使用 multer-s3 nodejs 将图像上传到亚马逊 s3

我正在尝试使用将图像上传到亚马逊 s3multer-s3，但我收到此错误：

类型错误：预期 opts.s3 为对象 node_modules/multer-s3/index.js:69:20

这是我的服务器代码：

var upload = multer({
    storage: s3({
        dirname: '/',
        bucket: 'bucket',
        secretAccessKey: 'key',
        accessKeyId: 'key',
        region: 'us-west-2',
        filename: function (req, file, cb) {
            cb(null, file.originalname); 
        }
    })
});

app.post('/upload', upload.array('file'), function (req, res, next) {
    res.send("Uploaded!");
});

为什么我会收到此错误？

[2022 年 3 月更新]到目前为止，它工作得很好，现在还显示上传的文件公共 URL。

Complete和工作节点作弊 |使用 multer-s3 上传到 s3 https://github.com/zishon89us/node-cheat/tree/master/aws/express_multer_s3可用的。

Code:

var express = require('express'),
    aws = require('aws-sdk'),
    bodyParser = require('body-parser'),
    multer = require('multer'),
    multerS3 = require('multer-s3');

aws.config.update({
    secretAccessKey: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX',
    accessKeyId: 'XXXXXXXXXXXXXXX',
    region: 'us-east-1'
});

var app = express(),
    s3 = new aws.S3();

app.use(bodyParser.json());

var upload = multer({
    storage: multerS3({
        s3: s3,
        acl: 'public-read',
        bucket: 'bucket-name',
        key: function (req, file, cb) {
            console.log(file);
            cb(null, file.originalname); //use Date.now() for unique file keys
        }
    })
});

//open in browser to see upload form
app.get('/', function (req, res) {
    res.sendFile(__dirname + '/index.html');//index.html is inside node-cheat
});

//use by upload form
app.post('/upload', upload.array('upl', 25), function (req, res, next) {
    res.send({
        message: "Uploaded!",
        urls: req.files.map(function(file) {
            return {url: file.location, name: file.key, type: file.mimetype, size: file.size};
        })
    });
});
  
app.listen(3000, function () {
    console.log('Example app listening on port 3000!');
});

对于完整的回购:

克隆节点作弊Express_multer_s3 https://github.com/zishon89us/node-cheat/tree/master/aws/express_multer_s3, run node app其次是npm install express body-parser aws-sdk multer multer-s3.

快乐帮助！
