Vue前端接收流写法

let config = {
  headers: {
    'Content-Type': 'application/json'
  },
  responseType:'blob',//必须要写
};

this.$http.post("/upms/api/v1/itim_doc/downloadFile", this.tableSelection, config).then(res => {//tableSelection参数，我自己的是对象，后台用List接，可以看一downloadFile接口
  let data = res.data;
  let contentDisposition = res.headers['content-disposition'];
  let fileName = contentDisposition.substring(contentDisposition.indexOf('=') + 1);
  let url = window.URL.createObjectURL(new Blob([data]));
  let edik = document.createElement('a');
  edik.style.display = 'none';
  edik.href = url;
  edik.setAttribute('download', fileName);
  document.body.appendChild(edik);
  //点击下载
  edik.click();
  // 释放掉blob对象
  window.URL.revokeObjectURL(edik);
  // 下载完成移除元素
  document.body.removeChild(edik);
});
