[PHP知识库]laravel 自定义验证规则 重复利用

自定义laravel表单请求验证类(FormRequest共用一个rules())

class TeamDataPermissionRequest extends BaseRequest
{
    public $mid='';
    public $work_wechat=[];
    public function __construct()
    {
        $this->mid=Auth::user()->mid;
        $path = \Request::getPathInfo();
        $method = \Request::method();
        $path_method=$path.'/'.$method;
        // 根据路径判断验证场景
        switch ($path_method) {
            case '/api/workwechat/team/permission_member/POST':
                $this->scene = 'add';
                break;
            case '/api/workwechat/team/permission_member/PUT':
                $this->scene = 'put';
                break;
            case '/api/workwechat/team/permission_member/GET':
                $this->scene = 'get';
                break;
        }
    }
    /**
     * 验证规则
     *
     * @var array
     */
    protected $rules = [
        'default' => [],
        'add'     => [
            'name'=> 'required|filled',
            'email' => 'required|filled|email',
            'password'   => 'required|filled',
            'confirm_password'=> 'required|filled|same:password',
            'role' => 'required|filled',
            'channel'   => 'required|filled|array',
            'status'=> 'required|filled',
            'sale_uuid'=>'required|filled',
            'user_id'=>'required|filled',
        ],
        'put'=>[
            'name'=> 'required|filled',
            'email' => 'required|filled|email',
            'role' => 'required|filled',
            'channel'   => 'required|filled|array',
            'status'=> 'required|filled',
            'sale_uuid'=>'required|filled',
            'admin_id'=>'required|filled',
        ],
        'get'=>[
            'sales_uuid' => 'required|filled',
            'admin_id'=>'required|filled',
        ]
    ];

    protected $messages = [
        'add'=>[
"name.required" => "添加名称必填"
],
        'put'=>[
"name.required" => "名称必填"],
    ];

创建 基础request验证，根据路由和方法名使用不同的验证规则和验证提示信息

<?php

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class BaseRequest extends FormRequest
{
    /**
     * 验证规则场景
     *
     * @var string
     */
    protected $scene = 'default';

    /**
     * 验证规则
     *
     * @var array
     */
    protected $rules = [];

    /**
     * 验证错误消息
     *
     * @var array
     */
    protected $messages =[];

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return $this->rules[$this->scene];
    }

    /**
     * Get the validation messages that apply to the request.
     *
     * @return array
     */
    public function messages()
    {

        return $this->messages[$this->scene] ?? $this->messages;
    }
}

前后端分离的在App\Exceptions异常 中的??render方法加上验证导致抛出异常的处理 返回json

namespace App\Exceptions;



class Handler extends ExceptionHandler
{
public function render($request, Exception $exception)
    {
        if ($exception instanceof ValidationException) {
            $errors = $exception->errors();
            $errors = array_collapse($errors);
            $error  = array_first($errors);
            return response(['code' => RET_CODE_FAIL, 'message' => $error, 'data' => []], 200);
        }
}
