Codeigniter和MongoDB中的响应问题

Question

我有一个设置，要求对集合进行计数，但我总是收到

的错误

  

{“状态”：false}

我的模型如下：

public function count_users() {

        $query = $this->mongo_db->get('users');
        $row_count = count($query);

        $data = $row_count;

        $return = [
            'status' => true,
            'data'   => $data
        ];
    }

我的控制器就是这样：

// **
    // ** List Todays Stats for Admin Panel
    // **
    public function todaysstats_get() {
        //Validate user - logged in as admin -- session required
        $this->session_model->check_session();

        //Count Users
        $data           = $this->admin_model->count_users();

        $http           = $this->data_model->status_to_http_response($data['status']);
        $data['status'] = $http['status'];
        $http_response  = $http['http_response'];

        $this->set_response($data, $http_response);
    }

我正在使用GET方法来获取简单的计数返回数字

$route['v1/admin/todaysstats'] = 'v1/admin/todaysstats';

我尝试了几种不同的方法，但似乎并没有改变REST请求的状态。

$http = $this->data_model->status_to_http_response($data['status']);

的方法

 public function status_to_http_response($status) {

        // Select appropriate HTTP Response code, based on "status"
        // true  ---> 200
        // false ---> 422 (usually a validation error)
        // else  ---> use the value in "status" and set "status" to false.
        $status = intval($status);


        // If "true" send back a 200
        if ($status == 1) { 
            $http = REST_Controller::HTTP_OK;
            $status = true;
        }
        // If "false" send back a 422
        elseif ($status == 0) {
            $http = REST_Controller::HTTP_UNPROCESSABLE_ENTITY;
            $status = false;
        }
        // Otherwise use the status code given
        else {
            $http   = $status;
            $status = false;
        }

        return [
                'http_response' => $http,
                'status'        => $status,
                ];
    }
