vue2文件下载和合计表格

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

  
    
      {{ form.rentOrg }}
      {{ form.lesseeOrg }}
      {{ form.socialCode }}
      {{ form.startDate }}-{{ form.endDate }}
      {{ form.contractNo }}
      {{ form.contractName }}

vue2数据很多的时候需要后端

 下载导入模板

import { downloadFile } from "@/api/manage";

 api/manage代码如下

// import { axios } from '@/utils/request'
import axios from "@/utils/axios";
import signMd5Utils from "@/utils/encryption/signMd5Utils";

const api = {
  user: "/mock/api/user",
  role: "/mock/api/role",
  service: "/mock/api/service",
  permission: "/mock/api/permission",
  permissionNoPager: "/mock/api/permission/no-pager",
};

export default api;

//post
export function postAction(url, parameter) {
  let sign = signMd5Utils.getSign(url, parameter);
  //将签名和时间戳，添加在请求接口 Header
  let signHeader = {
    "X-Sign": sign,
    "X-TIMESTAMP": signMd5Utils.getDateTimeToString(),
  };

  return axios({
    url: url,
    method: "post",
    data: parameter,
    headers: signHeader,
  });
}

//post method= {post | put}
export function httpAction(url, parameter, method) {
  let sign = signMd5Utils.getSign(url, parameter);
  //将签名和时间戳，添加在请求接口 Header
  let signHeader = {
    "X-Sign": sign,
    "X-TIMESTAMP": signMd5Utils.getDateTimeToString(),
  };

  return axios({
    url: url,
    method: method,
    data: parameter,
    headers: signHeader,
  });
}

//put
export function putAction(url, parameter) {
  return axios({
    url: url,
    method: "put",
    data: parameter,
  });
}

//get
export function getAction(url, parameter) {
  let sign = signMd5Utils.getSign(url, parameter);
  //将签名和时间戳，添加在请求接口 Header
  let signHeader = {
    "X-Sign": sign,
    "X-TIMESTAMP": signMd5Utils.getDateTimeToString(),
  };

  return axios({
    url: url,
    method: "get",
    params: parameter,
    headers: signHeader,
  });
}

//deleteAction
export function deleteAction(url, parameter) {
  return axios({
    url: url,
    method: "delete",
    params: parameter,
  });
}

export function getUserList(parameter) {
  return axios({
    url: api.user,
    method: "get",
    params: parameter,
  });
}

export function getRoleList(parameter) {
  return axios({
    url: api.role,
    method: "get",
    params: parameter,
  });
}

export function getServiceList(parameter) {
  return axios({
    url: api.service,
    method: "get",
    params: parameter,
  });
}

export function getPermissions(parameter) {
  return axios({
    url: api.permissionNoPager,
    method: "get",
    params: parameter,
  });
}

// id == 0 add     post
// id != 0 update  put
export function saveService(parameter) {
  return axios({
    url: api.service,
    method: parameter.id == 0 ? "post" : "put",
    data: parameter,
  });
}

/**
 * 下载文件 用于excel导出
 * @param url
 * @param parameter
 * @returns {*}
 */
export function downFile(url, parameter, method) {
  return axios({
    url: url,
    params: parameter,
    method: method ? method : "get",
    responseType: "blob",
  });
}

/**
 * 下载文件
 * @param url 文件路径
 * @param fileName 文件名
 * @param parameter
 * @returns {*}
 */
export function downloadFile(url, fileName, parameter,method) {
  return downFile(url, parameter,method).then((data) => {
    // if (!data || data.size === 0) {
    //   Vue.prototype['$message'].warning('文件下载失败')
    //   return
    // }
    if (typeof window.navigator.msSaveBlob !== "undefined") {
      window.navigator.msSaveBlob(new Blob([data]), fileName);
    } 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
    }
  });
}

/**
 * 文件上传 用于富文本上传图片
 * @param url
 * @param parameter
 * @returns {*}
 */
export function uploadAction(url, parameter) {
  return axios({
    url: url,
    data: parameter,
    method: "post",
    headers: {
      "Content-Type": "multipart/form-data", // 文件上传
    },
  });
}

/**
 * 获取文件服务访问路径
 * @param avatar
 * @param subStr
 * @returns {*}
 */
export function getFileAccessHttpUrl(avatar, subStr) {
  if (!subStr) subStr = "http";
  try {
    if (avatar && avatar.startsWith(subStr)) {
      return avatar;
    } else {
      if (avatar && avatar.length > 0 && avatar.indexOf("[") == -1) {
        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"
      );
    },

合计

          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);
