Question

我正在尝试将验证错误返回到角度，但我无法弄清楚如何在格式数组中返回它们（＆＃39;字段在验证＆＃39; =＆gt;＆＃39;错误消息＆＃39）。这个确切的数组保存在errors-＆gt; messages（）中，但它是受保护的属性。

这是我的代码

validator.php

<?php namespace TrainerCompare\Services\Validation;

use Validator as V;

/**
*
*/
abstract class Validator 
{
    protected $errors;

    public function validate($data)
    {
        $validator = V::make($data, static::$rules);

        if ($validator->fails()) {
            $this->errors = $validator->messages();

            return false;
        }

        return true;
    }

    public function errors()
    {
        return $this->errors;
    }
}

控制器

<?php

use TrainerCompare\Services\Validation\ProgramValidator;

class ProgramsController extends BaseController
{
    protected $program;
    protected $validator;

    public function __construct(Program $program, ProgramValidator $validator)
    {
        $this->program = $program;
        $this->validator = $validator;
    }
/**
     * Store a newly created resource in storage.
     *
     * @return Response
     */
    public function store()
    {
        $input = Input::all();

        $v = $this->validator->validate($input);

        if ($v == true) {
            //$this->program->create($input);

            return Response::json(
                array('success' => true)
            );
        } else {

            $errors = $this->validator->errors();

            return Response::json(
                array('errors' => $errors)
            );
        }
    }
}

这将返回json

{"errors":{}}

如果我将控制器更改为

$errors = $this->calidator->errors()->all();

返回

{"errors":["The title field is required.","The focus field is required.","The desc field is required."]}

我真正想要的是

{"errors":[title: "The title field is required.",focus: "The focus field is required.",desc: "The desc field is required."]}

Laravel中的Validator错误返回一个MessageBag对象，它有许多你可能想要查看的有用方法。

听起来你想要的是toArray方法，你可以在你的控制器中使用它。

替换控制器中的以下代码;

$errors = $this->validator->errors();

return Response::json(
    array('errors' => $errors)
);

使用;

$errors = $this->validator->errors()->toArray();

return Response::json(
    array('errors' => $errors)
);

或者，根据您如何使用Angular，您可以使用toJson方法直接返回对象。

return $this->validator->errors()->toJson();

将验证错误作为数组返回并更改为json
