视频教程: Laravist
说明：由于geetest本身的composer package有很多不必要的文件，这里是最精简的版本，只用于验证码验证。
安装 （目前的版本是 1.0）：
composer require laravist/geecaptcha
- 实例化
$captcha = new \Laravist\GeeCaptcha\GeeCaptcha($captcha_id, $private_key);- 使用的使用可以这样判断验证码是否验证成功（通常是post路由里）：
if ($captcha->isFromGTServer() && $captcha->success())
{
// 登录的代码逻辑在这里
}注意: 上面第一个判断是检测GT(geetest.com)的服务器是否正常，第二个才是检测验证码是否正确。
- 对于需要重新生成验证码的时候（通常放在get方式的路由里）：
$captcha = new \Laravist\GeeCaptcha\GeeCaptcha($captcha_id, $private_key);
echo $captcha->GTServerIsNormal();routes/web.php
Route::get('/captcha', function () {
$captcha = new \Laravist\GeeCaptcha\GeeCaptcha(env('CAPTCHA_ID'), env('PRIVATE_KEY'));
echo $captcha->GTServerIsNormal();
});
Auth::routes();
Route::get('/home', 'HomeController@index')->name('home');login视图:
