我已经从aws educate创建了aws帐户。我正在尝试将图片上传到AWS s3。但是我收到访问被拒绝的错误。

代码：

const multer = require('multer');
const multerS3 = require('multer-s3');
const config = require('../config');

aws.config.update({
  secretaccessKey: config.AWS_SECRET_accESS_KEY,accessKeyId: config.AWS_accESS_KEY_ID,region: 'us-east-1'
});

const s3 = new aws.S3();

const fileFilter = (req,file,cb) => {
  if (file.mimetype === 'image/jpeg' || file.mimetype === 'image/png' || file.mimetype === 'image/jpg') {
    cb(null,true);
  } else {
    cb(new Error('Invalid file type,only JPEG and PNG is allowed!'),false);
  }
}

const upload = multer({
  fileFilter,storage: multerS3({
    acl: 'private',s3,bucket: 'acc-partner',metadata: function (req,cb) {
      cb(null,{
        fieldName: 'TESTING_MetaDATA'
      });
    },key: function (req,Date.now().toString())
    }
  })
});

module.exports = upload;

const express = require('express');
const router = express.Router();
const UserCtrl = require('../controllers/user');

const upload = require('../services/image-upload');

const singleUpload = upload.single('image');


router.post('/image-upload',UserCtrl.authMiddleware,function(req,res) {
  singleUpload(req,res,function(err) {
    if (err) {
      return res.status(422).send({errors: [{title: 'Image Upload Error',detail: err.message}]});
    }

    return res.json({'imageUrl': req.file.location});
  });
});

module.exports = router;

邮递员错误

{
    "errors": [
        {
            "title": "Image Upload Error","detail": "access Denied"
        }
    ]
}
