I have problem with uploading photos to my AWS S3.
My code in angular 4 looks like this:
upload(input) {
let AWSService = window.AWS;
let file = input.target.files[0];
AWSService.config.update({
region: "us-east-1",
credentials: new AWS.CognitoIdentityCredentials({
IdentityPoolId: "us-east-1:XXXXXXXXXXXXXX"
})
});
let bucket = new AWSService.S3({
params: {
Bucket: "NAME"
}
});
let params = {
Key: file.name,
Body: file
};
bucket.upload(params, (res) => {
console.log(res);
});
}
require('aws-sdk/dist/aws-sdk');
Unfortunately, I am always receiving:
403 forbidden error.
What am I doing wrong?
403 Forbidden is coming from AWS S3. No problem with angular.
AWS documentation has a complete example of maintaining photo album with S3.
http://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/s3-example-photo-album.html
Hope it helps.

I have this code in my express server that generates an S3 presigned url using NodeJS AWS SDK:
const { S3Client } = require("#aws-sdk/client-s3");
const { getSignedUrl } = require("#aws-sdk/s3-request-presigner");
app.get('/getS3PresignedUrl', async (req, res) => {
const s3 = new S3Client({
region: 'ap-southeast-2',
credentials: {
accessKeyId: accessKey.data.access_key,
secretAccessKey: accessKey.data.secret_key
}
});
const presignedS3Url = await getSignedUrl(s3, new PutObjectCommand({
Bucket: 'xxx',
Key: 'test.txt',
})
);
res.send({
status: true,
message: 'success',
data: {
s3Url: presignedS3Url
}
});
})
Once I get the URL, I use that and put it in either curl or Postman but both gets 403 InvalidAccessKeyId.
For example:
curl
Postman
I don't understand why it fails with 403 when the S3 url is generated successfully? Note, I use that url right away and does not exceed the 900 seconds expire limit.
Any ideas what is the issue here?
Actually, this is the first time that I'm using s3 for uploading files. I have heard about pre-signed urls But apparently, I can't set a limitation for file size so I found "pre-signed post urls" but it's a little bit wierd!! Surprisingly I didn't find any example. maybe it's not what I want.
I'm getting pre-signed post url from the server:
const { S3 } = require("aws-sdk");
const s3 = new S3({
accessKeyId: accessKey,
secretAccessKey: secretKey,
endpoint: api,
s3ForcePathStyle: true,
signatureVersion: "v4",
});
app.post("/get-url", (req, res) => {
const key = `user/${uuri.v4()}.png`;
const params = {
Bucket: "bucketName",
Fields: {
Key: key,
ContentType: "image/png",
},
};
s3.createPresignedPost(params, function (err, data) {
if (err) {
console.error("Presigning post data encountered an error", err);
} else {
res.json({ url: data.url });
}
});
});
The weird thing is that the url that I get is not like a pre-signed url. it's just the endpoint followed by the bucket name. no query parameter. no option.
As you might guess, i can't use this url:
await axios.put(url, file, {
headers: {
"Content-Type": "image/png",
},
});
I do not even know if I should use post or two requests.
I tried both, Nothing happens. Maybe the pre-signed post url is not like pre-signed url!
At least show me an example! I can't found any.
You are on the right track, but you need to change the method you are invoking. The AWS S3 API docs of the createPresignedPost() that you are currently using states that:
Get a pre-signed POST policy to support uploading to S3 directly from an HTML form.
Try change this method to either getSignedUrl():
Get a pre-signed URL for a given operation name.
const params = { Bucket: 'bucket', Key: 'key' };
s3.getSignedUrl('putObject', params, function (err, url) {
if (err) {
console.error("Presigning post data encountered an error", err);
} else {
res.json({ url });
}
});
or synchronously:
const params = { Bucket: 'bucket', Key: 'key' };
const url = s3.getSignedUrl('putObject', params)
res.json({ url });
Alternatively, use a promise by executing getSignedUrlPromise():
Returns a 'thenable' promise that will be resolved with a pre-signed URL for a given operation name.
const params = { Bucket: 'bucket', Key: 'key' };
s3.getSignedUrlPromise('putObject', params)
.then(url => {
res.json({ url });
}, err => {
console.error("Presigning post data encountered an error", err);
});
Please also read the notes parts of the API documentation to make sure that you understand the limitations of each method.
any one please help me, by using express-fileupload library, I want to upload my file and image to AWS S3 bucket using restful API.
