是否可以使用node+express中的sendFile响应方式向客户端发送多张图片？

Question

我试图遍历一个图像目录的所有文件，但是当我从客户端访问路由时，图像相互交叉，我得到这个错误：

app.get(`/${SECRET_IMAGES_LOCATION}`, (req, res) => {
    fs.readdir(path.join(__dirname, "/img"), (err, files) => {
        if (err) return console.log(`Unable to open dir: `, err)
        
        files.forEach(file => {
            res.sendFile(path.join(__dirname, `/img/${file}`))
        })
    })
})

不可以，每个 HTTP 请求只能发送一个文件。它是 HTTP 协议。您访问一张 URL 并收到一张图片。
