A simple Laravel 5/6/7 service provider for including the Captcha for Laravel.
for Laravel 4 Captcha for Laravel Laravel 4
本扩展包是基于mewbstudio的captcha(mews/captcha)兼容非session情况下开发的图形验证码机制。
The Captcha Service Provider can be installed via Composer by requiring the
charles/captcha
package and setting the minimum-stability
to dev
(required for Laravel 5) in your
project's composer.json
.
{
"require": {
"laravel/framework": "5.0.*",
"charles/captcha": "~3.1.0"
},
"minimum-stability": "dev"
}
or
Require this package with composer:
composer require charles/captcha
Update your packages with composer update
or install with composer install
.
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 charles/captcha
's dependencies.
To use the Captcha Service Provider, you must register the provider when bootstrapping your Laravel application. There are essentially two ways to do this.
Find the providers
key in config/app.php
and register the Captcha Service Provider.
'providers' => [
// ...
'Charles\Captcha\CaptchaServiceProvider',
]
for Laravel 5.1+
'providers' => [
// ...
Charles\Captcha\CaptchaServiceProvider::class,
]
Find the aliases
key in config/app.php
.
'aliases' => [
// ...
'Captcha' => 'Charles\Captcha\Facades\Captcha',
]
for Laravel 5.1+
'aliases' => [
// ...
'Captcha' => Charles\Captcha\Facades\Captcha::class,
]
To use your own settings, publish config.
$ php artisan vendor:publish
config/captcha.php
return [
'mode'=>'other', // 模式session或者其他任意值表示非session模式
'lifetime' => 120, // 有效期120秒,mode为session时此项无效
'default' => [
'length' => 5,
'width' => 120,
'height' => 36,
'quality' => 90,
'math' => true, //Enable Math Captcha
],
// ...
];
// [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 '<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;
});
captcha();
or
Captcha::create();
captcha_src();
or
Captcha::src('default');
captcha_img();
or
Captcha::img();
captcha_img('flat');
Captcha::img('inverse');
etc.
