[英]Upload a file to AWS S3 using node js and Postman
I am new to AWS,and trying to figure out how to upload a file using the AWS S3 API ( http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html ), which is incorporated in my own api. 我是AWS的新手,并试图弄清楚如何使用AWS S3 API( http://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html )上传文件,自己的API。
I can create a bucket, and get a list of all the buckets- however I am struggling with a file upload. 我可以创建一个存储桶,并获取所有存储桶的列表,但是我正在努力上传文件。
This is by code: 这是通过代码:
router.post('/upload', function(req, res, next) {
var params = {
Bucket: req.body.bucketName,
Key: req.body.key,
Body: req.body.body
}
s3.putObject(params, function(err, data) {
if (err) {
return next(err)
} else {
res.json(data)
}
})
})
So when I run my server, I try to make a post request using postman to localhost:8080/upload
with the following: attaching a file, and the key and body - but I think I do this part wrong. 因此,当我运行服务器时,我尝试使用邮递员向localhost:8080/upload
发出以下请求:附加文件,密钥和主体-但我认为这部分做错了。
And I also attach the file: 而且我还附加了文件:
Question is: 问题是:
Do I correctly understand the following- Bucket
= the bucket name I want to upload to, Key
= the file name, Body
= the file contents? 我是否正确理解以下内容: Bucket
=我要上传到的桶名称, Key
=文件名, Body
=文件内容?
If yes, how do I get this to upload to S3 bucket, as with the current code I get a file added to s3 called ' text.txt
' with the contents ' heello
' rather than my ' test.txt
' file. 如果是,如何将其上传到S3存储桶,就像当前代码一样,我将添加到s3的文件名为text.txt
,其内容为heello
而不是test.txt
文件。
are you trying to upload a file correct? 您是否要正确上传文件? So you should use a multipart/form-data content-type, and in body you can point to your file buffer. 因此,您应该使用multipart / form-data内容类型,并且在正文中您可以指向文件缓冲区。
In my case, I use with swagger: 就我而言,我大摇大摆地使用:
upload: (req, res) => {
const params = {
Bucket: 'bucket-name',
Key: req.swagger.params.file.value.originalname,
ACL: 'public-read',
Body: req.swagger.params.file.value.buffer
};
s3.putObject(params, function(err, data) {
if (err) {
console.log('Error uploading image: ', err);
res.status(500).json().end();
} else {
res.status(200).json('File is uploaded').end();
}
})
}
