vue2文件数据不多可以直接下载不需要后端的时候

1.首先，确保你已经安装了 docx 和 file-saver 库

npm install file-saver
npm install docx file-saver

2.全部代码如下

<template>
  <a-modal
    title="详情"
    width="80%"
    v-model="visible"
    :confirmLoading="confirmLoading"
  >
    <a-descriptions title="" bordered>
      <a-descriptions-item label="出租方">{{ form.rentOrg }}</a-descriptions-item>
      <a-descriptions-item label="承租方">{{ form.lesseeOrg }}</a-descriptions-item>
      <a-descriptions-item label="统一社会信息代码">{{ form.socialCode }}</a-descriptions-item>
      <a-descriptions-item label="合同时间">{{ form.startDate }}-{{ form.endDate }}</a-descriptions-item>
      <a-descriptions-item label="合同编号">{{ form.contractNo }}</a-descriptions-item>
      <a-descriptions-item label="合同名称">{{ form.contractName }}</a-descriptions-item>
    </a-descriptions>
    <div class="table-operator">

      bordered
    >
      <span slot="action" slot-scope="text, record">
        <a v-if="record.payStatus == 1" @click="payment(record, false)">缴费</a>

      </span>
    </a-table>

vue2数据很多的时候需要后端

 <a-button type="primary" style="margin-left: 8px" @click="getExport"
        >下载导入模板</a-button
      >
import { downloadFile } from "@/api/manage";

 

 api/manage代码如下

// import { axios } from '@/utils/request'
import axios from "@/utils/axios";

  return axios({

}

//put
export function putAction(url, parameter) {

}

//get
export function getAction(url, parameter) {

  //将签名和时间戳，添加在请求接口 Header
  let signHeader = {

  return axios({

}

//deleteAction
export function deleteAction(url, parameter) {

  });
}

export function getServiceList(parameter) {
  return axios({

  });
}

export function getPermissions(parameter) {
  return axios({
    url: api.permissionNoPager,

}

// id == 0 add     post

export function saveService(parameter) {

}

/**

export function downFile(url, parameter, method) {

    responseType: "blob",
  });
}

/**

    if (typeof window.navigator.msSaveBlob !== "undefined") {

    } else {
      let url = window.URL.createObjectURL(new Blob([data]));
      let link = document.createElement("a");
      link.style.display = "none";
      link.href = url;
      link.setAttribute("download", fileName);
      document.body.appendChild(link);
      link.click();
      document.body.removeChild(link); //下载完成移除元素
      window.URL.revokeObjectURL(url); //释放掉blob对象
    }
  });
}

/**

/**

        return window._CONFIG["staticDomainURL"] + "/" + avatar;
      }
    }
  } catch (err) {
    return;
  }
}

 使用

  //导出模板
    getExport() {
      downloadFile(
        "/asset/entryrecord/exportTemplateXls",
        "财务信息模板.xlsx",
        {},
        "post"
      );
    },

          }
        })
        .catch((error) => {
          this.loading = false;
          console.error("Error fetching data:", error);
        });
    },

重点是

  this.dataSource.push(obj);

对象解构

第一种

let { foo, bar } = { foo: 'aaa', bar: 'bbb' };
    // 使用解构赋值简化对象创建过程
            const {
              bookMoney,
              transferWay,
              transferFinalOrg,
              receiveName,
              receiveType,
              evaluateMoney,
              transferMinPrice,
              dealMoney,
              moreMoney,
              signDate,
              remark,
            } = res.data;
 const obj = {
              isTotalRow: true,
              bookMoney,
              transferWay: "/",
              transferFinalOrg: "/",
              receiveName: "/",
              receiveType: "/",
              evaluateMoney,
              transferMinPrice,
              dealMoney,
              moreMoney,
              signDate: "/",
              remark,
            };

第二种

let { foo: baz } = { foo: 'aaa', bar: 'bbb' };
baz // "aaa"

const {
					data: res
				} = await uni.$http.get('/api/public/v1/goods/detail', {
					goods_id
				})
				console.log('res', res);
