Laravel使用regexp的可选前缀路由 [英] Laravel optional prefix routes with regexp

问题描述

有没有一种方法可以创建带有前缀的路由，这样我就可以拥有这样的路由

Is there a way to create routes with prefixes so I can have routes like this

/articles.html -> goes to listing  Controller in default language
/en/articles.html -> goes to the same controller
/fr/articles.html -> goes to the same controller

我当前的问题是这样做:

My current problem is that by doing:

Route::group(['prefix=>'/{$lang?}/',function(){});

这样的路由:/authors/author-100.html将匹配前缀'authors'，并且肯定没有称为"authors"的语言.

a route like this: /authors/author-100.html will match a prefix 'authors` , and for sure there is no language called "authors".

我使用laravel 5.5

I use laravel 5.5

推荐答案

使用可选的route参数上的where Regex匹配，这应该足够了:

This should be sufficient using the where Regex match on the optional route parameter:

Route::get('/{lang?}, 'SameController@doMagic')->where('lang', 'en|fr');

您也可以在路由组上执行相同的操作，否则显然可以使用此答案中的所有选项.

You can do the same on Route Group as well, else having all the options as in this answer evidently works.

更新以显示前缀的使用:

An update to show the use of prefix:

Route::group(['prefix' => '{lang?}', 'where' => ['lang' => 'en|fr']],function (){
    Route::get('', 'SameController@doNinja');
});

就我而言，即使没有lang也有足够的语言，这应该足够了，也许这组语言可能早于其他路线.

As far as I am concerned this should be sufficient even when there is no lang as well as when there is one, just maybe this group could come before other routes.
