Laravel 5模型$ cats到数组utf-8 JSON_UNESCAPED_UNICODE [英] Laravel 5 Model $cats to array utf-8 JSON_UNESCAPED_UNICODE

问题描述

当您拥有一个数组字段并将其保存在数据库中时，它将对数组执行一个漂亮的json_encode，但没有JSON_UNESCAPED_UNICODE选项.数据最终像这样:

When you have an array field and save it in the DB it does a nifty json_encode to the array but without the JSON_UNESCAPED_UNICODE option. The data end up like so :

<代码>{"en":"\ u039d \ u03ad \ u03b1"}

这几乎没有用.当然，解决方案是使用JSON_UNESCAPED_UNICODE标志对json_encode进行编码.是否可以告诉Laravel在保存模型之前添加此选项?

which is pretty much useless. The solution of course is to json_encode with the JSON_UNESCAPED_UNICODE flag. Is it possible to tell Laravel to add this option before saving the model?

我试图避免使用setNameAttribute mutator，因为每次我拥有这种类型的字段时，这样做都会很痛苦

I am trying to avoid using the setNameAttribute mutator as this would be kind of a pain to do it every time i have this type of fields

推荐答案

只需覆盖 asJson()方法.

class Cat extends Model
{

    // ...

    protected function asJson($value)
    {
        return json_encode($value, JSON_UNESCAPED_UNICODE);
    }

}

如果您不想对所有模型都重复该方法，只需将方法提取到抽象类中即可:

If you don't want to repeat the method for all your models, just extract the method to an abstract class:

abstract class UnicodeModel extends Model 
{
    protected function asJson($value)
    {
        return json_encode($value, JSON_UNESCAPED_UNICODE);
    }
}

现在，您继承自 UnicodeModel 而不是 Model :

Now you inherit from UnicodeModel instead of Model:

class Cat extends UnicodeModel 
{
    // ...
}

---

如果您需要更好的转换控件，则可以覆盖 setAttribute 方法，例如:

class Cat extends Model
{

    // ...

    public function setAttribute($key, $value)
    {

        // take special care for the attributes foo, bar and baz
        if (in_array($key, ['foo', 'bar', 'baz'])) {
            $this->attributes[$key] = json_encode($value, JSON_UNESCAPED_UNICODE);

            return $this;
        }

        // apply default for everything else
        return parent::setAttribute($key, $value);
    }
}
