如何从 Laravel API 返回图像列表？

Question

如何从 Laravel API 返回图像列表？ 我想将 API 中的图像作为集合发送。我该怎么做？ 如果可能的话，我想使用 ProductCollection 资源来做到这一点。 从现在开始谢谢你。

我想从中获取文件数据：

   {
   "data": [
   {
   "id": 20,
   "name": "Cali Howe",
   "price": "4.00",
   "imageUrl": "C:\\Shop\\shop.api\\public\\img/default.png",
   "category_name": "Consequuntur ut.",
   "detail": "http://127.0.0.1:8000/api/product/20"
   },
   {
   "id": 19,
   "name": "Annie Murazik",
   "price": "13.00",
   "imageUrl": "C:\\Shop\\shop.api\\public\\img/default.png",
   "category_name": "Consequuntur ut.",
   "detail": "http://127.0.0.1:8000/api/product/19"
   }
   ],
   "links": {
   "first": "http://127.0.0.1:8000/api/product?page=1",
   "last": "http://127.0.0.1:8000/api/product?page=10",
   "prev": null,
   "next": "http://127.0.0.1:8000/api/product?page=2"
   },
   "meta": {
   "current_page": 1,
   "from": 1,
   "last_page": 10,
   "path": "http://127.0.0.1:8000/api/product",
   "per_page": 2,
   "to": 2,
   "total": 20
   }
   }

产品控制器：

public function index()
{
    return ProductCollection::collection(Product::orderBy('id', 'DESC')->paginate(2));
}

产品系列：

class ProductCollection extends JsonResource
{
     public function toArray($request)
     {
         return [
            'id' => $this->id,
            'name' => $this->name,
            'price' => $this->price,
            'imageUrl' => $this->imagePath('default.png'),
            'category_name' => $this->category->name,
            'detail' => route('product.show', $this->id),
        ];
     }
}

产品型号：

class Product extends Model
{
protected $guarded = ['id', 'created_at', 'updated_at'];

public function category()
{
    return $this->belongsTo(Category::class);
}

public function imagePath($fileName)
{
    return public_path('img/' . $fileName);
}
}

产品迁移：

public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->unsignedBigInteger('category_id');
        $table->string('name')->index();
        $table->decimal('price')->default(0);
        $table->string('image')->nullable();
        $table->timestamps();
        $table->foreign('category_id')->references('id')
            ->on('categories')->onDelete('cascade');
    });
}

您可以将图像转换为base64

$imagedata = file_get_contents("/path/to/image.jpg");
$base64 = base64_encode($imagedata);

编辑

class ProductCollection extends JsonResource
{
     public function toArray($request)
     {
         return [
            'id' => $this->id,
            'name' => $this->name,
            'price' => $this->price,
            'imageUrl' => $this->imagePath('default.png'),
            'category_name' => $this->category->name,
            'detail' => route('product.show', $this->id),
            'base64' => base64_encode(file_get_contents($this->imagePath('default.png')),
        ];
     }
}