Hope you found the answer.
In case you haven't found the answer, here is what I just found out
const uploadSingleImage = async (file, s3, fileName) => {
const bucketName = process.env.S3_BUCKET_NAME;
if (!file.mimetype.startsWith('image')) {
return { status: false, message: 'File uploaded is not an image' };
}
const params = {
Bucket: bucketName,
Key: fileName,
Body: file.data,
ACL: 'public-read',
ContentType: file.mimetype,
};
return s3.upload(params).promise();
};
s3.upload(params).promise()
will return an object which contains the Location of the file you uploaded, in fact you could generate it yourself but that would not cover in case any error occur so I think what I posted here is a better solution.
Is there a way to do a multipart upload via the browser using a generated presigned URL?
Angular - Multipart Aws Pre-signed URL
Example
https://multipart-aws-presigned.stackblitz.io/
https://stackblitz.com/edit/multipart-aws-presigned?file=src/app/app.component.html
Download Backend:
https://www.dropbox.com/s/9tm8w3ujaqbo017/serverless-multipart-aws-presigned.tar.gz?dl=0
To upload large files into an S3 bucket using pre-signed url it is necessary to use multipart upload, basically splitting the file into many parts which allows parallel upload.
Here we will leave a basic example of the backend and frontend.
Backend (Serveless Typescript)
const AWSData = {
accessKeyId: 'Access Key',
secretAccessKey: 'Secret Access Key'
};
There are 3 endpoints
Endpoint 1: /start-upload
Ask S3 to start the multipart upload, the answer is an UploadId associated to each part that will be uploaded.
export const start: APIGatewayProxyHandler = async (event, _context) => {
const params = {
Bucket: event.queryStringParameters.bucket, /* Bucket name */
Key: event.queryStringParameters.fileName /* File name */
};
const s3 = new AWS.S3(AWSData);
const res = await s3.createMultipartUpload(params).promise()
return {
statusCode: 200,
headers: {
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Credentials': true,
},
body: JSON.stringify({
data: {
uploadId: res.UploadId
}
})
};
}
Endpoint 2: /get-upload-url
Create a pre-signed URL for each part that was split for the file to be uploaded.
export const uploadUrl: APIGatewayProxyHandler = async (event, _context) => {
let params = {
Bucket: event.queryStringParameters.bucket, /* Bucket name */
Key: event.queryStringParameters.fileName, /* File name */
PartNumber: event.queryStringParameters.partNumber, /* Part to create pre-signed url */
UploadId: event.queryStringParameters.uploadId /* UploadId from Endpoint 1 response */
};
const s3 = new AWS.S3(AWSData);
const res = await s3.getSignedUrl('uploadPart', params)
return {
statusCode: 200,
headers: {
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Credentials': true,
},
body: JSON.stringify(res)
};
}
Endpoint 3: /complete-upload
After uploading all the parts of the file it is necessary to inform that they have already been uploaded and this will make the object assemble correctly in S3.
