laravel-验证码（前后端分离）

1.安装

composer require mews/captcha

2.获取验证码接口

$data = Captcha::create('default', true);
return $this->success($data);

 

 3.验证接口

//用户输入的验证码内容
$code = 'czuu';
//获取验证码接口返回的key
$key = '$2y$10$QcWWDaSscrJTxHYqxVQR/.OQxEBy20yA6cYmxeJTQjGZKqm3kBuOG';
if (!captcha_api_check($code, $key)) {
    return $this->fail(500, '验证码有误');
}
return $this->success();
