test(/(:any))?', 'Test::direct/$1', ['as' => 'test']);

Linking as below works:

<a href="/test">No parameter</a>
<a href="/test/param1">1 parameter</a>
<a href="/test/param1/param2">2 parameters</a>

But using both url_to or route_to fails:

<a href="<?= url_to('test') ?>">No parameter</a>
<a href="<?= url_to('test', 'param1') ?>">1 parameter</a>
<a href="<?= url_to('test', 'param1', 'param2') ?>">2 parameters</a>
Steps to Reproduce
  1. Add the new routes in Routes.php:
$routes->get('/test(/(:any))?', 'Test::direct/$1', ['as' => 'test']);
$routes->get('/test_urlto(/(:any))?', 'Test::urlto/$1', ['as' => 'urlto']);
$routes->get('/test_routeto(/(:any))?', 'Test::routeto/$1', ['as' => 'routeto']);
  1. Create the Test controller:
<?php

namespace App\Controllers;

class Test extends BaseController
{
    public function direct(...$params): string
    {
        return view('test', ['params' => $params]);
    }

    public function urlto(...$params): string
    {
        return view('test_urlto', ['params' => $params]);
    }

    public function routeto(...$params): string
    {
        return view('test_routeto', ['params' => $params]);
    }
}
  1. Create the respective views:

A) direct view

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>Test</title>
</head>
<body>
	<h1>Testing CI4 Routing with Parameters</h1>

	<h2>Test using string directly</h2>
	<ul>
		<li>
			<a href="/test">No parameter</a>
		</li>
		<li>
			<a href="/test/param1">1 parameter</a>
		</li>
		<li>
			<a href="/test/param1/param2">2 parameters</a>
		</li>
		<li>
			<a href="/test/param1/param2/param3">3 parameters</a>
		</li>
	</ul>
	<h3>Passed Parameters</h3>
	<ul>
		<?php foreach ($params as $param) : ?>
			<li><?= $param ?></li>
		<?php endforeach; ?>
</body>
</html>

B) view using url_to

<!DOCTYPE html>
<html lang="en">

<head>
	<meta charset="UTF-8">
	<title>Test</title>
</head>

<body>
	<h1>Testing CI4 Routing with Parameters</h1>
	<h2>Test using <code>url_to</code></h2>
	<ul>
		<li>
			<a href="<?= url_to('urlto') ?>">No parameter</a>
		</li>
		<li>
			<a href="<?= url_to('urlto', 'param1') ?>">1 parameter</a>
		</li>
		<li>
			<a href="<?= url_to('urlto', 'param1', 'param2') ?>">2 parameters</a>
		</li>
		<li>
			<a href="<?= url_to('urlto', 'param1', 'param2', 'param3') ?>">3 parameters</a>
		</li>
	</ul>

	<h3>Passed Parameters</h3>
	<ul>
		<?php foreach ($params as $param) : ?>
			<li><?= $param ?></li>
		<?php endforeach; ?>
</body>
</html>
  1. Access those views at: /test and /test_urlto
Expected Output

No InvalidArgumentException, Missing argument for "(/(:any)" in route "test_urlto(/(:any))?" while using both url_to and route_to .

Anything else?
  • One can try it with public bool $multipleSegmentsOneParam = true; or public bool $multipleSegmentsOneParam = false; in Routing.php. The error is the same in both situations (just the parameters are treated differently, as expected).

  • One can also use a regex like '(/(.+))?' instead of (/(:any))? . The error remains.
