所以我在最新的 Laravel 5.1 上，今天更新到 5.2。在我的路线中，我有这样的事情：

Route::group(['middleware' => ['api']], function() {
    // Members
    Route::get('members', '{api-namespace}\MembersController@index');
    Route::get('member/{id}', '{api-namespace}\MembersController@show');

    // Members Pension
    Route::get('member/{id}/pension/beneficiaries', '{api-namespace}\Inquiry\MembersPensionController@showBeneficiaries');
    Route::get('member/{id}/pension/contributions', '{api-namespace}\Inquiry\MembersPensionController@showContributions');
    Route::get('member/{id}/pension/yearlySummary', '{api-namespace}\Inquiry\MembersPensionController@showYearlySummary');
    Route::get('member/{id}/pension/pensioners', '{api-namespace}\Inquiry\MembersPensionController@showPensioners');

    // Members Summary
    Route::get('member/{id}/beneficiaries/{fund?}', '{api-namespace}\BeneficiariesController@showByMember');
    Route::get('member/{id}/contributions/', '{api-namespace}\ContributionsController@showByMember');

    // Beneficiaries
    Route::get('beneficiaries', '{api-namespace}\BeneficiariesController@index');
    Route::get('beneficiary/{id}', '{api-namespace}\BeneficiariesController@show');

    // Contributions
    Route::get('contributions', '{api-namespace}\ContributionsController@index');

    Route::get('users', '{api-namespace}\UsersController@index');
});

api-version 中间件基本上检查 api-version 的标头，然后在路由操作中适当地填写 {api-namespace}。这在 5.1 中运行良好。但是，自从升级以来Class App\\Http\\Controllers\\{api-namespace}\\MembersController does not exist，它甚至根本没有影响我的中间件。我有一种感觉，他们可能已经切换了代码的顺序，以便在运行中间件之前验证路由操作，因为如果我将中间件放在全局范围内，它就可以正常工作。但是，我需要这个 api-version 组，所以如果有人知道如何解决这个问题，我会全力以赴。

按要求：

内核.php

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{
    /**
     * The application's global HTTP middleware stack.
     *
     * @var array
     */
    protected $middleware = [
        \Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
        \App\Http\Middleware\EncryptCookies::class,
        \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
        \Illuminate\Session\Middleware\StartSession::class,
        \Illuminate\View\Middleware\ShareErrorsFromSession::class,
    ];

    /**
     * The application's route middleware.
     *
     * @var array
     */
    protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'api-version' => \App\Http\Middleware\ApiVersionMiddleware::class,
    ];

    /**
     * The application's route middleware groups.
     *
     * @var array
     */
    protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
        ],
        'api' => [
            'throttle:60,1',
            'api-version',
            'cors'
        ],
    ];
}

ApiVersionMiddleware.php

<?php namespace App\Http\Middleware;

use Closure;
use Jbm\Exceptions\ApiVersionException;
use Jbm\Helpers\ApiVersion;

class ApiVersionMiddleware
{

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $route = $request->route();
        $actions = $route->getAction();

        $requestedApiVersion = ApiVersion::get($request);
        if (!ApiVersion::isValid($requestedApiVersion)) {
            throw new ApiVersionException('Invalid API Version');
        }

        $apiNamespace = ApiVersion::getNamespace($requestedApiVersion);

        $actions['uses'] = str_replace(
            '{api-namespace}', $apiNamespace, $actions['uses']
        );

        $route->setAction($actions);

        return $next($request);
    }
}

另请注意，我将中间件移到了中间件组中，但它仍然无法正常工作。仅供参考

更新：

我尝试将中间件移动到全局，但此时它有 0 有关路由的信息，这意味着它无法修改要替换的路由{api-namespace}。我认为问题是在中间件运行之前检查了“使用”的路线，这显然失败了。谁能证实这一点和/或告诉我如何在 5.2 中实现这样的东西？

更新 2：

所以我发现了这个问题。在Illuminate/Routing/Router.php:834路由器中尝试替换隐式绑定。这发生在中间件之前并检查有效“使用”的路由。我不知道如何解决这个问题，因为它完全颠覆了我目前正在做的事情。有什么建议么？

所以这实际上最终成为了一个错误，现在从最新版本的 laravel 5.2 开始修复：请参见此处https://github.com/laravel/framework/issues/11261
