node.js - 有什么方法可以在 node.js 的客户端将字节数组转换为 blob 对象

Question

有没有办法在不实际下载文件的情况下从字节数组客户端获取 blob 对象

我想传递 blob 对象的客户端 =>

request.get('/api/get/video/blob/'+d1+'/'+d2+'/'+d3)
            .end((err, res) => {
                if (err) {
                   console.log("err="+err)
                } else {
                   console.log("data="+res)
                   if(res)
                   {
                    var uploadVideo = new UploadVideo();
                    uploadVideo.uploadFile(access_token,res// need actual blob object to pass @ res);  but what I get is byte array see following code 

服务器端=>

server.route({
        method: 'GET',
        path: '/api/get/video/blob/{d}/{s}/{x}',
        handler: function handler(request, reply) {
            const {d,s,x} = request.params;
            const key = d+'/'+s+'/'+x;
            var bucket = 're.render-previews';
            var params = {
            Bucket: bucket,
            Key: key
            };

         s3.getObject(params, function(err, data) {
            console.log("coming back");
            if (err) {
                console.log("err=>");
                console.log(err);
               // reject(err)
            } else {
                console.log("data=>");
                console.log(data);
                reply(data); // where I get byteArray 
            }
        });

    }
});

这行代码对我有用var blob = new Blob([new Uint8Array(BYTEARRAY)], { type: 'video/mp4' });
