Laravel Dingo Api-如何从Api控制器返回JSON格式的错误响应？

Question

在我的routes.php中，我有以下内容：

$apiSettings = [
    'version' => 'v1',
    'prefix' => 'api',
    'protected' => true
];   
Route::api($apiSettings, function() {
    Route::get('venue', 'ApiDataController@venue');
});

public function venue(){

    try {
        //Some code that returns an exception
    } catch(someexception $e) {
        //How do I return the exception such that Dingo will parse it into a proper JSON response?
    }
    $response = Venue::with('address')->get();
    return $response;

}

try {
    //some code that returns an exception
} catch(someexception $e) {
    $response = array(
        'message' => 'some random exception message'
    );
    return Response::json($response, 403);
}

public function venue(){
    throw new Symfony\Component\HttpKernel\Exception\ConflictHttpException('err);
}

在构建api时，可以在全局范围内捕捉类似类型的异常。例如，如果用户试图获得一个ID不存在的客户，那么您可以这样做。

Customer::findOrFail($id);

然后，您可以在app/start/global.php中捕获所有此类型异常，如下所示。

App::error(function(ModelNotFoundException $modelNotFoundException){
    $errorResponse = [
        'errors'    => 'Not found any resource',
        'message'   => $modelNotFoundException->getMessage()
    ];

    return Response::json($errorResponse, 404);     //404 = Not found
});
