Process.env 不读取？ 亚马逊 S3 存储桶

Question

I'm trying to set my Amazon AWS access key and secret by using multer:

 var upload = multer({ secretAccessKey: process.env.AWS_ACCESS_SECRET, accessKeyId: process.env.AWS_ACCESS_KEY, })

In my zshrc file I've done

export AWS_ACCESS_SECRET="mysecret" export AWS_ACCESS_KEY="mykey"

however on running node, I get the error

 if (.opts secretAccessKey) throw new Error('secretAccessKey is required')

However hardcoding the key and secret makes it work, but obviously that's not the safest way to go.

I have done source ~/.zshrc but it still is showing the error.

Multer out of the box doesn't support s3. The way you're creating a new multer object is incorrect. The only available options when creating a new multer object are dest/storage , fileFilter and limits .

If you want to use Multer with S3 directly, you can use multer-s3 . With that you can pass in a new option storage that will take your secretAccessKey and your accessKeyId .

If you don't use multer-s3 you can use multer with aws-sdk 's S3 Client .

 var multer = require('multer'); var AWS = require('aws-sdk'); var accessKeyId = process.env.AWS_ACCESS_KEY; var secretAccessKey = process.env.AWS_ACCESS_SECRET; var upload = multer({dest: '/temp'}); var s3 = new AWS.S3({ accessKeyId: accessKeyId, secretAccessKey: secretAccessKey });
