问题描述
我正在尝试使用 multer-s3
将图像上传到 amazon s3,但出现此错误:
I am trying to upload an image to amazon s3 using multer-s3
, but I am getting this error:
TypeError:预期 opts.s3 为对象node_modules/multer-s3/index.js:69:20
TypeError: Expected opts.s3 to be object 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!");
});
为什么我会收到这个错误?
Why I am getting this error?
推荐答案
完成 和工作 节点作弊 |使用可用的 multer-s3 上传到 s3.
Complete and working Node Cheat | Upload to s3 using multer-s3 available.
代码:
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,
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',1), function (req, res, next) {
res.send("Uploaded!");
});
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,运行 node app
后跟 npm install express body-parser aws-sdk multer multer-s3
.
Clone node-cheat express_multer_s3, run node app
followed by npm install express body-parser aws-sdk multer multer-s3
.
