Laravel6.x使用验证码mews/captcha

Laravel6.x中使用验证，从安装到到使用一气呵成。验证码是一个必须用到的功能，因此，做个简单的记录吧。对于其他版本未进行测试，如Laravel8。

安装验证码包

composer require mews/captcha

注册

app/config/app.php

'providers' => [
    // ...
    'Mews\Captcha\CaptchaServiceProvider',
]

'aliases' => [
    // ...
    'Captcha' => 'Mews\Captcha\Facades\Captcha',
]        

配置

php artisan vendor:publish

执行该命令后出现如下选项阻塞执行

 Which provider or tag's files would you like to publish?:
  [0 ] Publish files from all providers and tags listed below
  [1 ] Provider: Facade\Ignition\IgnitionServiceProvider
  [2 ] Provider: Fideloper\Proxy\TrustedProxyServiceProvider
  [3 ] Provider: Illuminate\Foundation\Providers\FoundationServiceProvider
  [4 ] Provider: Illuminate\Mail\MailServiceProvider
  [5 ] Provider: Illuminate\Notifications\NotificationServiceProvider
  [6 ] Provider: Illuminate\Pagination\PaginationServiceProvider
  [7 ] Provider: Intervention\Image\ImageServiceProviderLaravelRecent
  [8 ] Provider: Laravel\Tinker\TinkerServiceProvider
  [9 ] Provider: Mews\Captcha\CaptchaServiceProvider
  [10] Tag: config
  [11] Tag: flare-config
  [12] Tag: ignition-config
  [13] Tag: laravel-errors
  [14] Tag: laravel-mail
  [15] Tag: laravel-notifications
  [16] Tag: laravel-pagination

输入 9 后会生成验证码配置文件app/config/captcha.php

视图使用验证码

案例

<img src="{{Captcha::src('default')}}">

完整案例：可刷新验证码

<div class="row cl">
    <div class="formControls col-xs-8 col-xs-offset-3">
        <input class="input-text size-L" name="code" type="text" placeholder="验证码"  value="" style="width:150px;">
        <img src="{{Captcha::src('default')}}" onclick="this.src=this.src+'?'+Math.random()" id="code">
        <a href="javascript:;" onclick="document.getElementById('code').onclick()">看不清，换一张</a>
    </div>
</div>

控制器中对验证码进行验证

表单请求验证

创建表单请求验证

php artisan make:request TestRequest

编写表单验证

// 一、改为true
public function authorize()
{
    return true;
}

// 二、编写规则
public function rules()
{
    return [
        'code'      =>  'required|captcha'
    ];
}

控制器中注入

// app/Http/Controllers/TestController.php

<?php
namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;
use App\Http\Requests\TestRequest;

class LoginController extends Controller
{
    public function test(TestRequest $request)
    {
    }

}
