Laravel - 错误“传递给 Illuminate\Validation\Factory::make() 的参数 2 必须是数组类型，给定的对象”

Question

这段代码有什么问题？

class DeleteDetail extends FormRequest {

    public function authorize() {
        return true;
    }

    public function rules() {
        $request = Request::all();
        $rules = [
            'hobby' => [
                'string',
                'between:3,20',
                Rule::exists('user_hobby')->where(function ($query) use ($request) {
                    $query->where('hobby', $request['hobby'])->where('user_id', Auth::user()->id);
                }),
            ],
        ];

        return Validator::make($request, $rules);
    }

}

我得到的错误：

传递给 Illuminate\Validation\Factory::make() 的参数 2 必须是数组类型，给定的对象

您从rules方法本身内部返回了错误的值，您应该返回array containing your validation rules而不是Validation::make：

public function rules() {
    ...

    return $rules;
}
