mews/captcha 也适用于 API

1. 在 CaptchasController 里引入 mews/captcha

   ...
   use Mews\Captcha\Captcha;
   
   public function store(CaptchaRequest $request, Captcha $captcha)
   {
       $captchaInfo = $captcha->create('flat', true);
   }

第二个参数是表示api调用，此时方法会返回图片验证码的信息数组

    [
      'sensitive' => $generator['sensitive'],
      'key' => $generator['key'],
      'img' => $this->image->encode('data-url')->encoded
    ]

2. 在 VerificationCodesController 里验证图片二维码时可以调用 captcha_api_check 方法

   if(!captcha_api_check($request->captcha_code, $captchaData['captchaKey'])) {
       Cache::forget($request->captcha_key);
       $this->response->errorUnauthorized('验证码错误');
   }
