不，在服务器端（不管是什么语言），你不能在同一个请求中触发两个不同的下载。你可以通过javascript来实现，如下所示：

function downloadFile(file) {
    // Create a link and set the URL using `createObjectURL`
    const link = document.createElement("a");
    link.href = URL.createObjectURL(file);
    // the link is invisible so do not show on the page
    link.style.display = "none";
    // this ensures the file is downloaded even if is a html one
    // you can set to true, or specify with which name the file will be downloaded 
    link.download = file.name;

    // attach to the DOM so it can be clicked
    document.body.appendChild(link);
    // click the link
    link.click();
    // this should free memory, usefull if you download many
    // files without page reload
    URL.revokeObjectURL(link.href);
    // remove the link from the DOM
    document.body.removeChild(link);
}
