laravel - 调整图像大小并保存到 Amazon S3

Question

当用户上传他的个人资料图片时，我想为这张图片创建 3 个不同尺寸的版本，然后将所有内容上传到亚马逊 s3。

我使用图像干预包来调整图像大小，这是我目前的代码。

public function store(Request $request){

    if($request->has('avatar')){

        $avatar = $request->file('avatar');

        $filename = md5(time()).'_'.$avatar->getClientOriginalName();

        $normal = Image::make($avatar)->resize(160, 160);

        $medium = Image::make($avatar)->resize(80, 80);

        $small = Image::make($avatar)->resize(40, 40);

        Storage::disk('s3')->put('/users/'.Auth::user()->uuid.'/avatars/normal/'.$filename, fopen($normal, 'r+'), 'public');

        Storage::disk('s3')->put('/users/'.Auth::user()->uuid.'/avatars/medium/'.$filename, fopen($medium, 'r+'), 'public');

        Storage::disk('s3')->put('/users/'.Auth::user()->uuid.'/avatars/small/'.$filename, fopen($small, 'r+'), 'public');

        $user = User::findorFail(Auth::user()->id);
        $user->avatar = $filename;
        $user->save();

        return redirect()->back();
    }

}

当我尝试提交文件时，出现此错误。

fopen(): Filename cannot be empty

更新我让它像这样工作，如果有人有同样的问题，我希望他会发现这段代码有帮助。

public function store(Request $request){

    if($request->has('avatar')){

        $avatar = $request->file('avatar');
        $extension = $request->file('avatar')->getClientOriginalExtension();

        $filename = md5(time()).'_'.$avatar->getClientOriginalName();

        $normal = Image::make($avatar)->resize(160, 160)->encode($extension);
        $medium = Image::make($avatar)->resize(80, 80)->encode($extension);
        $small = Image::make($avatar)->resize(40, 40)->encode($extension);

        //$path = '/users/'.Auth::user()->uuid.'/avatar/normal/'.$filename;

        //dd($normal);

        Storage::disk('s3')->put('/users/'.Auth::user()->uuid.'/avatar/normal/'.$filename, (string)$normal, 'public');

        Storage::disk('s3')->put('/users/'.Auth::user()->uuid.'/avatar/medium/'.$filename, (string)$medium, 'public');

        Storage::disk('s3')->put('/users/'.Auth::user()->uuid.'/avatar/small/'.$filename, (string)$small, 'public');

        $user = User::findorFail(Auth::user()->id);
        $user->avatar = $filename;
        $user->save();

        return redirect()->back();
    }

}
