tp6 验证 validate 用法

例子：给后端用户定义一个专属的验证类 User

1.定义规则和提示文字   User.php代码

<?php
namespace app\admin\validate;
use think\Validate;

class User extends Validate
{
    protected $rule =   [
        'username'  => 'require|chsAlphaNum|length:6,30',
        'password'   => 'require|length:6,30',
        'verifyCode'   => 'require|length:4',
        'email' => 'email',    
        'tel' => 'mobile|number|length:11',    
    ];
    
    protected $message  =   [
        'username.require' => '用户名必须填写',
        'username.chsAlphaNum'     => '用户名长度范围6-30个字符',
        'username.length'     => '用户名只能是汉字、字母和数字',
        'password.require'   => '密码必须填写',
        'password.length'   => '密码必须6-30个字符',
        'verifyCode.require'   => '验证码必须填写',
        'verifyCode.length'   => '验证码必须5位',
        'tel.mobile'  => '填写有效的手机',
        'tel.number'  => '手机只能数字',
        'tel.length'  => '手机只能11位数字',
        'email'        => '邮箱格式错误',    
    ];
    
}

2.控制器引用

要引用

use app\admin\validate\User;
use think\exception\ValidateException;

<?php
namespace app\admin\controller;
use think\facade\View;
// use think\db\Where;
use think\facade\Env;
use app\admin\validate\User;
use think\exception\ValidateException;

class Login 
{
    public function index()
    {
		return View::fetch();
    }
	
	
    public function login()
    {
		// $where = new Where;
		$sdf=env('CMS_PWD');
		// var_dump($sdf);exit;
		$username=input('post.username/s');
		$password=input('post.password');
		$verifyCode=input('post.verifyCode/s');
		// $username=input('post.username/s');
		try {
			//验证
            validate(User::class)->check([
                'username'  => $username,
                'password' => $password,
                'verifyCode' => $verifyCode,
            ]);
			
			if (request()->isAjax()){
				$rs = Db::name('admin')
				->field('username,password,realname,nickname,img,tel,email,department_id,department_id2,role_id,group_id,code_md5,enterprise_id')
				->where($where)
				->find();
			}else{
				throw new \Exception("非法提交");
			}
			$code=200;$msg='成功';
		} catch (ValidateException $e) {
			return ['code'=>-200,'msg'=>$e->getError()];
		} catch (\Exception $e) {
			// 这是进行异常捕获
			return ['code'=>-200,'msg'=>$e->getMessage()];
		}
		

		return json(['code' => $code,'msg' =>$msg]);
    }
	
}
