thinkphp 图片上传验证

thinkphp中已经有对图片上传做了很好的验证 使用如下:

验证器类中写:

namespace app\index\validate;

use think\Validate;

class User extends Validate
{
    protected $rule = [
        'test' => ['require', 'image' => '225,225', 'fileExt' => 'png,jpg', 'fileSize' => 6500],
    ];

    protected $message = [
        'test.image' => '不是225,225的图形',
        'test.fileExt' => '图片的格式不符合要求',
        'test.fileSize' => '内容不能大于6500字节',
    ];

    protected $scene = [
        'edit' => ['test'](这里是场景)
    ];

控制器中验证:

public function trr(Request $request)
    {
        //获取上传文件
        $file = $request->file('image');
        //先验证是否满足条件
        $result = $this->validate(['test' => $file], 'User.edit');
        if (true === $result) {
            //满足条件再做业务逻辑
            $info = $file->move(ROOT_PATH.'public'.DS.'uploads');
        } else {
            dump($result);
        }
    }
