我已经开始使用AWS服务上传图像和上传时间它工作正常，但检索它不起作用

Question

我正在尝试传递API中的密钥，但作为回应，我不是该图像的URL。

我正在使用multer S3上传图片。

虽然上传该网址正在生成，但在GET API的共鸣中，它并未到来。

如何获取该网址。 以下是我的代码： -

＆＃13;

//node js code
var multer  = require('multer')
//var upload = multer({ dest: 'public/uploads/' });


var aws = require('aws-sdk');
var multerS3 = require('multer-s3');

aws.config.loadFromPath('./config.json');
aws.config.update({
    signatureVersion: 'v4'
});
var s0 = new aws.S3({})

var upload = multer({
    storage:multerS3({
        s3:s0,
        bucket:'bucketName',
        contentType: multerS3.AUTO_CONTENT_TYPE,
        acl: 'public-read',
        metadata: function (req, file, cb) {
            cb(null, {fieldName: file.fieldname});
        },
        key: function (req, file, cb) {
      cb(null, Date.now().toString())
    }
    })
})
//for posting
router.post('/profile/upload', upload.single('event_logo'), function(req, res, next){
    console.log("req.file",req.file);
    res.send(req.file);
});
//for retrieving
router.get('/profile/get/:id',function(req,res){
    var item = req.params.id;
    var params = {Bucket: 'bucketName', Key : req.params.id};
    s0.getObject(params, function (err, data) {
        if (err) {
            return res.send({ "error": err });
        }
        res.send({ data });
    });
});

//This is the response I am getting while hitting get Api
