谷歌隐形reCaptcha服务器端验证失败

我已经在我的应用程序中集成了隐形reCaptcha，客户端响应即将成为解决图像挑战的一部分 . 然后，我使用下面的代码调用角度函数来验证服务器端的用户响应 . 其中onloginSubmit（token）是成功回调 .

<button id="btnLogin" ng-disabled="loginForm.$invalid" 
                                class="g-recaptcha primarybtn margin-left-zero form-control-input"
                                data-sitekey="{{public_key}}"
                                data-callback='onloginSubmit'>{{'label_login' |
                                translate}}</button>

<script>
   function onloginSubmit(token) {
       angular.element(document.getElementById('loginForm')).scope().verifyReCaptcha(token);
   };
 </script>

在角度我正在调用verifyReCaptcha如下 .

$scope.public_key = "------ My Site Key -------";
  $scope.private_key = "------ My Secret Key -------";
  $scope.verifyReCaptchaURL = "https://www.google.com/recaptcha/api/siteverify";

$scope.verifyReCaptcha = function(reCaptchaToken){
       var captchaData = {
              secret : $scope.private_key,
              response : reCaptchaToken
      }

      $http({
          headers: {
            'Accept': 'application/json,text/plain',
            'Content-Type': 'application/json;application/x-www-form-urlencoded;charset=utf-8;',
          },
          url: $scope.verifyReCaptchaURL,
          method: 'POST',
          data: captchaData
        }).success(function (data) {
             console.log("success");
             $scope.login();
        }).error(function (data) {
             console.log("error");
             $window.location.reload(true);
        });
  };

当我点击api服务https://www.google.com/recaptcha/api/siteverify . 我得到以下错误 .

Failed to load https://www.google.com/recaptcha/api/siteverify: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8080' is therefore not allowed access. The response had HTTP status code 405.

我找不到更多关于这个问题的文档 .

什么是我做错了，如果有任何错误，recaptcha没有出现，我使用的登录按钮无法响应 .

在我提到Method as Post的请求时，该方法被覆盖，因为Options和我发送的请求有效负载不存在 . 这是我在网络标签中得到的
