Laravel 后备路由总是返回视图而不是 Json 响应

Question

使用 Laravel 构建 REST API。当客户端遇到不存在的路由时，我想返回一条 JSON 消息。

我有以下 api.php 文件：

<?php

use Illuminate\Http\Request;

Route::get('/', 'ListingController@getListingsAll')->name('all');


// No Authenticated Routes

Route::group(['prefix' => 'auth'], function () {
    Route::post('login', 'AuthController@login')->name('login');
    Route::post('register', 'AuthController@register')->name('register');
});

// Authenticated Routes

Route::group(['middleware' => 'auth:api'], function () {
    //Auth functions
    Route::group(['prefix' => 'auth'], function () {
        Route::get('logout', 'AuthController@logout');
        Route::get('user', 'AuthController@user');
    });

    //Listings

    Route::get('listings/user', 'ListingController@getListingsPerUser')->name('listings.user');
    Route::get('listings/all', 'ListingController@getListingsAll')->name('listings.all');
    ...
    ...
});


Route::fallback(function () {
    return response()->json(['message' => 'Not Found!'], 404);
});

每当我对 http://localhost:8000/foo 或 http://localhost:8000/api/foo 等执行 REST 调用时...它都会返回 404 Not found Blade 视图而不是 JSON 响应。

有什么想法吗？

最好在异常处理程序中实现这个

App\Exceptions\Handler.php

use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;

class Handler extends ExceptionHandler
{
    public function render($request, Exception $exception)
    {
        if ($exception instanceof NotFoundHttpException) {
            return response(['status' => 'Not Found'], 404);
        }
        return parent::render($request, $exception);
    }
}
