我试图在angularjs文件中获取选择查询响应

Question

我想向angularjs文件发送Select查询响应。

Php file

header('Content-Type: application/json');    
echo json_encode(pg_fetch_row($res));



angularjs file

$http({
      method: 'GET',
      url: 'getData.php'
    }).then(function successCallback(response) {
        console.log(response);
        $scope.products= response.data;
      }, function errorCallback(response) {
        console.log(response);
      });

响应是Object {data: "↵ ", status: 200, config: Object, statusText: "OK", headers: function}

我怎样才能得到'数据'。这个符号“↵”是什么？
