如何对URL中未知数量的参数使用laravel路由? [英] How to use laravel routing for unknown number of parameters in URL?

问题描述

例如，我正在出版包含章节，主题和文章的图书:

For example, I'm publishing books with chapters, topics, articles:

http://domain.com/book/chapter/topic/article

我将使用带有参数的Laravel路线:

I would have Laravel route with parameters:

Route::get('/{book}/{chapter}/{topic}/{article}', 'controller@func')

在Laravel中是否可能有一条规则可以满足书本结构中未知数量的级别(类似于

Is it possible, in Laravel, to have a single rule which caters for an unknown number of levels in the book structure (similar to this question)? This would mean where there are sub-articles, sub-sub-articles, etc..

推荐答案

您需要的是可选的路由参数:

What you need are optional routing parameters:

//in routes.php
Route::get('/{book?}/{chapter?}/{topic?}/{article?}', 'controller@func');

//in your controller
public function func($book = null, $chapter = null, $topic = null, $article = null) {
  ...
}

有关更多信息，请参阅文档: http://laravel.com/docs/5.0 /routing#route-parameters

See the docs for more info: http://laravel.com/docs/5.0/routing#route-parameters

更新:

如果您希望文章后的参数数量不受限制，则可以执行以下操作:

If you want to have unlimited number of parameters after articles, you can do the following:

//in routes.php
Route::get('/{book?}/{chapter?}/{topic?}/{article?}/{sublevels?}', 'controller@func')->where('sublevels', '.*');

//in your controller
public function func($book = null, $chapter = null, $topic = null, $article = null, $sublevels = null) {
  //this will give you the array of sublevels
  if (!empty($sublevels) $sublevels = explode('/', $sublevels);
  ...
}
