先确保PHP扩展
php_gd2.dll

php_fileinfo.dll

这两个扩展开启
然后跑这个命令
composer require mews/captcha

接着配置
‘providers‘ => [
// ...
Mews\Captcha\CaptchaServiceProvider::class,
]

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

$ php artisan vendor:publish

这里的0表示安装所有的
config/captcha.php
return [ ‘default‘ => [ ‘length‘ => 5, ‘width‘ => 120, ‘height‘ => 36, ‘quality‘ => 90, ], // ... ];

最后用这个
captcha_src();

就可以显示验证码了
