使用 Dingo 在 Laravel 中没有模型的查询结果 - 如何在失败时做出 RESTful 响应? [英] No query results for model in Laravel with Dingo - how to make a RESTful response on failure?

问题描述

我正在使用基于 Dingo API 的 Laravel 创建 API.

I'm creating an API with Laravel based on the Dingo API.

在我的路线中，我有:

Route::api('v1', function () {
    Route::resource('object', 'My\Namespace\MyController');
});

在 MyController 中:

And in MyController:

class MyController extends \Illuminate\Routing\Controller {

    use Dingo\Api\Routing\ControllerTrait;

    public function index() {
        return MyObject::all();
    }

    public function show($id) {
        return MyObject::findOrFail($id);
    }

}

这意味着 api.domain.com/object 调用了 MyController@index，这是有效的.由于数据库中没有项目，因此会输出一个空的 json 数组 [].

This means that api.domain.com/object calls MyController@index, which works. Since there are no items in the database, this then outputs an empty json array [].

api.domain.com/object/123 调用 MyController@show(123).这是根据 https://github.com/dingo/api/wiki/Responses.但是，由于数据库中没有结果，我得到:

api.domain.com/object/123 calls MyController@show(123). This is according to https://github.com/dingo/api/wiki/Responses. However, since there are no results in the database, I get:

No query results for model [My\Namespace\MyObject].

我希望这会给出一个很好的 RESTful 错误.我该怎么做?

MyObject 的代码没有什么特别的，它是一个扩展 Illuminate\Database\Eloquent\Model 的空类.

The code of MyObject is nothing special, it's an empty class which extends Illuminate\Database\Eloquent\Model.

我使用的是 Laravel 4.2；Dingo 尚不支持 5.

I'm using Laravel 4.2; 5 is not supported by Dingo yet.

推荐答案

您必须自己处理并添加自定义错误，如此处.findOrFail() 会抛出一个 ModelNotFoundException 所以让我们抓住这个:

You'll have to handle it yourself and add a custom error as described here. findOrFail() will throw a ModelNotFoundException so let's catch that:

API::error(function (Illuminate\Database\Eloquent\ModelNotFoundException $e){
    return Response::make(['error' => 'Resource not found'], 404);
});
