laravel验证码mewebstudio/captcha使用笔记！

gitHub地址：https://github.com/mewebstudio/captcha

使用demo：
composer引入包：composer require mews/captcha

 "require": {
        // ...
        "mews/captcha": "^3.0", 
    },

因为使用的laravel5.8版本，所以：

#config/app.php
providers' => [
        // ...
        Mews\Captcha\CaptchaServiceProvider::class,
    ]

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

发布配置文件php artisan vendor:publish,或者自建文件config/captcha.php,具体配置参考：vendor/mewebstudio/captcha/config/captcha.php

return [
    'default'   => [
        'length'    => 5,
        'width'     => 120,
        'height'    => 36,
        'quality'   => 90,
        'math'      => true, //Enable Math Captcha
    ],
    // ...
];

gitHub给出的demo,展示验证码图片和验证

    // [your site path]/Http/routes.php
    Route::any('captcha-test', function() {
        if (request()->getMethod() == 'POST') {
            $rules = ['captcha' => 'required|captcha'];
            $validator = validator()->make(request()->all(), $rules);
            if ($validator->fails()) {
                echo '
Incorrect!
';
            } else {
                echo '
Matched :)
';
            }
        }
    
        $form = '
';
        $form .= '';
        $form .= '
' . captcha_img() . '
';
        $form .= '
';
        $form .= '
Check
';
        $form .= '
';
        return $form;
    });

返回不同类型和配置，用于不同场景

返回Image

captcha();
Captcha::create();

返回URL

captcha_src();
Captcha::src('default');

返回HTML

captcha_img();
Captcha::img();

使用自定义配置

captcha_img('flat');

Captcha::img('inverse');
