I have loosened up CORS to the max from the Digital Ocean Spaces dashboard as seen in screenshot here - https://i.stack.imgur.com/8YrRI.png
I did this per the comment here - https://www.digitalocean.com/community/questions/can-i-upload-to-spaces-using-a-signed-url?comment=119654
I create a signed URL in backend like this:
import { S3Client as S3ClientConstructor } from '@aws-sdk/client-s3';
import { PutObjectCommand } from '@aws-sdk/client-s3';
import { getSignedUrl } from '@aws-sdk/s3-request-presigner';
const Spaces = new S3ClientConstructor({
endpoint: 'https://sfo2.digitaloceanspaces.com',
region: 'sfo2',
forcePathStyle: false,
credentials: {
accessKeyId: process.env.DO_ACCESS_KEY_ID,
secretAccessKey: process.env.DO_SECRET_ACCESS_KEY
}
});
const uploadUrl = await getSignedUrl(
Spaces,
new PutObjectCommand({
Bucket: 'my bucket',
ACL: 'public-read',
// Folder
Key: 'dev'
}),
{
// 10min
expiresIn: 600
}
);
I then upload from the HTML frontend file picker like this:
<input
className="hidden"
onChange={async function upload(e) {
setLoading(true);
if (!e.target.files?.length) {
// User canceled the file browser.
return;
}
try {
const uploadUrl = await fetchPresignedUrl();
const file = e.target.files[0];
const formData = new FormData();
formData.append('file', file);
const res = await fetch(uploadUrl, {
method: 'PUT',
body: formData,
headers: {
'Content-Type': file.type,
'x-amz-acl': 'public-read'
}
});
console.log('res.status:', res.status);
} finally {
setLoading(false);
}
}}
id="upload-button"
type="file"
/>
However this still gives me CORS error like this:
(Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 403.
The redacted presigned URL was:
https://MY_BUCKET_HERE.sfo2.digitaloceanspaces.com/dev?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Content-Sha256=UNSIGNED-PAYLOAD&X-Amz-Credential=******Faws4_request&X-Amz-Date=20230228T194311Z&X-Amz-Expires=600&X-Amz-Signature=***********&X-Amz-SignedHeaders=host&x-amz-acl=public-read&x-id=PutObject
Anyone have any ideas on how to fix this?
