      axios.get(url,{params:{'path':path}, responseType:'blob'},).then((res)=>{
        let blob = new Blob([res.data], { type: `text/plain;charset=utf-8` });
        // 获取heads中的filename文件名
        let downloadElement = document.createElement("a");
        // 创建下载的链接
        let href = window.URL.createObjectURL(blob);
        downloadElement.href = href;
        // 下载后文件名
        downloadElement.download = file_name;
        document.body.appendChild(downloadElement);
        // 点击下载
        downloadElement.click();         // 下载完成移除元素
        document.body.removeChild(downloadElement);
        // 释放掉blob对象
        })
    }
