vue通过接口直接下载java生成好的Excel表格案例

import axios from 'axios'
 
export const exportFile = params => {
 var param = new URLSearchParams()
 param.append('beginTime', params.beginTime)
 param.append('endTime', params.endTime)
 return axios({
  method: 'post',
  data: param,
  url: '/apis/downExcel',
  responseType: 'blob'
 })
}

downExcel() {
 var params = {
  beginTime: this.times[0],
  endTime: this.times[1]
 };
 exportFile(params).then(
  data => {
   /** 获取生成设置好的文件名 */
   var filename = data.headers["content-disposition"];
   filename = filename.split("=")[1];
   filename = decodeURIComponent(filename, "utf-8");
   /** 接收文件流 */
   const blob = new Blob([data.data]);
   let url = URL.createObjectURL(blob);
   /** 模拟浏览器操作Document，并模拟下载动作 */
   let link = document.createElement("a");
   link.style.display = "none";
   link.href = url;
   link.setAttribute("download", filename);
   document.body.appendChild(link);
   link.click();
  },
  error => {
   console.log(error);
   this.$message.error("下载异常，请稍后再试");
  });
}
