// 如果接口需要window.URL转码  可通过超链接直接下载

let url = `${base}/biz/internal/exportCsv?queryDtoStr=`;
                let enURL = window.encodeURI(url.concat(param));
                let link = document.createElement('a');

                document.body.appendChild(link);
                link.click();

//如果通过axios.get方式来导出数据，因为后台接口添加了 token验证
