如何優(yōu)雅的使用 laravel 的 validator驗(yàn)證方法

第如何優(yōu)雅的使用laravel的validator驗(yàn)證方法web開發(fā)過(guò)程中經(jīng)常會(huì)需要進(jìn)行參數(shù)驗(yàn)證，laravel中我們常用validator或者request這兩種方法來(lái)進(jìn)行驗(yàn)證，但是這兩種驗(yàn)證都不是很方便進(jìn)行自定義提示信息，自定義驗(yàn)證規(guī)則，所以下面來(lái)介紹一種很方便的用法：

新建抽象類

namespaceApp\Http\Validators;

useValidator;

abstractclassAbstractValidator

*Validator

*@var\Illuminate\Validation\Factory

protected$validator;

*Validationdatakey=valuearray

*@vararray

protected$data=array();

*Validationcodes

*@vararray

protected$codes=array();

publicfunction__construct(array$data)

$this-data=$data;

$this-before();

$this-validator=Validator::make($this-data,$this-rules,$this-messages);

$this-after();

*Setdatatovalidate

*@returnvalidator

publicfunctiongetValidator()

return$this-validator;

*Setdatatovalidate

*@return$this

publicfunctionwith(array$data)

$this-data=$data;

$this-before();

$this-validator=$this-validator-make($this-data,$this-rules,$this-messages);

$this-after();

return$this;

*Validationpassesorfails

*@returnboolean

publicfunctionpasses()

if($this-validator-fails()){

$this-errors=$this-validator-messages();

returnfalse;

returntrue;

return$this-rules;

*getData

publicfunctiongetData()

return$this-data;

return$this-errors;

*getMessages

publicfunctiongetMessages()

return$this-messages;

*setRule

*@paramstring$value

*@return$this

publicfunctionsetRule($key,$value)

$this-rules[$key]=$value;

return$this;

*emptyRules

publicfunctionemptyRules()

$this-rules=array();

return$this;

*sometimes

*@paramstring$attribute

*@paramstring|array$rules

*@return$this

publicfunctionsometimes($attribute,$rules,callable$callback)

$this-validator-sometimes($attribute,$rules,$callback);

return$this;

*resolver

*@paramClosure$resolver

*@return$this

publicfunctionresolver(Closure$resolver)

Validator::resolver($resolver);

return$this;

*replacer

publicfunctionreplacer($replace,Closure$resolver)

Validator::replacer($replace,$resolver);

return$this;

*extendImplicit

*@paramClosure$resolver

*@return$this

publicfunctionextendImplicit($extendImplicit,Closure$resolver)

Validator::extendImplicit($extendImplicit,$resolver);

return$this;

*extend

*@paramstring$rule

*@param\Closure|string$extension

*@paramstring$message

*@return$this

publicfunctionextend($rule,$extension,$message=null)

Validator::extend($rule,$extension,$message);

return$this;

*before(extend(),resolver())

*@return$this

publicfunctionbefore()

*after(sometimes())

*@return$this

publicfunctionafter()

新建中間件

namespaceApp\Http\Middleware;

useClosure;

use\Illuminate\Http\Request;

classValidateAdminMiddleware

*Thisnamespaceisappliedtothecontrollerroutesinyourroutesfile.

*Inaddition,itissetastheURLgenerator'srootnamespace.

*@varstring

protected$namespace='App\Http\Validators';

*Handleanincomingrequest.

*@param\Illuminate\Http\Request$request

*@param\Closure$next

*@returnmixed

publicfunctionhandle(Request$request,Closure$next,$validator=null)

if($request-isMethod('POST')){

$type=$request-segment(1);

if($validator){

$validator=$this-namespace.'\\'.studly_case($type).'\\'.studly_case($validator).'Validator';

$validator=new$validator($request-all());

if(!$validator-passes()){

if($request-isAjax()){

return$validator-errors()-first();

}else{

returnredirect()-back()

-withErrors($validator-getValidator())

-withInput();

return$next($request);

新建TestTestValidator

namespaceApp\Http\Validators\Admin;

useApp\Http\Validators\AbstractValidator;

classTestValidatorextendsAbstractValidator

*Validationrules

*@varArray

protected$rules=array(

'name'=['required','test','min:1'],

*Validationmessages

*@varArray

protected$messages=array(

'name.required'='必填',

'name.min'='最少1個(gè)字符',

'name.test'='測(cè)試',

*自定義驗(yàn)證規(guī)則或者擴(kuò)展Validator類
