vue使用axios接收流文件的实现_vue.js

// 导出
    const headers = response.headers
    //console.log(headers['content-type'])  将打印的值，也将后台返回的相应头设置成相同的，我的就是'application/octet-stream;charset=UTF-8',然后返回response
    if (headers['content-type'] == 'application/octet-stream;charset=UTF-8') {
        return response;
    }

this.axios({
   	method: "get",
    url: "/dafw/cljsdc",
    params: data,
    responseType: "blob"
  })
    .then(res => {
    let blob = new Blob([_res]);
    let downloadElement = document.createElement("a");
    let href = window.URL.createObjectURL(blob); //创建下载的链接
    downloadElement.href = href;
    downloadElement.download = "xxx.xls"; //下载后文件名
    document.body.appendChild(downloadElement);
    downloadElement.click(); //点击下载
    document.body.removeChild(downloadElement); //下载完成移除元素
    window.URL.revokeObjectURL(href); //释放掉blob对象
