我正在创建一个POST请求并验证image type。即使我正在jpeg中上传图像，但laravel仍然抛出{"message":"The photos must be a file of type: jpeg, jpg, png.","errors":{"photos":["The photos must be a file of type: jpeg, jpg, png."]}}。

** Postman 要求**

Laravel验证规则

public function rules()
{
    return [
        'photos' => ['required', 'mimes:jpeg,jpg,png', 'max:5']
    ];
}
