Fractal.php线路348中的Laravel 5.4 - InvalidTransformation。

Question

如你所知，laravel-fractal是最好的API开发包之一。从今天开始，我面临着一个问题，当我试图将代码部署到远程服务器时，会抛出像标题这样的错误。我想让你知道，build在我的本地机器上运行得很好。

当我在UserTransformer中dd $user时，所有属性看起来都很好，而且不出所料，它是一个用户实例。我也有同样的问题，类别，新闻和页面转换器。有一个变压器在工作，但结构是相同的，所以我不知道发生了什么。

下面是我的代码片段：

UserTransformer.php

class UserTransformer extends TransformerAbstract
{

    protected $defaultIncludes = ['token'];

    /**
     * A Fractal transformer.
     * @param User $user
     * @return array
     */
    public function transform(User $user)
    {
        return [
            'email' => $user->email,
        ];
    }

    public function includeToken(User $user){
        $token = $user->createToken('Access')->accessToken;
        return $this->item($token,new TokenTransformer());
    }
}

TokenTransformer.php

class TokenTransformer extends TransformerAbstract
{
    /**
     * A Fractal transformer.
     * @param $token
     * @return array
     */
    public function transform($token)
    {
        return [
            'token' => $token
        ];
    }
}

api.php

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return fractal()
        ->item($request->user())
        ->transformWith(new \App\Transformers\Auth\UserTransformer)
        ->toArray();
});

错误：

InvalidTransformation in Fractal.php line 348:
in Fractal.php line 348
at Fractal->getResource() in Fractal.php line 333
at Fractal->createData() in Fractal.php line 304
at Fractal->toArray() in api.php line 20
at Router->{closure}(object(Request)) in Route.php line 189

也许我遗漏了什么，所以我也发布了类别转换器

CategoryTransformer.php

class CategoryTransformer extends TransformerAbstract
{

    protected $defaultIncludes = ['nodes'];
    protected $availableIncludes = ['pages'];

    /**
     * A Fractal transformer.
     * @param Category $category
     * @return array
     */
    public function transform(Category $category=null)
    {
        if($category){

            return [
                'parent' => $category->parent->slug ?? false,
                'name' => $category->name,
                'slug' => $category->slug,
                'page_count' => $category->pages()->count(),
                'info' => []
            ];
        }

        return [];

    }


    public function includeNodes(Category $category){
        $nodes = $category->children;
        return $this->collection($nodes,new CategoryTransformer,['nodes']);
    }


    public function includePages(Category $category){
        return $this->collection($category->pages,new PageTransformer());
    }
}

CategoryController.php

public function show(Category $category,Request $request){

    //API

        return fractal()
            ->item($category)
            ->transformWith(new CategoryTransformer())
            ->parseIncludes(['pages','nodes.pages'])
            ->toArray();


}

谢谢。

Answer 1

稍加研究后，我发现我的语言环境是tr，在Fractal.php第345行，大写的'i‘是'İ’，而不是'I‘。

$resourceClass = 'League\\Fractal\\Resource\\'.ucfirst($this->dataType);

返回League\Fractal\Resource\item而不是League\Fractal\Resource\Item

我不知道如何在不更改src代码的情况下修复它。但现在，我将api路由和控制器的locale更改为en，看起来还不错。
