Question

我正在用Laravel编写端点。当我在Postman上进行测试时，出现此错误：

ErrorException：尝试获取文件C：\ xampp \ htdocs \ testing-file \ testing \ vendor \ laravel \ framework \ src \ Illuminate \ Http \ Resources \ DelegatesToResource.php中非对象的属性'id' 120

控制器

public function showBilling($id)
{
     return new BillingResource($id);       
}

型号

class Billing extends Model
{
    protected $table = 'billing';

    protected $fillable = [
        'network' ,
        'sender',
        'recipient',
        'message',
        'timestamp',
        'created_at',
        'updated_at',
        'amount',
        'billing_type',
        'user_id',
        'service_name',
        'package',
        'email',
        'user_id'
    ];    


    public function user() {
        return $this->belongsTo('App\User');
    }

}

资源

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;
use App\Billing;

class BillingResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'network' => $this->network,
            'sender' => $this->sender,
            'recipient' => $this->recipient,
            'message' => $this->message,
            'amount' => $this->amount,
            'billing_type' => $this->billing_type,
            'email' => $this->email,
            'user' => $this->user,
            'service' => $this->service,
            'package' => $this->package,
            // Casting objects to string, to avoid receive create_at and update_at as object
            'timestamp' => (string) $this->timestamp,          
            'created_at' => (string) $this->created_at,
            'updated_at' => (string) $this->updated_at
          ];
    }
}

如果我使用此GET请求：

http://localhost/testing-file/testing/api/showBilling/56

应该显示受影响的行，但出现此错误：

ErrorException：尝试获取文件C：\ xampp \ htdocs \ testing-file \ testing \ vendor \ laravel \ framework \ src \ Illuminate \ Http \ Resources \ DelegatesToResource.php中非对象的属性“ id” 120

Answer 1

尝试将模型提供给资源，而不仅仅是ID：

public function showBilling($id)
{
     return new BillingResource(Billing::find($id));       
}

您还可以按照Andrew G的建议使用路由模型绑定。

Answer 2

您好，Mofolumike，欢迎您使用StackOverflow！据我所知，问题在于路由模型绑定错误。您需要更改的只是：

public function showBilling(Billing $billing)
{
     return new BillingResource($billing);       
}

此外，您需要确保路由具有有效的参数名称。例如（routes / api.php）：

Route::get('some/path/{billing}', 'BillingController@showBilling');

Answer 3

尝试将模型提供给资源，而不仅仅是ID：

public function show($id)
{
     return BillingResource::make(Billing::find($id));       
}

public function show(Billing $billing)
{
     return BillingResource::make($billing);       
}

这是您的路线：

Route::get('/billings/{billing}','BillingController@show');
