Laravel默认是没有提供验证码组件的,如果使用验证码需要自行安装:
推荐使用
mews/captcha
专门为laravel设计开发的拓展包。
1、composer引入安装
{
"require": {
"mews/captcha": "~2.0"
}
}或者使用下面的命令: composer require mews/captcha Update your packages with ```composer update``` or install with ```composer install```.

'providers' => [ // ... 'Mews\Captcha\CaptchaServiceProvider', ]
In Windows, you'll need to include the GD2 DLL `php_gd2.dll` in php.ini.
And you also need include `php_fileinfo.dll` and `php_mbstring.dll` to fit the requirements of `mews/captcha`'s dependencies.
配置所在目录:
config/captcha.php
2、example Usage
Route::any('captcha-test', function() {
if (request()->getMethod() == 'POST') {
$rules = ['captcha' => 'required|captcha'];
$validator = validator()->make(request()->all(), $rules);
if ($validator->fails()) {
echo '<p style="color: #ff0000;">Incorrect!</p>';
} else {
echo '<p style="color: #00ff30;">Matched :)</p>';
}
}
$form = '<form method="post" action="captcha-test">';
$form .= '<input type="hidden" name="_token" value="' . csrf_token() . '">';
$form .= '<p>' . captcha_img() . '</p>';
$form .= '<p><input type="text" name="captcha"></p>';
$form .= '<p><button type="submit" name="check">Check</button></p>';
$form .= '</form>';
return $form;
});3、使用示例
captcha(); //Return Image
Captcha::create(); //Return Image
captcha_src(); //Return URL
Captcha::src(); //Return URL
captcha_img(); //Return HTML
Captcha::img(); //Return HTML
Captcha::img('inverse'); //类型
captcha_img('flat');
