Marmelab react-admin x-total-count如何添加新标头

import axios from 'axios';

const apiUrl = 'https://api.example.com'; // 替换为实际的API地址

const httpClient = axios.create({
  baseURL: apiUrl,
});

// 添加拦截器，在请求发送前添加自定义标头
httpClient.interceptors.request.use((config) => {
  config.headers['x-total-count'] = '123'; // 替换为实际的资源总数
  return config;
});

const dataProvider = {
  // 实现各种CRUD操作方法...

  // 示例方法
  getList: (resource, params) => {
    const { page, perPage } = params.pagination;
    const url = `${resource}?_page=${page}&_limit=${perPage}`;

    return httpClient.get(url)
      .then((response) => {
        const totalCount = response.headers['x-total-count']; // 获取响应中的资源总数
        return {
          data: response.data,
          total: parseInt(totalCount, 10), // 将资源总数转换为数字
        };
      });
  },
};

export default dataProvider;