export const completeUpload: APIGatewayProxyHandler = async (event, _context) => {
// Parse the post body
const bodyData = JSON.parse(event.body);
const s3 = new AWS.S3(AWSData);
const params: any = {
Bucket: bodyData.bucket, /* Bucket name */
Key: bodyData.fileName, /* File name */
MultipartUpload: {
Parts: bodyData.parts /* Parts uploaded */
},
UploadId: bodyData.uploadId /* UploadId from Endpoint 1 response */
}
const data = await s3.completeMultipartUpload(params).promise()
return {
statusCode: 200,
headers: {
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Credentials': true,
// 'Access-Control-Allow-Methods': 'OPTIONS,POST',
// 'Access-Control-Allow-Headers': 'Content-Type',
},
body: JSON.stringify(data)
};
}
Frontend (Angular 9)
The file is divided into 10MB parts
Having the file, the multipart upload to Endpoint 1 is requested
With the UploadId you divide the file in several parts of 10MB and from each one you get the pre-signed url upload using the Endpoint 2
A PUT is made with the part converted to blob to the pre-signed url obtained in Endpoint 2
When you finish uploading each part you make a last request the Endpoint 3
In the example of all this the function uploadMultipartFile
I was managed to achieve this in serverless architecture by creating a Canonical Request for each part upload using Signature Version 4. You will find the document here AWS Multipart Upload Via Presign Url
from the AWS documentation:
For request signing, multipart upload is just a series of regular requests, you initiate multipart upload, send one or more requests to upload parts, and finally complete multipart upload. You sign each request individually, there is nothing special about signing multipart upload request
So I think you should have to generate a presigned url for each part of the multipart upload :(
what is your use case? can't you execute a script from your server, and give s3 access to this server?
Good afternoon,
I'm trying to set up a connection to my aws product api, however I keep getting a 301 Permanent Redirect Error as follows:
{ [PermanentRedirect: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.]
message: 'The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.',
code: 'PermanentRedirect',
name: 'PermanentRedirect',
statusCode: 301,
retryable: false }
The code I am using to connect to the API is as follows:
var aws = require('aws-sdk');
//Setting up the AWS API
aws.config.update({
accessKeyId: 'KEY',
secretAccessKey: 'SECRET',
region: 'eu-west-1'
})
var s3 = new aws.S3();
s3.createBucket({Bucket: 'myBucket'}, function() {
var params = {Bucket: 'myBucket', Key: 'myKey', Body: 'Hello!'};
s3.putObject(params, function(err, data) {
if (err)
console.log(err)
else
console.log("Successfully uploaded data to myBucket/myKey");
});
});
If I try using different regions, like us-west-1 I just get the same error.
What am I doing wrong?
Thank you very much in advance!
I have fixed this issue:
You have to make sure that you already have created a bucket with the same name; in this case, the name of the bucket would be 'myBucket'.
s3.createBucket({Bucket: 'myBucket'}, function() {
var params = {Bucket: 'myBucket', Key: 'myKey', Body: 'Hello!'};
Once you created the bucket, go to properties and see what region it is using - add this into:
aws.config.update({
accessKeyId: 'KEY',
secretAccessKey: 'SECRET',
region: 'eu-west-1'
})
Now it should work! Best wishes
I've just come across this issue and I believe the example at http://aws.amazon.com/sdkfornodejs/ is incorrect.
The issue with the demo code is that Bucket names should be in lowercase - http://docs.aws.amazon.com/AmazonS3/latest/dev/BucketRestrictions.html
Had the demo actually output the err argument on the callback in s3.createBucket this would have been immediately obvious.
Also bucket names need to be unique in the region your creating them.
s3.createBucket({Bucket: 'mylowercaseuniquelynamedtestbucket'}, function(err) {
if(err){
console.info(err);
}else{
var params = {Bucket: 'mylowercaseuniquelynamedtestbucket', Key: 'testKey', Body: 'Hello!'};
s3.putObject(params, function(err, data) {
if (err)
console.log(err)
else
console.log("Successfully uploaded data to testBucket/testKey");
});
}
})
Was stuck on this for a while...
Neither setting the region name or leaving it blank in my configuration file fixed the issue. I came across the gist talking about the solution and it was quite simple:
Given:
var AWS = require('aws-sdk');
Prior to instantiating your S3 object do the following:
AWS.config.update({"region": "us-west-2"}) //replacing your region there
I was then able to call the following with no problem:
var storage = new AWS.S3();
var params = {
Bucket: config.aws.s3_bucket,
Key: name,
ACL:'authenticated-read',
Body: data
}
storage.putObject(params, function(storage_err, data){...})
