vue3 get下载附件功能

实现思路，创建个a标签，触发一次点击事件，触发后删除a标签

export const fileDownloadFn = async (url) => {
    let downloadUrl = url;
    let elink = document.createElement("a");
    elink.download = name;
    elink.style.display = "none";
    // elink.target = "_blank";
    elink.href = downloadUrl;
    document.body.appendChild(elink);
    elink.click();
    document.body.removeChild(elink);
}
