Node js 中的响应标头数据为 zip

我已经尝试使用此代码在标头中发送响应 zip，但我这边缺少一些内容。在此我得到的响应如屏幕截图所示

这是我的代码..

const zipPath - './test.zip'; // I have a zip with 2 files inside it (password protected)
    const stat = fs.statSync(zipPath);
    res.setHeader('Content-Disposition', 'attachment; filename=devices.zip');
    res.setHeader('Content-Type', 'application/octet-stream');
    res.setHeader('Content-Length', stat.size);
     res.writeHead(200, {
       'Content-Type': 'application/octet-stream',
       'Content-Disposition': 'attachment; filename=test.zip',
       'Content-Length': stat.size
     });

    let fileStream = fs.createReadStream(zipPath);
    fileStream.pipe(res);
    res.end();

看起来您可以发送数据，但编码不正确。在您的情况下，内容类型应该是“application/zip”，而不是“application/octet-stream”。

    const zipPath - './test.zip'; // I have a zip with 2 files inside it (password protected)
    const stat = fs.statSync(zipPath);
    res.setHeader('Content-Disposition', 'attachment; filename=devices.zip');
    res.setHeader('Content-Type', 'application/zip');
    res.setHeader('Content-Length', stat.size);
     res.writeHead(200, {
       'Content-Type': 'application/zip',
       'Content-Disposition': 'attachment; filename=test.zip',
       'Content-Length': stat.size
     });

    let fileStream = fs.createReadStream(zipPath);
    fileStream.pipe(res);
    res.end();
