控制器代码实现

图像处理需安装第三方依赖 composer require intervention/image
修改 app/config/app.php 添加 ServiceProvider:

'providers' => [
    // ...
    Intervention\Image\ImageServiceProvider::class,
    // ...
  ],

// 将下面代码添加到 aliases 数组中
'aliases' => [
    // ...
    'Image' => Intervention\Image\Facades\Image::class,
    // ...
  ],

public function upfile(Request $request){
        $pic=config('up.pic');
        if ($request->hasFile('file')){
            //上传
            //参数2 配置节点名称
            $ret=$request->file('file')->store('goods');

            $image='/uploads/'.$ret;
            //相对路径
            $img='./uploads/'.$ret;
            //绝对路径
            //public_path().'/uploads/'.$ret
            //直接生成略缩图
