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。
演示
Usage
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();
Laravel 使用用例
routes
Route::group(['middleware' => ['web']], function () { Route::get('/login', function () { return view('login'); }); Route::post('/verify', function () { $captcha = new \Laravist\GeeCaptcha\GeeCaptcha(env('CAPTCHA_ID'), env('PRIVATE_KEY')); if ($captcha->isFromGTServer()) { if($captcha->success()){ return 'success'; } return 'no'; } if ($captcha->hasAnswer()) { return "answer"; } return "no answer"; }); Route::get('/captcha', function () { $captcha = new \Laravist\GeeCaptcha\GeeCaptcha(env('CAPTCHA_ID'), env('PRIVATE_KEY')); echo $captcha->GTServerIsNormal(); }); });
