Encapsulated in config/setting.js

fetchDownload(url, name = null) {
        let anchor = document.createElement('a');
        document.body.appendChild(anchor);

        let headers = new Headers();
        let filename = '';
        headers.append('Authorization', this.takeToken());
        fetch(url, { headers })
            .then(response => {
                filename = name ? name :
                    response.headers.get('Content-Disposition') ?
                    response.headers.get('Content-Disposition').split('=')[1] :
                    randstr();
                return response.blob();
            })
            .then(blobby => {
                let objectUrl = window.URL.createObjectURL(blobby);

                anchor.href = objectUrl;
                anchor.download = name === null ? decodeURI(filename) : filename;
                anchor.click();

                window.URL.revokeObjectURL(objectUrl);
                document.body.removeChild(anchor);
            });
    },

Then call it on the required page

import setting from '@/config/setting'

bind click export

<a-button type="primary"  size="small" class="ant-link" @click.prevent="exportExcel">导出</a-button>

export

 /**
     * 导出模板
     */
    const exportExcel = async() => {
      //调用封装好的方法进行必选参数校验
      if(!checkForm()) return
      let params = {
        companyId: setting.takeGroupId(),
        searchBeginTime: data.formData.searchBeginTime,
        searchEndTime: data.formData.searchEndTime,
        orgCodeList: data.formData.orgCodeList,
        direction: data.formData.direction,
      }
      const exportUrl = process.env.VUE_APP_API_BASE_URL + '/btyBank/export?' + Object.keys(params).map(key => `${key}=${params[key]}`).join('&')
      setting.fetchDownload(exportUrl)
    }

Required parameter verification

/** 检查表单 */
    const checkForm = () => {
      let flag = true
      if(data.formData.searchBeginTime == '') {
        message.error('请选择开始日期')
        flag = false
      }
      if(data.formData.searchEndTime == '') {
        message.error('请选择结束日期')
        flag = false
      }
      if(data.formData.orgCodeList.length == 0) {
        message.error('请选择组织机构')
        flag = false
      }
      return flag
    }
