警告

路由分发策略将受到影响，请在充分测试后才能应用于生产环境。

所有参数必须在方法参数列表中明确定义，并且参数名称必须与路由中定义的相匹配。

以下调用可能会有影响。

class SomeController extends Controller
{
    // For route: /{a}/{b}/{c}
    // ❌ Method's parameter list is empty.
    public function method()
    {
        $a = func_get_args()[0];
        $b = func_get_args()[1];
        $c = func_get_args()[2];
    }

    // For route: /{a}/{b}/{c}
    // ❌ Parameter name does not match the variable name defined in the route.
    public function method($aa, $bb, $cc)
    {
        // ....
    }

    // For route: /{a}/{b}/{c}
    // ❗️ The number of parameters does not match the number of variables defined in the route.
    public function method($a, $b)
    {
        $c = func_get_args()[2];
    }

    // For route: /{a}/{b}/{c}
    // ✅
    public function method($a, $b, $c)
    {
        // .....
    }

    // For route: /{a}/{b}/{c}
    // ✅
    public function method($c, $a, $b)
    {
        return $c.'-'.$a.'-'.$b;
        // /a/b/c
        // output: c-a-b
    }
}

用法

// AppServiceProvider::boot
URL::defaults(['locale' => 'en-us']);
// route('home.test', ['name'=>'hello']) => /en-us/hello
// route('home.test', ['name'=>'hello', 'locale'=>'fr']) => /fr/hello

// global middleware
...
app()->setLocale($request->route('locale', '...'))
$request->setLocale($request->route('locale', '...'))
...

use \Illuminate\Support\Facades\Route;

Route::prefix('/{locale?}')
    ->whereIn('locale', ['en-us', 'fr', 'zh-CN', 'zh-HK'])
    ->group(function (\Illuminate\Routing\Router $router) {
        $router->get('/{name}', 'Home@test')->name('home.test');
    });

// Controller
class Home extends Controller
{
    public function test(\Illuminate\Http\Request $request, string $name)
    {
        $locale = $request->getLocale();
        return $name;
    }
}
