控制器：

use think\Request;//引用请求类文件
use think\facade\View;//引用视图类文件
use think\facade\Db;//引用数据库链接类文件
//那么问题来了，为什么呢？因为举个例子。你不用电脑怎么写代码呢
public function uploadGoods(Request $request){//必须是请求才能进去的函数。比如postman.
    
        $file = $request->file('image');//数据库goods里面有个字段是image。存储图片的哈
        $savename = \think\facade\Filesystem::putFile( 'goods', $file,'md5');
        //存储在public/storage/goods目录下的图片
        return json(['code'=>1, 'msg'=>'上传成功', 'data'=> ['url'=>['/storage/'.$savename]]]);
    }
    

postman：

config/filesystem.php文件。粘贴复制

<?php

return [
    // 默认磁盘
    'default' => env('filesystem.driver', 'public'),//存储在public目录下
    // 磁盘列表
    'disks'   => [

            // 磁盘路径
            'root'       => app()->getRootPath() . 'public/storage',//public/storage目录下.然后还要什么目录。具体看代码操作
            // 磁盘路径对应的外部URL路径
            'url'        => '/storage',
            // 可见性
