vue+axios根据url下载文件

axios({
          method: 'get',
              url: music.value,
                    responseType: 'blob',
                }).then((res) => {
                    if (!res) {
                        return
                    }
                    let blobUrl = window.URL.createObjectURL(res.data);
                    let link = document.createElement('a');
                    document.body.appendChild(link);
                    link.style.display = 'none';
                    link.href = blobUrl;
                    link.download = music.name;
                    // 自触发click事件
                    link.click();
                    document.body.removeChild(link);
                    window.URL.revokeObjectURL(blobUrl);
      })

不需要后端修改求情头协议
