Lumen开发:添加手机验证,中文验证与Validator验证的“半个”生命周期
今天来讲一下,Lumen的Validator函数
1 2 3 4 5 6 7 8 9 10 11 | use Validator; ... Class .. { public function ..(){ Validator::make( $input , $rules , $message , $attributes )->validate(); } |
1 | use Validator是可以直接引用的,虽然不能直接找到该命名空间的对应的位置。也可以直接在控制器 use 和使用Validator::make()。 |
1 | 至于类名和函数名就随意啦, $input 为传入验证的数组, $rule 为验证规则, $message 为返回的规则, $attributes 为验证字段的对应中文注释。废话少说,先模拟一个标准的数据, |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | $input = [ 'typeid' => 1, 'title' => '测试标题' , 'content' => '测试内容' ]; $rules = [ 'typeid' => 'required|numeric' , 'title' => 'required' , 'content' => 'required' ]; $message = [ "required" => ":attribute 不能为空" , "numeric" => ":attribute 格式不正确" ]; $attributes = [ 'typeid' => '分类id' , 'title' => '标题' , 'content' => '内容' ]; |
执行后,可能报错Illuminate\Validation\ValidationException: The given data failed to pass validation ...... vendor\illuminate\validation\Validator.php on line305
这是Lumen的异常处理机制,vendor\illuminate\validation\Validator.php
1 2 3 4 5 6 7 8 9 10 11 12 13 | /** * Run the validator's rules against its data.(运行验证的规则对数据。) * * @return void * * @throws \Illuminate\Validation\ValidationException */ public function validate() { if ( $this ->fails()) { throw new ValidationException( $this ); } } |
看看vendor\illuminate\validation\ValidationException.php
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | class ValidationException extends Exception { ... /** * Create a new exception instance.(创建一个新的异常实例。) * * @param \Illuminate\Contracts\Validation\Validator $validator * @param \Symfony\Component\HttpFoundation\Response $response * @return void */ public function __construct( $validator , $response = null) { parent::__construct( 'The given data failed to pass validation.' ); $this ->response = $response ; $this ->validator = $validator ; } |
直接这样抛出异常肯定不ok,接下看看解决方法,
方法一,异常拦截
进入app\Exceptions\Hanlder.php
1 2 3 4 5 6 7 8 9 | public function render( $request , Exception $e ) { //自带数据验证错误返回 if ( $e instanceof \Illuminate\Validation\ValidationException) { return $this ->handleValidationException( $request , $e ); } return parent::render( $request , $e ); } |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | //获取自带数据验证错误信息 protected function handleValidationException( $request , $e ) { $errors = @ $e ->validator->errors()->toArray(); $message = null; if ( count ( $errors )) { $firstKey = array_keys ( $errors )[0]; $message = @ $e ->validator->errors()->get( $firstKey )[0]; if ( strlen ( $message ) == 0) { $message = "An error has occurred when trying to register" ; } } if ( $message == null) { $message = "An unknown error has occured" ; } return $message ; } |
结果会返回第一个验证不过的对应信息。
不过直接在异常这里做处理不太合理,方法二
1 2 3 4 5 6 7 8 | //Validator::make($input, $rules , $message, $attributes)->validate(); $validator = Validator::make( $input , $rules , $message , $attributes ); $failed = $validator ->failed(); $messages = $validator ->messages(); if ( count ( $messages ) != 0){ dataReturn(1,current(current( $messages ))[0]); } |
调用failed和messages方法来处理会优雅许多!
接下来说一下大家关心的手机验证,
1 2 3 | Validator::extend( 'mobile' , function ( $attribute , $value , $parameters ) { return preg_match( "/^1[34578]{1}\d{9}$/" , $value ); }); |
1 |
|
1 | $app ->register(App\Providers\Validate\ValidateServiceProvider:: class ); |
1 |
然后创建对应服务类app/Providers/Validate/ValidateServiceProvider.php
1 |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 |
namespace App\Providers\Validate; use Validator; use Illuminate\Support\ServiceProvider; class ValidateServiceProvider extends ServiceProvider { /** * 启动应用服务 * * @return void */ public function boot() { Validator::extend( 'mobile' , function ( $attribute , $value , $parameters ) { return preg_match( "/^1[34578]{1}\d{9}$/" , $value ); }); } /** * Register any application services. * * @return void */ public function register() { } } |
加入手机验证
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | $input = [ 'typeid' => 1, 'title' => '测试标题' , 'content' => '测试内容' , 'phone' => '1881' ]; $rules = [ 'typeid' => 'required|numeric' , 'title' => 'required' , 'content' => 'required' , 'phone' => 'mobile' ]; $message = [ "required" => ":attribute 不能为空" , "numeric" => ":attribute 格式不正确" , "mobile" => ":attribute 手机格式不正确" ]; $attributes = [ 'typeid' => '分类id' , 'title' => '标题' , 'content' => '内容' , 'phone' => '联系方式' ]; |
就这样简单的实现了手机验证!
如果不想每次都传$message的话,可以看看这里\vendor\laravel\lumen-framework\resources\lang\en\validation.php
