数据字典格式返回：

以 teacherTypeObj 为例 向services.js中 lecturerExportExcel 方法中传入的格式为：

services.js中 lecturerExportExcel 导出方法：

import { request } from 'umi';
import { paramsFilter } from '../../utils/utils';
import ExportJsonExcel from 'js-export-excel';
import { message } from 'antd';


export async function lecturerExportExcel(params) {
  const { downloadTotal, downloadParams, orgObj2, teacherstateObj, teacherType, teacherTypeObj, setExportExcelLoading } = params;
  setExportExcelLoading(true);
  // 参数合并
  let newParams = Object.assign(downloadTotal, downloadParams);
  newParams.teacherType = teacherType;
  const result = await request('/api/Info/list2', {
    params: paramsFilter(newParams),
  });
  // 根据实际情况注释不需要导出的字段
  const allowExportColumns = [
    'manageCom',
    'name',
    'staffCode',
    'idNo',
    'mobile',
    "state",
    "teacherType"
  ];
  const TableItemObject = {
    manageCom: "管理机构",
    name: "姓名",
    staffCode: "工号",
    idNo: "证件号码",
    mobile: "移动电话",
    state: "讲师状态",
    teacherType: '讲师类别'
  };

  const cnColumns = allowExportColumns.map(kk => TableItemObject[kk]);
  if (Array.isArray(result?.data) && result?.data.length > 0) {
    const tableData = [];
    result?.data.forEach((item) => {
      const kv = {};
      Object.keys(item).map(vv => {
        if (allowExportColumns.includes(vv)) {
          // 数据字典字段汉化
          if (vv === 'manageCom') {
            kv[TableItemObject[vv]] = orgObj2[item[vv]] || '';
          } else if (vv === 'state') {
            kv[TableItemObject[vv]] = teacherstateObj[item[vv]] || '';
          } else if (vv === 'teacherType') {
            kv[TableItemObject[vv]] = teacherTypeObj[item[vv]] || '';
          } else {
            // 不用汉化直接输出
            kv[TableItemObject[vv]] = item[vv];
          }
        }
      })
      tableData.push(kv);
    });
    const option = {
      fileName: "讲师信息",
      datas: [
        {
          sheetData: tableData,// 数据
          sheetName: 'sheet1',
          sheetFilter: cnColumns,// 表头
          sheetHeader: cnColumns,// 表头
        }
      ]
    }
    const toExcel = new ExportJsonExcel(option);
    toExcel.saveExcel();
    setExportExcelLoading(false);
    return true;
  }
  message.error('数据为空！');
  setExportExcelLoading(false);
  return false;
}

utils 中 paramsFilter 方法：过滤无用参数文章来源地址https://www.toymoban.com/news/detail-701167.html

// 接口请求参数中 删除对象中值为空或null或undefined或者为空的所有属性
export function paramsFilter(requestParams) {
  let newParams = Object.keys(requestParams)
    .filter((key) => requestParams[key] !== null && requestParams[key] !== undefined && requestParams[key] !== '')
    .reduce((acc, key) => ({ ...acc, [key]: requestParams[key] }), {});
  return newParams;
}
