    //这个函数是产生二维码
    public static function getImg($tradeNo, $title, $money)

        $order = new Order($attributes);
        $weChat = app('wechat');
        $payment = $weChat->payment;
        $result = $payment->prepare($order);
        if ($result->return_code == 'SUCCESS' && $result->result_code == 'SUCCESS') {
            $codeUrl = $result->code_url;
            $img = QrCode::size(300)->generate($codeUrl);
            return $img;
        }
        return false;

什么时候出个小程序的视频

https://tiicle.com/items/110/laravel-how-to-judge-a-property-in-the-model-the-listener-field-be-modified

https://stackoverflow.com/questions/38241424/laravel-5-model-cats-to-array-utf-8-json-unescaped-unicode

//Model设置好这个
protected $casts = [
        'tags' => 'json',
 ];

//新增数据
$input['tags']=['孩子','宝宝','成长'];
Article::create($input);

但是数据库存的是
["\u5b69\u5b50","\u5b9d\u5b9d","\u6210\u957f"]
有没有办法转为中文？
["孩子","宝宝","成长"]

a字段和b字段不能同时填写，怎么样验的

找到方法了吗？
