Question

我正在尝试上载图像，将其存储在磁盘上，并将路径添加到存储在数据库中的JSON文件。每个用户都有一个包含所有图像的JSON文件，例如：

{"images": ["/vendors/57/horse-11.png", "/vendors/57/horse-11.png"]}

该JSON文件存储在数据库中“图像”列中。

几天来我一直在努力解决这个问题。.我总是遇到以下异常：

Serialization of 'Illuminate\Http\UploadedFile' is not allowed

该错误发生在processImage函数的这段代码中：

$image = Image::make($request->file('image'))
                ->resize(750, null, function ($constraint) {
                    $constraint->aspectRatio();
                })
                ->encode('png');

我将指导您进行操作：

首先，用户上传图片，代码：

https://codeshare.io/jGzQ9

其次，通过routes.php，一个控制器被称为：

public function update(User $user, UserHouse $house, UserHouseRequest $request){
    $path = $this->processImage($request, $user->id, $house->id);
    $jsonstring = $house->images;
    array_push($jsonstring['images'], $path);

    $house->images = $jsonstring;
    $house->save();

    return back();
}

private function processImage($request, $userId, $houseId)
{
    $path = null;
    $number = rand(1, 99);
    if ($request->hasFile('image')) {
        $image = Image::make($request->file('image'))
            ->resize(750, null, function ($constraint) {
                $constraint->aspectRatio();
            })
            ->encode('png');
        $path = "/users/{$userId}/house-{$houseId}-{$number}.png";
        Storage::disk('fileadmin')->put($path, $image->encoded);
    }

    return $path;
}

也有一些JS代码，但是我认为这对于此问题不是必需的。如果可以，我以后再添加。

我正在使用Laravel 5.5
