Node.js 获取从multer生成的图像名称

我在用multer上传一个文件。上传很好，但我不知道如何获得生成的文件名。我想把它贴回回复中。已创建的文件名在注释中突出显示：

const storage = multer.diskStorage({
    destination: function (req, file, cb) {
        cb(null, '../app/src/assets/game/src/assets/images/')
    },
    filename: function (req, file, cb) {
        cb(null, file.fieldname + '-' + Date.now() + '.png') <!-- I need this in my postback response -->
    }
});

const upload = multer({ storage: storage }).single('avatar');

router.post('/upload/', function (req, res) {
    upload(req, res, function (err) {
        if (err) {
            // An error occurred when uploading
            throw err;
        }



        res.json({
            sucess: true,
            message: 'Image was uploaded successfully'
        });
        // Everything went fine
    })
});

const storage=multer.diskStorage({
目标：功能（请求、文件、cb）{
cb（空，“../app/src/assets/game/src/assets/images/”）
},
文件名：函数（请求、文件、cb）{
cb（null，file.fieldname+'-'+Date.now（）+'.png'）
}
});
const upload=multer（{storage:storage}）.single（'avatar'）；
router.post（'/upload/'，函数（req，res）{
上传（请求、恢复、功能（错误）{
如果（错误）{
//上载时出错
犯错误；
}
res.json({
是的，
消息：“图像已成功上载”
});
//一切都很顺利
})
});

要获取单个图像上载的图像名称，请使用

req.file.filename

：

res.json({
    success: true,
    message: 'Image was uploaded successfully',
    filename: req.file.filename
});

要获取多个图像上传的图像名称，请使用

req.files

：

let filenames = []
for(let i = 0; i < req.files.length; i++) {
    filenames.push(req.files[i].filename);
}
res.json({
    success: true,
    message: 'Image was uploaded successfully',
    filename: filenames
});

让文件名=[]
for（设i=0；i
