【问题描述】：

通常验证消息与我的 json 响应类似

"error_details": {
    "email": [
        "The email field is required."
    ],
    "password": [
        "The password field is required."
    ]
}

但我想做

"error_details": {
    "password": "The password field is required.",
"email": "The email field is required."
}

【解决方案1】：

你可以使用array_flatten()助手：

array_flatten($validator->getMessageBag()->getMessages());

这将返回所有验证器错误的一维数组。

【讨论】：

它将只返回数组中没有属性名称的消息。像 [ "这些字段是必需的。"]

【解决方案2】：

用途：

"error_details": {
"password.required": "The password field is required.",

"email.required": "email 字段为必填项。" } 它适用于 laravel 4

我确实偶然发现了同样的问题。这是我的做法

创建了一个扩展 Illuminate\Support\MessageBag 并覆盖 add 方法的 CustomMessageBag 类

<?php
namespace App\Extend;

use Config;
use Illuminate\Support\MessageBag as BaseMessageBag;

/**
 * Extending Validation Class
 *
 */

class CustomMessageBag extends BaseMessageBag{


     /**
     * Add a message to the bag.
     *
     * @param  string  $key
     * @param  string  $message
     * @return $this
     */
    public function add($key, $message)
    {
        if ($this->isUnique($key, $message)) {
            //remove additional array
            $this->messages[$key] = $message;
        }

        return $this;
    }

}

然后创建了一个使用CustomMessageBag 类的customValidator

<?php
namespace App\Extend;

use Input;
use Lang;
use Config;
use App\Extend\CustomMessageBag as MessageBag;


/**
 * Extending Validation Class
 *
 */

class CustomValidator extends \Illuminate\Validation\Validator {


    /**
     * Determine if the data passes the validation rules.
     *
     * @return bool
     */
    public function passes()
    {
        $this->messages = new MessageBag;

        // We'll spin through each rule, validating the attributes attached to that
        // rule. Any error messages will be added to the containers with each of
        // the other error messages, returning true if we don't have messages.
        foreach ($this->rules as $attribute => $rules) {
            foreach ($rules as $rule) {
                $this->validate($attribute, $rule);
            }
        }

        // Here we will spin through all of the "after" hooks on this validator and
        // fire them off. This gives the callbacks a chance to perform all kinds
        // of other validation that needs to get wrapped up in this operation.
        foreach ($this->after as $after) {
            call_user_func($after);
        }

        return count($this->messages->all()) === 0;
    }
}

最后在AppServiceProvider'sboot方法中注册CustomValidator类

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Extend\CustomValidator;
use Event;
use Mail;
use Config;
use Lang;
use Log;

class AppServiceProvider extends ServiceProvider {

    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot() {
        //Register custom validator class
        $this->app->validator->resolver(function($translator, $data, $rules, $messages) {
            return new CustomValidator($translator, $data, $rules, $messages);
        });
    }
}
