Question

我在我的项目图像包Intervention-Image中使用将水印添加到服务中的每个上载图像中，我使用代码打击，但哈希处理出错哈希仅每次给我watermark.png的哈希

Route::post('/upload_image',function (Request $request)
{

    $real_path = Image::make($request->file('image')->getRealPath());

    $img_for_hash = Image::make($real_path);

    $img = Image::make($real_path);

    //  calculate md5 hash of encoded image
     $hash = md5($img_for_hash->__toString());

     // use hash as a name
    $path = "images/{$hash }.jpg";



    $watermark =  Image::make(public_path('watermark.png'));



    $img->insert($watermark, 'bottom-right', 10, 10);



    // save it locally to ~/public/images/{$hash}.jpg
    $img->save(public_path($path));

    return $hash ;

})->name('upload_image');

      <input type="file" name="image">

     <button type="submit"> upload </button>

      </form>

任何解决方案都使用回叫还是因为水印？我不知道为什么这段代码每次都会给我同样的哈希值。
