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

use Validator;
 
...
 
Class .. {
 
public function ..(){
 
    Validator::make($input, $rules, $message, $attributes)->validate();
 
}

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(）。

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，

$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

/**
   * 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

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

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);
}

//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

//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，

Validator::extend('mobile', function($attribute, $value, $parameters) {
            return preg_match("/^1[34578]{1}\d{9}$/",$value);
        });
1
"font-size: 14px; line-height: 21px; white-space: normal">"font-family: "PingFang SC", "Helvetica Neue", Helvetica, Arial, sans-serif">这段代码应该很熟悉吧，不过到底放在哪里合适呢？我是这么做的

bootstrap/app.phpj加上
1
$app->register(App\Providers\Validate\ValidateServiceProvider::class);
1

然后创建对应服务类app/Providers/Validate/ValidateServiceProvider.php

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);
        });
      
    }
 
    /**

    public function register()
    {

}

      '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
